Subject:  CLEARS - educational and research tool for computational semantics
We want to introduce CLEARS, a freely available education and research
tool for computational semantics. From the feedback, we got so far
from initial presentations of CLEARS, we feel that this program might
be of interest for a wide audience.

   The CLEARS tool provides a graphical interface allowing
   interactive construction of semantic representations in a variety of
   different formalisms, and using several construction methods.
   CLEARS (Computational Linguistics Education and Research for Semantics)
   was developed as part of the FraCaS project which was designed to
   encourage convergence between different semantic formalisms,
   such as Montague-Grammar, DRT, and Situation Semantics.
   As a tutorial tool, CLEARS allows students to investigate
   various formalisms and their relationship. It can also be used
   to provide interactive demonstrations and to produce handouts.
   Because such a system has to be based largely on standard
   routines and algorithms that are fundamental for the area of
   computational semantics, a secondary aim of the project was
   to provide a set of well documented programs which could form
   the nucleus of a larger library of reusable code for this field.
   This also makes it relatively easy for students and researchers
   to add their own modules.
       - Interactive Graphical Environment allowing:
	   Step by Step Construction of Semantic Representations
	   Learning of Different Semantic Formalisms
       - High quality graphics for production of slides and handouts.
       - Extendible System to plug in new Formalisms
       - Allows Translation and Comparison between Formalisms
   (3) LIBRARY
       - Fundamental Algorithms for Computational Semantics
       - Reusable Modules for other Applications
       - Code to be maximally shared
       - No generalisation to the worst case.
       - Similarities between formalisms and algorithms made
	 explicit in the coding.
       a small selection:
	 Semantic formalisms
	     Lambda-DRT, Intensional & Extensional Montague Grammar
	     Situation Semantics, Classic (TopDown) DRT
	     DCG, Categorial Grammar,
	     FeatureBased Grammar
	     DCG, Chart Parser, Incremental Parser
   CLEARS is freely available. However you need
   -  SICSTUS Prolog 3  (unfortunately commercial)
   -  Tcl 7.4
   -  Tk  4.0            (both freely available)
   You can get CLEARS on the WWW from the following address, which
   contains further documentation:
   or you can download it via ftp from
   ftp ftp.coli.uni-sb.de  (
   cd /pub/fracas
   get CLEARS.tar.gz
   get README
   get userman.ps.gz
