| Abstract(in English) | Many web applications have been developed database-centric recently, especially in the e-commerce domain. Users of such applications often meet difficulties with expressing their intensions and resort to exploratory "trial-and-error" queries. Though the query composed is rigid enough, it may fail to return satisfactory number of results. In such cases, it may be better for the applications to produce approximate answers rather than enforcing users to relax or tighten the query constraints manually. This paper presents an approach to automatically reformulate queries based on user's feedback, in order to extract results that are likely to fulfill user's desires. First, initial query is reformulated into disjunctive form. The system then relaxes query condition on the key attirbute which represent each term in that disjunctive query. Finally, constraints on the other attributes are determined according to data distribution, to produce the final results. |
