Call for Papers


We define Natural Language based Knowledge Representation as a
representation that is closer to NL as opposed to being more
artificial.  The intuition is that such representations will be more
expressive, or at least borrow as much as possible from the
expressiveness of NL.

The goal of this Special Track is to re-assess the status of Natural
Language (NL) based Knowledge Representations (KR) and systems. It was
believed that NL-based KR systems would deliver representational and
inferential properties of natural language but the hard issues in NL
such as ambiguity, context-dependency and the complexity of syntax,
semantics and pragmatics limited in the past the progress of building
promising knowledge processing systems.

Among the advantages of building NL-based KR systems are:

   1. NL-based systems would be user friendly
   2. Most human knowledge is encoded and transmitted via natural
      language and thus NL-based KR are a natural development
   3. searching on the Internet has become a necessity and a daily task
      for most of us; natural language is heavily used in this task
      since more than 90% of the web information is textual
   4. NL-based knowledge processing sytems would provide a uniform
      symbolic representation for encoding knowledge and processing it
   5. it is hard to match expressiveness and precision of natural
      language, particularly in not (well) formalized domains

Recent advances of Natural Language Processing (NLP) in the areas of
syntactic parsing, semantics and pragmatics have opened new
perspectives for developing expressive KR and building promising
NL-based knowledge processing systems. A special track to re-assess
the new perspectives is needed and this Special Track aims to satisfy
this need.


We invite highly original papers that describe:

   1. novel, expressive NL-based representations
   2. multi-level representations
   3. NL-based inference methods and reasoning engines
   4. evaluation techniques for NL-based KR
   5. challenges in NL-based representations and in deriving such
      representations from NL texts, especially how recent advances in
      NL technologies provide new opportunities for knowledge aquisition
      and processing
   6. techniques for coreference resolution, word sense disambiguation,
      information extraction, predicate-argument structure, frame
      semantics, preposition semantics, syntactic parsing, named entity
      recognition, etc. and their impact on NL-based KR
   7. NL-based KR in dialogue management
   8. NL-based KR in Question/Query Answering
   9. NL-based KR in auto tutoring systems
  10. NL-based KR in Information Retrieval
  11. large knowledge bases construction using NL-based KR
  12. scalability issues of systems built using NL-based KR
  13. other related issues

Submission Guidelines

Interested authors should format their papers according to AAAI
formatting guidelines. The papers should not exceed 6 pages and are due
by October 22, 2004. Please note the change from 5 to 6 pages from the
first CFP. Additional pages (7 and more) have to be cleared by the
program chairs and will be $100 each. The papers should not identify the
author(s) in any manner. Authors should indicate the special track if
one exists that closely matches the topic of their paper. All
submissions will be done electronically via the FLAIRS web submission
system available through the paper submission site at

Conference Proceedings

Papers will be refereed and all accepted papers will appear in the
conference proceedings which will be published by AAAI Press.
Selected authors will be invited to submit extended versions of their
papers to a special issue of the International Journal on Artificial
Intelligence Tools (IJAIT) to be published in 2006.
