Castells, Pablo; Fernandez, Miriam; Vallet, David; Mylonas, Phivos and Avrithis, Yannis (2005). Self-tuning Personalized Information Retrieval in an Ontology-Based Framework. In: On the Move to Meaningful Internet Systems 2005: OTM 2005 Workshops, pp. 977–986.



Reliability is a well-known concern in the field of personalization technologies. We propose the extension of an ontology-based retrieval system with semantic-based personalization techniques, upon which automatic mechanisms are devised that dynamically gauge the degree of personalization, so as to benefit from adaptivity but yet reduce the risk of obtrusiveness and loss of user control. On the basis of a common domain ontology KB, the personalization framework represents, captures and exploits user preferences to bias search results towards personal user interests. Upon this, the intensity of personalization is automatically increased or decreased according to an assessment of the imprecision contained in user requests and system responses before personalization is applied.
