Full textAbstract:
Web development is receiving increasing attention among all kinds and sizes of companies. Web presentation has become a hygiene factor for companies nowadays. Fortunately, nowadays web developers can choose from a great number of ready-made technologies instead of developing everything from scratch. However, web development technologies have evolved much in the past 20 years. Due to the increased complexity and diversity of the alternatives, it is getting more and more difficult for companies to make an overall good choice of technologies, especially small and medium-sized enterprises (SMEs) that usually do not have resources to make a thorough research before choosing. This thesis creates WeTS - Web Technology Stack Guidelines, which contains three parts: process, algorithm and software quality characteristics. By following WeTS, inexperienced web developers, especially in SMEs, can select web technology stacks in an optimal way. Meanwhile, WeTS could be used for experienced practitioners and researchers as a reference to have an overview about modern web development technologies. Based on WeTS Guidelines, this thesis evaluated a number of technology stacks. Then a case study was performed with a startup company named Sqore. By comparing WeTS with Sqore’s technology selection process step by step, this thesis evaluated WeTS Guidelines.

Full textAbstract:
Web applications are collections of files for the purpose of responding to user requests in client-server mode over the World Wide Web. Most web applications have a connection to one or more databases for storing and delivering data as required by user requests. Some include a web server extension. There are a number of such systems, each belonging to a set of archetypes. Important factors in selecting a web application include conformance to principles of software engineering, ability to enforce application-level security, and resource conservation or high performance. Existing experimental studies do not provide the required data, owing to variations in configuration, aggregated, statistically mixed workloads, and lack of numerical performance criteria for the application alone. This research gained important insights from the application of scientific methods and numerical, objective criteria to the comparison of web applications. This project conducted architectural analyses, security tests and performance measurements of selected archetypes. This work assessed state saving, separation of concerns, security and performance with standardized tests administered in an invariant environment, i.e., host hardware, operating system, web server and database server. Architectural analysis was applied to state maintenance and separation of concerns. Interactive simulations tested abilities of archetypes to enforce security and to protect themselves from hacker attacks. Automated load tests measured resources consumed and application latency as a function of HTML request traffic. HTML page requests consisted of a standard set of queries against the same dataset. A load test application was developed to manage the testing and data-recording automatically. Results consist of rankings of web application archetypes according to a metric developed for this purpose. Supporting data consist of graphs of latency vs. time and page request traffic vs. resources consumed. Results show the capability of archetypes to enforce security, maintain data integrity, conserve server resources, and to make timely and efficient delivery of client-requested data

Web 2.0, the ultimate platform for tacit based knowledge work has finally arrived. User driven, collaborative platform based tools including wikis, web mash-ups, discussion boards, linkage based search engines, and tagging have the potential to vastly change how information is managed and how knowledge work is captured. This thesis investigates how the new paradigms and tools of Web 2.0 can be applied to the Pharmaceutical Industry and assist with information management at The Novartis Institute for BioMedical Research (NIBR). Applying Web 2.0 tools to NIBR's chemical compounds, targets, assays, people, and projects in a well thought out framework has the potential to yield tremendous productivity improvements in the drug discovery process. Effectively harnessing the collective intelligence of thousands of scientists within Novartis's worldwide research network will enable a paradigm shift. A large, extremely knowledgeable user community can more effectively annotate metadata, hyperlink to important content, establish tags, and collectively author content. Such activities will not only improve the search ability of information but also allow important scientific connections to emerge linking biology to chemistry and furthering Novartis's understanding of disease.

McElhiney, Patrick R. "Scalable Web Service Development with Amazon Web Services." Thesis, University of New Hampshire, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10931435.
Full textAbstract:
The objective of this thesis was to explore the topic of scalable web development, and it answered the question, “How do you scale a website to handle more traffic at peak times without wasting resources?” This is important research to any web company that has issues with rising costs as demand for their website increases. It would be wise for every online business to be prepared for more web traffic, before it occurs, without spending the budget of a multi-million user web company in low traffic periods. The last thing you want is an error as your customer base starts to arrive, giving them a bad experience for their first impressions, which would result in lost revenue.
Scalable software development architectures, including microservices, big data, and Kubernetes were studied, in addition to similar web service companies including Facebook, Twitter, and Match.com. A scalable architecture was designed for a social media web service, MeAndYou, using the big data configuration with a shared Aurora database, which was configured using an auto-scaling group attached to a load balancer in Amazon Web Services (AWS). It was tested using a custom threaded Selenium-based Python script that applied simulated user load to the servers. As the load was applied, AWS added more Elastic Compute Cloud (EC2) instances running a virtual disk image of the web server. After the load was removed, the instances were terminated automatically by AWS to save costs.
Countless steps were taken to make the web service bigger and more scalable than it originally was, before testing, including adding more fields to user profiles, adding more search types, and separating the layers of code into different Hypertext Preprocessor (PHP) files in the front-end. A version control system was configured on the servers using GitHub and rsync. The systems architecture designed suggests the Match Engine should use a stream processing message queue, which would allow the system to factor searches one at a time as they are created, with horizontal scaling capabilities, rather than grabbing the entire database and storing it in memory. The backend Match Engine was also tested for accuracy using Structured Query Language (SQL) injection, which determined how the match algorithm should be improved in the future.

