WordNet::QueryData provides a direct interface to the WordNet database files.
It requires the WordNet package. It allows the user direct access to the full
WordNet semantic lexicon. All parts of speech are supported and access is
generally very efficient because the index and morphical exclusion tables are
loaded at initialization. This initialization step is slow (appx. 10-15
seconds), but queries are very fast thereafter---thousands of queries can be
completed every second.
