Full textAbstract:
Relatório de Estágio de Mestrado realizado sob a orientação do Doutor Carlos Fernando Almeida Grilo, apresentado à Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Leiria.Este documento visa explicar o trabalho que foi realizado para o projeto Web Vessel Tracker. Este projeto, proposto pela empresa XSealence S.A, foi realizado no âmbito da unidade curricular de Estágio do Mestrado em Engenharia Informática – Computação Móvel (MEI-CM) da Escola Superior de Tecnologia e Gestão (ESTG) do Instituto Politécnico de Leiria (IPL). O Web Vessel Tracker é um projeto que se enquadra na monitorização de embarcações com a qual se tenta resolver diversos problemas, como a pesca ilegal ou a sobrepesca. Estes são problemas que têm ganho bastante atenção, já que põem em causa a quantidade e variedade de peixe disponível numa determinada zona, o que pode levar a graves repercussões tanto a nível ambiental como económico. O Web Vessel Tracker, permite visualizar num mapa vários detalhes de embarcações que utilizam o dispositivo AIS e/ou MONICAP. A aplicação permite ainda obter informação relativa às rotas realizadas por uma embarcação, assim como, as capturas realizadas por esta. O Web Vessel Tracker serve para complementar o sistema proprietário de monitorização de embarcações já existente desenvolvido pela XSealence, o Centro de Controlo Integrado. O trabalho desenvolvido foca-se em utilizar tecnologias do lado do cliente para fazer a representação geográfica de informação relativa às embarcações, através de tecnologias de web mapping. Ao mesmo tempo, para obter essa informação, são utilizadas tecnologias do lado do servidor que depois a envia para o cliente.

Full textAbstract:
The orders of linkages that stabilise evolving media worlds are far from obvious. Often undertaken in media ‘laboratories’, the collaborative processes which combine a range of disciplines to develop media worlds are also far from straightforward. Enablers and constraints are as likely to be non-human as they are the people associated with the project. Plugs, wires, switches, protocols and standards - things whose detail can be mind numbingly boring - all have to be worked into effective and stable sets of associations. This thesis describes two knowledge pathways that track through such a project. The first describes the development of a prototype for a website, imagined as a portal for a range of interests around children and media in New Zealand/Aoteoroa. As media worlds are continually being reconfigured and as data circulates across increasingly linked access technologies, many non-government organisations are migrating their work to ‘the web’. ‘The Media Clearinghouse’ project was one of these. Latour’s analytical concept of immutable mobiles provides a way to make sense of some of the work observed whilst his direction to ‘simply follow’ worlds of interest provided the methodological challenge. The second pathway, traces the bibliographic threads of literatures that come from the descriptive genres of Science Technology Studies (STS). Significant amongst these are Leigh Star and Geoffrey Bowker who have elaborated the concept of boundary objects and infrastructures. Star and Griesemer’s seminal description of the Museum of Invertebrate Zoology is compared with a description of an early laboratory by Bruno Latour. These and other writers elaborate on methods that offer ways to render visible the messy, chaotic performances of design and invention. They follow inscriptions - tables, lists, maps, sketches and so on. These things work between the micro and the macro and enable very huge terrains to be assembled in small, ordered spaces. The thesis assembles a list of methods that have some utility for following and describing web design work and perhaps, other information worlds. Having followed and described this writer’s work through the invention of the prototype it is argued that a combinative method has successfully enabled a description that moves in and out of a new information ‘laboratory’.

Full textAbstract:
As a result of Web 2.0 technologies such as Asynchronous JavaScript and XML (Ajax) web-based applications with rich contents are evolving to be more and more like normal applications in aspects, such as interactivity, functionality, and usability. This evolvement makes it possible to create web-based services, providing maps for users to search and browse geographic information. This thesis is an evaluation of functionality, usability and accuracy for the four web-based map APIs: Google Maps, Microsoft Virtual Earth, Multimap and ViaMichelin.
The thesis explains how web-based mapping works, common functionality provided, and evaluates the functionality provided by each map service provider as well as the offered usability. In addition to this, it also includes the results of several tests, illustrating the APIs’ browser compatibility, performance and accuracy.
After testing and evaluation of the four APIs, the conclusion is that none of them can be appointed as the winner. They all have benefits and drawbacks; differences in terms of functionality, compatibility, usability, geocoding and development support, and the choice of API is consequently dependent of the type of application. As a result of this, and the fact that the APIs are constantly changing in terms of functionality and coverage, it is important to create applications independent of the map service provider. This was successfully done during the internship at Amadeus by creating a map abstraction layer in-between the applications and the maps, creating the possibility to switch API, or map service provider, without changed the code.

Full textAbstract:
The distribution of real-time GIS (Geographic Information System) data among users is now more important than ever as it becomes increasingly affordable and important for scientific and government agencies to monitor environmental phenomena in real-time. A growing number of sensor networks are being deployed all over the world, but there is a lack of solutions for their effective monitoring. Increasingly, GIS users need access to real-time sensor data from a variety of sources, and the data must be represented in a visually-pleasing way and be easily accessible. In addition, users need to be able to collaborate with each other to share and discuss specific sensor data. The real-time acquisition, analysis, and sharing of sensor data from a large variety of heterogeneous sensor sources is currently difficult due to the lack of a standard architecture to properly represent the dynamic properties of the data and make it readily accessible for collaboration between users. This thesis will present a JEE-based publisher/subscriber architecture that allows real-time sensor data to be displayed collaboratively on the web, requiring users to have nothing more than a web browser and Internet connectivity to gain access to that data. The proposed architecture is evaluated by showing how an AJAX-based and a Flash-based web application are able to represent the real-time sensor data within novel collaborative environments. By using the latest web-based technology and relevant open standards, this thesis shows how map data and GIS data can be made more accessible, more collaborative and generally more useful.

Full textAbstract:
Geographic Information Systems (GIS) development in crime analyses encourages sustainable platforms within various types of users and decision makers. Since patterns of crime incidents are pinpointed and analyzed in crime mapping, accurate data acquisition must be considered as a key concept to construct a successful GIS application.
Ankara City Police Department utilizes a semi-automated geocoding interface in which crime incidents including offenders and victims are pinpointed. However, this system has some accuracy errors during geocoding, because in this process point based data are located in the center of street line segments, and this may cause position errors up to 200 meters. Therefore, additional data editing must be done to reach a reasonable accuracy. In this context, real time data editing provides opportunity to gain time instead of expanding the GIS database within received hardcopy files from each police station. As the crime incidents occur daily, online editing must be used to maintain such an accurate and efficient spatial database.
In this study, for effective and accurate geocoding, a Web based data acquisition method is proposed. This online entry system enables real-time editing for GIS repository. In this way this study aims to provide a fast and reliable data acquisition system by constructing a multi participant platform enabling online data entry from each police station.

