• Title: Manipulating emotions for ground truth emotion analysis
• Authors: Bennett Kleinberg
• Abstract summary: This paper introduces online emotion induction techniques from experimental behavioural research as a method for text-based emotion analysis. Text data were collected from participants who were randomly allocated to a happy, neutral or sad condition. We then examined how well lexicon approaches can retrieve the induced emotion.

• Abstract: Text data are being used as a lens through which human cognition can be studied at a large scale. Methods like emotion analysis are now in the standard toolkit of computational social scientists but typically rely on third-person annotation with unknown validity. As an alternative, this paper introduces online emotion induction techniques from experimental behavioural research as a method for text-based emotion analysis. Text data were collected from participants who were randomly allocated to a happy, neutral or sad condition. The findings support the mood induction procedure. We then examined how well lexicon approaches can retrieve the induced emotion. All approaches resulted in statistical differences between the true emotion conditions. Overall, only up to one-third of the variance in emotion was captured by text-based measurements. Pretrained classifiers performed poorly on detecting true emotions. The paper concludes with limitations and suggestions for future research.

  We investigate how well human-annotated emotion triggers correlate with features deemed salient in their prediction of emotions. Using EmoTrigger, we evaluate the ability of large language models to identify emotion triggers. Our analysis reveals that emotion triggers are largely not considered salient features for emotion prediction models, instead there is intricate interplay between various features and the task of emotion detection.

  We propose a novel formulation that measures the relative difference between the speech samples of different emotions. We then incorporate our formulation into a sequence-to-sequence emotional text-to-speech framework. At run-time, we control the model to produce the desired emotion mixture by manually defining an emotion attribute vector.

  In psychology, the class of emotion theories known as appraisal theories aims at explaining the link between events and emotions. We analyze the suitability of appraisal theories for emotion analysis in text with the goal of understanding if appraisal concepts can reliably be reconstructed by annotators. Our comparison of text classification methods to human annotators shows that both can reliably detect emotions and appraisals with similar performance.

  We propose a well-grounded circular-structured representation to utilize the prior knowledge for visual emotion distribution learning. To be specific, we first construct an Emotion Circle to unify any emotional state within it. On the proposed Emotion Circle, each emotion distribution is represented with an emotion vector, which is defined with three attributes.
