Full textEs un hecho reconocido que el intercambio de información entre organismos y agencias mejora la eficiencia y efectividad en dominios con alto impacto en la sociedad, tales como seguridad, ciberseguridad y salud pública. Por tanto, no es una sorpresa que el desarrollo de la interoperabilidad entre organismos públicos sea una prioridad política en muchos países y que, en la actualidad, se esté trabajando en diversas iniciativas con esta finalidad. La correcta gestión de tales iniciativas requiere instrumentos adecuados, que puedan soportar la definición de la situación existente y la deseada, así como la identificación, priorización, monitorización y control de las acciones que son necesarias para conseguir los objetivos definidos para alcanzar la interoperabilidad. Asimismo, son necesarios instrumentos que permitan justificar y comparar diferentes iniciativas, por ejemplo, en situaciones en las que compitan por financiación. Sin embargo, actualmente las soluciones que ofrecen instrumentos reutilizables para estos propósitos son escasas, y aquellas que existen no cubren bien todos los requisitos. En este contexto, esta tesis doctoral propone un nuevo marco teórico llamado iShare para evaluar la interoperabilidad semántica, uno de los aspectos de la interoperabilidad, de organismos gubernamentales y/o agencias que utilicen un modelo de información común para el intercambio de datos entre ellos. Con iShare, esta evaluación se realiza en dos etapas. En la primera, se evalúa el rendimiento de las organizaciones en términos de interoperabilidad semántica, mientras que en la segunda etapa se evalúa la relevancia de ese rendimiento medido, considerando una serie de factores predeterminados. Para el desarrollo del marco teórico iShare, se utilizó la metodología de investigación Design Science, basada en los indicadores de rendimiento de proceso, en el método Delphi y el modelo Weighted Sums Model. Para su validación, se aplicó el mismo al desarrollo del sistema de vigilancia marítima NIPIMAR en Portugal, el cual está orientado al intercambio de datos y utiliza el modelo de información del programa europeo Maritime CISE (Common Information Sharing Environment for Maritime Surveillance, entorno común de intercambio de datos para vigilancia marítima). El proceso de validación permitió evaluar la interoperabilidad semántica de seis organismos públicos que participaban en el proyecto. Asimismo, algunas de las ideas del marco teórico fueron directamente incorporadas al proyecto para evaluar la interoperabilidad semántica de todos los organismos públicos portugueses y para desarrollar un plan de acción que mejore su interoperabilidad y el intercambio de información entre ellas. Los resultados de esta investigación demuestran que el marco teórico iShare ofrece una solución innovadora, útil, relevante y más objetiva para la evaluación de la interoperabilidad semántica entre varias organizaciones. Por todo ello, el marco teórico iShare contribuye al cuerpo de conocimiento en este campo científico y abre nuevas posibilidades para evaluar la interoperabilidad y así aumentar la eficiencia y la eficacia de las agencias gubernamentales.