Full textAbstract:
Tsunamis, as the catastrophic disasters, can cause loss of live and property when they come to the shores. Preparation of emergency plans is essential to reduce the damage. Consequently, any initiative in tsunami modeling and inundation mapping is of vital importance for progressing safety surveillance and maintenance.
In an effort to achieve a thorough analysis of effect of tsunami, it is critical to estimate the geographical extent of possibly affected area and to predict tsunami impacts. The inundation mapping system also must serve to manage the simulation data in a scalable environment to reach end-users in the time of event. For this purpose, in this study, the generation of a Web based Geographic Information System (GIS) to serve inundation maps through web.
The research methodology consists of four main stages: (i) simulating tsunamis based on six different scenarios (ii) processing simulation data through a GIS application(iii) development of web interfaces and implementation of the developed model for Web-GIS application
(iv) verification of the created model for Marmara Sea Region. The proposed system is expected to be an efficient tool for improving inundation mapping efforts for expected tsunamis in Turkey.

Full textAbstract:
“Mashups” are web-based maps that intermix user-created data with information gathered
from multiple online sources. As part of the wave of “Web 2.0” technologies, mashups represent a shift toward distributed authoring and sharing of Internet content, complicating traditional modes of knowledge production. Mashups originated in the open source “hacker” movement and are now associated with the term “neogeography,” used to describe the practice of amateur mapmaking online.
In this thesis I ask whether mashups facilitate a cartography that is more accessible and democratic, studying the ways in which mashup authors create alternative community or personal cartographies while remaining dependent on existing power structures for data and resources. I illuminate these issues through a series of examples, such as: mashups that render personal memories about places, maps created by activist groups to counter dominant representations of geography by governments or corporations, and websites that facilitate the collaborative creation and sharing of spatial knowledge within community groups.
Contrasting these case studies with traditional paper cartography and GIS, as well as the professional online mapping technologies of the Geospatial Web (or GeoWeb), I explore how mashups attempt to represent personal, subjective, overlapping and contradictory perceptions of space and place. While enthusiastic claims about the ability of mashups to wrest mapmaking from state and corporate hands are currently overstated, I conclude that mashups do in fact provide new ways of collaboratively representing space whose implications are still to be determined.

Full textAbstract:
This thesis tackles two main questions: Why are networks important for civil society? And has the Internet (and in particular the Web) contributed to change civic networks and enhance their efficiency? This thesis follows a twofold strategy to make these questions operational: it draws, on the one hand, on a strictly inferential definition of Civil society, based on a random sampling of the organisations and actors that crowd the political domain, as configured on the Web; and it relies, on the other, on the network that these organisations build with their links to other organisations on the assumption that these citations provide information on alliances and partnerships. The analyses confirm that organisations follow different strategies in building their online connections, and that these strategies are not independent of the resources that organisations manage offline. Organisations that receive a higher number of links from other organisations are older, richer and with a better access to traditional media; they also have the most visited sites. Post-Internet organisations (those that were born with the Web) do not have any particular advantage in terms of visibility: they do not attract more links from other organisations, and they do not attract individuals searching the Web. The traffic flow of sites is significantly related to the centrality of organisations (that is, to how many other organisations link to them). The analyses identify two mechanisms underlying traffic flow: the impact of search engines' rankings on individual access to sites (rankings give more importance to sites with a higher number of incoming links), and the impact of offline visibility. The number of times organisations appear cited in the main international newspapers is positively correlated with the traffic flow of their sites and with their centrality. These results lead to three main conclusions: one, the Web has not radically changed the distribution of public exposure or empowered the poorest agents: publicising views is cheaper, but getting an audience stilI depends on the level of resources that the organisations publishing contents on the web manage offline; two, the Web grants nonetheless a (slightly) more equal visibility when compared to more traditional forms of media; and three, because of that, the Web plays a more efficient role in merging a diversity of views, preventing concentrations of power, and diffusing opportunities for mobilisation. In spite of this, the Web exhibits a tendency towards centralisation that might soon undermine its technical possibilities to tum the public sphere into a more plural space.

Rock, Nathaniel Robert. "Mapping geospatial events based on extracted spatial information from web documents." Thesis, University of Iowa, 2011. https://ir.uiowa.edu/etd/1068.
Full textAbstract:
Web documents such as news articles, social feeds, and blogs provide an abundant and readily available data source of spatial information relating to dynamic events such as wildfires, storms, and chemical spills. Research in the fields of geographic information retrieval and natural language processing use methods to extract place-names from web documents that can be used to geocode these events. However much of the spatial information in these articles are difficult to use because of the inherent vagueness of natural language. This thesis aims to develop methods to handle the vaguness of representing natural language descriptions of events by integrating precise spatial information (landmarks and geographic coordinates) with imprecise spatial information to provide a map-based visualization of the likely spatial extent and location of web document events.

Full textAbstract:
Accessibility and Interactivity are keywords of information today and that is equally important in science as anywhere else. When scientists share information it benefits if it is intuitive, informative and simple and does not demand expert skills in complicated formats. This master thesis has the aim to investigate open source software tools to design a web map application that can be used by any institute or NGO to distribute their data over internet. The Java platform to be implemented is the open source OpenLayers which allow users to view and potentially manipulate GIS map data through a web map application. Whatever GIS data made available on the Geoserver (the host site for the application) can be shared to users worldwide. The user can then: add from a list of available data layers, choose background (e.g. Google Earth, Open Street Map, etc.), zoom in and out, pan, change symbols and colors, add their own data on top and start animation (if applicable). The data distributed from the Geoserver can also be viewed and accessed from smartphones whichopens the possibility to make the public part of the larger data gathering task of specific scientific inventories like observations of migrating birds, or whatever indicator a specific scientist is interested in. Data is uploaded to the Geoserver and can then be analyzed and the result is distributed to the public.

