CLEF 2018 is the nineth CLEF conference continuing the popular CLEF campaigns which have run since 2000 contributing to the systematic evaluation of information access systems, primarily through experimentation on shared tasks.
Building on the format first introduced in 2010, CLEF 2018 consists of an independent peer-reviewed conference on a broad range of issues in the fields of multilingual and multimodal information access evaluation, and a set of labs and workshops designed to test different aspects of mono and cross-language Information retrieval systems. Together, the conference and the lab series will maintain and expand upon the CLEF tradition of community-based evaluation and discussion on evaluation issues.

CLEF 2018 is jointly organized by UAPV, AMU and Toulon University.
CLEF 2018 will be hosted by the University of Avignon, France, 10-14 September 2018.
