我们提出了一个基于偏好排序的本体框架,允许用户在本体中明确可用的知识之间表达他们的偏好。使用这种形式,可以根据偏好对给定本体查询的答案进行排序,允许用户只检索最喜欢的答案。我们为这个框架中的主要计算任务提供了大量的复杂性结果,对于一般情况,以及作为底层本体语言的EL和DL-Lite核心。
We present an ontological framework, based on preference rankings, that allows users to express their preferences between the knowledge explicitly available in the ontology. Using this formalism, the answers for a given query to an ontology can be ranked by preference, allowing users to retrieve the most preferred answers only. We provide a host of complexity results for the main computational tasks in this framework, for the general case, and for EL and DL-Lite core as underlying ontology languages.