Full textAbstract:
Ever increasing complexity of software systems, and distributed and dynamic nature of today’s enterprise level computing have initiated the demand for more self aware, flexible and robust systems, where human beings could delegate much of their work to software agents. The Semantic Web presents new opportunities for enabling, modeling, sharing and reasoning with knowledge available on the web. These opportunities are made possible through the formal representation of knowledge domains with ontologies. Semantic Web is a vision of World Wide Web (WWW) level knowledge representation system where each piece of information is equipped with well defined meaning; enabling software agents to understand and process that information. This, in turn, enables people and software agents to work in a more smooth and collaborative way. In this thesis we have first presented a detailed overview of Semantic web vision by describing its fundamental building blocks which constitutes famous layered architecture of Semantic Web. We have discussed the mile stones Semantic Web vision has achieved so far in the areas of research, education and industry and on the other hand we have presented some of the social, business and technological barriers in the way of this vision to become reality. We have also evaluated that how Semantic vision is effecting some of the current technological and research areas like Web Services, Software Agents, Knowledge Engineering and Grid Computing. In the later part of thesis we have focused on problem of ontology mapping for agents on semantic web. We have precisely defined the problem and categorized it on the basis of syntactic and semantic aspects. Finally we have produced a survey of the current state of the art in ontology mapping research. In the survey we have presented some of the selected ontology mapping systems and described their functionality on the basis of the way they approach the problem, their efficiency, effectiveness and the part of problem space they cover. We consider that the survey of current state of the art in ontology mapping will provide a solid basis for further research in this field.Ever increasing complexity of software systems, and distributed and dynamic nature of today’s enterprise level computing have initiated the demand for more self aware, flexible and robust systems, where human beings could delegate much of their work to software agents.

Ghidini, Marialaura. "Curating Web-based art exhibitions : mapping online and offline formats of display." Thesis, University of Sunderland, 2015. http://sure.sunderland.ac.uk/6088/.
Full textAbstract:
This dissertation investigates the theory and praxis of curating web-based exhibitions from the perspective of a practitioner (the author Marialaura Ghidini). Specifically, it investigates how the web as a medium of production, display, distribution and critique has had an impact on the work and research of independent curators and the way in which they configure their exhibition projects. With a focus on the last decade, curatorial work of production and commission is considered in relation to technological developments, previous theoretical work into the mapping of exhibitions online and the analysis of case studies which are paralleled with the author’s own exhibition projects. What has emerged from this combination of theory, practice and comparison of approaches is the rise of a tendency in contemporary curatorial practices online: the creation of exhibitions that migrate across sites—online and offline—and integrate different components—formats of display and distribution—giving life to exhibition models which this study names as those of the 'extended' and 'expanded'. The figure of the curator as mediating ‘node’ is another characteristic emerging in relation to this tendency. Its features are identified through the observation of six case studies, which include Beam Me Up, CuratingYouTube and eBayaday, and interviews with their curators, and three projects that the author organised with the web curatorial platform or-bits-dotcom, 128kbps objects (2012), (On) Accordance (2012) and On the Upgrade WYSIWG (2013), which experiment with modes of integrating web-based exhibition with other exhibition formats, such as the gallery show and print publishing. Through combining contextual review and curatorial practice, this study names the tensions existing between online and offline sites of display and modes of production and commission, offering critical and practical ground work to discuss the tendency of migrating exhibitions and integrating formats within the larger context of curating contemporary art.

Full textAbstract:
The development of web mapping industry is so fast that hundreds of web mapping software products are being created each year. These products are usually parts of three solution categories: a) proprietary solutions, b) Open source solutions, or c) Web 2.0 mashup solutions. Due to the solutions’ maturity, rich functionalities and great external support, most enterprises use proprietary products to build their web mapping applications. Seldom are the latter two, named as non-proprietary solutions in this study, ever used in corporations. This study explores the suitability of non-proprietary web mapping solutions for WSP Sweden.
Two prototype applications are developed using one Open source web mapping solution and one Web 2.0 mashup solution. Both applications attempt to accomplish similar tasks as an existing application, Stockholmshem tree inventory project, to demonstrate the functional potential of each solution. The implementation process will help to further access both prototype solutions on the basis of: a) how well they satisfy WSP’s list of demands; b) their implementation difficulty; and c) their response performances. The results indicate that both categories of non-proprietary solutions can satisfy the most important demands of WSP’s basic web mapping application. While Open source solutions are more suitable for meeting advanced demands, mashup solutions can help to quickly establish a simple application. The combinational use of both solutions is a promising alternative to the predominant ArcIMS-based proprietary solution used at WSP.

Web browsing posses a major share among the activities on the Internet. Heavy usage of web browsing makes the Web Quality of Experience (QoE) one of the critical factor in deciding the overall success of network services. Amongst others, Web QoE can be effected by the delays in network that can result in higher application download times. In this thesis work, an effort has been made to map applications level download times to Quality of Experience. A subjective analysis on how the user takes into account the domain of web browsing has been carried out. For this purpose a testbed was developed at Blekinge Institute of Technology on which different users were tested. Specific sequences of delays were introduced on the network which resulted in desired application download times. Regression analysis was performed and a mapping between user QoE and application download times was carried out. Based on the results conclusions were made which are presented in this thesis report.maxi_aks@hotmail.com Skype: ashfaq84 LinkedIn: www.linkedin.com/in/ashfaqahmadshinwary

Full textAbstract:
Within the last decade, the United States Forest Service (USFS) has initiated a nation-wide project of Sustainable Recreation as a response to the decreasing amount of resources available to maintain the current recreation infrastructure, including trails, campgrounds, etc. These unmaintained trails and facilities pose a potential safety threat to users and the landscape in which they reside. This smaller pilot project, as part of the Southeast Arizona Sustainable Recreation Strategy, is the second pilot project in the Southwest Region of the USFS aimed at growing the Sustainable Recreation initiative. The main goal of this project is to create the framework for an inter-agency web application of recreation opportunities in Southeast Arizona, with an aim to increase communication between land management agencies, and to increase public participation and conservation of public lands. To achieve this, recreation data were gathered from multiple participating agencies and merged into a new schema in order to provide useful attribute information. This schema was then uploaded to ArcGIS Online and saved as a web map for internal, agency use. In addition, a public-facing web application and corresponding Story Map were also created. The result better portrays the Sustainable Recreation initiative and provides a one-stop-shop of useful recreation information and links for users who wish to become more involved. This project provides the groundwork for which more data from additional agencies and areas can be added and the participation of both land management agencies and the general public can grow.

