Description
Summary:The information retrieval process, treated strictly as a matching procedure, has the defects that the whole file must be probed for each query, and that it overlooks the fact that the relevance of the information from one document depends upon what is already known about the subject, and in turn affects the relevance of other documents subsequently examined. A mathematical model of a search technique in which the defects of the direct method are taken into account is demonstrated by an experiment in which a given paper is treated as an enquiry and the references cited in the paper are treated as relevant answers. The results in two tests show much better results than those achieved by the direct method. No spurious material was retrieved by either method.
