Advances in Cross-Language Information Retrieval

This book presents the thoroughly refereed post-proceedings of a workshop by the Cross-Language Evaluation Forum Campaign, CLEF 2002, held in Rome, Italy in September 2002. The 43 revised full papers presented together with an introduction and run data in an appendix were carefully reviewed and revised upon presentation at the workshop. The papers are organized in topical sections on systems evaluation experiments, cross language and more, monolingual experiments, mainly domain-specific information retrieval, interactive issues, cross-language spoken document retrieval, and cross-language evaluation issues and initiatives.