Full textTiivistelmä Älytilavision ydinajatuksena on, että erilaiset laitteet tuottavat yhteistyössä ihmisten elämää helpottavia palveluita. Vision toteutumisen kannalta on tärkeää saavuttaa semanttisen tason yhteentoimivuus laitteiden välillä. Tämän väitöskirjan tavoitteena on mahdollistaa semanttisen webin teknologioihin pohjautuva yhteentoimivuus älytilan laitteiden välillä. Monenlaisia haasteita täytyy ratkaista, ennen kuin tämä tavoite voidaan saavuttaa. Tässä työssä keskityttiin seuraaviin neljään haasteeseen: Ensimmäinen haaste on, että semanttisen webin teknologioita ei ole suunniteltu reaaliaikaiseen kommunikaatioon, eivätkä ne sovellu isojen tiedostojen jakamiseen. Tämän vuoksi on haasteellista hyödyntää niitä älytiloissa, joissa laitteet tyypillisesti jakavat tällaista tietoa. Toinen haaste on, että semanttisen webin teknologiat perustuvat syntakseihin ja koodausformaatteihin, jotka tuottavat laitteiden kannalta tarpeettoman pitkiä viestejä. Tämä tekee niiden hyödyntämisestä hankalaa resurssirajoittuneissa laitteissa ja verkoissa. Kolmas haaste on, että älytiloissa hyödynnetään hyvin erilaisia kommunikaatioteknologioita, minkä vuoksi jopa tiedonsiirto laitteiden välillä on haasteellista. Neljäs haaste on tarjota loppukäyttäjälle helppoja menetelmiä sekä vuorovaikutukseen semanttiseen webiin pohjautuvien älytilojen kanssa että tällaisen älytilan muokkaamiseen käyttäjän tarpeiden mukaiseksi. Vaikka laitteiden itsenäinen toiminta onkin älytilojen perusajatuksia, tämä on kuitenkin tärkeää teknologian hyväksymisen ja käyttöönoton kannalta. Väitöskirjan päätulos on laitteiden semanttisen yhteentoimivuuden viitekehys, joka koostuu seuraavista itsenäisistä kontribuutioista: 1) semanttisen tason yhteentoimivuusarkkitehtuuri älytiloille, 2) tiedonjakoprotokolla resurssirajoittuneille laitteille ja verkoille sekä 3) menetelmä semanttiseen webiin pohjautuvien älytilojen konfigurointiin. Näiden kontribuutioiden evaluointi suoritettiin erilaisten järjestelmäkomponenttien referenssitoteutuksilla ja prototyyppiälytiloilla, jotka kuuluvat myös väitöskirjan keskeisiin kontribuutioihin

Full textIn order to interact and collaborate effectively, agents, whether human or software, must be able to communicate through common understandings and compatible conceptualisations. Ontological differences that occur either from pre-existing assumptions or as side-effects of the process of specification are a fundamental obstacle that must be overcome before communication can occur. Similarly, the integration of information from heterogeneous sources is an unsolved problem. Efforts have been made to assist integration, through both methods and mechanisms, but automated integration remains an unachieved goal. Communication and information integration are problems of meaning and interaction, or semantic interoperability. This thesis contributes to the study of semantic interoperability by identifying, developing and evaluating three approaches to the integration of information. These approaches have in common that they are lightweight in nature, pragmatic in philosophy and general in application.
The first work presented is an effort to integrate a massive, formal ontology and knowledge-base with semi-structured, informal heterogeneous information sources via a heuristic-driven, adaptable information agent. The goal of the work was to demonstrate a process by which task-specific knowledge can be identified and incorporated into the massive knowledge-base in such a way that it can be generally re-used. The practical outcome of this effort was a framework that illustrates a feasible approach to providing the massive knowledge-base with an ontologically-sound mechanism for automatically generating task-specific information agents to dynamically retrieve information from semi-structured information sources without requiring machine-readable meta-data.
The second work presented is based on reviving a previously published and neglected algorithm for inferring semantic correspondences between fields of tables from heterogeneous information sources. An adapted form of the algorithm is presented and evaluated on relatively simple and consistent data collected from web services in order to verify the original results, and then on poorly-structured and messy data collected from web sites in order to explore the limits of the algorithm. The results are presented via standard measures and are accompanied by detailed discussions on the nature of the data encountered and an analysis of the strengths and weaknesses of the algorithm and the ways in which it complements other approaches that have been proposed.
Acknowledging the cost and difficulty of integrating semantically incompatible software systems and information sources, the third work presented is a proposal and a working prototype for a web site to facilitate the resolving of semantic incompatibilities between software systems prior to deployment, based on the commonly-accepted software engineering principle that the cost of correcting faults increases exponentially as projects progress from phase to phase, with post-deployment corrections being significantly more costly than those performed earlier in a project’s life. The barriers to collaboration in software development are identified and steps taken to overcome them. The system presented draws on the recent collaborative successes of social and collaborative on-line projects such as SourceForge, Del.icio.us, digg and Wikipedia and a variety of techniques for ontology reconciliation to provide an environment in which data definitions can be shared, browsed and compared, with recommendations automatically presented to encourage developers to adopt data definitions compatible with previously developed systems.
In addition to the experimental works presented, this thesis contributes reflections on the origins of semantic incompatibility with a particular focus on interaction between software systems, and between software systems and their users, as well as detailed analysis of the existing body of research into methods and techniques for overcoming these problems.

