CLEF 2018 was the nineth CLEF conference continuing the popular CLEF campaigns which have run since 2000 contributing to the systematicevaluation of information access systems, primarily through experimentation on shared tasks.
Building on the format first introduced in 2010, CLEF 2018 consisted 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 maintain and expand upon the CLEF tradition of community-based evaluation and discussion on evaluation issues.
Jointly organized by Avignon, Marseille and Toulon Universities, CLEF 2018 was hosted by the University of Avignon, France, 10-14 September 2018.
