Abstract

Demonstrates that a wide class of document retrieval systems induce natural topologies on their underlying document spaces and that different topologies can be induced on the same document space by 2 retrieval systems. Argues that this difference in topology reflects a meaningful difference in the performance of document retrieval systems. Compares the topological structures of the following document retrieval systems: vector space model, fuzzy set model, extended boolean model, probabilistic model, and the TIRS model (topological information retrieval system)
