			LREC 2002 Workshop
'Learning for Advanced HLT Applications: from Language Resources to
         2nd June 2002, Las Palmas, Canary Islands - Spain

Motivation and Aims

The application of Human Lamguage 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

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

- Theoretical and Practical aspects of adaptive Natural Language
- 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.
