Challenge: Anomalies in discourse are induced or acted by a machine learning algorithm.
Approach: They propose to use facial and speech video to create a corpus that contains controlled anomalies.
Outcome: The proposed corpus contains controlled anomalies in speech and facial video recordings of subjects.

EmoProgress: Cumulated Emotion Progression Analysis in Dreams and Customer Service Dialogues (2024.lrec-main)

Copied to clipboard

Challenge: Emotion analysis often involves categorization of isolated textual units, but these are parts of longer discourses, like dialogues or stories.
Approach: They propose a novel annotation setup for emotion categorization corpora that allows to annotate the emotion up to the annotated sentence.
Outcome: The proposed annotation setup allows to answer the question which emotion is presumably experienced at a specific moment in time.

Challenge: Emotion is a critical characteristic to distinguish people from machines.
Approach: They propose a dataset with emotions labeling on all utterances in each dialogue . they use Friends TV scripts and Facebook messenger dialogues to collect the data .
Outcome: The proposed dataset is the first with emotions labeling on all utterances in each dialogue based on their textual content.
ESCP: Enhancing Emotion Recognition in Conversation with Speech and Contextual Prefixes (2024.lrec-main)

Challenge: Emotion Recognition in Conversation (ERC) aims to analyze the speaker’s emotional state in a conversation.
Approach: They propose to combine a directed acyclic graph and contextual prefixes to model historical utterances in a conversation and incorporate a contextual prefixed containing sentiment and semantics of historical .
Outcome: The proposed model achieves state-of-the-art (SOTA) performance on several public benchmarks.
Akan Cinematic Emotions (ACE): A Multimodal Multi-party Dataset for Emotion Recognition in Movie Dialogues (2025.findings-acl)

Challenge: Akan Cinematic Emotions (AkaCE) is the first multimodal emotion dialogue dataset for an African language . it contains 385 emotion-labeled dialogues and 6162 utterances across audio, visual, and textual modalities, along with word-level prosodic prominence annotations.
Approach: They propose to use AkaCE to analyze African cinematic emotions using word-level prosodic prominence annotations.
Outcome: The Akan Cinematic Emotions (AkaCE) dataset addresses the significant lack of resources for low-resource languages in emotion recognition research.

An Emotional Mess! Deciding on a Framework for Building a Dutch Emotion-Annotated Corpus (2020.lrec-1)

Copied to clipboard

Challenge: Existing frameworks for emotion recognition are limited and do not allow for categorical versus dimensional oppositions.
Approach: They propose to use the emotions joy, love, anger, sadness and fear as well as dimensional models to annotate texts from different domains and topics.
Outcome: The proposed frameworks are well-suited to annotate texts from different domains and topics, but the connotation of the labels strongly depends on the origin of the texts.
EMO-RL: Emotion-Rule-Based Reinforcement Learning Enhanced Audio-Language Model for Generalized Speech Emotion Recognition (2025.findings-emnlp)

Copied to clipboard

Challenge: Recent advances in reinforcement learning (RL) have shown promise in improving LALMs’ reasoning abilities, but their performance in affective computing tasks remains suboptimal.
Approach: They propose a framework incorporating reinforcement learning with two key innovations: Emotion Similarity-Weighted Reward (ESWR) and Explicit Structured Reasoning (ESR).
Outcome: The proposed framework improves LALMs' reasoning abilities on MELD and IEMOCAP datasets and shows strong generalization.

Copied to clipboard

Challenge: Existing emotion-annotated task-oriented corpora are limited in size, label richness, and public availability, creating a bottleneck for downstream tasks.
Approach: They propose a large-scale manually emotion-annotated corpus of task-oriented dialogues based on a multi-domain task-orientated dataset.
Outcome: The proposed method is based on a task-oriented dialogue dataset with 11K dialogues and 83K emotion annotations of user utterances.
