Main GoalsMain Goals Producing an overview of current research and

development activities and an outline of main technical and scientific issues to be addressed in the near future in the form of a technical roadmap;

Demonstrating to industry how ontologies can be applied to particular problems in Knowledge Management, Enterprise Integration, and Electronic Commerce, and identifying problems in industry that can be addressed in scientific research;

Maintaining and extending information services for scientists, practitioners and students. Information services concern: scientific events and developments, courses, companies, and research institutions, material for research such as software and benchmarking problems;

Improving the co-operation with related scientific fields such as Software Agents, Web standards, Knowledge Engineering, Knowledge Representation, Information systems and database integration, and Information Retrieval;

Semantic Web – the full Semantic Web – the full potential Webpotential Web

• New & Next generation of the WebNew & Next generation of the Web:– Providing automated services based on

machine-processable semantics of data, reasoning techniques and heuristics that make use of these data;

– Interweaving computers and human beings;

Ontologies – Consensual Ontologies – Consensual UnderstandingUnderstanding

• The key asset for the Semantic Web– Ontologies: shared and common domain

theories; – They describe the semantics of a domain in a

human-understandable and computer-processable way

– A crucial role to enable content-based access, interoperability, and communication across the Web; Semantic Web = Knowledge WebSemantic Web = Knowledge Web

Knowledge ManagementKnowledge Management

Semantic Web & OntologiesSemantic Web & Ontologies: Turning information into useful knowledge; Harness corporate knowledge assets (maintaining and

finding the right information for companies at the right time and right place);

Secure company competition (efficiently release and reuse of knowledge);

Improve the understanding and smoothing the changing contextual knowledge;

Foster collaboration by capturing, representing and interpreting the knowledge resources of their organisations;

Current statusCurrent status: Company Intranet: Intellectual asset; Large information sources not well organised; Poor service (searching and analysing);

E-CommerceE-Commerce

Semantic Web & OntologiesSemantic Web & Ontologies:: Enable content-based access, interoperability,

integration information and communication. Facilitate finding, interrogating and exchanging

knowledge for B2B and B2C E-Commerce. Smooth the B2B or B2C marketplace friction (content

standard initiatives). Renovate the traditional business intelligence.

Current statusCurrent status: Competitiveness of companies depends on the products and services they offer; The ability to find, query and exchange knowledge is fundamental for B2B and B2C e-Commerce; Supplier and providers want to reach different customers, while customers want a large range of products at lower price;

Ontologies and agents in the Ontologies and agents in the Semantic WebSemantic Web

Using a combination of web pointers, web markup, and ontology languages, service descriptions can be enriched by including a machine-readable description of how the service runs and some explicit logic describing the consequences of using the service.

Web services ability to extend programs to more efficiently perform tasks for users with less human intervention.

Service descriptions + Service logics = Ontologies & Agents

Integrating ontologies & agents
