This paper is concerned with the relation between selection power and selection labor for information retrieval. It is the first part of the development of a labor theoretic approach to information retrieval. Existing models for evaluation of information retrieval systems are reviewed and the distinction of operational from experimental systems partly dissolved. The often covert, but powerful, ...

designing an effective criterion for selecting the best rule is a major problem in theprocess of implementing fuzzy learning classifier (flc) systems. conventionally confidenceand support or combined measures of these are used as criteria for fuzzy rule evaluation. in thispaper new entities namely precision and recall from the field of information retrieval (ir)systems is adapted as alternative...
