                           Call for participation

      Creating and Using Semantics for Information Retrieval and Filtering

                  State of the Art and Future Research

                   Las Palmas, Canary Islands - Spain
                            2nd of June 2002

                     Held in conjunction with the

    Third International Conference on Language Resources and Evaluation

                           (LREC 2002)

    The goal of this full day workshop is to bring together researchers
    in the domain of information management and extraction, and in particular,
    researchers concerned by the utility of enhancing queries with semantic
    information gleaned from languages resources and processes.

    Workshop scope and aims

    Several experiments have been carried out in the last 15 years
    investigating the use of various resources and techniques (e.g.,
    thesauri, synonyms, word sense disambiguation, etc.) to help refine or
    enhance queries. However, the conclusions drawn on the basis of these
    experiments vary widely. Results of some studies have led to the
    conclusion that semantic information serves no purpose and even
    degrades results, while others have concluded that the use of semantic
    information drawn from external resources significantly increases the
    performance of retrieval software. At this point, several question

      - Why do these conclusions vary so widely?
      - Is the divergence a result of differences in methodology?
      - Is the divergence a result of a difference in resources? What
        are the most suitable resources? Do results using manually
        constructed resources differ in significant ways from results
        using automatically extracted information?
      - From corpus building to terminology structuring, to which
        methodological requirements resources acquisition has to
        comply with in order to be relevant to a given application?
      - What is the contribution of specialized resources?
      - Are present frameworks for evaluation (e.g., TREC) appropriate
        for evaluation of results?.

    These questions are fundamental not only to research in document retrieval,
    but also for information searching, question answering, filtering, etc.
    Their importance is even more acute for multilingual applications, where,
    for instance, the question of whether to disambiguate before translating
    is fundamental.

    Moreover, the increasing diversity of monolingual as well as multilingual
    documents on the Web invite to focus attention on lexical variability in
    connection with textual genre and with questioning the resources
    reusability stance.

    The goal of this workshop is to bring together researchers in the domain
    of document retrieval, and in particular, researchers on both sides of the
    question of the utility of enhancing queries with semantic information
    gleaned from languages resources and processes.

    The workshop will provide a forum for presentation of the different points
    of view, followed by a roundtable in which the participants will assess the
    state of the art, consider the results of past and on-going work and the
    possible reasons for the considerable differences in their conclusions.
    Ultimately, they will attempt to identify future directions for research.
