On building a DyQE - A medical information system for exploring imprecise queries

Abstract

This paper sets out DyQE, a dynamic query expansion information retrieval system implemented in the medical domain, aimed at exploring imprecise queries. DyQE enhances standard query and result set navigation through integration with dynamic taxonomy and broad query expansion. The query expansion rules are sourced from a fine grained evaluation of data retrieval-based query expansion. DyQE offers both a concise representation of a broad subject area, and a wide variety of interesting links to related subject areas. © Springer-Verlag Berlin Heidelberg 2005.
