Cranfield experiments: Background, Influence & Cranfield 1

The Cranfield experiments were a series of experimental studies in information retrieval conducted by Cyril W. Cleverdon in the 1960s at the College of Aeronautics, today known as Cranfield University, to evaluate the efficiency of indexing systems. The experiments were broken into two main phases, neither of which was computerized. The entire collection…
