| Abstract: | P-data(Packet data) model possessing dynamic characteristics was proposed for the first time by improving P-sets(Packet sets) model in the paper.It is composed of internal P-set(internal Packet data) and outer P-set(outer Packet data),and it is obtained by improving packet sets.P-data model and model structure were given in this paper.The attribute conjunctive normal form of P-data model was got.And then, the model of P-data reasoning and the intelligent acquisition theoryem of data were obtained. Finally,these concepts and results were applied to internal packet data intelligent acquisition and risk estimations. |
