Abstract
Dictionary methods for cross-language information retrieval give performance below that for mono-lingual retrieval. Failure to translate multi-term phrases has been shown to be one of the factors responsible for the errors associated with dictionary methods. First, we study the importance of phrasal 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. 1 Introduction The development of IR systems for languages other than English has focused on building mono-lingual systems. Increased availability of on-line text in languages other than English and increased multi-national collaboration have motivated research in cross-language information retrieval (CLIR) - the development of systems to perform retrieval across languages. There have been three main approaches to CLIR: translation via machine t...
