Abstract:
Representation of temporal and spatial information for the Semantic Web often involves qualitative defined information (i.e., information described using natural language terms such as “before” or “overlaps”) since precise dates or coordinates are not always available. This work proposes several temporal representations for time points and intervals and spatial topological representations in ontologies by means of OWL properties and reasoning rules in SWRL. All representations are fully compliant with existing Semantic Web standards and W3C recommendations. Although qualitative representations for temporal interval and point relations and spatial topological relations exist, this is the first work proposing representations combining qualitative and quantitative information for the Semantic Web. In addition to this, several existing and proposed approaches are compared using different reasoners and experimental results are presented in detail. The proposed approach is applied to topological relations (RCC5 and RCC8) supporting both qualitative and quantitative (i.e., using coordinates) spatial relations. Experimental results illustrate that reasoning performance differs greatly between different representations and reasoners. To the best of our knowledge, this is the first such experimental evaluation of both qualitative and quantitative Semantic Web temporal and spatial representations. In addition to the above, querying performance using SPARQL is evaluated. Evaluation results demonstrate that extracting qualitative relations from quantitative representations using reasoning rules and querying qualitative relations instead of directly querying quantitative representations increases performance at query time.

Abstract:
Recently, many approaches have been proposed to manage sensor data using semantic web technologies for effective heterogeneous data integration. However, our empirical observations revealed that these solutions primarily focused on semantic relationships and unfortunately paid less attention to spatio–temporal correlations. Most semantic approaches do not have spatio–temporal support. Some of them have attempted to provide full spatio–temporal support, but have poor performance for complex spatio–temporal aggregate queries. In addition, while the volume of sensor data is rapidly growing, the challenge of querying and managing the massive volumes of data generated by sensing devices still remains unsolved. In this article, we introduce EAGLE, a spatio–temporal query engine for querying sensor data based on the linked data model. The ultimate goal of EAGLE is to provide an elastic and scalable system which allows fast searching and analysis with respect to the relationships of space, time and semantics in sensor data. We also extend SPARQL with a set of new query operators in order to support spatio–temporal computing in the linked sensor data context.

Abstract. To enrich urban digital twins and better understand city evolution, the integration of heterogeneous, spatio-temporal data has become a large area of research in the enrichment of 3D and 4D (3D + Time) semantic city models. These models, which can represent the 3D geospatial data of a city and their evolving semantic relations, may require data-driven integration approaches to provide temporal and concurrent views of the urban landscape. However, data integration often requires the transformation or conversion of data into a single shared data format, which can be prone to semantic data loss. To combat this, this paper proposes a model-centric ontology-based data integration approach towards limiting semantic data loss in 4D semantic urban data transformations to semantic graph formats. By integrating the underlying conceptual models of urban data standards, a unified spatio-temporal data model can be created as a network of ontologies. Transformation tools can use this model to map datasets to interoperable semantic graph formats of 4D city models. This paper will firstly illustrate how this approach facilitates the integration of rich 3D geospatial, spatio-temporal urban data and semantic web standards with a focus on limiting semantic data loss. Secondly, this paper will demonstrate how semantic graphs based on these models can be implemented for spatial and temporal queries toward 4D semantic city model enrichment.

Abstract:
Purpose The purpose of this paper is to assess whether the temporal evolution of the normalized web distance (NWD) between significant terms concerning, e.g., a case of online activism can be used as a meta-data technique to measure evolution over time of, e.g., progress or decline of social empowerment. Design/methodology/approach The NWD between two terms has been identified as a quantitative measure for semantic proximity, ascertaining a defining relation between them. A trend analysis is made by performing on the internet a time window restrained series measurement of NWD of all combinations of key-terms and classifier-terms. Case defining key-terms, positive and negative discourse polarizing classifier-terms, and neutral classifier-terms for negative control need to be determined by discourse analysis of information on a targeted case. An example of NWD evolution from 1994 until 2013 is presented to measure the empowerment effects of the Wirikuta online movement on the Huichol people in Mexico. Findings The application of the NWD temporal evolution method to the Wirikuta case shows a slight but significant semantic change of the key-terms with respect to some of the positive and negative classifier-terms. The neutral classifier correctly shows no significant distance variation, as required for valid application of the method. The method provides indications for a complex image of empowerment of the Huichol identity. Research limitations/implications The accuracy of the method is limited due to short-term and between-user variability of the search tool’s page counts. More reliable access to a web-index will be required for more accurate NWD-based trend analysis. Practical implications The monitoring of temporal NWD evolution provides a potential tool for more comprehensive trend description compared to classical frequency based methods. Originality/value Trend analysis is key to internet research, to which the temporal NWD method provides an innovative contribution.

