Automatising the learning of lexical patterns: An application to the enrichment of WordNet by extracting semantic relationships from Wikipedia

by Maria Ruiz-Casado et al.

Ruiz-Casado et al. extend WordNet by extracting hyponym, hyperonym, holonym and meronym relations from the simple english version of WikiPedia. The authors automize

• the extraction of relations and
• the process of learning textual patterns modeling these relations (e.g. X is one of the PLURAL-NOUN in Y)

The described approach applies the following steps:

• word sense disambiguation
• pattern extraction based on existing relations in WordNet
• pattern generalization of the patterns retrieved in the step above
• identification of new relations

The authors show that the precision of the generated patterns is similar to patterns written by hand.
