Abstract
Previous research on emotional language relied heavily on off-the-shelf sentiment dictionaries that only measure negative and positive tone. These dictionaries are often tailored to non-political domains and use bag-of-words approaches which come with a series of disadvantages. This paper creates and validates a (1) novel emotional dictionary specifically for political text and (2) word embedding models combined with neural-network classifiers that overcome limitations of the dictionary approach. Both tools can measure emotional appeals associated with eight discrete emotions. The different approaches are validated on 10,000 crowd-coded train ing sentences. The results highlight the strengths of word embeddings, but also important differences between both approaches. Furthermore, both approaches outperform widely used off-the-shelf dictionaries in measuring emotional language in German political communication.