Doctoral thesis, Norwegian University of Science and Technology, Department of Computer and Information Science, 2008. http://urn.kb.se/resolve?urn=urn:nbn:no:ntnu:diva-2119.
Full textBusiness process models representing process knowledge about doing business are necessary for designing Information Systems (IS) solutions in enterprises. Interoperability of business process knowledge in legacy systems is crucial for enterprise systems interoperation and integration due to increased enterprise cooperation and business exchange. Many modern technologies and approaches are deployed to support business process interoperability either at the instance level or the protocol level, such as BPML, WSDL and SOAP. However, we argue that a holistic approach is necessary for semantic interoperability of business process models at the conceptual level when considering the process models as reusable process knowledge for other (new or integrated) IS solutions. This brings requirements to manage semantic heterogeneity of process knowledge in process models which are distributed across different enterprise systems. Semantic annotation is an approach to achieve semantic interoperability of heterogeneous resources. However, such an approach has usually been applied to enhance the semantics of unstructured and structured artifacts (e.g. textual resources [72] [49], and Web services [166] [201]).
The aim of the research is to introduce an ontology-based semantic annotation approach to enrich and reconcile semantics of process models — a kind of semi-structured artifact, for managing process knowledge. The approach brings together techniques in process modeling, ontology building, semantic matching, and Description Logic inference in order to provide a comprehensive semantic annotation framework. Furthermore, a prototype system that supports the process of ontology-based semantic annotation of heterogeneous process models is described. The applicational goal of our approach is to facilitate process knowledge management activities (e.g. discovery, reuse, and integration of process knowledge/models) by enhanced semantic interoperability.
A survey has been performed through identifying semantic heterogeneity in process modeling and investigating semantic technology from theoretical and practical views. Based on the results from the survey, a comprehensive semantic annotation framework has been developed, which provides a method to manage semantic heterogeneity of process models from the following perspectives. First, basic descriptions of process models (profile annotation); second, process modeling languages (meta-model annotation); third, contents of process models (model annotation) and finally intentions of process model owners (goal annotation). Applying the semantic annotation framework, an ontology-based annotation method has been elaborated, which results in two categories of research activity — ontology building and semantic mapping. In ontology building, we use Web Ontology Language (OWL), a Semantic Web technology, which can be used to model ontologies. GPO (General Process Ontology) comprising core concepts in most process modeling languages is proposed; domain concepts are classified in the corresponding categories of GPO as a domain ontology; design principles for building a goal ontology are introduced in order to serve the annotation of process models pragmatically. In semantic mapping, a set of mapping strategies are developed to conduct the annotation by considering the semantic relationships between model artifacts and ontology references and as well the semantic inference mechanism supported by OWL DL (Description Logic). The annotation method is finally formalized into a process semantic annotation model - PSAM.
The proposed approach has been implemented in a prototype annotation tool —ProSEAT to facilitate the annotation process. Procedures of applying the semantic annotation approach with the tool are described through exemplar study. The annotation approach and the prototype tool are evaluated using a quality framework. Furthermore, the applicability of the annotation results is validated by going through a process knowledge management application. The Semantic Web Rule Language (SWRL) is applied in the application demonstration. We argue that the ontology-based annotation approach combined with the Semantic Web technology is a feasible approach to reconcile semantic heterogeneity in the process knowledge management. Limitations and future work are discussed after concluding this research work.
The contributions of this thesis are summarized as follows. First, a general process ontology is proposed for unifying process representations at a high level of abstraction. Second, a semantic annotation framework is introduced to describe process knowledge systematically. Third, ontology-based annotation methods are elaborated and formalized. Fourth, an annotation system, utilizing the developed formal methods, is designed and implemented. Fifth, a process knowledge management system is outlined as the platform for manipulating the annotation results. Moreover, applying results of the approach is demonstrated through a process model integration example.

