Abstract
The invention concerns quantitatively evaluating retrieval performance of retrieving systems that allow information retrieval when natural sentences are input as retrieval requests. Text and a title (heading) thereof are recognized as a pair of documents, and multiple documents individually having the texts and the headings are prepared as retrieval-target documents. In this, for example, each of the headings is used as contents of a retrieval request, and each of the texts is used as retrieval-target information. One of the headings is input to a retrieving device, and retrieving processing is performed, results of retrieval performed ranked for the headings according to the above, and retrieval-process evaluation is performed according to the ranks. The same processing is repeated for the following headings, and total retrieval processing is performed for the retrieving system according to the individual results of retrieval.
