While preserving CLEF's traditional core business and goals, namely the benchmarking activities carried in various Tracks, these are complemented with a peer-reviewed conference component on experimental evaluation. The CLEF 2023 conferecnce aims at advancing research in the evaluation of complex information systems for cross-language tasks and scenarios, in order to support individuals, organizations, and communities who design, develop, employ, and improve such systems. Experimental evaluation - both laboratory and interactive - is a key to fostering the development of multilingual and multimodal information systems that address increasingly complex information needs.

Researchers and practitioners from all segments of the information access and related communities are invited to participate.

Conference proceedings wlll be published in Springer LNCS Series.
