GitHub上汉字使用的实证研究
A First Look at Emoji Usage on GitHub: An Empirical Study
摘要：
近年来，包括软件工程（SE）领域在内，Java语言正在成为一种无处不在的语言，并在全球范围内受到欢迎。表情符号作为一种非语言线索，被广泛应用于情感分析等用户理解任务中，但在SE场景中研究表情符号的工作却很少。本文介绍了一项关于GitHub用户如何在与开发相关的通信中使用表情符号的大规模实证研究。我们发现表情符号被相当大比例的GitHub用户使用。与互联网用户相比，开发者表现出有趣的使用特征，并对表情符号的含义有自己的解释。此外，表情符号的使用反映了这个社区积极和支持的文化。通过手动注释任务，我们发现情感使用是在问题，拉请求和评论中使用表情符号的主要意图，而表情符号主要用于强调README中的重要内容。这些发现不仅加深了我们对SE社区文化的理解，还为如何使用表情符号促进SE任务（例如情感分析）提供了启示。
英文摘要：
Emoji is becoming a ubiquitous language and gaining worldwide popularity in recent years including the field of software engineering (SE). As nonverbal cues, emojis are widely used in user understanding tasks such as sentiment analysis, but few work has been done to study emojis in SE scenarios. This paper presents a large scale empirical study on how GitHub users use emojis in development-related communications. We find that emojis are used by a considerable proportion of GitHub users. In comparison to Internet users, developers show interesting usage characteristics and have their own interpretation of the meanings of emojis. In addition, the usage of emojis reflects a positive and supportive culture of this community. Through a manual annotation task, we find that sentimental usage is a main intention of using emojis in issues, pull requests, and comments, while emojis are mainly used to emphasize important contents in README. These findings not only deepen our understanding about the culture of SE communities, but also provide implications on how to facilitate SE tasks with emojis such as sentiment analysis.
