摘要

本文介绍了一种涉及偏好的新型数据库查询。我们的想法是将竞争性条件偏好子句结构为树形，其类型为ldp或…或Pn;如果P1，则优选P1,1或…;如果是P2，那么最好是P2,1或…Pipsilas不是排他性的(因此有了竞争的概念)。本文定义了这种查询的解释，并概述了从它遵循的评估技术。

An approach to competitive conditional fuzzy preferences in database flexible querying

This paper introduces a new type of database queries involving preferences. The idea is to consider competitive conditional preference clauses structured as a tree, of the type ldquopreferably P₁ or ... or P_n; if P₁ then preferably P_1,1 or ...; if P₂ then preferably P_2,1 or ...rdquo, where the P_ipsilas are not exclusive (thus the notion of competition). The paper defines the interpretation of such queries and outlines an evaluation technique that follows from it.
