Agent-Based Systems for Information Retrieval (http://www.aaai.org/Workshops/2002/ws-02.html) Our current climate is one of ever increasing amounts of information, and queries that require the intelligent integration of varied and potentially vast information sources. It is essential now more so than ever that we extend our abilities to search and exploit information both more accurately and more efficiently, and make connections readily between varied information sources. This goal is best achieved by leveraging the efforts of both the IR and agents communities. This workshop will focus on the application of agent-based and multi-agent system technology to the problems of storing and searching large collections of documents. This includes traditional information retrieval questions such as retrieval effectiveness and system performance. We also address agent-based approaches to distributed IR, where the agents (and documents) are scattered, for example, among the nodes of a network. Agent-based systems are also appropriate to the task of searching or even integrating heterogeneous sources of information, and the fusion of results. Topics We encourage submissions in the following areas: * Query formulation * Processing of standing/ad hoc queries * Use of ontologies in corpus selection * Metadata * Specialized protocols for distributed IR * Performance modeling and evaluation Participation will be limited to fifty individuals, by invitation. Submissions Those interested in participating should submit (to cost@acm.org ) either: (1) Brief statement of interest (one page), or (2) Complete paper (no more than eight pages) including keywords and authors' complete addresses. The deadline for submissions (set by AAAI) is March 15, 2002. Papers and statements of interest should be in PostScript, PDF, or HTML format. Direct all inquiries by email to the chair, R.
