This book constitutes the thoroughly refereed post-proceedings of the Second Workshop of the Cross-Language Evaluation Forum, CLEF 2001, held in Darmstadt, Germany in September 2001. The 35 revised full papers presented together with two introductory survey articles and a comprehensive appendix were carefully improved during the round of reviewing and selections. The papers are organized in topical sections on systems evaluation experiments, mainly cross-language, monolingual experiments, interactive issues, and evaluation issues and results.
