Abstract:

Based on P-sets and P-reasoning, notion of attribute conjunctive expansion-reduction of P-information (packet information), attribute conjunctive expansion-reduction characteristics and theorems of attribute conjunctive expansion-reduction are given. On the basis of internal P-reasoning and attribute conjunctive expansion, theorems of intelligent discovery of internal P-information are given.  According to P-reasoning and attribute conjunctive reduction, theorems of intelligent discovery and criterion of out P-information are given. To illustrate the theoretical result, applications of intelligent discovery of internal P-information possessed attribute conjunctive expansion are provided in information identification.

Key words: P-sets, attribute conjunctive, conjunctive expansion-reduction theorem, information identification, intelligent discovery of information, P-reasoning
