                             Call for Papers

                            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.
