The Cranfield experiments were a series of experimental studies in information retrieval conducted by Cyril W. Cleverdon at the College of Aeronautics, today known as Cranfield University, in the 1960s to evaluate the efficiency of indexing systems. The experiments were broken into two main phases, neither of which was computerized. The entire collection of abstracts, resulting indexes and results were later distributed in electronic format and were widely used for decades.

| - The Cranfield experiments were a series of experimental studies in information retrieval conducted by Cyril W. Cleverdon at the College of Aeronautics, today known as Cranfield University, in the 1960s to evaluate the efficiency of indexing systems. The experiments were broken into two main phases, neither of which was computerized. The entire collection of abstracts, resulting indexes and results were later distributed in electronic format and were widely used for decades. In the first series of experiments, several existing indexing methods were compared to test their efficiency. The queries were generated by the authors of the papers in the collection and then translated into index lookups by experts in those systems. In this series, one method went from least efficient to most efficient after making minor changes to the arrangement of the way the data was recorded on the index cards. The conclusion appeared to be that the underlying methodology seemed less important than specific details of the implementation. This led to considerable debate on the methodology of the experiments. These criticisms also led to the second series of experiments, now known as Cranfield 2. Cranfield 2 attempted to gain additional insight by reversing the methodology; Cranfield 1 tested the ability for experts to find a specific resource following the index system, Cranfield 2 instead studied the results of asking human-language questions and seeing if the indexing system provided a relevant answer, regardless of whether it was the original target document. It too was the topic of considerable debate. The Cranfield experiments were extremely influential in the information retrieval field, itself a subject of considerable interest in the post-World War II era when the quantity of scientific research was exploding. It was the topic of continual debate for years and led to several computer projects to test its results. Its influence was considerable over a forty-year period before natural language indexes like those of modern web search engines became commonplace. (en)
- Proyecto CRANFIELD es el nombre como se conocen a los dos estudios de evaluación de sistemas de recuperación de información, dirigidos por Cyril Cleverdon entre los años 1957 y 1966, que sentaron las bases metodológicas de la disciplina Recuperación de información. Los estudios de evaluación comenzaron a llevarse a cabo en 1953, pero desde un ámbito filosófico y meramente especulativo. Cyril Cleverdon, trabajando en el College of Aeronautics de Cranfield (Cranfield Institute of Technology), diseñó un sistema de evaluación donde se proporcionaba un objeto de estudio, una metodología de investigación científica y un lenguaje terminológico.
