A MULTIPLE TESTING OF THE ABC METHOD AND THE DEVELOPMENT OF A SECOND-GENERATION MODEL. PART II. TEST RESULTS AND AN ANALYSIS OF RECALL RATIO,

Abstract : After a brief summary of the test program, the statistical results tabulated as overall 'ABC-relevance ratios' and 'ABC-recall figures' are presented and reviewed. An abstract model developed in accordance with Max Weber's 'idealtypus' (Die Objektivitat sozial wissenschaftlicher und sozialpolitischer erkenntnis; in Gesammelte aufsatze zur wissenschaftslehre, 1922, pages 174, 179, 190-191, 194) is used in discussion such observations as the absence of an inverse relationship of relevance and recall ratios. The increase of recall in proportion to the number of documents located is attributed to the ABC-system's peculiar capability of making the user an integral part of the system. (Author)
