Ontology-Driven Personalized Query Refinement

Sofia Stamou, Lefteris Kozanidis, Paraskevi Tzekou, Nikos Zotos
2009 Journal of Web Engineering  
Although refined queries may contribute to the improvement of retrieval results, nevertheless their realization is intrinsically limited in that they consider nothing about the preferences of the user  ...  Our experiments show that user preferences can be learnt accurately through the use of the topical ontology and refined queries based on the user preferences yield significant improvements in the search  ...  to improve retrieval efficiency.  ...