Abstract:
Ship behavior is the semantic expression of corresponding trajectory in spatial-temporal space. The intelligent identification of ship behavior is critical for safety supervision in the waterborne transport. In particular, the complicated behavior reflects the long-term intentions of a ship, but it is challenging to recognize it automatically for computers without a proper understanding. For this purpose, this study provides a method to model the behavior for computers from the perspective of knowledge modeling that is explainable. Based on our previous work, a semantic model for ship behavior representation is given considering the multi-scale features of ship behavior in cognitive space. Firstly, the multi-scale features of ship behavior are analyzed in spatial-temporal dimension and semantic dimension individually. Then, a method for multi-scale behaviors modeling from the perspective of semantics is determined, which divides the behavior scale into four sub-scales in cognitive space, considering spatial and temporal dimensions: action, activity, process, and event. Furthermore, an ontology model is introduced to construct the multi-scale semantic model for ship behavior, where behaviors with different semantic scales are expressed using the functions of ontology from a microscopic perspective to a macroscopic perspective consecutively. To validate the model, a case study is conducted in which ship behavior with different scales occurred in port water areas. Typical behaviors, which include leveraging the axioms expression and semantic web rule language (SWRL) of the ontology, are then deduced using a reasoner, such as Pellet. The results show that the model is reasonable and feasible to represent multi-scale ship behavior in various scenarios and provides the potential to construct a smart supervision network for maritime authorities.

Abstract:
The conversion of web services to semantic web comes the opportunity to automate various tasks. OWL-S plays a key role in describing web services behaviour. While ontology-based semantics given to OWL-S is structural rather than behaviourally oriented, we cannot automate an essential task in this field, verification. In this article, the mapping of OWL-S process model to Timed automata is investigated, which is a suitable formalism for real time systems modeling and automatic verification. Hence, this has led to not only enabling automatic verification but also covering problems related to automated verification of temporal quantitative properties as bounded liveness property. As a starting point, the OWL-S and sub entry of time ontologies for describing the timed behaviour of services has been chosen. A defined set of mapping rules is used to automatically encode control constructs defined in OWL-S and temporal information into timed automata. Also, it is shown how a Uppaal checker is used to check required properties formulated in TCTL. Finally, an EClinic case study is used to illustrate the technique.

Abstract:
Over the last few years, there has been an increasing di↵usion of Linked Data as a standard way to publish interlinked structured data on the Web, which allows users, and public and private organizations to fully exploit a large amount of data from several domains that were not available in the past. Although gathering and publishing such massive amount of structured data is certainly a step in the right direction, quality still poses a significant obstacle to the uptake of data consumption applications at large-scale. A crucial aspect of quality regards the dynamic nature of Linked Data where information can change rapidly and fail to reflect changes in the real world, thus becoming out-date. Quality is characterised by di↵erent dimensions that capture several aspects of quality such as accuracy, currency, consistency or completeness. In particular, the aspects of Linked Data dynamicity are captured by Time-Related Quality Dimen- sions such as data currency. The assessment of Time-Related Quality Dimensions, which is the task of measuring the quality, is based on temporal information whose collection poses several challenges regarding their availability, representation and diversity in Linked Data. The assessment of Time-Related Quality Dimensions supports data consumers in their decisions whether information are valid or not. The main goal of this thesis is to develop techniques for assessing Time-Related Quality Dimensions in Linked Data, which must overcome several challenges posed by Linked Data such as third-party applications, variety of data, high volume of data or velocity of data. The major contributions of this thesis can be summarized as follows: it presents a general settings of definitions for quality dimensions and measures adopted in Linked Data; it provides a large-scale analysis of approaches for representing temporal information in Linked Data; it provides a sharable and interoperable conceptual model which integrates vocabularies used to represent temporal information required for the assessment of Time-Related Quality Di- mensions; it proposes two domain-independent techniques to assess data currency that work with incomplete or inaccurate temporal information and finally it pro- vides an approach that enrich information with time intervals representing their temporal validity.