Full textLa Computación Distribuida es un paradigma donde la ejecución de aplicaciones se distribuye entre diferentes computadores contados a través de una red de comunicación. Las plataformas de computación distribuida han evolucionado rápidamente durante las últimas décadas, empezando por los "Clusters", donde varios computadores están conectados por una red local; pasando por los "Grids", donde los recursos computacionales son compartidos por varias instituciones creando un red de computación global; llegando finalmente a lo que actualmente conocemos como "Clouds", donde nos podemos proveer de recursos de manera dinámica, bajo demanda y pagando solo por lo que consumimos. Actualmente, varias compañías están descubriendo los beneficios de mover sus aplicaciones a las infraestructuras Cloud, desacoplando la administración de los recursos computacionales de su "core business" para ser más productivos. Sin embargo migrar el software al Cloud no es una tarea fácil porque se requiere un conocimiento exhaustivo de la tecnología y como usar los servicios ofrecidos por los diferentes proveedores. Además cada proveedor ofrece recursos con diferentes capacidades, precios y calidades, con su propia interfaz para acceder a ellos. Por consiguiente, cuando un usuario quiere ejecutar una aplicación en el Cloud, debe entender que ofrece cada proveedor y como usarlo y una vez que ha elegido debe programar los diferentes pasos del despliegue de su aplicación. Si además se quieren usar varios proveedores o cambiar a otro, este proceso debe repetirse varias veces. Esta tesis presenta varias contribuciones para mitigar estos problemas diseñando una plataforma para facilitar y automatizar la integración de aplicaciones en los diferentes proveedores. Estas contribuciones se dividen en varias partes: Primero, el estudio de como las tecnologías semánticas pueden ayudar para describir aplicaciones y automáticamente inferir como se puede desplegar en un plataforma distribuida. Una vez obtenemos este modelo de despliegue, la segunda contribución nos presenta como estas mismas tecnologías pueden usarse para asignar las diferentes partes del despliegue de la aplicación a los recursos de los proveedores. Una vez sabemos la asignación, la siguiente contribución nos resuelve como se puede usar "AI planning" para encontrar la secuencia de servicios que se deben ejecutar para realizar el despliegue deseado. Finalmente, la última parte de la tesis, nos presenta como el despliegue y ejecuciones de las aplicaciones puede coordinarse por un sistema multi-agentes de una manera escalable y distribuida. Las diferentes contribuciones de la tesis han sido validadas mediante la implementación de prototipos y casos de uso.

Full textThe Health Ontology Mapper (HOM) method is a proposed solution to the semantic gap problem. The HOM Method provides the following functionality to enable the scalable deployment of informatics systems involving data from multiple health systems. The HOM method allows a relatively small population of biomedical ontology experts to describe the interpretation and analysis of biomedical information collected at thousands of hospitals via a cloud based terminology server. As such the HOM Method is focused on the scalability of the human talent required for successful informatics projects. The HOM promotes a means of converting UML based medical data into OWL format via a cloud-based method of controlling the data loading process. HOM subscribes to a means of converting data into a HIPAA Limited Data Set format to lower the risk associated with developing large virtual data repositories. HOM also provides a means of allowing access to medical data over grid computing environments by translating all information via a centralized web-based terminology server technology.
An integrated data repository (IDR) containing aggregations of clinical, biomedical, economic, administrative, and public health data is a key component of research infrastructure, quality improvement and decision support. But most available medical data is encoded using standard data warehouse architecture that employs arbitrary data encoding standards, making queries across disparate repositories difficult. In response to these shortcomings the Health Ontology Mapper (HOM) translates terminologies into formal data encoding standards without altering the underlying source data. The HOM method promotes inter-institutional data sharing and research collaboration, and will ultimately lower the barrier to developing and using an IDR.

