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 book on information
brokering discusses the next step in information interoperability
and integration. The emerging Internet economy based on burgeoning
B2B and B2C trading will 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 will 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.
Information Brokering Across Heterogeneous Digital Data's intended
readers are researchers, software architects and CTOs, advanced
product developers dealing with information intermediation issues
in the context of e-commerce (B2B and B2C), information technology
professionals in various vertical markets (e.g., geo-spatial
information, medicine, auto), and all librarians interested in
information brokering.
The Semantic Web is a vision - the idea of having data on the
Web defined and linked in such a way that it can be used by
machines not just for display purposes but for automation,
integration and reuse of data across various applications. However,
there is a widespread misconception that the Semantic Web is a
rehash of existing AI and database work. Kashyap, Bussler, and
Moran dispel this notion by presenting the multi-disciplinary
technological underpinnings such as machine learning, information
retrieval, service-oriented architectures, and grid computing. Thus
they combine the informational and computational aspects needed to
realize the full potential of the Semantic Web vision.
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.
The explosion in data exchange fostered by the success of the Web
has restated semantics as a kernel issue in the development of

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

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.

These are the proceedings of the 8th International Workshop on
Cooperative Information Agents (CIA 2004), held at the Fair and
Congress Center in - furt, Germany, September 27-29, 2004. It was
part of the multi-conference Net. ObjectDays 2004, and, in
particular, was co-located with the 2nd German Conference on
Multiagent Systems Technologies (MATES 2004). In today's networked
world of linked heterogeneous, pervasive computer systems, devices,
and information landscapes, the intelligent coordination and
provision of relevant added-value information at any time,
anywhere, by means of cooperative information agents becomes
increasingly important for a variety of applications. An
information agent is a computational software entity that has
access to one or multiple, heterogeneous, and geographically
dispersed data and information sources. It proactively searches for
and maintains information on behalf of its human users, or other
agents, preferably just in time. In other words,

overload in open, pervasive information and service landscapes.
Cooperative - formation agents may collaborate with each other to
accomplish both individual and shared joint goals depending on the
actual preferences of their users, b- getary constraints, and
resources available. One major challenge of developing agent-based
intelligent information systems in open environments is to balance
the autonomy of networked data, information, and knowledge sources
with the potential payo? of leveraging them using information
agents.
