| Abstract: | It is difficult but important to realize recognition of hierarchical relationship during automatic thesaurus construction.Breaking through the limit of traditional method,word clustering based on se-mantic similarity can also recognize hierarchical words without this characters.This article introduce this method,and the test result shows it is feasible. |
