COLE experiments at CLEF 2002 Spanish monolingual track
Miguel Á. Alonso, Francisco J. Ribadas, Jesús Vilares · CLEF (Working Notes) · 2002
In this our first participation in CLEF, we have applied Natural Language Processing techniques for single word and multi- word term conflation. We have tested several approaches at dif- ferent levels of text processing in our experiments: firstly, we have lemmatized the text to avoid inflectional variation; secondly, we have expanded the queries through synonyms according to a fixed threshold of similarity; thirdly, we have employed morphological families to deal with derivational variation; and fourthly, we have tested a mixed approach based on the employment of such families and syntactic dependencies to deal with the syntactic content of the document.
