Automatically maintained domain knowledge: Initial findings

Abstract

This paper explores the use of implicit user feedback in adapting the underlying domain model of an intranet search system. The domain model, a Formal Concept Analysis (FCA) lattice, is used as an interactive interface to allow user exploration of the context of an intranet query. Implicit user feedback is harnessed here to surmount the difficulty of achieving optimum document descriptors, essential for a browsable lattice. We present the results of a first user study of query refinements proposed by our adapted lattice. © Springer-Verlag Berlin Heidelberg 2009.
