The focus of NLP research has been shifting towards semantic analysis from syntactic analysis. It has become evident that the methods employed for developing syntactic analyzers, i.e. supervised methods using small annotated corpora, are not the best methods for the semantic task. In order to handle semantics, we need large amounts of knowledge which may be best collected by semi/un- supervised methods from a huge unannotated corpus.

Many methods have already been proposed along this line of research, e.g. discovery of synonyms, hyponym-hypernyms, part-of relations, paraphrase, textual entailment, relations between things, relations between events and so on. The technical methods include distributional similarity, lexico-syntactic patterns, alignment and so on. Although such discovery techniques have been improving through numerous trials, there has been little discussion of the background and high-level picture of the field.

The objectives of this symposium will be to discuss the following topics:

  • High-level picture of the current technologies
  • The types of semantic knowledge we need
  • The relationships between knowledge and applications
  • The format for representing this knowledge and its re-use
  • Community effort for resource and platform
  • Possible directions for the technology in the future

The presentations will consist of invited talks by leaders in the field (shown below) and partially of general submissions. Presentations are expected to provide the speaker's high level position regarding the objectives described above.

General Submission

There are three categories for general submissions. Presentations are likely to be 15-20 minute talks. Posters or demos will be presented in a 2 hour slot. It is NOT necessary that the material be previously unpublished. We are expecting presentations giving an overview of the research at your site, or your top-level view of the topic, or a demo of a system related to the topic. Please send sekine cs.nyu.edu a one page description of your presentation (please indicate if it is a poster or demo). Deadline for submissions is September 30.

We are NOT planning to produce proceedings (i.e. you do NOT have to prepare papers), but we would like to produce a binder of the presentation slides for invited speakers and abstracts for general submissions, which may due about two weeks before the symposium.

Thank you very much for your interest; we are looking forward to see you at the symposium.
