About CLEF (Cross-Language Education and Function)

The CLEF (Cross-Language Education and Function) is a free online resource on topics and subjects related to cross language information retrieval. Our goal is to present the importance of information retrieval in two or multiple languages, how it’s done, and frequently encountered challenges and obstacles as well as how to overcome them.

But we also seek to provide access to information relevant for the actual user and help the general public understand major sub-fields and strategies including mono-, bi- and multilingual information retrieval, most commonly used cross-language techniques, interactive cross-language retrieval and more.
