JWI (the MIT Java Wordnet Interface) is an easy-to-use, easy-to-extend Java library for interfacing with Wordnet. JWI supports access to Wordnet versions 1.6 through 3.0. Wordnet is a freely and publicly available semantic dictionary of English, developed under the direction of George Miller at Princeton University.

JWI is written for Java 1.5.0 and has the package namespace edu.mit.jwi. The distribution does not include the Wordnet dictionary files; these can be downloaded from the Wordnet download site. This version of software is distributed under a license that makes it free to use for non-commerical purposes, as long as proper copyright acknowledgement is made. If you are interested in obtaining a commercial license, please contact the MIT Technology Licensing Office.

The javadoc API is posted online for your convenience. So is the version changelog.

If you would like to receive an email when new versions are released, please subscribe to the extremely low-volume, moderated jwi-announce mailing list by sending an email to jwi-announce-request@lists.csail.mit.edu with subject 'subcribe'.
