摘要
针对目前语义计算准确率低、可理解性差的问题,提出一种基于维基百科的语义相似度计算方法。不同于利用分类信息计算词的语义相似度,该方法利用页面的链接信息,通过模仿人类联想的方式计算不同词之间的相似度,所得到的结果较容易被理解,并结合词语的语义类别提高计算结果的准确率。和现有算法的对比实验证明了该方法的优越性。
Aiming at the low accuracy and poor intelligibility of current algorithms for semantic analysis,a semantic similarity computing method based on Wikipedia is proposed.Different from computing word＇s semantic similarity by category information,this method uses link information to calculate the similarity of different words in a way like human thinking.Result can be easily understood and the accuracy rate can be increased with semantic category.Experiment compared with current algorithms proves its advantage.
