摘要
"isa"关系是知识获取中一种基本的语义关系,给出了中文"isa"关系的模式表示和获取方法。提出基于模式特征的种子选取算法和基于特征词的种子驱动的模式学习算法。实验说明了方法的有效性。
The ＂isa＂ relation is a basic semantic relation in knowledge acquisition.In this paper a seed-driven pattern representation and acquisition of ＂isa＂ relation from Chinese corpus is presented and an algorithm of seed acquisition based on pattern features and an algorithm of pattern learning based on feature words are presented.Experimental results demonstrate good performance of the method.
