Cranfield project

The Cranfield experiments were computer information retrieval experiments conducted by Cyril W. Cleverdon at the College of Aeronautics at Cranfield in the 1960s, to evaluate the efficiency of indexing systems.

They represent the prototypical evaluation model of information retrieval systems, and this model has been used in large-scale information retrieval evaluation efforts such as the Text Retrieval Conference (TREC).
