Information intermediation is the foundation stone of some of the most successful Internet companies, and is perhaps second only to the Internet Infrastructure companies. On the heels of information integration and interoperability, this text on information brokering discusses the next step in information interoperability and integration. The emerging Internet economy based on burgeoning B2B and B2C trading may soon demand semantics-based information intermediation for its feasibility and success. B2B ventures are involved in the "rationalization" of new vertical markets and construction of domain specific product catalogs. This book provides approaches for re-use of existing vocabularies and domain ontologies as a basis for this rationalization and provides a framework based on inter-ontology interoperation. Infrastructural trade-offs that identify optimizations in performance and scalability of web sites may soon give way to information based trade-offs as alternate rationalization schemes come into play and the necessity of interoperating across these schemes is realized.

This book constitutes the refereed proceedings of the 8th International Workshop on Cooperative Information Agents, CIA 2004, held in Erfurt, Germany, in September 2004. The 18 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 59 submissions. The papers are organized in topical sections on information agents and p2p computing, issues of agent communication, recommender agents, information agents and mobile computing, industrial applications, and cooperation in open environments.

The explosion in data exchange fostered by the success of the Web has restated semantics as a kernel issue in the development of services providing data and - formationtousersandapplicationsworldwide.Thisnewlydesignatedconference serieson"SemanticsfortheNetworkedWorld"uni?esintoasingleframework the previous series on "Database Semantics" and "Visual Database Systems" that the IFIP WG 2.6 has been o?ering since 1985. Whereas the intent of the conferenceseriesistoexploreinterestingresearchissuesrelatedtosemantics,the themeforthe2004editionis"SemanticsforGridDatabases".Gridcomputing,a new ?eld concentrating on "?exible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources (also referred to as virtual organizations)", has gathered momentum in the context of providing shared infrastructures for large-scale scienti?c computations and data analysis. Similarly, P2P computing has attracted substantial attention. Currently, attention is devoted to the provision of middleware services to makecomputationalresourcesinteroperableatthetechnicallevelandtoincrease the e?ciency of use of physical resources.However, as Grid and P2P computing infrastructures are being increasingly adopted, they are likely to have typical problems of information overload that manifest themselves in any large-scale infrastructure for information and application sharing (e.g., the WWW). The need for resource discovery, application and service interoperability, integration and composition manifest themselves in these infrastructures. The ability to interoperate at the semantic level will largely determine the continued success and utilization of these infrastructures.

A decade ago Tim Berners-Lee proposed an extraordinary vision: despite the p- nomenal success of the Web, it would not, and could not, reach its full potential unless it became a place where automated processes could participate as well as people. This meant the publication of documents and data to the web in such a way that they could be interpreted, integrated, aggregated and queried to reveal new connections and answer questions, rather than just browsed and searched. Many scoffed at this idea, interpreting the early emphasis on language design and reas- ing as AI in new clothes. This missed the point. The Grand Challenge of the Semantic Web is one that needs not only the information structure of ontologies, metadata, and data, but also the computational infrastructure of Web Services, P2P and Grid distributed computing and workflows. Consequently, it is a truly who- system and multi-disciplinary effort. This is also an initiative that has to be put into practice. That means a pragmatic approach to standards, tools, mechanisms and methodologies, and real, challenging examples. It would seem self-evident that the Semantic Web should be able to make a major contribution to clinical information discovery. Scientific commu- ties are ideal incubators: knowledge-driven, fragmented, diverse, a range of str- tured and unstructured resources with many disconnected suppliers and consumers of knowledge. Moreover, the clinicians and biosciences have embraced the notions of annotation and classification using ontologies for centuries, and have dema- ing requirements for trust, security, fidelity and expressivity.
