Abstract

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 Pn; if P1 then preferably P1,1 or ...; if P2 then preferably P2,1 or ...rdquo, where the Pipsilas 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.

数据库柔性查询中竞争条件模糊偏好的一种方法
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。
