CLEF: ongoing activities and plans for the future

Multilingual information access and crosslanguage search and retrieval are key issues for digital libraries. For this reason, DELOS has continued to support the activities of the Cross-Language Evaluation Forum (CLEF), which has the promotion of research in multilingual information retrieval system development as its main goal. This paper describes the evolution of CLEF over the last seven years, illustrates the main results, and provides some recommendations for future work in this area.
