PHASES: A User Profile Learning Approach for Web Search
Adam Eckhardt, Tomáš Horváth, Peter Vojtáš · 2007
Web search heuristics based on Fagin's threshold algorithm assume we have the user profile in the form of particular attribute ordering and a fuzzy aggregation function representing the user combining function. Having these, there are sufficient algorithms for searching top-k answers. Finding particular attribute ordering and aggregation for a user still remains a problem. In this short paper our main contribution is a proof of concept of a new iterative process of acquisition of user preferences and attribute ordering .
