An approach to multikey sequencing in an equiprobable keyterm retrieval situation
Barry G. T. Lowden · 1985
We present a simple generalised technique, for sequencing a multi-attribute file, which can be used in a situation where the query pattern is unknown and the term content equiprobable. The method is based on constructing a short spanning path through the records thereby minimising the sum of the Hamming distances between them. Retrieval performance is simulated over a range of query expressions and results suggest a significant reduction in the number of block accesses, using this technique, as compared with records randomly distributed over the file space.
