Clairlib, The Clair Library
is now available
http://tangra.si.umich.edu/clair/clairlib
INTRODUCTION
The University of Michigan's CLAIR (Computational Linguistics And
Information Retrieval) group (http://tangra.si.umich.edu/clair) is
happy to present the second release of clairlib, the Clair library.
The Clair library is written in Perl and is intended to simplify a
number of generic tasks in Natural Language Processing (NLP),
Information Retrieval (IR), and Lexical Network Analysis. Its
architecture also allows for external software to be plugged in with
very little effort.
Clairlib features a tiered architecture with a core shared by all
applications and subject-specific libraries (currently in political
science and bioinformatics).
