Emotion Embeddings $\unicode{x2014}$ Learning Stable and Homogeneous Abstractions from Heterogeneous Affective Datasets

no code implementations15 Aug 2023 Sven Buechel, Udo Hahn

Human emotion is expressed in many communication modalities and media formats and so their computational study is equally diversified into natural language processing, audio signal analysis, computer vision, etc.

Empathic Conversations: A Multi-level Dataset of Contextualized Conversations

no code implementations25 May 2022 Damilola Omitaomu, Shabnam Tafreshi, Tingting Liu, Sven Buechel, Chris Callison-Burch, Johannes Eichstaedt, Lyle Ungar, João Sedoc

Hence, we collected detailed characterization of the participants' traits, their self-reported empathetic response to news articles, their conversational partner other-report, and turn-by-turn third-party assessments of the level of self-disclosure, emotion, and empathy expressed.

EmoBank: Studying the Impact of Annotation Perspective and Representation Format on Dimensional Emotion Analysis

1 code implementation EACL 2017 Sven Buechel, Udo Hahn

We describe EmoBank, a corpus of 10k English sentences balancing multiple genres, which we annotated with dimensional emotion metadata in the Valence-Arousal-Dominance (VAD) representation format.

Towards Label-Agnostic Emotion Embeddings

no code implementations EMNLP 2021 Sven Buechel, Luise Modersohn, Udo Hahn

Research in emotion analysis is scattered across different label formats (e. g., polarity types, basic emotion categories, and affective dimensions), linguistic levels (word vs. sentence vs. discourse), and, of course, (few well-resourced but much more under-resourced) natural languages and text genres (e. g., product reviews, tweets, news).

Learning and Evaluating Emotion Lexicons for 91 Languages

1 code implementation ACL 2020 Sven Buechel, Susanna Rücker, Udo Hahn

Emotion lexicons describe the affective meaning of words and thus constitute a centerpiece for advanced sentiment and emotion analysis.

Learning Word Ratings for Empathy and Distress from Document-Level User Responses

no code implementations LREC 2020 João Sedoc, Sven Buechel, Yehonathan Nachmany, Anneke Buffone, Lyle Ungar

The underlying problem of learning word ratings from higher-level supervision has to date only been addressed in an ad hoc fashion and has not used deep learning methods.

Clustering Emotion Recognition

Modeling Empathy and Distress in Reaction to News Stories

1 code implementation EMNLP 2018 Sven Buechel, Anneke Buffone, Barry Slaff, Lyle Ungar, João Sedoc

Computational detection and understanding of empathy is an important factor in advancing human-computer interaction.

JeSemE: Interleaving Semantics and Emotions in a Web Service for the Exploration of Language Change Phenomena

no code implementations COLING 2018 Johannes Hellrich, Sven Buechel, Udo Hahn

We here introduce a substantially extended version of JeSemE, an interactive website for visually exploring computationally derived time-variant information on word meanings and lexical emotions assembled from five large diachronic text corpora.

JeSemE: A Website for Exploring Diachronic Changes in Word Meaning and Emotion

2 code implementations11 Jul 2018 Johannes Hellrich, Sven Buechel, Udo Hahn

We here introduce a substantially extended version of JeSemE, an interactive website for visually exploring computationally derived time-variant information on word meanings and lexical emotions assembled from five large diachronic text corpora.

Representation Mapping: A Novel Approach to Generate High-Quality Multi-Lingual Emotion Lexicons

1 code implementation LREC 2018 Sven Buechel, Udo Hahn

In the past years, sentiment analysis has increasingly shifted attention to representational frameworks more expressive than semantic polarity (being positive, negative or neutral).

Sentiment Analysis

Emotion Representation Mapping for Automatic Lexicon Construction (Mostly) Performs on Human Level

1 code implementation COLING 2018 Sven Buechel, Udo Hahn

Emotion Representation Mapping (ERM) has the goal to convert existing emotion ratings from one representation format into another one, e. g., mapping Valence-Arousal-Dominance annotations for words or sentences into Ekman's Basic Emotions and vice versa.

Modeling Word Emotion in Historical Language: Quantity Beats Supposed Stability in Seed Word Selection

no code implementations WS 2019 Johannes Hellrich, Sven Buechel, Udo Hahn

To understand historical texts, we must be aware that language -- including the emotional connotation attached to words -- changes over time.

Readers vs. Writers vs. Texts: Coping with Different Perspectives of Text Understanding in Emotion Annotation

1 code implementation WS 2017 Sven Buechel, Udo Hahn

We here examine how different perspectives of understanding written discourse, like the reader{'}s, the writer{'}s or the text{'}s point of view, affect the quality of emotion annotations.

Feelings from the Past---Adapting Affective Lexicons for Historical Emotion Analysis

no code implementations WS 2016 Sven Buechel, Johannes Hellrich, Udo Hahn

We here describe a novel methodology for measuring affective language in historical text by expanding an affective lexicon and jointly adapting it to prior language stages.
