Class DBWordNet

java.lang.Object

javatools.database.DBWordNet

public class DBWordNet
extends java.lang.Object

This class is part of the Java Tools (see http://mpii.de/yago-naga/javatools). It is licensed under the Creative Commons Attribution License (see http://creativecommons.org/licenses/by/3.0) by the YAGO-NAGA team (see http://mpii.de/yago-naga). This class provides a wrapping for WordNet by a database. The database can be e.g. an OracleDatabase or a MySQLDatabase. Before creating instances of this class, you have to build the database by the construct-method. This method requires the Prolog-version of WordNet, which can be downloaded from the WordNet-website.
Example:

  // Execute this only once to create the database!
  Database database=new OracleDatabase("scott","tiger");
  DBWordNet.construct(database, new File("wordnet/prologversion"));
  
  // Use this code to access the data
  Database database=new OracleDatabase("scott","tiger");
  DBWordNet wordnet = new DBWordNet(database);
  System.out.println(wordnet.synsetsFor("house"));
  --->     103413667, 103413668, 103413669 (or similar)
  System.out.println(wordnet.glossFor(103413667));  
  --->     a dwelling that serves as living quarters for one or more families
