摘要
研究了信息抽取中的汉语实体关系提取技术,在使用模式匹配技术的基础上引入了词汇语义匹配技术对汉语实体关系进行提取。比较了一般模式匹配技术和词汇语义模式匹配技术在汉语实体关系提取任务中的性能。实验结果表明,一般模式匹配技术在处理中文时效果较差,而词汇语义模式匹配技术更适合于处理汉语实体关系提取任务。
The paper studies entity relation extraction of Chinese in information extraction. To extract Chinese entity relation, it imports technology of word semantic match into pattern match technology. Performance between general pattern match technology and semantic pattern match technology is compared. Experiment shows that general pattern match technology can＇t get acceptable result in task of Chinese, but new method presented by this paper is more adapted to deal with task of Chinese entity relation extraction.
