| 摘 要： | 提出了一种新的词语相似度计算方法。该方法利用词语关联分布规范化因子,对互信息中目标词和基词的关联度度量方法进行了修正,通过计算目标词和基词的关联度,构造目标词的属性向量,由目标词的属性向量,利用夹角余弦法计算出目标词语相似度。实验结果验证了该方法的有效性。

| Abstract: | A new word similarity computation method was developed by using the link distribution relationship between words.This method enhances the performance of calculating correlation between base word and target word in mutual information,constructs the attribute vector of target word,and then uses the cosine method to calculate the similarity of target words.Simulation results show the validity of the method. |

| Keywords: | mutual information word link distribution word correlation word similarity |
