Clairlib, The Clair Library

version 1.0 is now available

http://tangra.si.umich.edu/clair/clairlib

Introduction

The University of Michigan's CLAIR (Computational Linguistics And
Information Retrieval) group is happy to present version 1.0 of 
clairlib, the Clair library. 

The Clair library is intended to simplify a number of generic tasks in
Natural Language Processing (NLP), Information Retrieval (IR), and
Network Analysis. Its architecture also allows for external software
to be plugged in with very little effort.

Two distributions of the Clair library are available: Clairlib-core, 
with essential functionality and minimal dependence on external 
software, and Clairlib-ext, with extended functionality that may be 
of interest to a smaller audience.  Work is underway on Clairlib-bio 
and Clairlib-polisci, extensions that will be of interest to people 
working on Bioinformatics and Political Science.

Functionality

Native in Clairlib-core: Tokenization, Summarization, LexRank, 
Biased LexRank, Document Clustering, Document Indexing, PageRank, 
Biased PageRank, Web Graph Analysis, Network Generation*, Power 
Law Distribution Analysis*, Network Analysis* (clustering 
coefficient, degree distribution plotting, average shortest path, 
diameter, triangles, shortest path matrices, connected components), 
Cosine Similarity*, Random Walks on Graphs*, Statistics* 
(distributions, tests), Tf, Idf

Imported functionality into Clairlib-core: Stemming, Sentence 
Segmentation, Web Page Download, Web Crawling, XML Parsing*, 
XML Tree Building*, XML Writing* 

Clairlib-ext features: Sentence Segmentation using MxTerminator, 
Sentence Parsing using the Charniak Parser and Chunklink

* New and expanded functionality available for the first time in this
latest release.
