摘要
在扩展Petri网基础上提出了一种新的文本分类模型。基本思想是利用定性映射方法扩展Petri网系统,利用状态方程进行推理,使文本分类更接近于人类思维判断过程,并给出了分类算法。
Based on expanded Petri net basis,Petri net system is improved by qualitativea new text classification model is introduced. mapping, and state equation is the maininference techniques. The new text classification is closer to the thinking judgement process of operators. The text classification inference algorithm is provided in the end.
