摘要:

姿态检测是情感分析的一个子问题,其中探索了一段自然语言文本的作者对于特定目标的姿态(在文本中明确地陈述或没有)。姿态输出通常为支持、反对或都不支持。在本文中,我们的目标是在体育相关的推文的立场检测,并提出了我们的基于SVM的立场分类器在这样的推文的性能结果。首先,我们描述了三个版本的专有推文数据集注释的立场信息,所有这些都是公开的研究目的。接下来,我们评估SVM分类器使用不同的功能集的立场检测这个数据集。所采用的功能是基于一元语法,二元语法,主题标签,外部链接,表情符号,最后,命名实体。结果表明,联合使用的功能的基础上unigrams,标签,命名实体的SVM分类器是一个合理的方法,立场检测问题的体育相关的推文。

英文摘要:

Stance detection is a subproblem of sentiment analysis where the stance of the author of a piece of natural language text for a particular target (either explicitly stated in the text or not) is explored. The stance output is usually given as Favor, Against, or Neither. In this paper, we target at stance detection on sports-related tweets and present the performance results of our SVM-based stance classifiers on such tweets. First, we describe three versions of our proprietary tweet data set annotated with stance information, all of which are made publicly available for research purposes. Next, we evaluate SVM classifiers using different feature sets for stance detection on this data set. The employed features are based on unigrams, bigrams, hashtags, external links, emoticons, and lastly, named entities. The results indicate that joint use of the features based on unigrams, hashtags, and named entities by SVM classifiers is a plausible approach for stance detection problem on sports-related tweets.