Previous issue date: 2010Um sistema para consultas espaciais visuais a Bancos de Dados Geográficos (BDG) é caracterizado pela utilização de representações gráficas que visam abstrair a sintaxe da linguagem de consulta do BDG. Web Mapping é um serviço disponibilizado na Web que permite a criação e visualização de mapas e rotas a partir de um Web site. Neste contexto, apesar da popularidade dos serviços de Web Mapping (e.g., Google Maps, Yahoo Maps e Bing Maps), estes não foram concebidos para realizar consultas espaciais (e.g. topológicas, métricas e direcionais) sobre BDG. Visando propor uma alternativa a esta limitação, esta dissertação especifica e implementa o sistema Visual Spatial Query (ViSQ) para, a partir de um serviço de Web Mapping, realizar consultas espaciais visuais sobre um BDG. O ViSQ faz uso de tecnologias abertas, extensíveis e de acordo com padrões consolidados, como Java, XML e SQL. Como avaliação do conceito, é realizado um estudo de caso com dados sobre o setor elétrico que mostra a viabilidade do sistema ViSQ

The first step of the data integration procedure includes data discovery, data retrieval, and data quality control of snow observations at ground stations. The WaterML R package developed in this work enables hydrologists to retrieve and analyze data from multiple organizations that are listed in the Consortium of Universities for the Advancement of Hydrologic Sciences Inc (CUAHSI) Water Data Center catalog directly within the R statistical software environment. Using the WaterML R package is demonstrated by running an energy balance snowpack model in R with data inputs from CUAHSI, and by automating uploads of real time sensor observations to CUAHSI HydroServer. The second step of the procedure requires efficient access to multi-temporal remote sensing snow images. The Snow Inspector web application developed in this research enables the users to retrieve a time series of fractional snow cover from the Moderate Resolution Imaging Spectroradiometer (MODIS) for any point on Earth. The time series retrieval method is based on automated data extraction from tile images provided by a Web Map Tile Service (WMTS). The average required time for retrieving 100 days of data using this technique is 5.4 seconds, which is significantly faster than other methods that require the download of large satellite image files. The presented data extraction technique and space-time visualization user interface can be used as a model for working with other multi-temporal hydrologic or climate data WMTS services. The third, final step of the data integration procedure is generating continuous daily snow cover maps. A custom inverse distance weighting method has been developed to combine volunteer snow reports, cross-country ski track reports and station measurements to fill cloud gaps in the MODIS snow cover product. The method is demonstrated by producing a continuous daily time step snow presence probability map dataset for the Czech Republic region. The ability of the presented methodology to reconstruct MODIS snow cover under cloud is validated by simulating cloud cover datasets and comparing estimated snow cover to actual MODIS snow cover. The percent correctly classified indicator showed accuracy between 80 and 90% using this method. Using crowdsourcing data (volunteer snow reports and ski tracks) improves the map accuracy by 0.7 – 1.2 %. The output snow probability map data sets are published online using web applications and web services.

Full textAbstract:
Groundwater is used worldwide as a major source for agricultural irrigation, industrial processes, mining, and drinking water. An accurate understanding of groundwater levels and trends is essential for decision makers to effectively manage groundwater resources throughout an aquifer, ensuring its sustainable development and usage. Unfortunately, groundwater is one of the most challenging and expensive water resources to characterize, quantify, and monitor on a regional basis. Data, though present, are often limited or sporadic, and are generally not used to their full potential to aid decision makers in their groundwater management.This thesis presents a solution to this under-utilization of available data through the creation of an open-source, Python-based web application used to characterize, visualize, and quantify groundwater resources on a regional basis. This application includes tools to extrapolate and interpolate time series observations of groundwater levels in monitoring wells through multi-linear regression, using correlated data from other wells. It is also possible to extrapolate time series observations using machine learning techniques with Earth observations as inputs. The app also performs spatial interpolation using GSLIB Kriging code. Combining the results of spatial and temporal interpolation, the app enables the user to calculate changes in aquifer storage, and to produce and view aquifer-wide maps and animations of groundwater levels over time. This tool will provide decision makers with an easy to use and easy to understand method for tracking groundwater resources. Thus far, this tool has been used to map groundwater in Texas, Utah, South Africa, Colombia, and the Dominican Republic.

Data maps serve the purpose of visually representing information. They are especially useful for
allowing people to grasp complex data structures. An interactive data map adds the functionality
of people and systems being able to interact with the data through the use of the data map. This
interaction may include navigation through parts of data structures or physically manipulating
the underlying data.
In this study the feasibility of utilising an interactive data map implemented for the purpose
of energy management in industries, such as gold mining and cement manufacturing, is taken
under consideration. The interactive data map forms part of a complete energy management

Full textAbstract:
The rigorous developments of GIS over the past decades have enabled application developers to create powerful systems that are used to facilitate the management of spatial data. Unfortunately, each one of these systems is specific to a local service, with little or no interconnection with services in other locales. This makes it virtually impossible to perform dynamic and interactive GIS operations across multiple locales which have similar or dissimilar system configurations. The Spatial Data Transfer Standard (SDTS) resolved the problems partially by offering excellent conceptual and logical abstraction model for data exchange. Recent advancements of the Internet enlightened the GIS community as to the realization of an ideal concept of information interchange. A suite of new technologies that embraces Extensible Markup Language (XML), Scalable Vector Graphics (SVG), Portable Network Graphics (PNG) and Java creates a powerful and new perspective that can be applied to all phases of online GIS system development. The online GIS is a Web-based approach to integrating diverse spatial data sources for GIS applications. To address the spatial data integration options and implications related to the Web-based approach the investigation was undertaken in 5 phases: (1) Determine the mapping requirements of graphic and non-graphic spatial data for online GIS application; (2) Analyze the requirements of spatial data integration for online environments; (3) Investigate a suitable method for integrating different formats of spatial data; (4) Study the feasibility and applicability of setting up the online GIS; and (5) Develop a prototype for online sharing of teaching resources. Resulting from the critical review on current Internet technology, a conceptual framework for spatial data integration was proposed. This framework was based on the emerging Internet technology on XML, SVG, PNG, and Java. It was comprised of four loosely coupled modules, namely, Application Interface, Presentation, Integrator, and Data module. This loosely coupled framework provides an environment that will be independent of the underlying GIS data structure and makes it easy to change or update the system as a new task or knowledge is acquired. A feasibility study was conducted to test the applicability for the proposed conceptual framework. A detailed user requirements and system specification was thus devised from the feasibility study. These user requirements and system specification provided some guidelines for online GIS application development. They were expressed specifically in terms of six aspects: (1) User; (2) Teaching resources management; (3) Data; (4) Cartography; (5) Functions; and (6) Software development configuration. A prototype system based on some of the devised system specifications was developed. In the prototype software design, the architecture of a Three-Tier Client-Server computing model was adopted. Due to the inadequacy of native support for SVG and PNG in all currently available Web browsers, the prototype was thus implemented in HTML, Java and vendor specific vector format. The prototype demonstrated how teaching resources from a variety of sources and format (including map data and non-map resources) were integrated and shared. The implementation of the prototype revealed that the Web is still an ideal medium for providing wider accessibility of geographical information to a larger number of users through a corporate intranet or the Internet cost-effectively. The investigation concluded that current WWW technology is limited in its capability for spatial data integration and delivering online functionality. However, developing of XML-based GIS data model and graphic standards SVG and PNG for structuring and transferring spatial data on the Internet appear to be providing solutions to the current limitations. It is believed that the ideal world where everyone retrieving spatial information contextually through a Web browser disregarding the information format and location will eventually become true.

