Automatic extraction method of domain ontology concepts based on dynamic weight multi-strategy
Zhang Huana · Computer Engineering and Applications Journal · 2014
To improve the automation degree and accuracy of Chinese domain ontology concept extraction, a method of concepts automatic extraction based on dynamic weighted multi-strategy integration is proposed. This paper filters out the candidate concepts according to the rule templates using automatic learning; and then improved DRDC, TF-IDF and NC-Value are integrated; it sequences the degree of domain membership of the candidate concept sets, and puts concepts whose weight exceeds the threshold value into final concept sets. After lots of experiments, the feasibility and validity of this method are proved.
