Abstract

In this paper we present a description and evaluation of a pattern-based approach for definition extraction in Spanish specialised texts. The system is based on the search for definitional verbal patterns related to four different kinds of definitions: analytical, extensional, functional and synonimical. This system could be helpful in the development of ontologies, databases of lexical knowledge, glossaries or specialised dictionaries.