Abstract:
Given set of web pages labeled with ontological items, the level of similarity between two web pages is measured using the level of similarity between ontological items of pages labeled with. Using similarity measure between two pages, degree of similarity between two sequences of web page visits can be calculated as well. Using clustering algorithms, similar frequent sequences are grouped and representative sequences are selected from these groups. A new sequence is compared with all clusters and it is assigned to most similar one. Representatives of the most similar cluster can be used in several real world cases. They can be used for predicting and prefetching the next page user will visit or for helping the navigation of user in the website. They can also be used to improve the structure of website for easier navigation. In this study the effect of time spent on each web page during the session is analyzed.

Abstract:
Découvrir les environs tout en marchant à l'aide d'un appareil mobile est désormais possible en associant les nouvelles technologies telles que la réalité augmentée (RA) et les services basés sur la localisation. De nombreuses applications mobiles ont été conçues à cet effet récemment. Les environs d'un utilisateur en mouvement sont présentés sur l'écran de son appareil mobile en utilisant les données de géo-localisation et elle peut interagir avec son environnement grâce à une couche d'information numérique superposée sur la scène capturée. Toutefois, la quantité d'informations géo-référencées produites et accessibles augmentant chaque jour, il y a un besoin croissant d'une approche générique qui vise à présenter l'information de manière structurée et adaptée aux différents domaines d'application et à la diversité des profils des utilisateurs.Notre travail se concentre sur la définition d'un modèle de données pour les objets 3D destiné à être intégré dans des applications de RA mobiles. Le modèle de données que nous proposons donne accès à l'information spatio-temporelle et thématique disponible sur les objets du monde réel. Alors que la réalité augmentée semble être bien adaptée pour la recherche d'informations à partir de la localisation, la plupart des approches basées sur la RA se concentre sur des scénarios spécifiques à un domaine d'application. D'autre part, le nuage des données ouvertes et liées (LOD Cloud en anglais) est un ensemble en constante extension de données structurées et publiées sur le Web. Il contient donc de grandes quantités d'informations à références spatio-temporelles qui peuvent être exploitées par les applications mobiles et présentées en utilisant la RA pour favoriser l'interaction. Dans notre recherche, ce nuage du Web des Données sert de source principale d'information au cours de l'expérience de découverte des environs à l'aide de la RA proposée à l'utilisateur.À cette fin, nous publions sur le Web les objets 3D correspondant aux objets du monde réel en utilisant notre modèle de données, ce qui permet de les lier avec le nuage du Web des Données. De fait, un objet du monde réel peut être représenté selon trois dimensions d'information : thématique (qui décrit les rôles ou fonctions de l'objet), spatiale (à travers sa géométrie 3D), et temporelle (par la période qui correspond à son existence). De plus, chaque changement dans la vie d'un objet du monde réel est représenté dans le modèle par des informations sémantiques. En conséquence, sur son appareil mobile, l'utilisateur visualise une vue de RA construite avec des modèles 3D légers et transparents. Il peut interagir avec ces objets de RA afin d'accéder aux informations relatives aux objets du monde réel correspondants qui se trouvent aux alentours et vers lesquels il pointe son téléphone mobile. Ces objets de RA permettent à l'utilisateur de construire mentalement la relation référentielle entre les objets virtuels et réels, tandis que le développeur de l'application mobile peut créer des expériences basées sur des thématiques différentes disponibles à travers sur le nuage du Web des Données (architecture, histoire, gastronomie, loisirs, etc.).En nous appuyant sur cette base de connaissances conceptualisée, nous proposons une architecture appelée ARCAMA-3D (Réalité Augmentée et 3D pour les applications mobiles sensibles au contexte), dont les modules permettent aux concepteurs et développeurs de créer leurs propres applications de RA pour différents domaines en étant en mesure d'étendre le modèle de données, de lier les modèles 3D avec d'autres ensembles de données ouvertes et liées disponibles dans le nuage, et d'alimenter ces applications de découverte à partir de sources de données spécifiques. Notre proposition est illustrée sur le cas d'étude que constitue le Monastère Royal de Brou, en France, à travers un scénario de cas d'utilisation pour un utilisateur visitant ce monument historique
