Concept Hierarchy Induction Approach Based on Degree
Guozheng Yang · Journal of Chinese Computer Systems · 2010
By analyzing the characteristics and disadvantages of several Chinese ontology concept hierarchy induction methods,this paper proposes an induction method based on degree. Firstly the concept hierarchy relation is presented as a graph. Then the hierarchies of concepts are exploited with a reverse pruning algorithm. At last,after adding and pruning the concept relation the concept hierarchy is generated. Compared with variable value of parameter,the best performance,which is better than that of other methods,is reached when based on VSM but not using LSI.
