WordNet

A Julia package for using Princeton's WordNet®, heavily inspired by Doches' rwordnet.

Simple Demo

db = DB()

WordNet.DB

sensekey(db, synsets(db, db['n', "cat"])[1], db['n', "cat"])

"cat%1:05:00::"

sensekeys(db, db['n', "cat"])

8-element Array{SubString{String},1}: "cat%1:05:00::" "cat%1:18:01::" "cat%1:18:00::" "cat%1:06:02::" "cat%1:06:00::" "cat%1:06:01::" "cat%1:05:02::" "cat%1:04:00::"

Design consideration

This package loads all of WordNet into memory. It's not terribly expensive, but it may not be suitable for all developers.

Wordnet Data

The constructor DB can optionally take a path to a WordNet directory, containing a dict folder. This should work for any release of WordNet. If you do not specify such a path, WordNet 3.0 will automatically be downloaded the first time you call DB(). It will only be downloaded once. See DataDeps.jl's readme for more information.