Full textAbstract:
The subject of the report is to review and evaluate the potential for vector graphics in web maps. It ishoped that a web mapping only should display vector graphics. Compared to the traditional webmapping approach, that has raster tiles pre-rendered on the server side for each zoom level. Thedrawback with raster data is that it lacks in information content compared to vector data, which interms can contribute to a richer user interface. However, vector graphics, in comparison to raster datahave a complex data structure and are inefficient to handle such as raster data traditionally is managed.Thanks to new rendering techniques for vector graphics, such as by VML, SVG, but mainly throughthe canvas element, web maps can be improved since vector graphics can be drawn directly in theclient through the browser without the need to generate data on the server side and sent it to the client.By selecting three vector-based mobile mapping libraries that use HTML5, in particular the canvaselement, each library is examined and evaluated based on their ability to use vector graphics, bothperformance-wise, by randomly generating vector data on a map comprising of the world, but alsoaccording to a number of usability criteria. Thereafter, a mobile travel habit implementation isdeveloped based on one of the libraries that meets the criteria the best. The travel habit application isdesigned to register the user’s geographical movements and subsequently display the user’s completedtrip in terms of vector data on a map. The application is developed with the ASP.NET technique thatconsists of HTML, JavaScript and C# languages. Results show that each library is superior / comparesfavourably to the others for at least one of the assessment criteria. Based on the performance test forthe rendering of vector data, the Tile5 library performed best with a rendering time corresponding toapproximately half the time it took for the second best library Leaflet. However, since Tile5 indicatesdeficiencies in the documentation, Leaflet fits the overall established assessment criteria best and isselected for the implemented of the mobile application for travel habits. For future development, Tile5has the potential to become a useful and effective tool for vector web mapping and to compete withthe traditional mapping platforms that renders raster data.Motivet till rapporten är att granska och utvärdera möjligheterna för vektorgrafik i webbkartor,förhoppningen är att i en webbkarta endast visa vektorgrafik. Istället för på det traditionella sättet medraster data som genererats färdigt på server-sidan för varje zoom-nivå av kartan. Nackdelen medrasterdata är att den är fattig på information jämfört med vektordata, som i sin tur kan bidra till ettrikare användargränssnitt. Dock har vektorgrafik jämfört med rasterdata en komplex datastruktur ochär ineffektivt att hantera så som rasterdata traditionellt görs.Tack vare nya rittekniker för vektorgrafik, så som genom VML, SVG men främst via canvaselementet, kan webbkartor förbättras i och med att vektorgrafik kan ritas upp direkt genom browserutan att behöva generera data på server-sidan. Genom att välja ut tre vektor-baserade utvecklingsbibliotek som använder sig utav HTML5 och speciellt canvas elementet, så undersöks och utvärderasrespektive bibliotek utifrån deras möjlighet att använda vektorgrafik, både prestandamässigt, genomatt slumpmässigt generera vektor data på en karta omfattande av hela världen, men också utifrån ettantal användbarhetskriterier. Därefter utvecklas en test implementation, d.v.s. en applikation för resvanor,baserat på den utav biblioteken som uppfyller kriterierna bäst. Res-vane applikationen ärinriktad på att registrera användarens geografiska rörelser och kan sedan visa användarens genomfördaresa i form av vektordata på en karta. Applikationen är utvecklad med ASP.NET tekniken som bestårutav HTML, JavaScript och C# språken. Resultatet från den empiriska undersökningen visar attkartbiblioteken utmärker sig på förmånligt men på olika områden. Utifrån prestandatestet förrendering av vektordata, presterade Tile5 bibliotek bäst med en renderingstid motsvarande ungefärhäften av tiden det tog för det näst bästa biblioteket, Leaflet. Dock ledde bristande dokumentation förTile5 till att Leaflet, till det stora hela sett, passade bedömningskriterierna bäst och kom attimplementeras i den mobila test applikationen för resvanor. För framtida utvecklings, har Tile5potential att utvecklas till ett användbart och effektivt verktyg för vektorkartläggning och för attkonkurrera med traditionella webbkartor som renderar rasterdata.

Foi estruturado um modelo de servidor de mapas, na plataforma MapGuide, capaz de disseminar eletrônicamente os dados geoespaciais gerados pela Prefeitura de Taboão da Serra SP. O projeto de servidor visou duas finalidades principais: implementar este tipo de tecnologia ao analista responsável pelo projeto, no âmbito da Prefeitura, e; tornar a dissertação um guia teóricometodológico introdutório a profissionais da Cartografia e Geociências, não especializados com este ramo das geotecnologias. O serviço de disseminação foi configurado para servir dados geoespaciais diretamente a navegadores de rede, servidores FTP e Sistemas de Informação Geográfica (SIG). Para estes últimos, foram utilizados recursos de acesso a dados localizados em servidores de mapas remotos, por meio dos serviços de Web Mapping Service (WMS) e Web Feature Service (WFS). Enquanto a disseminação em navegador de rede pode alcançar usuários não especializados com este campo das geotecnologias, a utilização de servidores FTP, serviços WMS e WFS remotos, favorece usuários técnicos das Geociências e Cartografia. Comparou-se as funcionalidades do MapGuide, a SIG de primeira e segunda geração, com funções topológicas completas. Concluiu-se que o servidor de mapas não possuía a mesma capacidade de análise espacial dos SIG topológicos.A Web Mapping application built on MapGuide was designed to digitally serve the municipal government of Taboão da Serra SP geospatial data. There were two aims related to the application project: to implement the technology to the analyst responsible for the project, and; to develop the project content as an introdutory theoretical-methodological guide to geoscientists and cartographers not specialized in the internet mapping field. The geospatial data dissemination services were configured to web browsers, FTP servers and Geographic Information Systems (GIS). For these lasts, data access resources to remote spatial servers were used, via Web Mapping Services (WMS) and Web Feature Services (WFS). While the web browser data dissemination is suitable for non-technicians, the FTP server, WMS and WFS resources, are best suitable for GIS analysts. A comparison between MapGuide functionalities with other first and second generation topological GIS softwares was performed. The conclusion revealed the web mapping application didn\'t have the same spatial analysis capabilities as the topological GIS.

