摘要: The paper presents a new approach to database preference queries, where preferences are represented in possibilistic logic manner, using symbolic weights. weights may be processed without assessing their precise value, which leaves the freedom for user not specify any priority among preferences. also enforce (partial) ordering between them, if necessary. can related processing of fuzzy queries whose components conditionally weighted terms importance. In this paper, importance levels symbolically processed, and refinements both Pareto minimum used. representational power proposed setting is stressed, while compared with Best operator-like methods CP-net developed artificial intelligence. provides structured rather broad overview different lines research literature dealing handling queries.
