                   CALL FOR PAPERS

    Fifth Computational Natural Language Learning Workshop
              Toulouse, France, July 6-7, 2001



CoNLL is the yearly workshop organized by SIGNLL, the Association for
Computational Linguistics Special Interest Group on Natural Language
Learning ( Previous CoNLL meetings were
held in Madrid (1997), Sydney (1998), Bergen (1999) and Lisbon
(2000). The 2001 event will be held as a two-days workshop at the 39th
Annual Meeting of the Association for Computational Linguistics (ACL),
July 6-11, 2001 in Toulouse, France.

This year, a special theme will be the focus of the workshop:

    Interaction and Automation in Language Learning Resources

Apart from this special theme, the workshop will accept contributions
about language learning topics, including, but not limited to:

 - Computational models of human language acquisition
 - Computational models of the origins and evolution of language
 - Machine learning methods applied to natural language processing
   tasks (speech processing, phonology, morphology, syntax, semantics,
   discourse processing, language engineering applications)
 - Symbolic learning methods (Rule Induction and Decision Tree
   Learning, Lazy Learning,  Inductive Logic Programming, Analytical
   Learning, Transformation-based Error-driven Learning)
 - Biologically-inspired methods (Neural Networks, Evolutionary Computing)
 - Statistical methods (Bayesian Learning, HMM, maximum entropy, SNoW,
   Support  Vector Machines)
 - Reinforcement Learning
 - Active learning, ensemble methods, meta-learning
 - Computational Learning Theory analyses of language learning
 - Empirical and theoretical comparisons of language learning methods
 - Models of induction and analogy in Linguistics

This year's workshop will also accept submissions for a shared task
(segmenting a text into clauses-clausing).


Main Session Theme: Interaction and Automation in Language Learning

The purpose of the special theme is to present and discuss
state-of-the-art learning mechanisms for the automated acquisition of
language resources (dictionaries, ontologies, grammars) or the
automated adaptation of natural language resources/processors to new
domains or languages.

The dimensions of learning that are of interest for this session include:

- The integration of humans/linguists in the learning process
- The structure of the training data
- The kind of knowledge that is learned
- General study of learning methods that are suitable for natural
  language related tasks

Lately there have been new learning mechanisms that use either large
amounts of raw data or small sets of carefully constructed tagged
training samples. Learning language can be construed as learning
numbers or parameters for some statistical or symbolic system, or
learning rules assigning structures to input data (or a mix of
those). Learning can be done off-line, which introduces the problem of
interpreting (if needed) the derived knowledge before its use in an
NLP engine; or on-line, which raises user interaction
problems. Different approaches are tailored to solve different kinds
of problems subject to a different balance of requirements (large
vs. small training set, tagged vs. untagged training data, results
needs interpretation or can be used as is, etc.). While this session
aims at presenting the largest panorama of learning techniques, we
encourage submission of work on semi-automated learning techniques
that involve interaction with a human during the learning process or
the intervention of a linguist for interpreting results.

Special Session: Shared Task - Segmenting Text Into Clauses

We invite groups to take part in a shared task: Segmenting a Text Into
Clauses (Clausing).  Participating groups will be provided with the
same training and testing material, and will all use the same
evaluation criteria, thus allowing comparison between various learning
technologies.  After Chunking, the CoNLL-2000 shared task, Clausing
can be seen as the next step towards a full parsing.

More information on this shared task is available at:

Invited Session: Learning Computational Grammars

There will be a special session devoted to the presentation and
discussion of results of the EU Learning Computational Grammars
project (Coordinator: John Nerbonne). Project participants include:
the University of Groningen (The Netherlands, coordinator), University
of Antwerp (Belgium), the University of Tuebingen (Germany), SRI
Cambridge (UK), the University College Dublin (Ireland), the
University of Geneva (Switzerland), and Xerox Grenoble (France).

Invited Speaker (to be announced)


Format for Paper Submissions for Main Session

Submit an abstract of maximum 1500 words (Postscript or ASCII) by
April 6, 2001 electronically to the address below. Authors of accepted
abstracts will be invited to produce a full paper to be published in

Format For Shared Task Submissions

Submit an abstract of maximum 1500 words describing the learning
approach, and your results on the test set by April 6, 2001 to the
