ABSTRACT The experiments described here are part of a researchprogram whose objective is to develop a full-text The full-text retrieval design problem is largely a problem in the combination of statistical evidence. With this as its premise, the Berkeley group has concentrated on the challenge of finding a statistical methodology for combining retrieval clues in as powerful a way as possible, consistent with reasonable analytic and computational simplicity. Thus our research focus has been on the general logic of how to combine clues, with no attempt made at this stage to exploit as many clues as possible. We feel that if a straightforward statistical methodology can be found that extracts a maximum of retrieval power from a few good clues, and the methodology is clearly hospitable to the introduction of further clues in future, progress will have been made., |
