信息集推理研究

Studying on inference of information sets

目的研究2个信息集之间的关系。方法基于逻辑系统L,从语构角度出发,借助真度理论,将公式集合看作整体信息单位。结果在集族PF(S)上建立序关系,讨论了其上的代数性质,并定义了2个信息集之间的关联度和相似度。结论用信息集的关联度刻画出了信息集之间的关系,并用其解决了一个简单实际问题。

Purposes—To study the relationship between two information sets.Methods—Based on logic system L,the formula set is regarded as the whole information unit from the perspective of language construction and with the help of truth degree theory.Result—The order relation is established on PF(S),and its algebraic properties are discussed,with the correlation degree and similarity degree between two information sets are defined.Conclusion—The relation between information sets is characterized by the correlation degree,and a simple practical problem is solved by using it.
