Background and Introduction

Professor George Miller of the Cognitive Science Laboratory of Princeton University directed the development a lexicographic database called WordNet.

Princeton maintains a server by which the WordNet database can be browsed via the World Wide Web.

The WordNet database is implemented as a set of text files. Mark Nahabedian ([email protected]) has developed an interface to this database written in Common Lisp. This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

Some Exported Functions

A complete list can be found in packages.lisp with more documentation here.

wordnet

• synsets-containing-word/s
• get-synonyms
• get-antonyms
• synset-words
• part-of-speech
• cached-index-lookup
• index-entry-synsets

NOTE 1: A point of note is the part-of-speech. Arguments with this name can take the value :noun, :adjective, :verb or :adverb.

NOTE 2: I am not the author - these examples and explanations are all that I understand. There is more documentation available at the original repo - this is a forked one. Further, I have made part-of-speech as an optional argument in synsets-containing-word/s, and get-synonyms; the former function is named synsets-containing-words in the original repo.