Full textA desirable goal of military simulation training is to provide large scale or joint exercises to train personnel at higher echelons. To help meet this goal, many of the lower echelon combatants must consist of computer generated forces with some of these echelons composed of units from different simulations. The object of the research described is to correlate the behaviors of entities in different simulations so that they can interoperate with one another to support simulation training. Specific source behaviors can be translated to a form in terms of general behaviors which can then be correlated to any desired specific destination simulation behavior without prior knowledge of the pairing. The correlation, however, does not result in 100% effectiveness because most simulations have different semantics and were designed for different training needs. An ontology of general behaviors and behavior parameters, a database of source behaviors written in terms of these general behaviors with a database of destination behaviors. This comparison is based upon the similarity of sub-behaviors and the behavior parameters. Source behaviors/parameters may be deemed similar based upon their sub-behaviors or sub-parameters and their relationship (more specific or more general) to destination behaviors/parameters. As an additional constraint for correlation, a conversion path from all required destination parameters to a souce parameter must be found in order for the behavior to be correlated and thus executed. The length of this conversion path often determines the similarity for behavior parameters, both source and destination. This research has shown, through a set of experiments, that heuristic metrics, in conjunction with a corresponding behavior and parameter ontology, are sufficient for the correlation of heterogeneous simulation behavior. These metrics successfully correlated known pairings provided by experts and provided reasonable correlations for behaviors that have no corresponding destination behavior. For different simulations, these metrics serve as a foundation for more complex methods of behavior correlation.

Full textCom a evolução da Web atual para a Web Semântica, acredita- se que as informações disponíveis estarão estruturadas de forma a permitir o processamento automático de seu conteúdo por máquinas. Além do processamento individual, deseja-se uma melhor troca de informações entre aplicações Web. Para estes propósitos, são necessários mecanismos que garantam a interoperabilidade semântica, i.e., identificação e compatibilidade de informações. Neste sentido, ontologias são utilizadas como um recurso para disponibilizar um vocabulário estruturado e livre de ambigüidades. Ontologias fornecem um padrão bem definido para a estruturação da informação e promovem um formalismo passível de processamento automático. Neste trabalho, propomos uma estratégia para interoperabilidade de ontologias. O Componente para Alinhamento Taxonômico de Ontologias - CATO, resultado da implementação desta estratégia proposta, alinha automaticamente as taxonomias de ontologias comparadas. O alinhamento realizado é obtido em três etapas executadas seqüencialmente. A primeira etapa compara lexicalmente os conceitos das ontologias entradas e usa um mecanismo de poda estrutural dos conceitos associados como condição de parada. A segunda etapa compara estruturalmente as hierarquias das ontologias identificando as similaridades entre suas sub-árvores comuns. A terceira etapa refina os resultados da etapa anterior classificando os conceitos identificados como similares em bem similares ou pouco similares, de acordo com um percentual de similaridade prédefinido.
With the Web evolving towards a Semantic Web, it is believed that the available information will be presented in a meaningful way to allow machines to automatically process its content. Besides the individual processing, a better information exchange among Web applications is desired. For this purpose, mechanisms are called for guarantee the semantic interoperability, that is, the identification and compatibility of information. In this direction, ontologies are used as one resource to make available a structured vocabulary, free of ambiguities. Ontologies provide a well-defined standard to structure the information and to promote formalism for automatic processing. In this work, we propose one strategy for ontology interoperability. The Ontology Taxonomic Alignment Component - CATO, which is the result of the implementation of this proposed strategy, provides an automatic taxonomic ontologies alignment. In this way, the alignment is obtained by a three-step process. The first step is the lexical comparison between the concepts from the entries ontologies. It uses a trimming mechanism of the related associated concepts as a stop condition. The second step is the structural comparison of the ontologies structures used to identify the similarities between common sub-trees. The third step refines the results of the previous step, classifying the similar identified concepts as very similar or little similar, according to a pre-defined similarity measurement.

