In this paper, the authors present a top-k approximate query system AQRR that can relax the original query and return the top-k query results for the autonomous Web database. The query relaxation and results ranking methods used in AQRR fully consider the original query, user preferences and data distribution. Experimental results demonstrated that the relevant query results can meet the user's needs and preferences effectively. In this paper: the authors present the main issues and key technologies of AQRR approach; they give an overview of the architecture of AQRR system and they show the demonstration of their AQRR system.
