Year: 1997

Type: conference-paper

Abstract: Dictionary methods for cross-language information retrieval give performance below that for mono-lingual retrieval.Failure to translate multi-term phrases has km shown to be one of the factors responsible for the errors associated with dictionary methods.First, we study the importance of phrasaI translation for this approach.Second, we explore the role of phrases in query expansion via local context analysis and local feedback and show how they can be used to significantly reduce the error associated with automatic dictionary translation.