Discovering the surroundings while walking using a mobile device is now possible by coupling new technologies such as Augmented Reality (AR) and location-based services. Many mobile applications have been designed for that purpose recently. The surroundings of the user are presented on the screen of her mobile device using the location data and she can interact with her environment through a digital information layer superimposed on the captured scene. However, since the amount of geo-referenced information increases every day, there is a growing need for a generic approach that aims at presenting information in a structured manner and adapted to different application domains and users profiles.Our work focuses on the definition of a data model for 3D objects to be used in mobile AR applications. The data model we propose prioritizes access to available spatiotemporal and thematic information about real-world objects. While Augmented Reality appears to be well-suited for searching location-based information, most of the AR approaches focus on domain specific scenarios and we observe that there is no generic data model dedicated to information search and discovery that could be re-used in various AR applications. On the other hand, Linked Open Data (LOD) cloud is an ever-growing set of structured and interlinked datasets published on the Web. It contains vast amounts of spatiotemporal information that can be exploited by location-based mobile applications and presented using AR for fostering interaction. In our research, the LOD cloud serves as a basis for information retrieval during the AR experience of the user.For this purpose, we first publish 3D objects that correspond to real-world objects (buildings, monuments, etc.) on the Web by using our data model and interlink them with data sources on the LOD cloud. Then, using our data model, any real-world object can be represented by three informational dimensions: themes (describing the roles or functions of this object), space (through its 3D geometry), and time (the period linked to its existence). Each change in the life of a real-world object is represented in the model by semantic information following the LOD publishing principles. This allows a binding between the content of our data model and the LOD cloud. As a consequence, on her mobile device, the user visualizes an AR view built with light and transparent 3D models. She can interact with these AR objects in order to access to information related to the corresponding real-world objects of her surroundings she is pointing at. These AR objects allow the user to mentally construct the referential relationships between virtual and real-world objects, while the mobile application developer can create experiences based on different concepts found on the cloud (thematic and temporal concepts, etc.). This way, the LOD cloud, as a growing and updated structured source of semantic data, becomes the main source of information and facilitates knowledge discovery in AR applications.Using this conceptualized knowledge base, we propose our architecture, called ARCAMA-3D (Augmented Reality for Context Aware Mobile Applications with 3D), whose modules allow application designers and developers to create their own AR applications for different domains by being able to extend the data model, bind 3D models with other data sources on the LOD cloud, cover a selected part of LOD and feed their application only with these specific data sources. We develop our ideas working on the case study of the Royal Monastery of Brou, in France, and implement a use case scenario for a user visiting the monastery

This work is part of the ICS Project, which has been developed in LSI at UFMA under the coordinator Sofiane Labidi s assistance. The main objective is to develop an intelligent environment to deal with the last two phases of the ICS lifecycle: the Formation and Fulfillment of Contracts. The ICS architecture and environment are presented as well as its development aspects. An implemented system that uses intelligent agent has the possibility to automatize the mechanism of closed deal contract among ICS users, as well as the monitoring of its assumed obligations. We propose the use of patterns and Semantic Web tools to deal with the information management included in the contracts. Related to the monitoring we propose a model that makes use of the Temporal Workflow and of active rules based on the ECAA s paradigm of Active Database System.

