摘要:

机器学习的最新进展已经导致行为类似于人类的计算机系统。情感分析,即自动确定文本中的情感,使我们能够利用商业、公共卫生、政府政策、社会科学和艺术中以前无法实现的大量机会。此外,从新闻到社交媒体帖子,对文本中的情感分析不仅提高了我们对人们如何通过语言传达情感的理解,而且也提高了我们对情感如何塑造我们行为的理解。本文对情感分析研究进行了全面的概述,包括:该领域的起源,任务的丰富景观,挑战,所使用的方法和资源的调查,以及应用程序。我们还讨论了如何,没有仔细的预先思考,情感分析有潜在的有害结果。我们概述了在情感分析中追求公平的最新研究路线。

英文摘要:

Recent advances in machine learning have led to computer systems that are human-like in behaviour. Sentiment analysis, the automatic determination of emotions in text, is allowing us to capitalize on substantial previously unattainable opportunities in commerce, public health, government policy, social sciences, and art. Further, analysis of emotions in text, from news to social media posts, is improving our understanding of not just how people convey emotions through language but also how emotions shape our behaviour. This article presents a sweeping overview of sentiment analysis research that includes: the origins of the field, the rich landscape of tasks, challenges, a survey of the methods and resources used, and applications. We also discuss discuss how, without careful fore-thought, sentiment analysis has the potential for harmful outcomes. We outline the latest lines of research in pursuit of fairness in sentiment analysis.
