Query Expansion on a Corporate Intranet: Using LSI to Increase Precision in Explorative Search

Overview Previous research has taught us that the typical nonprofessional information seeker on the World Wide Web submits very short queries resulting in low-precision results. It shows that this behaviour is repeated also by intranet users and therefore applies query expansion (QE) techniques to improve their search results. Arguing that casual searchers are likely to be unwilling to engage in the dialogue required for interactive QE, they provide an automatic QE system based on Latent Semantic Indexing (LSI).
