Ambiguity and unknown term translation in CLIR

Zhou, Dong; Truran, Mark; Brailsford, Tim J

Abstract

In this paper we present a report on our participation in the CLEF Chinese-English ad hoc bilingual track, and we discuss a disambiguation strategy which employs a modified co-occurrence model to determine the most appropriate translation for a given query. This strategy is used alongside a pattern-based translation extraction method which addresses the ‘unknown term’ translation problem. Experimental results demonstrate that a combination of these two techniques substantially improves retrieval effectiveness when compared to various baseline systems that employ basic co-occurrence measures or make no provision for out-of-vocabulary terms.
