构建首个2万+英语多词表达焦虑关联词典，助力心理与语言研究。
From Trial by Fire To Sleep Like a Baby: A Lexicon of Anxiety Associations for 20k English Multiword Expressions
- 构建20,000+英语多词表达的焦虑关联词典，量化其情绪强度。
- 发现焦虑相关表达在二至四词序列中分布不均，三词表达最显著。
- 揭示多数焦虑关联具有组合性，适合心理学与NLP交叉研究者使用。
焦虑是对未来负面结果的不安感。近年来，学界日益关注焦虑与健康、身心及行为的关系，已有研究聚焦词汇与焦虑的关联资源。然而，针对更大文本单位如多词表达（MWE）的焦虑研究仍十分有限。本文首次构建大规模词典，涵盖超过20,000个英语多词表达的焦虑关联描述性规范数据。结果表明，该词典中焦虑关联具有高度可靠性。我们利用该词典分析不同类型的焦虑与平静相关表达的流行程度，并考察其在两词、三词和四词序列中的差异。同时探究多词表达的焦虑关联是否具有组合性（即由组成词决定）。该词典可广泛应用于心理学、自然语言处理、公共卫生与社会科学领域。词典已公开：https://saifmohammad.com/worrylex.html
原文摘要 · Abstract (English)
Anxiety is the unease about a possible future negative outcome. In recent years, there has been growing interest in understanding how anxiety relates to our health, well-being, body, mind, and behaviour. This includes work on lexical resources for word-anxiety association. However, there is very little anxiety-related work on larger units of text such as multiword expressions (MWE). Here, we introduce the first large-scale lexicon capturing descriptive norms of anxiety associations for more than 20k English MWEs. We show that the anxiety associations are highly reliable. We use the lexicon to study prevalence of different types of anxiety- and calmness-associated MWEs; and how that varies across two-, three-, and four-word sequences. We also study the extent to which the anxiety association of MWEs is compositional (due to its constituent words). The lexicon enables a wide variety of anxiety-related research in psychology, NLP, public health, and social sciences. The lexicon is freely available: https://saifmohammad.com/worrylex.html