Full textAbstract:
“Know what people think”. Ce slogan, affiché sur la page d’accueil du site de l’entreprise britannique Brandwatch, résume à lui seul la promesse de l’industrie nouvelle associée à l’étude des opinions sur le web : savoir enfin ce que les gens pensent, et cela sans même avoir besoin de le leur demander. Un ensemble d’agences, de start-ups et d’éditeurs de logiciels propose en effet depuis le milieu des années 2000 de connaître les opinions du grand public à partir des millions de publications quotidiennes sur le web social : tweets, billets de blogs, messages sur les forums ou encore commentaires de la presse en ligne. Ces données massivement disponibles sont ainsi investies par des acteurs et des instruments extrêmement variés pour mesurer aussi bien la réputation des grandes marques et entreprises, que les réactions à une campagne publicitaire ou un débat télévisé, ou encore des pratiques de consommation émergentes ; tous ont en commun de s’intéresser pour cela aux opinions non sollicitées des internautes. Cette démarche rencontre par ailleurs un succès considérable depuis plusieurs années : en 2015, soit dix ans après la création des premières entreprises dans ce domaine, l’industrie des logiciels de social media analysis générait 2,2 milliards de dollars de chiffre d’affaires selon le cabinet Markets and Markets, qui prévoit par ailleurs la croissance de ce marché jusqu’à 17,9 milliards de dollars en 2019.À distance du positivisme qui entoure ces technologies comme d’une critique constructiviste extérieure à son objet, cette thèse cherche à décrire l’émergence de médiations d’un nouveau type qui se saisissent des traces conversationnelles du web social pour la mesure de l’opinion, et renouvellent ainsi le contenu épistémologique et politique de cette catégorie. Partant de l’hypothèse d’une pluralité des formes de l’opinion et des dispositifs qui la mesurent, nous suivons ainsi un ensemble extrêmement varié de modélisations, construites par des start-ups et entreprises innovantes. Nous nous intéressons ainsi dans un premier temps les tentatives de redéfinition de la notion de représentativité par l’échantillonnage de publics mobilisés et influents. Dans un second temps, nous étudions le modèle qui semble l’emporter sur ce marché, fondé sur des logiciels visant l’indexation exhaustive et continue des traces de la conversation en ligne. Mesurant l’opinion comme un flux continu d’événements singuliers, ces instruments rompent définitivement avec l’idée de représentativité et réactualisent une grammaire de l’opinion comme activité collective et discursive, attentive aux dynamiques médiatiques et relationnelles de la discussion en ligne. Ce régime indiciel de connaissance des opinions délaisse donc la quantification des majorités et des minorités pour la mesure des mobilisations et des mouvements de l’opinion"Know what people think." This slogan, posted on the homepage of the British company Brandwatch website, contains the promise of the new industry associated with the study of online opinion: know what people think, finally, without even having to ask. Indeed, since the mid-2000s, a group of agencies, startups and software companies offers to know the opinion from millions of daily publications on the social web: tweets, blog posts or messages on forums. These massively available data are invested by extremely diverse actors and instruments, to measure brand reputation, reactions to an advertising campaign or a televised debate, or emerging consumer practices. To this purpose, all have in common an interest for unsolicited opinions of Internet users. This approach met considerable success in recent years: in 2015, ten years after the creation of the first companies in this area of social media software industry analysis generated $ 2.2 billion in revenue by the firm markets and markets, which also provides for the growth of this market to $ 17.9 billion in 2019.Taking distance with both positivism, which surrounds these technologies, and with an external and critical constructivism, this thesis seeks to describe the emergence of a new type of mediation that captures conversational traces from the social web for measuring opinion, and thus renews the epistemological and political content of this category. Assuming the plurality of the instruments and regimes that measure opinion, we follow a very diverse set of models built by start-ups and innovative companies. We first analyze some attempts made by them to redefine the concept of representative sampling, based on the selection of mobilized and influential publics. Secondly, we study the model that seems to prevail in this market, based on software seeking a comprehensive and continuous indexing of the online conversation. Measuring the opinion as a continuous flow of singular events, these instruments definitively break with the idea of representativeness and reactualize a conception of opinion as collective and discursive activity, focused on the relational dynamics of the online discussion. This regime thus abandons the quantification of majorities and minorities, to concentrate on the mobilizations and movements of online opinion

The modern web has evolved into a highly capable software platform, which enables near-native performance, while offering installation-free cross-platform applications with a uniform user base and rapid update deployment. SVG, WebGL, and HTML5 Canvas, along with various higher-level JavaScript frameworks allow web applications to drive both 2D and 3D visualization. These technologies allow developing novel visualization applications, which can be applied in the communication domain to geospatially map service quality, and to provide tools research and education in wireless communication. We present two such web applications GeoSpy and CORNET3D.
GeoSpy provides 2D and 3D visualization of geospatial data on the web. The application is primarily focused on leveraging 3D portrayals to increase the number of broadband Quality of Service (QoS) metrics, which can be attached to a single point on a map. Additionally, GeoSpy has proven to be a flexible visualization platform by giving the user a high level of customization over HTTP API data. This allows GeoSpy to venture beyond broadband mapping, and provide 3D portrayals of any well-formatted geospatial JSON API.
Research of Software Defined Radio (SDR) and Dynamic Spectrum Access (DSA) can be used to significantly improve the wireless QoS. CORNET3D provides a 3D view of the Virginia Tech CORNET SDR testbed with information on which nodes and radios are operational. The application can also display 2D and 3D plots of the spectrum, which is sensed by the radios in real time. The data is sent to the client over a WebSocket connection to enable low latency, compared to conventional HTTP. CORNET3D can teach students about strategies for optimal use of spectrum resources through a game---"by providing them with real-time scoring based on their choices for radio transmission parameters. CORNET3D has demonstrated that the not only can web applications provide rich portrayals of real-time sensor data, but can also serve as a 3D "serious game" platform.Master of Science

In Web service composition, service discovery and combining suitable services through determination of interoperability among different services are important operations. Utilizing semantics improves the quality and facilitates automation of these operations. There are several previous approaches for semantic service discovery and service matching. In this work, we exploit and extend these semantic approaches in order to make Web service composition process more facilitated, less error prone and more automated. This work includes a service discovery and service interoperability checking technique which extends the previous semantic matching approaches. In addition to this, as a guidance system for the user, a new semantic domain model is proposed that captures semantic relations between concepts in various ontologies.

