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.[1][2][3]

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). The evaluation model relies on three components: 1. a document collection (or corpus), 2. a set of queries, 3. a set of relevance judgements, i.e. a file which for each query lists the documents regarded as relevant to answer the given query. The format of the files can be found on the TREC website: https://trec.nist.gov/data/qrels_eng/.
