In this paper, we apply semantic web-based technologies to integrate heterogeneous data from medical information system, and design a heterogeneous data integration model, which combines Mediator/Wrapper framework with ontology, using OGSA-DAI as data accessing middleware. Mediator provides uniform query interface, decomposes user queries based on the mapping relations between global ontology and...
e-Business standards are recognised as one of the most important drivers of Business to Business Integration. These standards seek to provide unambiguous specifications for error-free exchange of documents and information between trading partners. These standards are however, syntax based and do not guarantee semantic interoperability between partners. This paper proposes the utilisation of semantic...
The role of metadata is gaining importance due to today's growth of multimedia content. Currently, XML is the standard for data interchange. However, as XML Schemas do not express semantics but rather the document structure, there is a lack of semantic interoperability regarding current (XML-based) metadata standards. By using semantic Web technologies, ontologies can be created to describe the semantics...
The use of autonomous agents in conjunction with semantic Web technologies such as extensible markup language (XML), resource description framework (RDF), Web services and ontologies will enhance the effectiveness of NATO network enabled capabilities (NNEC) operations. The semantic interoperability collaborative multi-agent architecture (Sl-CoMAr), incorporates semantic Web components, to address...
This paper describes an approach to software interoperability based on knowledge representation technologies developed in support of the emerging semantic Web. In particular, we are interested in the interoperation of an arbitrary set (two or more) of "legacy" applications that operate in a common domain, but that were not originally designed to support each other or to share information...
Managing multiple ontologies is now a core question in most of the applications that require semantic interoperability. The semantic Web is surely the most significant application of this report: the current challenge is not to design, develop and deploy domain ontologies but to define semantic correspondences among multiple ontologies covering overlapping domains. In this paper, we introduce a new...
The following topics are dealt with: XML; multimedia data mining and management; visual data analysis; multimedia indexing; evolutionary technique; knowledge management and discovery; ubiquitous context-aware and pervasive application; text-based information retrieval; software engineering; multimedia semantic Web and annotation; decision support system; structural health monitoring; flexible query...
Web services are an integral part of industry standards and they can act as a basis for semantic interoperability among the various distributed systems across the Web in order to achieve the concept of semantic Web. Multi agent systems also have their utilization in such areas for example in electronic commerce agent systems are already supporting the automation and semiautomation of information gathering...
Interoperability between different metadata schemas and data is an important issue for various semantic Web-related applications. The definitions and MPEG-7 data for multimedia content instances can't be used with other metadata standards in a semantically interoperable way. As part of an attempt to build a retrieval system that uses various metadata standards such as MPEG-7 and Dublin Core in a semantic...
