| 摘 要： | 该文提出一种基于句法规则和HowNet词典的商品评论细粒度观点分析方法,主要包括三个模块: 评价对象抽取、评价对象—评价词对抽取、评价对象总体观点得分计算。具体思路为: 首先,结合词性标注和频繁项集方法构建一个初始的评价对象词典,便于重用和修正商品的总体评价维度;其次,基于爬取的电商评论文本真实数据设计了评价对象—评价词对抽取规则;最后,借助HowNet词典分别计算不同评价维度的观点综合得分,进而对比同一商品不同品牌在各个维度下的总体观点评价,该方法在商品评论语料集上验证了有效性。 |

| Abstract: | This paper proposes a fine-grained opinion analysis model based on syntactic rules and HowNet for product reviews. The model consists of three main modules: the target mining, the target-opinion mining, and the overall opinion estimation. Firstly, a target lexicon is constructed in terms of part-of-speech tagging and frequent item set mining, which is convenient to reuse and modify the overall opinion target of products. Secondly, rules are designed for target-opinion extraction based on the real data of e-commerce reviews. Finally, HowNet dictionary is adopted to estimate the overall score of all targets, and then to compare different brands of the same product in each evaluation perspective. The validity of this method is verified on product review corpus. |
