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 Webers 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-systems peculiar capability of making the user an integral part of the system. Author