Full textAbstract:
The vision of the Semantic Web aims at enhancing today's Web in order to provide a more efficient and reliable environment for both providers and consumers of Web resources (i.e. information and services). To deploy the Semantic Web, various technologies have been developed, such as machine understandable description languages, language parsers, goal matchers, and resource composition algorithms. Since the Semantic Web is just emerging, each technology tends to make assumptions about different aspects of the Semantic Web's architecture and use, such as the kind of applications that will be deployed, the resource descriptions, the consumers' and providers' requirements, and the existence and capabilities of other technologies. In order to ensure the deployment of a robust and useful Semantic Web and the applications that will rely on it, several aspects of the technologies must be investigated, such as whether the assumptions made are reasonable, whether the existing technologies allow construction of a usable Semantic Web, and the systematic identification of which technology to use when designing new applications. In this thesis we provide a means of investigating these aspects for service discovery, which is a critical task in the context of the Semantic Web. We propose a simulation and evaluation platform for evaluating current and future Semantic Web technology with different resource sets and consumer and provider requirements. For this purpose we provide a model to represent the Semantic Web, a model of the evaluation platform, an implementation of the evaluation platform as a multi-agent system, and an illustrative use of the platform to evaluate some service discovery technology in a travel scenario. The implementation of the platform shows the feasibility of our evaluation approach. We show how the platform provides a controlled setting to support the systematic identification of bottlenecks and other challenges for new Semantic Web applications. Finally, the evaluation shows that the platform can be used to assess technology with respect to both hardware issues such as the kind and number of computers involved in a discovery scenario, and other issues such as the evaluation of the quality of the service discovery result.

Full textAbstract:
In this report, we investigate how the methods developed for using in
Semantic Web technology could be used in capturing, modeling, developing, checking, and validating of requirements specifications.
Requirements specification is a complex and time-consuming process. The goal is to describe exactly what the user wants and needs before the next phase of the software development cycle will be started. Any failure and mistake in requirements specification is very expensive because it causes the development of software parts that are not compatible with the real needs of the user and must be reworked later. When the analysis phase of a project starts, analysts have to discuss the problem to be solved with the customer (users, domain experts) and then write the requirements found in form of a textual description. This is a form the customer can understand. However, any textual description of requirements can be (and usually is) incorrect, incomplete, ambiguous, and inconsistent. Later on, the analyst specifies a UML model based on the requirements description written by himself before. However, users and domain experts cannot validate the UML model as most of them do not understand (semi-)formal languages such as UML.
It is well-known that the most expensive failures in software projects have their roots in requirements specifications. Misunderstanding between analysts, experts, users, and customers (stakeholders) is very common and brings projects over budget. The goal of this investigation is to do some (at least partial) checking and validation of the UML model using a predefined domain-specific ontology in OWL, and to process some checking using the assertions in descriptive logic.
As we described in our previous papers, we have implemented a tool obtaining a modul (a computer linguistic component) that can generate a text of requirements description using information from UML models, so that the stakeholders can read it and decide whether the analyst's understanding is right or how different it is from their own one. We argue that the feedback caused by the UML model checking (by ontologies and OWL DL reasoning) can have an important impact on the quality of the outgoing requirements.
This report contains a description and explanation of methods developed and used in Semantic Web Technology and a proposed concept for their use in requirements specification. It has been written during my sabbatical in Oviedo and it should serve as a starting point for theses of our students who will implement ideas described here and run some experiments concerning the efficiency of the proposed method.

Everything is connected to everything. El Aleph (1945), by Jorge Luis Borges[1] This thesis addresses the need to simplify and streamline web service network infrastructure and to identify business models that best leverage Web services technology and industry dynamics to generate positive business results. Web services have evolved from the simple page-display protocol of their origin and now reach beyond the links that simply updated web data dynamically from corporate databases, to where systems can automatically transact. These Web services represent a series of network business technology standards and capabilities that irrevocably change the way in which businesses will do business. In fact, every business today is a networked business and has opportunities to grow using Web services. This study focuses on the implementation challenges in the financial services market, specifically the On Line Transaction Processing (OLTP) sector where legacy mainframes interface with multiple tiers of distribution through proprietary EDI links. The OLTP industry operates under stringent regulatory requirements for availability and audit-ability of not only who performed what transaction, but who had access to the information about the information. In this environment organizational demands on network infrastructure including hardware, software and personnel are changing radically, while concurrently Information Technology (IT) budgets are under pressure. The strategic choices for deploying web services in this environment may contain lessons for other industries where cost effective large scale processing, high availability, security, manageability and Intellectual Property Rights (IPR) are paramount concerns. In this paper we use a systems dynamics model to simulate the impact of market changes on the adoption of innovative technologies and their commoditization on the industry value chain, with the aim of identifying business models and network topologies which best support the growth of an Open Systems network business. From the results of the simulation we will derive strategic recommendations for networked business models and web services integration strategies to meet Line Of Business (LOB) objectives.

