Fuzzy Approaches to Flexible Querying in XML Retrieval

Abstract

In this paper we review some approaches to flexible querying in XML that apply several techniques among which Fuzzy Set Theory. In particular we focus on FleXy, a flexible extension of XQuery-FT that was developed as a library on the open source engine Base-X. We then present PatentLight, a tool for patent retrieval that was developed to show the expressive power of Flexy.
