Abstract
The problem of modifying retrieval system performance by utilizing user-provided feedback information is considered and some attending difficulties discussed. With a simple linear retrieval system as a model, the strategy of perturbing the system so as to satisfy the maximum number of respondents is found to lead to the formulation of a mixed integer-continuous variable programming problem with linear constraints and objective function. The importance of the ability to formulate reasonable and meaningful retrieval system goals as problems amenable to solution by known quantitative techniques is pointed out, and some discussion of computational feasibility and solution implementation is given.