Full textAbstract:
Digital divisions are getting smaller in Sweden which makes the range of users wider than ever before. This results in higher expectations and requirements on web in order to be sufficient for everyone. This study investigates how web agencies work with web accessibility, why some do not work with it and solutions making daily operations more efficient. This is a qualitative study with an inductive approach, where semi-structured interviews were used to gather empirical data. Six web agencies in Jönköping took part of the study through interviews. In order to analyse the empirical data we used thematic analysis. No unknown methods or techniques were discovered along the study. There were surprisingly few agencies that worked with accessibility at all of those who took part in the study. Some of them more than others, but overall it was low prioritized. Lack of knowledge within the subject became the main reason for not develop for accessibility. An immature and non-standardized industry might be the explanation behind that. Not surprisingly, resources in form of economy is also a reason. It turns out to be hard for agencies to motivate customers to pay for accessibility. However, the motivation process with customers is rarely supported by enough knowledge and leads therefore to insufficient arguments, which does not motivate customers enough to pay for it. Further on, include web accessibility as a given part of CSR plans on both agencies side, but also motivating it for customers. The importance of a mature dialog about it is crucial for survival of accessibility. All parties of a development process should take their responsibility. Everyone can and should participate in the journey towards a more equal society.

Mustafa, Faisal. "Dynamic web services composition." Thesis, University of Huddersfield, 2014. http://eprints.hud.ac.uk/id/eprint/24698/.
Full textAbstract:
Emerging web services technology has introduced the concept of autonomic interoperability and portability between services. The number of online services has increased dramatically with many duplicating similar functionality and results. Composing online services to solve user needs is a growing area of research. This entails designing systems which can discover participating services and integrate these according to the end user requirements. This thesis proposes a Dynamic Web Services Composition (DWSC) process that is based upon consideration of previously successful attempts in this area, in particular utilizing AI-planning based solutions. It proposes a unique approach for service selection and dynamic web service composition by exploring the possibility of semantic web usability and its limitations. It also proposes a design architecture called Optimal Synthesis Plan Generation framework (OSPG), which supports the composition process through the evaluation of all available solutions (including all participating single and composite services). OSPG is designed to take into account user preferences, which supports optimality and robustness of the output plan. The implementation of OSPG will be con�gured and tested via division of search criteria in di�erent modes thereby locating the best plan for the user. The services composition and discovery-based model is evaluated via considering a range of criteria, such as scope, correctness, scalability and versatility metrics.

With AMS comes great possibilities for increased energy efficiency, but to achieve its full potential, the end users must be provided with the necessary means of monitoring and controlling their consumption. This thesis describes the process of developing a web application prototype meant to serve such a purpose. It explains the various architectural and technological decisions that support the prototype, and it elaborates on how data from the users’ smart meters can be synthesized with price information to help users see the economic effect of their current consumption pattern. A working prototype has been developed and security- and performance tests have been carried out to mitigate bottlenecks and prevent security breaches. Observations during the pilot project have shown promising trends and it is hoped that this thesis will inspire further innovation in the field of smart energy solutions.

There are many types of computerized training systems available today ranging from text-based "quizzers" to interactive multimedia "edutainment". However, each system is proprietary to the platform for which the binary executable is compiled. Additionally, when the information in the training material changes, a new copy must be created, distributed and installed before it is available to the end user. This thesis explores the use of the Java programming language as a fundamental element in the creation of interactive courseware deployable through the World Wide Web. Java is used to add interactive, executable content to Web pages in the form of simulations and complex demonstrations of educational concepts. Complete online materials were developed in support of the initial offering of CS2973, a Java programming course. Following that success, a prototype interactive online exam system, using a Java applet and file server, was developed. This prototype foreshadows a complete virtual classroom environment supported by a Courseware Creation Interface. Both of these have the distinct advantage of being cross-plafform by virtue of being created in the Java programming language, thus usable on a majority of operating systems and platforms through Java-enhanced Web browsers

Full textAbstract:
Advancements in web technology such as the integration of operating platforms, the application of mobile applets and connectivity with databases into an encompassing web environment has promoted the development of complex web-based systems for enterprise computing. In this integration the inherent security flaws and associated problems of these technological advancements are also brought together under this web environment. These flaws, when exploited, could lead to system compromises of various kinds including stealing of security sensitive information, system take-over fabrication of fake electronic documents and illegal alteration to web sites contents. Therefore, the successful, prompt and appropriate responses of these complex web-based systems to security threats and breaches, such as in the cases of document tampering and misrepresentation from illegal users, are imperative in promoting the user's willingness and confidence when interacting with these systems. Accordingly, this has become one of the major concerns in development, management and operation of web-based systems. This thesis also studies the authentication of dynamic web contents through the application of a one-time digital signature. To this effect, relevant concepts and possible approaches have been discussed. Authentication and verification of dynamic contents, efficiently in the web environment, is suggested as a separate research area and as a direction for future work.Master of Science (Honours) Computing

