COLE Experiments at CLEF 2003: Spanish Monolingual Track

In this our second participation in the CLEF Spanish monolingual track, we have continued applying Natural Language Processing techniques for single word and multi-word term conflation. Two different conflation approaches have been tested. The first approach is based on the lemmatization of the text in order to avoid inflectional variation. Our second approach consists of the employment of synt...

COLE Experiments in the CLEF 2002 Spanish Monolingual Track

In this our first participation in CLEF, we applied Natural Language Processing techniques for single word and multiword term conflation. We tested several approaches at different levels of text processing in our experiments: first, we lemmatized the text to avoid inflectional variation; second, we expanded the queries through synonyms according to a fixed similarity threshold; third, we employ...

COLE at CLEF 2004: Rapid Prototyping of a QA System for Spanish

This is our third participation in CLEF, this time in the Spanish monolingual Question Answering track. We have continued applying Natural Language Processing techniques for single word conflation. Our approach for Question Answering is based on complex pattern matching either over forms, part-of-speech tags or lemmas of the words involved.

EXETER at CLEF 2002: Experiments with Machine Translation for Monolingual and Bilingual Retrieval

This year, the University of Exeter participated in both the CLEF 2002 monolingual and bilingual task for two languages: Italian and Spanish. We submitted 4 ranked results each for both Italian and Spanish Monolingual tasks and 5 each for the bilingual tasks. We report experimental results from our investigations of merging topic translations from two machine translation (MT) systems and recent...