Full textEnsuring personal data ownership and interoperability for decentralized social Web applications is currently a debated topic, especially when taking into consideration the aspects of privacy and access control. Since the user's data are such an important asset of the current business models for most social Websites, companies have no incentive to share data among each other or to offer users real ownership of their own data in terms of control and transparency of data usage. We have concluded therefore that it is important to improve the social Web in such a way that it allows for viable business models while still being able to provide increased data ownership and data interoperability compared to the current situation. To this regard, we have focused our research on three different topics: identity, authentication and access control. First, we tackle the subject of decentralized identity by proposing a new Web standard called "Web Identity and Discovery" (WebID), which offers a simple and universal identification mechanism that is distributed and openly extensible. Next, we move to the topic of authentication where we propose WebID-TLS, a decentralized authentication protocol that enables secure, efficient and user friendly authentication on the Web by allowing people to login using client certificates and without relying on Certification Authorities. We also extend the WebID-TLS protocol, offering delegated authentication and access delegation. Finally we present our last contribution, the Social Access Control Service, which serves to protect the privacy of Linked Data resources generated by users (e.g. pro le data, wall posts, conversations, etc.) by applying two social metrics: the "social proximity distance" and "social contexts"

Full textTechnological advancements in computing have led to a reality where computational devices are more mobile, connected and context aware than ever before. Several of these devices are primarily designed for or support the creation of digital content via built-in or attachable sensors, e.g. mobile phones. The portability and connectivity of mobile devices make them suitable tools to support learning experiences; their features can be used to generate digital content and metadata related to the particular learning situation. These types of objects, referred to as Emerging Learning Objects (ELOs), introduce challenges in terms of metadata enrichment as their metadata should reflect aspects related to the particular learning situation in which they were created to be properly indexed. A claim made in this thesis is that semantic interoperability of ELO metadata is an integral concern that needs to be explored in order to benefit from these metadata outside custom tailored applications and systems. Therefore, the main research question explored in this thesis focuses on the ability to enrich ELOs with semantically interoperable contextual metadata.
This thesis is comprised of a collection of five peer-reviewed articles that describe interrelated stages of research in pursuit of an answer to the main research question. The overall research process consisted of three main stages: a literature review; the development a system artefact; and the exploration of the technological solution (Linked Data) applied in the system artefact. An instantiation of the Unified Process guided the development of the system artefact.
The outcomes of these activities provide insights on how to perceive the relationship between context and contextual metadata, as well as properties related to a particular technological solution, namely data distribution, flexibility and expressivity. In order to decouple the findings from a particular instance of technology, a generalization effort in the analysis identified two generic factors that affect the semantic interoperability of metadata: the level of ontological consensus and the level of metadata expressivity. The main conclusion of this thesis is that until the constituent parts of context are agreed upon, metadata expressivity is an important feature for promoting semantic interoperability of ELO contextual metadata.Technological advancements in computing have led to a reality where computational devices are more mobile, connected and context aware than ever before.

Of particular interest is the use of the Data Distribution Service (DDS) open standard to integrate the component of any given command and control system working in a denied network environment. The method used for this research includes a review of past literature on the different specification to implement semantic interoperability for better and more efficient integration, as well as an exploration of the different functionalities and capabilities of DDS. We present a middleware design based on the DDS specifications as developed by the Object Management Group. The design was influenced by the different limitations and requirements of the networking environment. Meanwhile, the proposed architecture also offers ways to implement semantic interoperability solutions in the system. Finally, the thesis describes a deployment scenario with a small network in order to accurately define the system controls that could impact the overall functionality of the DDS design, primarily through the Quality of Service (QoS) provisions.