Incoming classes decry housing for its poor communication and lack of information. Housing counselors, ever aware of customer satisfaction, spend too much time transacting routine information rather than helping families solve unique problems. This study examines how world Wide Web technology can widen the bottleneck of poor communications between counselor and customer so as to facilitate both information transactions and problem solving. To provide an analysis of the effectiveness in meeting housing customer needs, this study gauges housing customer satisfaction and determines those elements that customers believe constitute A Great Housing Office. An employee survey, a counselor focus group and archival research further demonstrate the dichotomy between where effort is expended and where it is needed. Customer communication and information expectations cannot be met under the current system. Analysis of qualitative and quantitative data demonstrate that the NPS Housing Welcome Center can overcome its information bottleneck by exploiting the technological advances of the World Wide Web and becoming a hub of information resources.

Approved for public release; distribution is unlimited.Peace Operations include Peace Making, Peace Building, and Peace Support. Although information-sharing systems may exist within individual organizations, to date no interoperable information regime exists that can link all players who participate in providing aid during a Complex Humanitarian Emergency. Effective information sharing between civilian and military organizations is needed to enhance operational efficiencies, therefore saving lives, resources, and promoting rapid recuperation and reconstruction. An off-the-shelf collaborative software package with a common architecture and common templates, standard protocols, and centralized database might initially serve as a collaboration platform. Extensible Markup Language (XML,) XML-based languages, and Resource Description Framework (RDF) are important technologies that must be utilized extensively to enable this environment. Additionally, WebDAV (Web-based Distributed Authoring and Versioning) integration can provide an infrastructure for platform-neutral asynchronous collaborative authoring via the Internet. Internationalization (I18N) and localization (L10N) addresses differences in language requirements and local expectations that reflect our differences in cultures. Existing collaboration COTS architectures form a basis with which developers can integrate XML technologies. The "Ideal" collaborative environment must include asynchronous and synchronous collaboration capabilities, as well as capabilities that will enable users to rapidly locate personnel, organize and conduct virtual teams and meetings, provide information delivery to personnel, and provide sufficient security mechanisms.

Many firms and individuals have been publishing data and services on the Web. It is necessary to develop advanced technology facilitating the use of Web data and services and to understand what impacts on firms and individuals would be. This thesis, composed of three essays, aims to explore (1) what technology could be developed to facilitate using Web data and services, and (2) what theoretical mechanisms are driving the impact of using Web data and services. The first essay describes an advanced technology for using Web services and the other two essays present some theoretical mechanisms and empirical evidences about how consumers are influenced by the data published on commercial webpages. The first essay presents a classification of the data misinterpretation problems that may occur when composing Web services. After the problem scope is identified, it proposes an approach to automatic detection and reconciliation of data interpretation conflicts in Web services composition. To validate and evaluate the approach, the first essay describes a prototype and demonstrates the approach can significantly alleviate the reconciliation efforts for Web services composition. The second essay explores how herding and social media Word of Mouth (WOM) drive product sales when commercial websites disclose the sales data in real-time on the product pages and integrate with social-networking platforms (e.g., Facebook, Twitter). Using a panel data set consisting of about 500 deals from Groupon.com, the second essay shows both herding and Facebook-mediated WOM lead to additional product sales, whereas Twitter-mediated WOM has no significant impact on sales. More importantly, it documents that herding and Facebook-mediated WOM are complements in driving sales. Given the fact that many commercial websites integrate with social-networking platforms and the importance of social media endorsements, the third essay investigates if online review ratings would affect consumers' decisions of endorsing via Facebook and purchasing products. It builds a stylized Bayesian learning model and derives three hypotheses. The empirical findings largely support the hypotheses. In particular, the results show that a favorable valence of online reviews causes to increase consumers' social media endorsements and the estimated effect is greater when the variance in the review ratings is larger. Moreover, the findings reveal that consumers exhibit different behaviors when they consider endorsing versus purchasing products.

Full textAbstract:
In developing and constructing process models, a large amount of data is generated. This needs to be stored as information by providing context (e.g. description and units), such that it may be accessed and Understood by both human users and computer tools. To be useful, information sets must be chronicled by recording information such as by whom it was generated, when, and using what tool. Links should also be maintained between related sets of information to document the relationship. The World Wide Web (WWW) facilitates the provision of links between documents. It may, amongst other things, be thought of as a globally addressable file system. Accessed by a graphical tool, the browser, it can provide a common user interface to access and interact with documents across disparate operating systems. Documents on the WWW include hypertext links, which enable one document to link to another. This thesis describes an object-oriented system which makes use of the www to chronicle process model construction. The object-oriented paradigm has been used to provide a convenient mechanism for encapsulating data in a structured framework. As well as containing the object data, objects also contain information on who created the object, at what time, etc. This information may be used to generate a browsable history of object creation. Objects are stored as www documents, and may be created, viewed and manipulated using standard browsers. An application programmer's interface has been written which enables the information to be manipulated via Fortran programs. Objects have been developed for standard process engineering entities such as streams, mixtures, components, process topologys, etc. Once created, these may be used to generate simulation models in a variety of formats, e.g. ASPEN, spreadsheet model, etc. Conversely, process objects may be generated from ASPEN models. Four case studies have been included, showing various applications of the system. In conclusion, the www provides a suitable environment for implementing such a system, due to its ease of use, and the fact that it provides both a user interface and enables remote access to the system.

