Abstract

In the CLEF 2005 Ad-Hoc Track we addressed the problem of retrieving information in morphologically rich languages, by experimenting with language-specific morphosyntactic processing and light Natural Language Processing (NLP). The diversity of the languages processed, namely Bulgarian, French, Italian, English, and Greek, allowed us to measure the effect of system-specific features upon the retrieval of these languages, and to juxtapose that effect to the role of language resources in Cross Language Information Retrieval (CLIR) in general.