The open data movement has resulted in many datasets on the web to be freely available for anyone to freely access, use, modify and share for any purpose (subject, at most, to requirements that preserve provenance and openness). The Linked Open Data (LOD) cloud is an example of such an open data repository of attribute data in the form of billions of Resource Description Framework triples on the Web. Visualising such open data in thematic maps provides a powerful spatial analysis tool for planning and decision-making. In this research, several styles of creating web thematic maps by integrating the attributes from the LOD cloud with geometry in a spatial database server were investigated and evaluated. Requirements for a specialised geospatial web service that combines linked data with geospatial data to create thematic maps were specified. Standard technologies were used, motivated by the widespread deployment of standardised web map services in the geospatial community and the widespread publication of alphanumeric data (by statistical agencies) in the LOD cloud. A specialisation of an Open Geospatial Consortium Web Map Service (WMS) that creates web thematic maps by integrating alphanumeric linked data from the LOD cloud with geometry in a spatial database server was conceptualised. Three integration styles (referred to as design options) for this specialised web service were designed and implemented. The first style integrates linked data with spatial data by an importer. The second and third styles use a middleware and extension of a spatial database server respectively to integrate linked data with spatial data. In each of the three styles, attributes are retrieved from the LOD cloud through semantic queries and only the results of the semantic query are visualised on the thematic map. In this way, the benefits of semantic queries are exploited in the Semantic Web itself and the WMS mapping capabilities are used to visualise the semantic query results on a thematic map by integrating these with geospatial data. The three integration styles are critically evaluated against the specified requirements. This research contributes to understanding the pros and cons of incorporating semantic (linked) data models into standard geospatial web service models to create cartographic products (web thematic maps). This research contributes to bridging the gap between linked data and web thematic mapping.Thesis (PhD)--University of Pretoria, 2015.

Today a lot of libraries, tools and techniques exist to create visual appealing renders for the web. In this thesis, a prototype for visualizing baseboards in the web browser was developed. The prototype demonstrates how certain libraries and techniques were used in order to achieve a generalized, appealing and realistic visualization of the baseboards in a 3D-visualization. This paper also covers why certain libraries and techniques were used for this prototype. The resulting prototype, use Three.js and takes advantage of PBR, different mapping methods and lighting sources that can be changed during runtime through a GUI. To get results on different aspects, such as the visual appeal, how realistic, and what lighting sources worked best for the prototype, a web-survey was sent out and the results evaluated. The evaluation showed that the usage of PBR, a roughness-metalness workflow, environment mapping, physical correct lighting and a point light solution in Three.js all made a good job in creating an appealing, generalized and realistic visualization tool for the web.

Full textAbstract:
Although proprietary and free web map applications have become an important part of daily life, individual map styling has been neglected for a fairly long time. With the latest possibilities of custom adjustment provided by many services and some interesting artistic experiments, this is about to change. In the context of artistic cartography and custom map styling, this work explores the possibilities of employing an automated process for the generation of WMTS compatible map tiles with an artistic styling. Web mapping standards and techniques of non-photorealistic rendering (NPR) are considered as well as traditional cartographic representations. Furthermore, existing vector- and raster-based processes are analyzed including an interactive workflow with the open-source image editing software GIMP, which is examined with respect to its drawing capabilities. Based on this, a concept for an automated rendering process is developed and influencing factors along with input parameters are discussed. An experimental automated processing is implemented using GIMP and its Python scripting interface to create single maps and seamless map tiles for the use in a WMTS application. Different drawing techniques of GIMP, such as brushes, dynamics and masks are applied during the rendering process. Geodata is taken from the freely available OpenStreetMap project and it is stored in a geodatabase. Furthermore, the GIS capabilities of the database are used to implement custom query procedures for the creation of seamless tiles, feature simplification and generalization that makes a preprocessing of the data unnecessary. Additionally randomization methods for the estrangement and abstraction of the SVG vector graphics geometry to emulate a hand-drawn appearance are created based on non-photorealistic rendering techniques. As a result, various rendering and abstraction processes are evaluated and discussed regarding their contribution to an artistic appearance. Map tiles are created using these stylings which are WMTS compatible and can be presented in a web mapping application.

While semantic web data is machine-understandable and well suited for advanced filtering, in its raw representation it is not conveniently understandable to humans. Therefore, visualization is needed. A core challenge when visualizing the structured but heterogeneous data turned out to be a flexible mapping to Visual Variables. This work deals with a highly flexible, semi-automatic solution with a maximum support of the visualization process, reducing the mapping possibilities to a useful subset. The basis for this is knowledge, concerning metrics and structure of the data on the one hand and available visualization structures, platforms and common graphical facts on the other hand — provided by a novel basic visualization ontology. A declarative, platform-independent mapping vocabulary and a framework was developed, utilizing current standards from the semantic web and the Model-Driven Architecture (MDA)Während Semantic-Web-Daten maschinenverstehbar und hervorragend filterbar sind, sind sie — in ihrer Rohform — nicht leicht von Menschen verstehbar. Eine Visualisierung der Daten ist deshalb notwendig. Die Kernherausforderung dabei ist eine flexible Abbildung der strukturierten aber heterogenen Daten auf Visuelle Variablen. Diese Arbeit beschreibt eine hochflexible halbautomatische Lösung bei maximaler Unterstützung des Visualisierungsprozesses, welcher die Abbildungsmöglichkeiten, aus denen der Nutzer zu wählen hat, auf eine sinnvolle Teilmenge reduziert. Die Grundlage dafür sind einerseits Metriken und das Wissen über die Struktur der Daten und andererseits das Wissen über verfügbare Visualisierungsstrukturen, -plattformen und bekannte grafische Fakten, welche durch eine neuentwickelte Visualisierungsontologie bereitgestellt werden. Basierend auf Standards des Semantic Webs und der Model-getriebenen Architektur, wurde desweiteren ein deklaratives, plattformunabhängiges Visualisierungsvokabular und -framework entwickelt

In this work, we propose a new way to ``convert'' information, we propose a mapping algorithm of semantic information based on the context of the information in order to redefine the framework where this paradigm merges with multiple techniques.