As a data provider, the service program publishes its Web API and implements the specified functions.
In the project reported by this thesis, we have implemented two Web mashup applications to enhance the Web site oystersentinel.org: the Perkinsus marinus model and the Oil Spill model. Each model overlay geospatial data from a local database on top of a coastal map from Google Maps. In addition, we have designed a Web-based data publishing service. In this experimental system, we illustrated a successful Web mashup interface that allows outside developers to access the data about the local oyster stock assessment.

Data management is vital to the running of any organisation, small and large alike. It has been proven time and again, that organisations with poor data management/administration will not survive in this competitive world. [Bro99] states that although technology is a key enabler of change, its main role is to be the servant, not the master. Therefore, there is a need for the research world to reconsider the role of data in computing. Enabling technologies should be used to utilise the most effective and efficient access to the data.

Full textAbstract:
Mobile web browsers of today have many of the same capabilities as their desktop counterparts. However, among the capabilities they lack is a way for web applications to interact with local devices. While today’s mobile phones commonly include GPS receivers and digital cameras, these local devices are currently not accessible from within the browser. The only means of utilizing these devices is by using standalone applications, but such applications lack the versatility of web browsers. If a mobile browser could utilize these local devices, then a mobile application could run within the browser, thus avoiding the need for specialized client software. This thesis suggests an approach for adding such capabilities to mobile browsers. In the proposed method, scripted access to local device functionality is facilitated by a local Java application. This application acts as a proxy server and allows the browser to call methods exposed by the local Java APIs. Both the benefits and some security concerns of this approach are examined. The benefits are further highlighted through two example web applications which utilize local devices.I dagens mobila webbläsare återfinns det mesta av funktionaliteten från webbläsare för datorer. Det som dock fortfarande saknas är möjligheten för webbapplikationer att komma åt lokala telefonfunktioner. Dagens mobiltelefoner är ofta utrustade med GPS-mottagare och digitalkameror, men dessa kan för närvarande ej nås från webbläsaren. Det enda sättet att utnyttja dessa inbyggda funktioner är genom separata applikationer, men sådana applikationer är inte lika mångsidiga som webbläsare. Om en mobil webbläsare kunde utnyttja de inbyggda funktionerna, så skulle en mobil applikation kunna köras i webbläsaren istället för att ha separat klientprogramvara. Det här examensarbetet föreslår ett sätt att ge denna möjlighet till mobila webbläsare. I den föreslagna metoden används en lokal Java-applikation för att ge tillgång till inbyggda funktioner via skript. Denna applikation fungerar som en proxy-server och låter webbläsaren anropa metoder exponerade av lokala Java-API. Både fördelar och några säkerhetsproblem med den här lösningen undersöks. Fördelarna visas ytterligare genom två exempel på webbapplikationer som utnyttjar inbyggda telefonfunktioner.

Introduction: If the emergence of the World Wide Web was the communications and business phenomenon of the 1990' s, then the Mobile Web is already poised to be the darling of the next phase of the personal communications evolution. Consumers are already bombarded with a panoply of mobile communications products and services: wireless telephony, cellular handset mini-browsers, short message services, text paging. Driven by either personal or business habits forged on the traditional Internet, the perception is that consumers are increasingly turning to technologies that enable continuous or ad hoc information access in mobile situations, such as driving in a car or walking down the street. These technologies are primarily viewed as complements to, and not replacements for, the traditional modes of information access. As the name would suggest, the addition of the term "Voice Web" to the lexicon suggests yet another mode of mobile information access: speech interaction. While many of the technologies that support general speech recognition applications are hardly new, the consumer is infrequently exposed to anything more substantial than the most trivial of interactions, e.g. "Press or say '1.'" The relative anonymity of speech-interactive applications, coupled with the intoxicating (if not gratuitous) use of the term "Web," has created the perception that a new era of information access is about to dawn on the mobile consumer landscape, e.g. The Kelsey Group forecasts that by the year 2005, 45 million users will propel the voice market to $12 billion annually, more than $5 billion of which will be generated by advertising and commerce.2 The concern is not whether such estimations or projections are merited, but that the uncritical acceptance of the patently ambiguous Voice Web overlooks the multiplicity of dynamic forces that will come to bear on the evolution of the voice market in general. -- How does the structure of the historically vertically-integrated speech industry affect the evolution of the market? -- How will applications be accessed, e.g. democratic web of sites or carrier-specific private network? -- Are all the necessary technology platforms, networks, and standards in place to support the desired vision of the voice market? -- Who owns the direct relationship with the consumer, and how does service pricing affect both the quantity and quality of applications? -- What are the trademark issues involved in providing access to audio content already on the Internet, i.e. does a voice service provider need CNN's permission to play audio files freely accessible on the CNN website? -- What limitations does the telephony voice user interface impose on the application space? -- Ultimately, will the applications being proposed provide significant value for the consumer., thereby creating sufficient demand to seed further development? Given the complex interplay of the technological, economic, regulatory, and even human factors suggested above, the realization of the Voice Web concept is certainly not assured. As the opening quote from Dr. Meisel suggests, the pre-existence of the speech and Internet industries should not lull the reader into assuming that these two worlds will naturally merge into a single coherent and intuitive service model. While recent standardization efforts indicate a desire to extend the Internet service framework to voice applications, there has been little critical analysis of whether these technological innovations are sufficient to the task; moreover, other market factors (e.g. economics) are accorded little consideration in light of their potential impact on the evolution of the industry. For firms individually and the industry collectively, the success of the Voice Web ultimately depends on the anticipation of and appreciation for these interdisciplinary factors. This paper represents an attempt at a framework for both enumerating and negotiating these complex interrelationships, for the purpose of answering the following question: "Will a Voice Web model naturally arise from existing industry structures and market forces?" or conversely, "What is required to ensure the realization of the Voice Web?"

