One of the key variables in the optimization of the retrieval process is the logic imposed on a set of query terms. If the query is small, a combinatorial algorithm can be employed to identify search expressions having an optimal logical form. An experiment is described in which this was done for queries expressed against MEDLINE, for a variety of criterion variables. The method employed is useful not only for assisting in identifying optimal logical forms, as demonstrated, but also as an experimental control device to assist investigations into the effects of varying the set, and number, of search terms. The experiment also suggests several novel properties of effective searching against MEDLINE, for example that searching with four MeSH terms is likely to be more successful than searching with a lesser number of terms, provided search logic is optimal. The latter result is, surprisingly, true for both Precision and Recall, i.e., a tradeoff between the maximally attainable values of these variables fails to hold when the number of search terms varies in this range.

The potential for using imaging technology in business applications is g r e a but in most businesses today imaging consists of facsimik communications and business gnaphic presentation. Factors besides hardware technology affect the implementation of image-based information systems; p r structural otganliation and retrieval mechanisms also contribute. This paper proposes a tawonomy as a comparison framewonk for the development of indaing technologies. It is proposed that image data represent a new f u n h e n t a l data type domain, &tinct from traditional numeric and character &ta types. The differentialion capability inherent to each of the three data types are developed in relation to their ertrinsic descriptive characteristics to describe indering methodologies. The advantages and limitations of these methodologies are investigated using this tawnomy, and directions for firture research are proposed.limiting: facilitating retried is a balancing act between specificity, for precision, and generalization, for recall 246 0073-1 129-1/92 $3.00 CP 1992 IEEE
