			LREC 2002 Workshop

		'Learning for Advanced HLT Applications:
		 from Language Resources to Processes'

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


Motivation and Aims

The application of Human Language Technology to current IT trends
requires large amounts of specific linguistic resources. However,
existing large scale resources are never intended (i.e. designed and
handcrafted) for specific application tasks.

In order to bridge the existing gap, a variety of methods for
acquisition, adaptation and integration of linguistic resources have
been proposed in the NLP research area since the late 80's. Machine
learning and statistical techniques have been largely employed as
major devices able to deal with the scale and the complexity of the
problem. Although a large area of research, the impact of these
technologies on the applications is still low with respect to their
potential. Open problems are:

- the unclear targets of the learning activity: no general consensus
exists among the proposed approaches to the quality and quantity of
linguistic information needed for the different tasks (e.g. which is
the suitable representation that captures selective information from
the LR training material able to optimize parsing accuracy? Is it
fully grammatical, like in bracketed corpora, or lexical);

- the heterogeneity of sources: relevant information for the
adaptation task can be distributed in different repositories (lexical
knowledge bases and texts) or expressed differently (in different
languages and/or raw, e.g. texts, vs. semistructured data,
e.g. HTML/XML formats);

- the architectural idiosyncrasies: the proposed learning system makes
reference to different sources of information in different pipelined
(or redundant as in voting) application architectures.

- the application scope: current applications make a limited use (if
any) of available adaptation technologies. This often limits the scale
reachable by the current HLT aplications;

The above issues are orientative towards the complexity of the problem
in current research given the enormous potential of the application
field in areas like Web Mining, Question Answering and Knowledge
Management.

This workshop aims to bring together researchers of both academic and
industrial organizations interested in:

- Theoretical and Practical aspects of adaptive Natural Language
Processing
- Models of Acquisition and Integration of Domain Knowledge 
- Integration of induction models from heterogeneus data (lexicons vs.
ontologies, texts vs. HTML/XML pages)
- Learning Multlingual Information exploiting Multilingual Resources
(e.g. EuroWordnet)
- Theoretical and Practical aspects of Lexical Acquisition in
multilingual scenarios
- Architectures for learning, adaptation, and integration of LR
- Adaptive HLT applications (including but not limited to search,
retrieval, navigation and QA)
 
Papers are invited for presenting theoretical and methodological
aspects of Machine Learning of Natural Language as well as approaches
making effective use of adaptive methods in the perspective of
pre-industrial or industrial applications.

 CALL FOR PAPERS

 PorTAL - PORTUGAL for NATURAL LANGUAGE PROCESSING

 Faro, Portugal

 June 23rd-26th, 2002


 URL: http://label.ist.utl.pt/portal


PorTAL - PORTUGAL for NATURAL LANGUAGE PROCESSING will be held at FARO
(Algarve, Portugal), in June 23-26, 2002. PorTAL follows the FracTAL
conference, held in Besanon (France), December 1997, and VexTAL
held in Venice (Italy), November 1999.


SCOPE OF THE CONFERENCE

Papers are invited on substantial, original, and unpublished research
on all aspects of natural language processing related areas,
including, but not limited to:

 * spoken and written language analysis and generation;
 * pragmatics, discourse, semantics, syntax, morphology and
 lexical acquisition;
 * linguistic, mathematical, and psychological models of
 language;
 * language-oriented information retrieval and information
 extraction;
 * knowledge acquisition;
 * corpus-based and statistical language modelling;
 * machine translation and translation aids;
 * natural language interfaces and dialogue systems;
 * message and narrative understanding systems;
 * computational lexicography;
 * Internet applications;
 * evaluation of systems.

We welcome submissions on any topic that is of interest to the NLP
community, but we particularly encourage submissions that broaden the
scope of our community through the consideration of practical NLP
applications. We also invite people from industry working on NLP to
send us their submissions and offer an opportunity to discuss and
demonstrate their latest applications.
