              EFFICIENCY IN LARGE-SCALE PARSING SYSTEMS

                      a workshop to be held at

           Coling 2000, the 18th International Conference
                   on Computational Linguistics

                     Luxembourg, 5 August 2000

This workshop will focus on methods, grammars, and data to facilitate
empirical assessment and comparison of the efficiency of large-scale
parsing systems.

Workshop Scope and Aims

  Interest in large-scale, grammar-based parsing has recently seen a
  large increase, in response to the complexities of language-based
  application tasks such as speech-to-speech translation, and enabled by
  the availability of more powerful computational resources and by
  efforts in large-scale and collaborative grammar engineering.

  There are two main paradigms in the evaluation and comparison of the
  performance of parsing algorithms and implemented systems: (i) the
  formal, complexity-theoretic analysis of how an algorithm behaves,
  typically focussing on worst-case time and space complexity bounds;
  and (ii) the empirical study of how properties of the parser and input
  (possibly including the grammar used) affect actual, observed run-time
  efficiency.

  It has often been noted that the theoretical study of algorithms alone
  does not (yet) suffice to provide an accurate prediction about how a
  specific algorithm will perform in practice, when used in conjunction
  with a specific grammar (or type of grammar), and when applied to a
  particular domain and task.  Therefore, empirical assessment of
  practical parser performance has become an established technique and
  continues to be the primary means of comparison among algorithms.  At
  the same time, system competence (i.e. coverage and overgeneration
  with respect to a particular grammar and test set) cannot be decoupled
  from the evaluation of parser performance, because two algorithms can
  only be compared meaningfully when they really solve the same problem,
  i.e. either directly use the same grammar, or at least achieve
  demonstrably similar competence on the same test set.

  The focus of the workshop is on large-scale parsing systems and
  precise, comparable empirical assessment.  We envisage discussion at
  the workshop will centre on methods, reference grammars, and test data
  that will facilitate improved comparability.  The workshop is intended
  to bring together representatives from sites working on grammar-based
  parsing (both in academic and corporate environments) to help the
  field focus and converge on a common, pre-standard practice in
  empirical assessment of parsing systems.

  The organisers solicit contributions (in the form of extended
  abstracts; see below) on the following topics:

  - descriptions of grammars and data used to assess parser efficiency;
  - methods and tools for empirical assessment of parser efficiency; and
  - comparisons of the efficiency of different large-scale parsing
    systems.
