    Abstract
    The paper shows that the present evaluation methods in information retrieval (basically recall R and precision P and in some cases fallout F ) lack universal comparability in the sense that their values depend on the generality of the IR problem. A solution is given by using all "parts" of the database, including the non-relevant documents and also the not-retrieved documents. It turns out that the solution is given by introducing the measure M being the fraction of the not-retrieved documents that are relevant (hence the "miss" measure). We prove that - independent of the IR problem or of the IR action - the quadruple (P,R,F,M) belongs to a universal IR surface, being the same for all IR-activities. This universality is then exploited by defining a new measure for evaluation in IR allowing for unbiased comparisons of all IR results. We also show that only using one, two or even three measures from the set {P,R,F,M} necessary leads to evaluation measures that are non-universal and hence not capable of comparing different IR situations.

    Abstract
    Contemporary information systems, both the private and the commercially available ones, have often been blamed for their low effectiveness in terms of precision and recall, especially when they have reached considerable size with respect to file volume and use frequency (see, for example, Belkin, 1980; Blair, 1996, p.19; Desai, 1997; Drabenstott, 1996; Knorz, 1998). Saracevic (1989), after having reviewed the contemporary design of online subject access, calls "for radically different design principles and implementation" (p. 107). Van Rijsbergen (1990) writes: "The keywords approach with statistical techniques has reached its theoretical limit and further attempts for improvement are considered a waste of time" (p. 111). Lancaster (1992) deplores that very little really significant literature an subject indexing has been published in the last thirty or so years. In her preface to the Proceedings of the Sixth International Study Conference an Classification Research in 1997, Mcllwaine (1997) writes, "many were surprised to find that the problems with which they wrestle today are not greatly different from those that have been occupying the minds of specialists in the field for over a generation, and probably a great deal longer" (p. v).
