摘要:

本文研究了用户对一个有争议的产品,即自动驾驶汽车的看法。为了找到人们对这项新技术的看法,我们使用了一个带注释的Twitter数据集,并使用一种称为主题建模的无监督概率模型提取了积极和消极推文中的主题。我们后来使用主题,以及语言学家和Twitter的特定功能来分类推文的情绪。关于意见,我们的分析结果表明,人们对未来技术感到乐观和兴奋,但同时他们认为它危险且不可靠。对于分类任务,我们发现Twitter的特定功能,如主题标签以及语言特征,如在分类推文的情感的顶级属性中的缩略词。

英文摘要:

This paper studies users' perception regarding a controversial product, namely self-driving (autonomous) cars. To find people's opinion regarding this new technology, we used an annotated Twitter dataset, and extracted the topics in positive and negative tweets using an unsupervised, probabilistic model known as topic modeling. We later used the topics, as well as linguist and Twitter specific features to classify the sentiment of the tweets. Regarding the opinions, the result of our analysis shows that people are optimistic and excited about the future technology, but at the same time they find it dangerous and not reliable. For the classification task, we found Twitter specific features, such as hashtags as well as linguistic features such as emphatic words among top attributes in classifying the sentiment of the tweets.
