摘要: 随着“互联网 + 旅游”模式的普及，网络中旅游信息呈爆炸式增长，其中用户评论由于数据的非结构特点及多样性，难以直接使用。本文通过挖掘用户评论对景区进行旅游评价，有利于游客和景区负责人多方面了解景点形象。本文以重庆市5家著名“AAAAA”级景区为研究对象，爬取12,571条评论数据。首先，借助LDA主题模型挖掘评论文本中的主题信息，并构建综合评价体系。然后，以游客对主题的关注程度为依据，对评价指标进行相应的赋权处理，得到评价得分。最后，对5家景区进行得分排序，并根据结果进行分析。从提取的主题信息来看，游客关注的五个主题为：平台服务、景区管理、自然景观、夏冬体验、性价比；从高到低，综合得分排序结果为：金佛山、武隆喀斯特、巫山小三峡、云阳龙岗、四面山。

This paper takes five famous “AAAAA” scenic spots in Chongqing as the research object, and crawls 12,571 comment data. Firstly, LDA topic model is used to mine the topic information in the comment text and construct a comprehensive evaluation system. Then, based on the tourists’ attention to the theme, the evaluation index is weighted accordingly, and the evaluation score is obtained. Finally, the five scenic spots are ranked and analyzed according to the results. From the extracted theme information, the five themes that tourists pay attention to are: platform service, scenic spot management, natural landscape, summer and winter experience, and cost performance.
