a workshop to be held at the
FIRST INTERNATIONAL CONFERENCE
ON LANGUAGE RESOURCES AND EVALUATION
GRANADA, SPAIN, 26 MAY 1998
The workshop will provide a forum for those researchers involved in
the development of methods to integrate corpora and MRDs, with the aim of
adding adaptive capabilities to existing linguistic resources.
Organisers: Roberto Basili (University of Roma "Tor Vergata"),
Roberta Catizone (University of Sheffield),
Maria Teresa Pazienza (University of Roma "Tor Vergata"),
Paola Velardi (University of Roma "La Sapienza),
Yorick Wilks (University of Sheffield)
WORKSHOP SCOPE AND AIMS
Lexicons, i.e., those components of a NLP system that contain "computable"
information about words, cannot be considered as static objects. Words may
behave very differently in different domains, and there are language
phenomena that do not generalize across sublanguages.
Lexicons are a snapshot of a given stage of development of a language,
normally provided without support for adaptation changes, whether caused
by language creativity and development or the shift to such
a previously unencountered domain.
The divergence of corpus usages from lexical norms has been studied
computationally at least since the late Sixties, but only recently
has the availability of large on-line corpora made it possible to establish
methods to cope systematically with this problem.
An emerging branch of research is now involved in studies and experiments
on corpus-driven linguistics, with the aim of complementing and
extending earlier work on lexicon acquisition based on Machine Readable
Dictionaries (MRD): data are extracted from texts, as embodiments of
language in
use, so as to capture lexical regularities and to code them into operational
forms. The purpose of this workshop will be to provide an updated snapshot
of current work in the area, and promote discussion of how to make progress.
Central topics will be (though this list is in no way exclusive):
* corpus-driven tuning of MRDs to optimize domain-specific inferences,
* terminology and jargon acquisition,
* sense extensions,
* acquisition of preference or subcategorization information from corpora
* taxonomy adaptation,
* statistical weighting of senses etc. to domains
* use of MRDs to provide explanations of linguistic phenomena in corpora
* what is the scope of "lexical tuning"
* the evaluation of lexical tuning as a separate task, or as part
of a more generic task
INDUSTRIAL PANEL ***NEW****
Automatic adaptation of lexicons to new domains through the use of application
corpora makes NLP applications more adaptable and portable.
The Program Commettee is organizing a joint panel to discuss this (and
other) issues
concerning next generation Information Extraction Systems.
The panel intends to bring industrial representatives to confront
expectations in IE from their viewpoint and degree of maturity of the
offering.
The following (and other) issues will be discussed:
- Is there a market for IE?
- What is the demand in domains such as New Services for the citizens,
Telecommunications, Management Support, etc?
- What are the technical requirements?Is the technology near to the market?
