npm install WNdb
WordNet is a large lexigraphical database of English words, including definitions, synonyms (aka, synsets), and part-of-speech data.  Now it has come to node.js through NaturalNode’s natural NLP module.  natural will download the WordNet files on first invocation.  But I found it more convenient to download the database off-line rather than on-demand.
So I’ve added the WordNet database files as an npm module. Â To install
npm install WNdb
This will install the complete WordNet 3.0 data files (about 34 MB uncompressed) and make them available to your program.
See npm registry and WNdb on github for more info.
