摘要/Abstract

摘要： P-集合（packet sets）具有动态特性，它是由内P-集合XF与外P-集合XF构成的集合对(XF,XF)。基于具有内动态特性的信息系统，应用内P-集合，提出(F,F-)-信息概念;讨论(F,F-)-信息的辨识与过滤。给出(F,F-)-粒度与(F,F-)-过滤系数概念，得到(F,F-)-信息辨识方法与辨识准则，以及(F,F-)-信息过滤定理与过滤准则，并给出(F,F-)-信息的辨识-过滤应用。(F,F-)-信息辨识与过滤的讨论结果为研究具有内动态现象的信息过滤-发现提供了一种新方法。

Abstract: P-sets （packet sets） has dynamic characteristic.It is a set pair (XF,XF) which is composed of internal P-sets XF and outer P-sets XF.Based on the information systems which are internal dynamic characteristic，the concept of (F,F-)-information is proposed by using the internal P-sets.Identification-filtration of (F,F-)-information are discussed.Meanwhile，the concepts of (F,F-)-granulation degree and (F,F-)-filtration coefficient are proposed.The identification method and criterion of (F,F-)-information，the filtration theorem and criterion of (F,F-)-information as well as the application about identification-filtration of (F,F-)-information are given.The results provide a new method for researching information filtration-discovery about internal dynamic phenomenon.

Key words: P-sets, (F, F-)-information, (F, F-)-granulation degree, (F, F-)-filtration coefficient, F-)-filtration coefficient
