摘要
手机的普及为生活带来便利,但由于品牌多、定位不同等导致消费者难以快速准确的选择合适的机型。为解决这个问题,提出了一种基于在线评论情感分析的手机推荐方法,用于帮助消费者寻找符合购买意愿的手机。首先,集成基础情感词典,构建程度副词、否定词、手机领域评论用语等相关词典,再根据消费者需求对手机各项参数进行多属性组合,并计算每条手机评论的情感值,将评论文本的情感模糊值转换为准确值,最后结合手机属性和评论的情感值定义特征矩阵,进而使用余弦相似度的方法得到top-k款与消费者需求相似的手机推荐给用户。对比传统的使用单一情感词典的推荐方法,结果表明该推荐方法能够有效的提高推荐结果的采纳度。
The popularity of mobile phones has brought convenience to life. But due to various brands and different positioning, it is difficult for consumers to quickly and accurately select the right model. In order to solve this problem, this paper proposes a recommendation method for mobile phone based on sentiment analysis of online reviews, which helps consumers find a mobile phone that meets their purchase intention. First, the basic sentiment dictionary is integrated to build related dictionaries such as degree adverbs, negative words and reviews terms in the field of mobile phone. Then, various parameters of the mobile phone are combined with multiple attributes according to the demand of consumer, and the sentiment value of each mobile phone reviews is calculated. The sentiment fuzzy value of the reviews text is converted into the accurate value. Finally, combine the mobile phone attributes and the sentiment value of the reviews to define the characteristic matrix, and then by using the method of cosine similarity get the top-k types mobile phone which is similar to the consumer's demand. The results show that this method can effectively help recommend the consumers purchasing mobile phones.
