Since the traditional retrieval performance measures, such as precision and recall, are not appropriate for retrieval with multilevel relevance measurement, a new performance measure is introduced, which is based on the preference relation between images.

Although so,the research on weakening completeness axiomof preference relation is hardly found in touchable references.

主要集中于对Von Neumann-Morgenstern的独立性公理假设和偏好关系传递性假设方面的弱化，比如不要求独立性和传递性等，从而使新的行为公理假设既能够满足实际中人们的选择行为，同时又能满足规范理论的要求。

But when their informationset is not complete,it is hard for decision-makers to determine,that is to say,the preference relation is not complete.

实际上，在一般决策问题中，决策人对备择方案的优劣判断主要依赖于决策人的信息集，而当决策人的信息集不完备时，决策人就可能难以对一些备择方案的优劣做出判断，这时完全性或连通性就不满足。

Without utility function, group preference relation on alternative set was constructed in this paper by means of efficient numbers of alternatives, which are described by Pareto efficient solutions of a group of multiobjective decision making problems respectively considered by decision makers.

本文撇开效用函数的介入，直接依据由各多目标决策问题的Pareto有效解表示的供选方案的有效数，引进了决策群体在供选方案集上的偏爱关系。
