Cross-Language Evaluation Forum (CLEF)
Since 2000 the Cross-Language Evaluation Forum (CLEF) has played a leading role in stimulating investigation and research in a wide range of key areas in the information retrieval domain, becoming well-known in the international IR community. It also promoted the study and implementation of appropriate evaluation methodologies for these diverse types of tasks and media. As a result a wide, strong, and multidisciplinary research community has been built, which covers and spans the different areas of expertise needed to deal with the spread of CLEF tracks and tasks. The results had traditionally been presented and discussed at annual workshops in conjunction with the European Conference for Digital Libraries.
