WordnetApi

API for Wordnet

WordnetAPI is a Java interface to the famous WordNet database of lexical relationships.

It converts the Wordnet Dictionary in an SQL Database (currently H2) and access the data through the Java Persistence API (currently Toplink), providing a stictly object-oriented interface, instead of the procedural one in the original Wordnet C library.

This is the domain model:

The access to entities happens with the DAO Pattern.

Examples of code usage

To look for a lemma in the dictionary:

WordnetDictionary dictionary = new WordnetDictionary();
String lemma = "conceptualization";
List<Word> result = dictionary.lookup(lemma);

In WordnetCLI the result is also formatted:

Given an inflected form, you can retrieve the base forms using the Wordnet's morphological processing. For example:

Morphy morphy = new Morphy();
String[] baseforms = morphy.stem("axes");

will be return "axis", "ax", "axe"