Full textIn this day and age, enterprises often find that their business benefits greatly if they collaborate with others in order to be more competitive and productive. However these collaborations often come with some costs since the worldwide diversity of communities has led to the development of various knowledge representation elements, namely ontologies that, in most cases, are not semantically equivalent. Consequently, even though some enterprises may operate in the same domain, they can have different representations of that same knowledge. However, even after solving this issue and establishing a semantic alignment with other systems, they do not remain unchanged. Subsequently, a regular check of its semantic alignment is needed. To aid in the resolution of this semantic interoperability problem, the author proposes a framework that intends to provide generic solutions and a mean to validate the semantic consistency of ontologies in various scenarios, thus maintaining the interoperability state between the enrolled systems.

Full textThe use of Information and Communications Technology (ICTs) in healthcare has the potential of minimizing medical errors, reducing healthcare cost and improving collaboration between healthcare systems which can dramatically improve the healthcare service quality. However interoperability within different healthcare systems (clinics/hospitals/pharmacies) remains an issue of further research due to a lack of collaboration and exchange of healthcare information. To solve this problem, cross healthcare system collaboration is required. This paper proposes a conceptual semantic based healthcare collaboration framework based on Internet of Things (IoT) infrastructure that is able to offer a secure cross system information and knowledge exchange between different healthcare systems seamlessly that is readable by both machines and humans. In the proposed framework, an intelligent semantic gateway is introduced where a web application with restful Application Programming Interface (API) is used to expose the healthcare information of each system for collaboration. A case study that exposed the patient's data between two different healthcare systems was practically demonstrated where a pharmacist can access the patient's electronic prescription from the clinic.

Full textThe recent technological advances regarding the gathering and the sharing of geospatial data have made available important volume of geospatial data to potential users. Geospatial databases often represent the same geographical features but from different perspectives, and therefore, they are semantically heterogeneous. In order to support geospatial data sharing and collaboration between users of geospatial databases to achieve common goals, semantic heterogeneities must be resolved and users must have a shared understanding of the data being exchanged. That is, semantic interoperability of geospatial data must be achieved. At this time, numerous semantic interoperability approaches exist. However, the recent arrival and growing popularity of ad hoc networks has made the semantic interoperability problem more complex. Ad hoc networks of geospatial databases are network that self-organize for punctual needs and that do not rely on any predetermined structure. “Traditional” semantic interoperability approaches that were designed for two sources or for a limited static number of known sources are not suitable for ad hoc networks, which are dynamic and composed of a large number of autonomous sources. Nevertheless, while a semantic interoperability approach designed for ad hoc network should be scalable, it is essential to consider, when describing semantics of data, the particularities, the different contexts and the thematic, spatial and temporal aspects of geospatial data. In this thesis, a new approach for real time semantic interoperability in ad hoc network of geospatial databases that address the requirements posed by both geospatial databases and ad hoc networks is proposed. The main contributions of this approach for real time semantic interoperability are related to the dynamic collaboration among user agents of different geospatial databases, knowledge representation and extraction, automatic semantic mapping and semantic similarity, and query propagation in ad hoc network based on multi-agent theory. The conceptual framework that sets the foundation of the approach is based on principles of communication between agents in social network. Following the conceptual framework, this thesis proposes a new model for representing coalitions of geospatial databases that aim at supporting the collaboration among user agents of different geospatial databases of the network, in a semantic interoperability context. Based on that model, a new approach for discovering relevant sources and coalitions mining based on network analysis techniques is proposed. Operators for the management of events affecting coalitions are defined to manage real times changes occurring in the ad hoc network. Once coalitions are established, data exchanges inside a coalition or between different coalitions are possible only if the representation of semantics of rich enough, and the semantic reconciliation is achieved between ontologies describing the different geospatial databases. To achieve this goal, in this thesis we have defined a new representation model for concepts, the Multi-View Augmented Concept (MVAC). The role of this model is to enrich concepts of ontologies with their various contexts, the semantics of their spatiotemporal properties, and the dependencies between their features. A method to generate MVAC concept was developed. This method includes a method for the extraction of the different views of a concept that correspond to the different contexts, and an augmentation method based on association rule mining to extract dependencies between features. Then, two complementary models to resolve semantic heterogeneity between MVAC concepts were developed. First, a gradual automated semantic mapping model, the G-MAP, discovers qualitative semantic relations between MVAC concepts using rule-based reasoning engines that integrate new matching criteria. The ability of this model to take as input a rich and complex representation of concepts constitutes the contribution of this model with respect to existing ones. Second, we have developed Sim-Net, a Description Logic- based semantic similarity model adapted to ad hoc networks. The combination of both models supports an optimal interpretation by the user of the meaning of relations between concepts of different geospatial databases, improving semantic interoperability. The last component is a multi-strategy query propagation approach for ad hoc network. Strategies are formalized with the Lightweight Coordination Calculus (LCC), which support interactions between agents based on social norms and constraints in a distributed system, and they represent the different strategies employed to communicate in social networks. An algorithm for the real time adaptation of strategies to changes affecting the network is proposed. The approach was implemented with a prototype using the Java JXTA platform that simulates dynamic interaction between peers and groups of peers. The advantages, the usefulness and the feasibility of the approach were demonstrated with a disaster management scenario. An additional contribution is made in this thesis with the development of the new notion of semantic interoperability quality, and a framework to assess semantic interoperability quality. This framework was used to validate the approach. This new concept of semantic interoperability quality opens many new research perspectives with respect to the quality of data exchanges in network and its impact on decision-making.

