  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
arise:

  - 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.