Full textAbstract:
Today, one of the biggest challenges that E-management systems face is the explosive growth of operating data and to use this data to enhance services. Web usage mining has emerged as an important technique to provide useful management information from user's Web data. One of the areas where such information is needed is the Web-based academic digital libraries. A digital library (D-library) is an information resource system to store resources in digital format and provide access to users through the network. Academic libraries offer a huge amount of information resources, these information resources overwhelm students and makes it difficult for them to access to relevant information. Proposed solutions to alleviate this issue emphasize the need to build Web recommender systems that make it possible to offer each student with a list of resources that they would be interested in. Collaborative filtering is the most successful technique used to offer recommendations to users. Collaborative filtering provides recommendations according to the user relevance feedback that tells the system their preferences. Most recent work on D-library recommender systems uses explicit feedback. Explicit feedback requires students to rate resources which make the recommendation process not realistic because few students are willing to provide their interests explicitly. Thus, collaborative filtering suffers from “data sparsity” problem. In response to this problem, the study proposed a Web usage mining framework to alleviate the sparsity problem. The framework incorporates clustering mining technique and usage data in the recommendation process. Students perform different actions on D-library, in this study five different actions are identified, including printing, downloading, bookmarking, reading, and viewing the abstract. These actions provide the system with large quantities of implicit feedback data. The proposed framework also utilizes clustering data mining approach to reduce the sparsity problem. Furthermore, generating recommendations based on clusters produce better results because students belonging to the same cluster usually have similar interests. The proposed framework is divided into two main components: off-line and online components. The off-line component is comprised of two stages: data pre-processing and the derivation of student clusters. The online component is comprised of two stages: building student's profile and generating recommendations. The second stage consists of three steps, in the first step the target student profile is classified to the closest cluster profile using the cosine similarity measure. In the second phase, the Pearson correlation coefficient method is used to select the most similar students to the target student from the chosen cluster to serve as a source of prediction. Finally, a top-list of resources is presented. Using the Book-Crossing dataset the effectiveness of the proposed framework was evaluated based on sparsity level, and Mean Absolute Error (MAE) regarding accuracy. The proposed framework reduced the sparsity level between (0.07% and 26.71%) in the sub-matrices, whereas the sparsity level is between 99.79% and 78.81% using the proposed framework, and 99.86% (for the original matrix) before applying the proposed framework. The experimental results indicated that by using the proposed framework the performance is as much as 13.12% better than clustering-only explicit feedback data, and 21.14% better than the standard K Nearest Neighbours method. The overall results show that the proposed framework can alleviate the Sparsity problem resulting in improving the accuracy of the recommendations.

Full textAbstract:
Data discovery and data handling often presents serious challenges to organizations that manage huge archives of raster datasets such as those generated by satellite remote sensing. Satellite remote sensing produces a regular stream of raster datasets used in many applications including environmental and agricultural monitoring. This thesis presents a system architecture for the management of time-series GIS raster datasets. The architecture is then applied in a prototype implementation for a department that uses remote sensing data for agricultural monitoring. The architecture centres on three key components. The first is a metadatabase to hold metadata for the raster datasets, and an interface to manage the metadatabase and facilitate the search and discovery of raster metadata. The design of the metadatabase involved the examination of existing standards for geographic raster metadata and the determination of the metadata elements required for time-series raster data. The second component is an interactive tool for viewing the time-series raster data discovered via the metadatabase. The third component provides basic image analysis functionality typically required by users of time-series raster datasets. A prototype was implemented using open source software and following the Open Geospatial Consortium specifications for web map services (WMS) version 1.3.0. After implementation, an evaluation of the prototype was carried out by the target users from the RRSU (Regional Remote Sensing Unit) to assess the usability, the added value of the prototype and its impact on the work of the users. The evaluation showed that the prototype system was generally well received, since it allowed both the data managers and users of time-series datasets to save significant amounts of time in their work routines and it also offered some raster data analyses that are useful to a wider community of time-series raster data managers.

