The ninth campaign of the Cross-Language Evaluation Forum (CLEF) for European languages was held from January to September 2008. There were seven main eval- tion tracks in CLEF 2008 plus two pilot tasks. The aim, as usual, was to test the p- formance of a wide range of multilingual information access (MLIA) systems or s- tem components. This year, 100 groups, mainly but not only from academia, parti- pated in the campaign. Most of the groups were from Europe but there was also a good contingent from North America and Asia plus a few participants from South America and Africa. Full details regarding the design of the tracks, the methodologies used for evaluation, and the results obtained by the participants can be found in the different sections of these proceedings. The results of the CLEF 2008 campaign were presented at a two-and-a-half day workshop held in Aarhus, Denmark, September 17–19, and attended by 150 resear- ers and system developers. The annual workshop, held in conjunction with the European Conference on Digital Libraries, plays an important role by providing the opportunity for all the groups that have participated in the evaluation campaign to get together comparing approaches and exchanging ideas. The schedule of the workshop was divided between plenary track overviews, and parallel, poster and breakout sessions presenting this year’s experiments and discu- ing ideas for the future. There were several invited talks.

Reseña del editor

This book constitutes the thoroughly refereed proceedings of the 9th Workshop of the Cross-Language Evaluation Forum, CLEF 2008, held in Aarhus, Denmark, in September 2008. The 130 revised and extended papers presented were carefully reviewed and selected for inclusion in the book. They are completed by an introduction on CLEF 2008. As usual, the seven main evaluation tracks in CLEF 2008 aimed to test the performance of a wide range of multilingual information access systems or system components. The papers are organized in topical main sections on Multilingual Textual Document Retrieval (Ad Hoc), Mono- and Cross-Language Scientific Data Retrieval (Domain-Specific), Interactive Cross-Language Retrieval (iCLEF), Multiple Language Question Answering (QA@CLEF), Cross-Language Retrieval in Image Collections (ImageCLEF), Multilingual Web Track (WebCLEF), Cross-Language Geographical Retrieval (GeoCLEF), Cross-Language Video Retrieval (VideoCLEF), Multilingual Information Filtering (INFILE@CLEF), and Morpho Challenge at CLEF 2008.
