Ontology-based query refinement for XML information retrieval
Olfa Arfaoui, Minyar Sassi Hidri · 2016
The characteristics of XML (eXtensible Markup Language) documents have favored the need to develop specific and flexible querying systems while taking into account the coexistence of both structural and content information. The ultimate goal of these systems is to respond to different user expectations which tend to return appropriate answers to their preferences. However, people have often insufficient knowledge about XML data structure and contents, thus frequently obtaining empty answers or having to reformulate the queries several times. To solve this problem, we propose an ontology-based query refinement model for semi-structured information retrieval. It consists in reformulating a query by adding attributes from domain ontologies extracted from XML schemas.