Full textAbstract:
In the current era of state-of-the-art cutting edge technologies, businesses and organisations are rushing to transform their trade into e-business. The opportunity to utilise e-business improves their chances of gaining a larger market share by maximizing product availability, reducing the day-to -day business activity processing time, and providing related services in a convenient and inexpensive way to their customers. However in this race, the e-business growth pendulum is only swinging one way, and it is easy to understand the reason for this by observing today's business market. Due to the current financial condition, small business organizations (e.g. local retail shops) cannot afford costly IT systems and the associated maintenance/administration costs, but despite these financial constraints they have an overriding need for computing facilities in order to survive and compete with larger competitors by expanding their businesses. In this research, Web 2.0 and SOA (Service Oriented Architecture) technology are used to provide a middleware collaboration model between data persistence logic and an operation's requests. This layer helps to overcome the hard-coded service mapping with interface and generic customized workflow problems. This research further provides a mediation platform for request brokers and a high level of abstraction by encapsulating the low level details of the system. These are the most vital requirements to provide a platform, which have the capability of customizing business logic and handle both generic and customized workflows and subsequently to help SMEs (Small- to Medium-sized Enterprises) to convert their businesses to e-business swiftly at minimal cost.

Research has shown that the use of technology in curriculum, and art classrooms in particular, can benefit students. This thesis outlines these benefits which include the potential for technology to make learning more personal, assist students in their future careers, and allow opportunity for collaboration. Still, several obstacles impede the full-fledged realization of that potential, often leading teachers to avoid or ignore technology in their pedagogical strategies. This thesis addresses these obstacles and provides practical and theoretical solutions. Once these obstacles are overcome, teachers will be better able to incorporate new technology in their lessons, such as social media, podcasts, open-source websites, and online programs. As an example of art teaching that uses technology, this thesis also provides a sample lesson plan for secondary students, incorporating elements of interactive Web technologies that have been recommended by art education scholars.

Aschoff, Rafael Roque. "A proactive adaptation framework for composite web services." Thesis, City University London, 2014. http://openaccess.city.ac.uk/13548/.
Full textAbstract:
Service orientation is a design paradigm consisting of a set of principles governed by a service-oriented architecture (SOA) to support the creation of software systems as a composition of interoperable services. The ability to effectively compose services is not a trivial task due to the dynamic nature of the execution environment of service compositions. In this context, dynamic service selection and composition is a critical requirement and one of the major research challenges for service-based systems. This research investigates the identification, detection and prediction of the need for adaptation as well as ways to autonomously reconfigure the service composition during its execution time in order to improve service reliability and conformance with systems requirements and policies. We propose a framework for proactive adaptation of service compositions that extends current approaches for dynamic service composition by proactively and individually identifying the need for adaptation for each parallel running instance of service composition while avoiding unnecessary changes and distributing load request among different service operations when necessary. Our framework has been tested and validated using different prototypes implemented in both simulated and real environments. The results were favourable with the research objectives and indicates a major gain in the use of the proposed proactive techniques in the execution and adaptation of web service compositions.

Full textAbstract:
This thesis describes the project “A new Web Server for sensors”. The project has created a demonstration web service that can receive data from sensors ( both fixed sensors and movable sensors) and distribute the received information in the form of web pages. These web pages can provide forms that enable the user to enter commands which are to be given to sensors. The aim of this thesis project was to design and evaluate web-based application which could utilize sensor data. In this project, we focused on two aspects: (1) web access to sensors and (2) the potentialmobility of sensors. The web server provides web server mediated access to the sensors. Additionally, this project examined how to integrate a sensor with a mobile device, such as a personal data appliance. The web server provides an easy acces smechanism to users who want to use and control sensors. Those users can flexibly us etheir web browser to access to sensors through our web server. Moreover, a sensor could move, for example because it is integrated with a personal data appliance. The mobility of sensors increases the sensing scope of sensors because the sensors are notfixed in position. Such sensors can sense the environment along the path that they are moved. To achieve the goals of this thesis project, we analyzed what are the basic parts and functions that should exist for sensors in the web server. Furthermore, the thesis analyzed how a sensor can be integrated with a personal data appliance, for instance,how to supply the power to sensor; and how to synchronize data between the sensor and personal data appliance. As a result of this project, a web server with some of the necessary functions was developed. An approach of how to integrate a sensor with a personal data appliance is specified in this thesis. The thesis begins with an analysis of some existing solutions. Their advantages were used to specify the requirements for our own solution. The thesis describes the design and implementation of this proposed solution. Next the thesis describes the testing and evaluation of this solution in the context of this project. The thesis ends with some conclusions and suggests future work.Denna avhandling beskriver projektet "En ny webbserver för sensorer". Projektet har skapat en tjänst demonstration nätet som kan ta emot data från sensorer (både fasta sensorer och rörliga sensorer) och distribuera fått information i form av webbsidor. Dessa webbsidor kan ge former som gör det möjligt för användaren attskriva in kommandon som ges till sensorer. Syftet med detta examensarbete var att designa och utvärdera webbaserad applikation som kan använda sensordata. I detta projekt har vi fokuserat på två aspekter: (1) webb tillgång till sensorer och (2) depotentiella rörlighet av sensorer. Webbservern ger Web Access Server förmedlas till sensorer. Dessutom undersökte detta projekt hur man kan integrera en sensor med en mobil enhet, t.ex. en personuppgifter apparat. Webbservern ger en enkel tillgång mekanism för användare som vill använda och styra sensorer. Dessa användare kanflexibelt använda sin webbläsare för att få tillgång till sensorer via vår webbserver. Dessutom kan en sensor röra sig, exempelvis genom att den är integrerad med en personuppgifter apparat. Rörligheten av sensorer ökar avkänning omfattningen av sensorer eftersom sensorerna inte är fasta på plats. Sådana sensorer kan känna miljön längs den väg som de flyttas. För att nå målen med denna avhandling projektet analyserade vi vad som är grundläggande delar och funktioner som bör finnas för sensorer i webbservern.Dessutom analyseras i avhandlingen hur en sensor kan integreras med en personuppgifterna apparat, till exempel, hur man levererar energi till sensorn, och hur man synkronisera data mellan sensorn och personuppgifter apparaten. Som ett resultatav detta projekt var en webbserver med några av de nödvändiga funktioner utvecklas.En strategi för hur man kan integrera en sensor med en personuppgifterna apparat som anges i denna avhandling. Avhandlingen inleds med en analys av några befintliga lösningar. Deras fördelar har använts för att specificera kraven för vår egen lösning. Avhandlingen beskriver utformningen och genomförandet av den föreslagna lösningen. Nästa avhandlingen beskriver testning och utvärdering av denna lösning i samband med detta projekt. Avhandlingen avslutas med några slutsatser och föreslår framtida arbete.

