摘要
我们提出了一个专为经济学文本应用而设计的经济词典(EL)。我们构建的词典有两个重要特点:(1) 广泛覆盖讨论经济概念的文档中使用的术语;(2) 在[-1, 1]范围内提供人工标注的情感评分。我们以一个简单的情感度量来说明 EL 的使用,并考虑了它在经济学中的一些应用。与其他词典的比较表明,EL 因其更广泛的领域相关术语覆盖面和更准确的词语情感分类而更胜一筹。
Sentiment analysis of economic text: A lexicon-based approach
We propose an economic lexicon (EL) specifically designed for textual applications in economics. We construct the dictionary with two important characteristics: (1) to have a wide coverage of terms used in documents discussing economic concepts, and (2) to provide a human-annotated sentiment score in the range [−1, 1]. We illustrate the use of the EL in the context of a simple sentiment measure and consider several applications in economics. The comparison to other lexicons shows that the EL is superior due to its wider coverage of domain relevant terms and its more accurate categorization of the word sentiment.
期刊介绍:
Published since 1962, (formerly Western Economic Journal), EI is widely regarded as one of the top scholarly journals in its field. Besides containing research on all economics topic areas, a principal objective is to make each article understandable to economists who are not necessarily specialists in the article topic area. Nine Nobel laureates are among EI long list of prestigious authors.
