Considering the problem of unified description of data modeling languages for computer network management, information specification ontology may be a prospective solution. However, basics of a unified mathematical theory are still lacking for ontology building. Delighted by the philosophical thinking of conceptual scheme for descriptive metaphysics, this paper tries to utilize formal concept analysis...
This paper proposed an approach to describe and manage the e-learning resources. The learning resources is firstly described in XML format using the share content object reference model standard, then the binding XML file and learning resource content is produced. Secondly, the described learning resources are put into the database and management according to the content package specification and...
Complications related to volume increase of data that needs to be analyzed, lack or insufficiency of complementary metadata and task of transforming data to ontologies in this context are described. Applications with declarative approach for solving task of transforming arbitrary located data in any available format to ontological representation are examined. Relevant languages and technologies are...
An example is given to analyze its security flaws and security requirements in the services oriented architecture. Aimed at the increasingly severe security of SOA, a model for building end to end security services is proposed, the specification concerned with Web services message-level security is put forward, such as WS-security and SAML, according to these specifications, the design and realization...
Every year more than 250000 people suffer from cardiac arrest in Europe. Survival rate to hospital discharge vary in the range 1.8-30.7%, indicating a potential for improvement by identifying explanatory factors. Ambulance charts documenting resuscitation efforts may be a natural starting point for such analysis, but data subject to analysis have to be comparable. Different data formats make common...
Leveraging the use of semantic engineering information to improve interoperability of IT systems in sustainable manufacturing is the focus of this paper. It proposes an ontology-driven approach to formalization and representation of engineering semantics to support meaningful communication and interoperation in sustainable manufacturing and service systems. The paper argues that the development of...
This paper presents a framework for automatically structuring knowledge, in order to reveal the intrinsic relationships among data. The approach exploits a fuzzy extension of Formal Concept Analysis theory, applied to RSS feeds. On the basis of the RSS Feed content, fuzzy FCA generates an ontology oriented knowledge network, enabling the accessibility of web resources presented by feeds. The framework...
Product design chain management has become more important for enterprise to develop innovative product within a shorter lead-time, it's more complex challenge than supply chain collaboration, information share with partners is a vital important to success for collaborative design. This paper focuses on modeling of information integration among partnerships, combination of semantic Web and Web services,...
Topic Maps (TM) are standardized by ISO 13250 for the purpose of semantic annotation of WWW resources. XML Topic Maps (XTM) is straightforwardly usable over the Internet and support a wide variety of applications. This paper presents the knowledge navigation system for city information portal based on XML Topic Maps technology, including four layers: information resources layer, knowledge layer, information...
The lack of semantics in Web services description language (WSDL) prevents automatic discovery and hence automatic invocation and composition. In our work, we are interested in extending existing approaches for the description of semantic Web services. Previously, we have extended the W3C recommendation on semantics for Web services (SAWSDL) and have proposed the use of two types of ontologies: a...
Semantic Business Process Management is a recent and promising research area devoted to extending the results from Semantic Web Services - i.e., the application of ontology-based modelling and reasoning to Web Services - to Business Process Management, which is these days often realised using Service-Oriented Architectures. One important task for Semantic Business Process Management is the addition...
In a previous work we presented an approach to allow invocation of services whose interface and behavior differ from each other. Such approach requires the definition of scripts by some human being able to completely understand the mismatches and properly combine the mapping functions. Furthermore, such approach requires an intensive effort from a system integrator that, in the worst case in which...
Date sources integration is one of the major challenges for nowadays enterprise information system. Indeed, because of growing heterogeneous systems, access to information is more and more complex. In this context, we have implemented a prototype of WASSIT, a data integration system based on mediation-adaptation architecture. This paper briefly describes the meta-model ontology used in the integration...
The XML standard adopted for the interoperability among Web services had played prominent role in enhancing systems/application integration and also facilitates linking up clientpsilas demands through loosely couple platform. However, the use of this technology has a major disadvantage of lacking in semantic representations of the contents in the Web and makes the service discovery scheme of the UDDI...
Sensor observation service (SOS) is a Web service specification defined by the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) group in order to standardize the way sensors and sensor data are discovered and accessed on the Web. This standard goes a long way in providing interoperability between repositories of heterogeneous sensor data and applications that use this data. Many of these...
As more and more data is available through the Web, mediation of information from multiple autonomous and heterogeneous data sources becomes a crucial task for future Web information systems. We describe the features of our mediation framework WASSIT (frameWork d'integrAtion de reSSources de donnees par la medIaTion), which provides the user with an integrated view of the underlying data sources....
News production is characterized by complex and dynamic workflows in which it is important to produce and distribute news items as fast as possible. In this paper, we show how personalized distribution and consumption of news items can be enabled by automatically enriching news metadata with open linked datasets available on the web of data, thus providing a more pleasant experience to fastidious...
In order to use the multimedia sources efficiently, finding the semantic content behind the resources and analyzing them, a framework to uniformly describe multimedia resources is used in this paper by using the theory of ontology. Based on fifteen elementary metadata of Dublin Core Metadata Element Set, the notion of the Basic Metadata and Expand Metadata are defined to realize the unify description...
This paper presents an approach for comparing two architectures for ontology-based semantic annotation for service interoperability, the EMPOWER architecture using platform specific XML-based technologies and the MEMPOWER architecture extending this with platform independent model driven architecture (MDA) based technologies. We will compare the two architectures with respect to pilot requirements...
The paper is to solve how to map OWL information model to database which is very important for sharing information. First, relatively complete and exact mapping rules with the consideration of OWL syntax and semantics is designed. Then, the mapping system from OWL to relational database is implemented based on Jena using Java. Finally, the mapping system is tested by some OWL examples. The mapping...
