论文摘要
情感分析（SA）是指统计，自然语言处理和计算语言学的十字路口的一系列技术。主要目标是检测书面文本中表达的个人意见和评论的语义取向。 SA在几个域中有几种实际应用。在教育背景下，这种方法的使用允许处理学生的反馈，旨在监视教师的教学效率并增强学习经验。本文希望回顾可用于进行SA，比较实现方法，讨论其特征并通过考虑简单示例的表现的不同R软件包。
Sentiment Analysis (SA) refers to a family of techniques at the crossroads of statistics, natural language processing, and computational linguistics. The primary goal is to detect the semantic orientation of individual opinions and comments expressed in written texts. There are several practical applications of SA in several domains. In an educational context, the use of this approach allows processing students' feedback, aiming at monitoring the teaching effectiveness of instructors and enhancing the learning experience. This paper wants to review the different R packages that can be used to carry on SA, comparing the implemented methods, discussing their characteristics, and showing how they perform by considering a simple example.