L'information géographique peut être perçue selon trois dimensions : une dimension spatiale (e.g., ville), une dimension temporelle (e.g., date) et une dimension alphanumérique (e.g., population). L'intégration de ces différents types de données est l'un des challenges actuels de la production d'applications permettant la représentation et le traitement d'informations géographiques. Nous nous proposons de contribuer à cette problématique en proposant une méthode afin d'aider à la gestion de la cohérence des données impliquant deux des trois dimensions. Cette cohérence peut se poser après application d'un opérateur sur les informations géographiques. La méthode que nous proposons est basée sur des liens sémantiques entre les dimensions. Une liaison sémantique représente le rapport logique entre les dimensions. Cette liaison associée à des règles de comportement des opérateurs de manipulation, nous permet de garantir la cohérence du modèle de données associé au résultat d’un opérateur

Abstract:
Dans ce travail de thèse, nous proposons une base de connaissances, destinée à une prothèse de mémoire « intelligente », appelée CaptainMemo, qui a pour but d’aider les malades d’Alzheimer, à pallier leurs problèmes de dégénérescence mnésique. Cette base de connaissances est basée sur l’ontologie temporelle, multiculturelle et multilingue PersonLink, permettant à la prothèse de mémoire une représentation sémantique rigoureuse, multilingue et temporelle des liens interpersonnels. L’ontologie PersonLink est déréférençable et présente dans le Web de données.Le multilinguisme et la représentation temporelle sont deux grands sujets de recherche en informatique et en Web sémantique en particulier. Le multilinguisme appliqué à la représentation des relations interpersonnelles requiert un traitement spécifique, car il est lié au multiculturalisme. Par ailleurs, le passage d’une culture/langue à une autre s’avère une grande problématique de recherche. En effet, la traduction littérale n’est pas toujours permise, surtout quand il s’agit des relations interpersonnelles, car elles sont culturellement dépendantes. Dans ce contexte, nous proposons une approche permettant la représentation des ontologies dans plusieurs cultures/langues. Cette approche, en se basant sur un algorithme de traduction, permet le passage d’une culture/langue à une autre sans faire de la traduction littérale mais plutôt une traduction culturelle. Ainsi, en adoptant cette approche, notre ontologie PersonLink permet une représentation exacte des relations interpersonnelles, qui prend en considération l’aspect culturel pour la définition de chaque relation, et lui attribue le terme adéquat selon la langue liée à la culture dans laquelle elle est représentée. Les relations interpersonnels régissent à des règles et contraintes qui les définissent selon chaque culture, ces contraintes sont représentées sémantiquement dans l’ontologie PersonLink via OWL2. Cependant, il est difficile de prendre en considération ces contraintes lors de l’introduction de la dimension temporelle pour représenter les intervalles de temps de ces relations interpersonnelles, surtout quand ces dernières sont diachroniques et leurs intervalles de temps sont qualitatifs. En effet, les modèles et solutions déjà existantes permettent de faire une représentation temporelle des intervalles de temps (ex 4D-Fluents), et de lier entre ces intervalles de temps (ex Relations d’Allen), mais ne prennent pas en considération les contraintes sémantiques des relations interpersonnelles. Dans ce sens, nous proposons une approche qui permet une représentation sémantique, basée sur les contraintes OWL2, pour la représentation des intervalles de temps qualitatifs. Enfin, pour traiter l’intelligence de la prothèse de mémoire CaptainMemo, nous proposons une approche pour le raisonnement sur les intervalles dans le temps. Dans cette approche nous introduisons un ensemble de règles SWRL pour affirmer des relations d’Allen temporelles inférées, permettant aux raisonneurs, tel que Pellet qui prend en charge les règles DL-Safe, d’être employés pour l'inférence et la vérification de la cohérence sur les relations temporelles entre différents intervalles de temps. La table des compositions des relations entre intervalles de temps a ainsi été considérablement réduite, car elle se base sur un ensemble tractable de ces relations, ce qui en résulte un temps de traitement de raisonnement plus réduit
In this thesis, we propose a knowledge base for a "smart" memory prosthesis, called CaptainMemo, which aims to help Alzheimer's patients to overcome their memory impairments. This knowledge base is built over the temporal, multicultural and multilingual PersonLink ontology. This ontology gives the memory prosthesis a rigorous, multilingual and temporal semantic representation of interpersonal relationships. The PersonLink ontology is dereferenceable and available in the Linked Data. Multilingualism and temporal representation are two major research topics in computer science and in the Semantic Web in particular.Multilingualism applied to the representation of interpersonal relationships requires specific treatment because it is linked to multiculturalism. In addition, the transition from one culture / language to another is a major research problem. Indeed, literal translation is not always allowed, especially when it comes to interpersonal relationships, because they are culturally dependent. In this context, we propose an approach allowing the representation of ontologies in several cultures / languages. This approach, based on a translation algorithm, allows the transition from one culture / language to another by making a cultural translation rather than a literal one. Thus, by adopting this approach, our PersonLink ontology allows an exact representation of interpersonal relationships, because it takes into consideration the cultural aspect for the definition of each relationship, and assigns the appropriate term according to the language related to this culture. Interpersonal relationships are governed by rules and constraints that define them according to each culture, these constraints are represented semantically in the PersonLink ontology using OWL2. However, it is difficult to consider these constraints when introducing the temporal dimension to represent the time intervals of these interpersonal relationships, especially when these are diachronic and their time intervals are qualitative. Indeed, the legacy models and solutions make it possible to make a temporal representation of the time intervals (e.g. 4D-Fluents), and to link between these time intervals (e.g. Allen Relations), but do not take into account the semantics constraints of interpersonal relationships. In this context, we propose an approach that allows a semantic representation, based on OWL2 constraints, for the representation of qualitative time intervals. Finally, to deal with the intelligence of the CaptainMemo memory prosthesis, we propose an approach for reasoning over time intervals. In this approach we introduce a set of SWRL rules to assert inferred temporal Allen relationships, allowing reasoners, such as Pellet that supports DL-Safe rules, to be used for the inference and the verification of consistency over the temporal relationships between different time intervals. Thus, the table of compositions of the relations between time intervals has been considerably reduced, since it is based on a tractable set of these relations, and, consequently, the processing time of the reasoning becomes shorter