Full textDue to the worldwide diversity of communities, a high number of ontologies representing the same segment of reality which are not semantically coincident have appeared. To solve this problem, a possible solution is to use a reference ontology to be the intermediary in the communications between the community enterprises and to outside. Since semantic mappings between enterprise‘s ontologies are established, this solution allows each of the enterprises to keep internally its own ontology and semantics unchanged. However information systems are not static, thus established mappings become obsoletes with time. This dissertation‘s objective is to identify a suitable method that combines semantic mappings with user‘s feedback, providing an automatic learning to ontologies & enabling auto-adaptability and dynamism to the information systems

IHE Cross Community Access (XCA)"
. XDS describes how to share EHRs in a community of healthcare enterprises and XCA describes how EHRs are shared across communities. However, currently no solution addresses some of the important challenges of cross community exchange environments. The first challenge is scalability. If every community joining the network needs to connect to every other community, this solution will not scale. Furthermore, each community may use a different coding vocabulary for the same metadata attribute in which case the target community cannot interpret the query involving such an attribute. Another important challenge is that each community has a different patient identifier domain. Querying for the patient identifiers in another community using patient demographic data may create patient privacy concerns. Yet another challenge in cross community EHR access is the EHR interoperability since the communities may be using different EHR content standards.

Full textToday Business Analytics is becoming increasingly popular and is utilized by organizations to analyze data that is used as support for decision-making. Business Analytics requires that interoperability exists between the data sources used to gather and compile data for analysis to ensure that data can be correctly interpreted. Therefore, the aim of this study is to investigate the possibility of creating an IT-artifact for querying several XML-documents consisting of various structures in order to achieve semantic interoperability, thus enabling Business Analytics. The structural differences considered in this report focuses on when XML-tags have been given different names that essentially have the same semantic meaning. The research strategy Design Science has been used when creating the solution. As a result of the research strategy the knowledge contribution is an IT-artifact. The IT-artifact is a Proof of concept that demonstrates a possible implementation of a solution that handles the semantic problems identified in this report. The result of the development is a flexible application that users can utilize to gather data from XML-files with different structures. This is made possible by letting the user create an ontology containing the tag names from the XML-files. By using ontologies like this we have given proof that it is possible to accomplish interoperability between XML-files with different structures. The conclusion that can be drawn from the development of the IT-artifact is that it is possible to create a general solution for the identified problem.