Web-based enterprise software - sometimes referred to as "Software as a Service" (SaaS) or "on demand software" - is a major wave of innovation that introduces a new technical and economic model to enterprise software. The defining characteristics of web-based enterprise software are: a fully web-based user interface, hosted application deployment, a SaaS-based business model, and the use of a service-oriented architecture for integration. This study analyzes a sample of 108 companies currently offering SaaS-based products. In total, 35 different application types and 20 different combinations of revenue models were counted. Apparently, the market is still in an experimental phase, and truly dominant designs haven't emerged yet. Gross margins for SaaS-oriented companies are lower than for traditional software product companies, but still attractive at around 85%. The entrepreneurial activity in the sector is significant. More than 50% of the companies in the sample were founded in or after 2002, and almost 30% in the last two years. Venture capital continues to be an important source of capital with 36% of the companies having received VC investment, but an equally large percentage of companies are boot-strapped, i.e. have no formal source of outside capital.
(cont.) The data about customer adoption of web-based enterprise software is not very clear. Most studies suggest that SaaS accounted for about 5% of the CRM market in 2006, with other application types below that level. In total, SaaS probably doesn't even account for 1% of the global software market. However, customer willingness to adopt SaaS is apparently rising very quickly, and specialized SaaS companies are experiencing rapid growth. From the data available, it can't be decided unambiguously if web-based enterprise software is a truly disruptive model or merely an incremental innovation. Most characteristics point to a new-market disruption, i.e. an innovation that will bring new functionality to current non-users of advanced enterprise software.

Web Services which are specific functionalities and can be combined to meet a particular user''s needs have become a mature technology in the past few years. However, the discovery and search mechanism provided by UDDI based on keyword matching may lead to an ambiguous answer. It is a challenge to target the suiting Web services precisely. Semantic Web technology provides another option for service matching. It enables a service profile to be described according to its functionalities in OWL, which is based on Description Logics. Recently, researchers are dedicated on studying Semantic Web technology as a primary tool for ontology-based Web Services searching and invocation. With help of precise semantics description, Web Services are able to be utilized automatically. Under such a Semantic Web search mechanism, Web Services profile and domain ontology are both described by Description Logics. However, potential users often do not have any knowledge about Description Logics. That creates a huge gap and critically imposes high entrance barriers for the user. Besides, ontology maintenance is another important issue for Semantic Web applications. Ontology maintenance is a time-consuming job. Ontology maintenance is usually controlled by a small group of people. But it has several drawbacks: (1) the addition can be time-consuming and lack of completion and (2) the ontology maintainer read the concept in the different manner from how potential user does. Accordingly, sometimes concepts become obsolete by the time they enter the ontology. In the long run, ontology maintenance cannot be ignored especially in such a Semantic Web application. In this thesis, we proposed: (1) an open system architecture to lower the entrance barriers of Semantic Web applications, (2) a practical approach to ontology maintenance, and (3) a new prototype system. The Traveller was implemented based on our ontology- based architecture and related methodologies. With the service composition and execution architecture, the user is able to find suiting Web Services, invoke services by defining BPEL4WS, and participate in collaborative ontology maintenance without knowing any Semantic languages.
