| 摘要: |
| 针对目前缺乏多类型偏好共存的偏好逻辑系统的现状,提出并构造了一个能够描述和推理多种类型偏好的逻辑系统MPL(logic of many kinds of preference).在进一步提出MPL语言LMPL基于最粗糙/最细致描述原则的非单调语义基础上,通过分级知识库这种常用偏好表示方法的LMPL重写,初步考察了LMPL表示能力,最后进行总结并提出需要进一步研究解决的问题. |

| Abstract: |
| Presently,a whole logic system is still absent to represent and reason various kinds of preferences.In this paper,a preference logic MPL(logic of many kinds of preference)is introduced to supply the gap.In addition, recurring to the minimal/maximal specificity principle,a non-monotonic semantics of MPL's language LMPL is defined,and the application and capability of MPL are initially investigated by rewriting preferences expressed by ranked knowledge based into LMPL.Moreover,the conclusion and the prospective are presented in the end. |
