基于Word2Vec的WordNet词语相似度计算研究

当前大部分WordNet词语相似度计算方法由于未充分考虑词语的语义信息和位置关系,导致相似度的准确率降低.为解决上述问题,提出了一种使用词向量模型Word2Vec计算WordNet词语相似度的新方法.在构建WordNet数据集时提出一种新形式,不再使用传统的文本语料库,同时提出信息位置排列方法对数据集加以处理.利用Wo...

Research on WordNet Word Similarity Calculation Based on Word2Vec

Currently, most WordNet word similarity calculation methods do not fully consider the semantic information and the location relationships of words, leading to the similarity accuracy reduction. To solve these problems, this paper proposes a new method to calculate the WordNet word similarity using the word vector model Word2Vec. A new form of the WordNet data set is proposed instead of using the traditional text corpus, and the information position arrangement method is used to process the data set. The vector representations are obtained by training the WordNet data set with the Word2Vec model. The word similarity calculation task is completed on the open word similarity evaluation sets like R&G-65, M&C-30 and MED38, and the Pearson correlation coefficient comparative experiment is conducted from multiple angels. Experimental results show that Pearson correlation coefficient computed by the similarity value calculated in this paper and the artificial judgement value is significantly improved.
