摘要 针对在线中文评论中用户主观意见的不确定性,提出一种基于不确定理论的情感分析模型,并结合情感分析模型设计了个性化推荐算法。采用分词工具ICTCLAS和IKAnalyzer预处理在线中文评论,并基于情感词典(How Net)计算特征词的点互信息值;应用不确定变量与不确定集设计情感分析模型;根据情感分析模型设计新的最近邻居搜索方法并产生推荐。在两个真实数据集上进行试验,试验结果表明,该方法能够有效改进推荐结果的准确率,缓解数据稀疏问题。 Aiming at the uncertainty of users'subject opinions in online Chinese review,a sentiment analysis model was proposed based on uncertainty theory.An individual recommendation algorithm was designed on the basis of the proposed sentiment analysis model.Firstly,the tokenizers of ICTCLAS and IKAnalyzer were used to preprocess online Chinese review to generate characteristic words,and the point mutual information value of characteristic words accounting for the sentiment direction were computed based on sentiment dictionary(HowNet).Then,the sentiment analysis model was established via uncertainty theory of uncertain variable and uncertain set.In addition,the new similarity formula based on the proposed model was used to search the nearest neighbors.Finally,the recommendation lists were given.The experiments were carried out on two real datasets.The results showed that the proposed method could effectively improve the accuracy of recommendation and alleviate the sparse data problem.