Abstract:
Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies.
Dhaka City is the capital of Bangladesh and boundary revisions of Dhaka city refers to the changes of Dhaka city administrative boundary or jurisdiction over time. Dhaka is growing very fast in terms of population and area. So, government is redefining city boundaries and also making big units into several parts for better city management. Now, the challenge is to deal with these changes of administrative regions that seem to be helpful to match with census record that comes out every ten to fifteen years. Dhaka city boundary revisions dataset contains data about the name of the administrative unit, type of administrative unit, year of establishment, year of data record, geometry of administrative unit defining the jurisdiction, type of revisions occurred in the administrative units, time of revisions and the number of subdivisions inside an administrative unit. This thesis aims to integrate Dhaka city boundary revision dataset using semantic web technology that preserves information about changes occurred in the Dhaka city boundary over time.

Abstract:
This chapter offers a functional account of why the mind—when free from the demands of a task or the constraints of heightened emotions—tends to wander from one topic to another, in a ceaseless and seemingly random fashion. We propose the default variability hypothesis, which builds on William James’s phenomenological account of thought as a form of mental locomotion, as well as on recent advances in cognitive neuroscience and computational modeling. Specifically, the default variability hypothesis proposes that the default mode of mental content production yields the frequent arising of new mental states that have heightened variability of content over time. This heightened variability in the default mode of mental content production may be an adaptive mechanism that (1) enhances episodic memory efficiency through de-correlating individual episodic memories from one another via temporally spaced reactivations, and (2) facilitates semantic knowledge optimization by providing optimal conditions for interleaved learning.

Abstract:
In ontology-based systems that process data stemming from different sources and that is received over time, as in context-aware systems, reasoning needs to cope with the temporal dimension and should be resilient against inconsistencies in the data. Motivated by such settings, this paper addresses the problem of handling inconsistent data in a temporal version of ontology-based query answering. We consider a recently proposed temporal query language that combines conjunctive queries with operators of propositional linear temporal logic and extend to this setting three inconsistency-tolerant semantics that have been introduced for querying inconsistent description logic knowledge bases. We investigate their complexity for DL-LiteR temporal knowledge bases, and furthermore complete the picture for the consistent case.
