摘要:

意见挖掘技术在商业智能、产品推荐、目标营销等领域的应用和使用引起了国内外学者的广泛关注。各种研究工作试图从不同粒度级别的客户评论中挖掘意见,包括单词,句子和文档级别。然而,开发一个全自动的意见挖掘和情感分析系统仍然是难以捉摸的。虽然意见挖掘和情感分析系统的发展势头越来越猛,但它们中的大多数都试图执行文档级的情感分析,将评论文档分类为积极的、消极的或中性的。这样的文档级意见挖掘方法无法提供关于用户对产品或服务的个体特征的情感的洞察。因此,如果评论可以在更细粒度的级别上进行处理,并通过一些视觉手段以摘要的形式呈现,突出产品的个人特征和用户对其表达的情感,似乎对客户和制造商都有很大的帮助。在本文中,一个统一的意见挖掘和情感分析框架的设计,提出了在机器学习和自然语言处理方法的交叉点。此外,提出了一种新的特征级审查摘要方案的设计,以可视化挖掘的功能,意见和他们的极性值在一个可理解的方式。

英文摘要:

The application and usage of opinion mining, especially for business intelligence, product recommendation, targeted marketing etc. have fascinated many research attentions around the globe. Various research efforts attempted to mine opinions from customer reviews at different levels of granularity, including word-, sentence-, and document-level. However, development of a fully automatic opinion mining and sentiment analysis system is still elusive. Though the development of opinion mining and sentiment analysis systems are getting momentum, most of them attempt to perform document-level sentiment analysis, classifying a review document as positive, negative, or neutral. Such document-level opinion mining approaches fail to provide insight about users sentiment on individual features of a product or service. Therefore, it seems to be a great help for both customers and manufacturers, if the reviews could be processed at a finer-grained level and presented in a summarized form through some visual means, highlighting individual features of a product and users sentiment expressed over them. In this paper, the design of a unified opinion mining and sentiment analysis framework is presented at the intersection of both machine learning and natural language processing approaches. Also, design of a novel feature-level review summarization scheme is proposed to visualize mined features, opinions and their polarity values in a comprehendible way.
