| Abstract: | Aiming at the characteristics of the perspective sentence,knowledge rule was proposed that is suitable for perspective sentence identification.On this basis,we mixed the minimum cut principle of graph theory with machine learning classification method,introduced the concept of knowledge map,and proposed a algorithm of sentence recognition based on the knowledge map.In public evaluation corpus,self-builted corpora and open corpus,we conducted related experiment and the experimental results show that the perspective sentence classification performance and stability of the recognitioned algorithm based on the knowledge map have obvious advantages. |