L'adoption large du Web afin d'acceder a des informations distribuees necessite l'interoperabilite des systemes qui gerent ces informations. Des solutions et reflexions comme le Web Semantique facilitent la localisation et l'integration des donnees d'une maniere plus intelligente par l'intermediaire des ontologies. Il offre une vision plus semantique et comprehensible du web. Pourtant, il souleve un certain nombre de defis de recherche. Un des principaux defis est de comparer et aligner les differentes ontologies qui apparaissent dans des taches d'integration. Le principal objectif de cette these est de proposer une approche d'alignement pour identifier les liens de correspondance entre des ontologies. Notre approche combine les techniques et les methodes d'appariement linguistiques, syntaxiques, structurelles ou encore semantiques (basees sur les instances). Elle se compose de deux phases principales : la phase d'enrichissement semantique des ontologies a comparer et la phase d'alignement ou de mapping. La phase d'enrichissement est basee sur l'analyse des informations que les ontologies developpent (des ressources web, des donnees, des documents, etc.) et qui sont associes aux concepts de l'ontologie. Notre intuition est que ces informations ainsi que les relations qui peuvent exister entre elles participent a l'enrichissement semantique entre les concepts. A l'issue de la phase d'enrichissement, une ontologie contient plus de relations semantiques entre les concepts qui seront exploitees dans la deuxieme phase. La phase de mapping prend deux ontologies enrichies et calcule la similarite entre les couples de concepts. Un processus de filtrage nous permet de reduire automatiquement le nombre de fausses relations. La validation des correspondances est un processus interactif direct (avec un expert) ou indirect (en mesurant le degre de satisfaction de l'utilisateur). Notre approche a donne lieu a un systeme de mapping appele ROMIE (Resource based Ontology Mapping within an Interactive and Extensible environment). Il a ete experimente et evalue dans deux differentes applications : une application biomedicale et une application dans le domaine de l'apprentissage enrichi par les technologies (ou e-learning).

This thesis covers the systematic mapping of established public Application Programming Interface (API)s that are employing the Artificial Intelligence (AI) technology. This due to the fact that the problem has been the lack of systematic maps of AI APIs in the present time, therefore this thesis has the purpose of increasing the insight in the area by creating the mapping study. The goal is to provide both a basis for research and to aid the general developer which uses the AI APIs. The systematic mapping of the AI APIs will be conducted by examining the information of the APIs and iterations classifying the AI APIs into categories and presented in tables. The analysis and discussion of the study was made based on the results from the study, namely the phases, the iterations, the result tables and the final systematic map. Additionally, an analysis was made on the validity threats of the study. The evaluation of each API in this study was done in cycles, by categorizing each AI API into a category that is included in the final result, which is a systematic map. The result has been proven to be useful for the target group of this study, the researchers and developers, by aiding them in finding the right API for them to use in their work. Therefore, this work will help future developers and researchers due to the fact that the thesis is providing relevant information in the development phases of employing AI in the web interfaces at the present time.Detta examensarbete omfattar en systematisk kartläggning av etablerade publika API:er som använder sig utav AI- teknik. Eftersom bristen på systematiska kartor över AI API:er varit stor, har detta examensarbete syfte att öka insikten i området genom att skapa denna kartläggningsstudie. Målet med den systematiska kartläggningen är att bygga en grund för framtida forskning inom detta område, samt förenkla processen av att hitta AI API:erna för den allmänna utvecklaren som använder dessa. Den systematiska kartläggningen av AI API:er kommer att genomföras genom att undersöka tillgänglig dokumentation och information om API:erna. Dessutom klassificerades AI API:erna i kategorier, och presenterades sedan i tabeller. Analysen och diskussionen av studien gjordes baserat på resultaten från studien, nämligen faserna och iterationerna där AI API:erna kategoriseras, samt på resultat tabellerna och den slutliga systematiska kartan på AI API:erna. Dessutom gjordes en analys av hoten mot studiens giltighet. Utvärderingen av varje API i denna studie gjordes i cykler genom att kategorisera varje AI API i en kategori som sedan inkluderades i resultatet vilket är en systematiska karta. Resultatet från detta examensarbete har visat sig vara användbar för målgruppen, forskare och utvecklare, då det hjälper målgruppen att hitta rätt API att använda i arbetet.

Full textAbstract:
Dans cette thèse, nous présentons des approches d'adaptation d'un processus d'alignement aux caractéristiques des ontologies alignées, qu'il s'agisse de caractéristiques quantitatives telles que leur volume ou de caractéristiques particulières liées par exemple à la façon dont les labels des concepts sont construits. Concernant les caractéristiques quantitatives, nous proposons deux méthodes de partitionnement d'ontologies qui permettent l'alignement des ontologies très volumineuses. Ces deux méthodes génèrent, en entrée du processus d'alignement, des sous ensembles de taille raisonnable des deux ontologies à aligner en prenant en compte dès le départ l'objectif d'alignement dans le processus de partitionnement.Concernant les caractéristiques particulières des ontologies alignées, nous présentons l'environnement TaxoMap Framework qui permet la spécification de traitements de raffinement à partir de primitives prédéfinies. Nous proposons un langage de patrons MPL (the Mapping Pattern Language) que nous utilisons pour spécifier les traitements de raffinement.En plus des approches d'adaptation aux caractéristiques des ontologies alignées, nous présentons des approches de réutilisation des résultats d'alignement pour l'ingénierie ontologique. Nous nous focalisons plus particulièrement sur l'utilisation de l'alignement pour l'enrichissement d'ontologies. Nous étudions l'apport des techniques d'alignement pour l'enrichissement et l'impact des caractéristiques de la ressource externe utilisée comme source d'enrichissement. Enfin, nous présentons la façon dont l'environnement TaxoMap Framework a été implémenté et les expérimentations réalisées : des tests sur le module d'alignement TaxoMap, sur l'approche de raffinement de mappings, sur les méthodes de partitionnement d'ontologies de très grande taille et sur l'approche d'enrichissement d'ontologies.
