This workshop will provide a forum for researchers interested in the
development and evaluation of natural language grammars and parsing
systems, and in the creation of syntactically annotated reference

The aim of this workshop is to provide a forum for discussion of
evaluation methods for parsing systems, and proposals for the
development of syntactically annotated language resources.

With increased attention to evaluation of component technology in
language engineering, evaluation of parsing systems is rapidly becoming
a key issue. Numerous methods have been proposed and while one, the
Parseval/Penn Treebank scheme, has gained wide usage, this has to some
extent been due to the absence of workable alternatives rather than to
whole-hearted support. Parseval/PTB evaluation has several limitations
and drawbacks, including a commitment to a particular style of
grammatical analysis, and oversensitivity to certain innocuous types of
misanalysis while failing to penalise other common types of more serious
mistake. Also, the original published description of the scheme -- and
the evaluation software widely distributed as a follow-up to it -- is
specific to the English language. It may be that there are currently no
alternative more workable schemes or proposals, but this needs to be
more fully discussed: this workshop will provide an opportunity for such
a debate.

This workshop is particularly timely given the large number of CEC
Language Engineering projects that involve parsing in one form or
another and which need to evaluate and share the results of their
efforts. Parsing is an essential part of many larger applications, such
as Information Extraction, which have gained in importance over the last
few years. Often in such systems, the strength of the parser and
grammar has a direct effect on the desired results, and thus achieving
good results rests on being able to determine and improve weaknesses in
the parser/grammar. Without a reliable parser evaluation method this
cannot be done effectively.

A parsing evaluation workshop is also appropriate at this time given the
imminent creation of large-scale syntactically annotated resources for
European languages. Contributions from those involved in such activities
are welcomed, so as to improve communication between the resource
construction and the resource utilisation communities. This should
ensure that the resources constructed are maximally useful to the
general language engineering community.

The organisation of this workshop brings together two European language
engineering projects which are closely related and whose partners share
similar research interests: SPARKLE and ECRAN.

The organisers solicit contributions from the general community on the
following topics:

- descriptions of generic syntactic annotation schemes
- methodologies and metrics for parsing system evaluation
- reports and analyses of the results of utilising particular parser
 evaluation schemes
- description/analysis/experience of language-dependent (especially
 for languages other than English) and task-dependent syntactic
 annotation schemes

Subject: Language Resources and Evaluation


Adapting Lexical and Corpus Resources to Sublanguages and Applications
Granada May 26, 1998

This workshop will be held in conjunction with the First International
Conference on Language Resources and Evaluation (LREC), to be held
in Granada, Spain on May 28 - 30, 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.

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 providedwithout support for adaptation changes, whether caused
by language creativity and development or the shift to such
a previously unencountered domain.

The divergence of corpus usage's 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,
* staistical 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
