Research on key technologies for the identification and tracking of negative network public opinions
At present,the tracking technology of network negative public opinion only completes the topic distinction based on keywords,without further research on the similarity of internal data,and the division process of sub-topics is too simple.In or-der to realize the accurate identification and tracking of negative public opinions,the key technology of identification and tracking of negative public opinions is studied.First,divide the sub-topics of negative network public opinion,analyze the similar character-istics of data objects,complete the clustering,and obtain a set of sub-topic clusters;second,identify negative network public opin-ion events,that is,dig and identify the essence of the event from the massive event information,infer the causality of the event,and predict the development trend;finally,realize the tracking of negative network public opinion topics.The experimental results show that the average misdetection rate of negative network public opinions is 1.1%and the average detection rate is 0.9%.The ex-perimental results can show that the method has high accuracy and reliability in the identification and tracking of negative network public opinions.
