Hyponymy acquisition from Chinese text by SVM

Hyponymy as one of semantic relation taxonomies provides a fundamental knowledge for natural language processing applications. In this paper, we propose a method for automatically learning hyponymy terms by machine learning technique from text for Chinese. Our method relies on hand-crafted hyponymy patterns, and uses the syntactic features to build a multiple classifier to identify novel hyponymy pairs (hyponym /hypernym or hypernym /hyponym) in a sentence by SVM. Experimental results show that the method is effective in acquiring hyponymy from Chinese free text.
