Joint Modelling of Emotion and Abusive Language Detection (2020.acl-main)
Copied to clipboard
| Challenge: | Existing methods for abuse detection focus on linguistic properties of comments and online communities of users, disregarding the emotional state of the users and how this might affect their language. |
| Approach: | They propose to combine emotion and abusive language detection to create a multi-task learning framework that allows one task to inform the other. |
| Outcome: | The proposed model improves on the previous models, incorporating affective features into the learning framework. |
Scientific and Creative Analogies in Pretrained Language Models (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing analogy datasets focus on a limited set of analogical relations with a high similarity of the two domains between which the analogy holds. |
| Approach: | They propose a dataset that encodes analogy in pretrained language models . they use a system that maps attributes and relational structures across dissimilar domains . |
| Outcome: | The proposed dataset shows that state-of-the-art models achieve low performance on analogy tasks . |
Ruddit: Norms of Offensiveness for English Reddit Comments (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods to detect offensive language have been limited by categorical labels . however, there are several challenges in the detection of such content . |
| Approach: | They analyze Reddit comments with fine-grained, real-valued offensiveness scores . they evaluate the ability of widely-used neural models to predict offensiveness . |
| Outcome: | The proposed method produces highly reliable offensiveness scores and can predict scores on reddit comments. |

| Challenge: | Using value profiles and a steerable decoder model to estimate ratings is crucial for personalization, pluralistic model alignment, and computational social science. |
| Approach: | They propose to represent individuals using value profiles and a steerable decoder model to estimate ratings conditioned on a value profile or other rater information. |
| Outcome: | The proposed model interpretably changes ratings according to semantic profile differences and is well-calibrated. |
Author Profiling for Abuse Detection (C18-1)
Copied to clipboard
| Challenge: | Existing methods for detecting abusive content rely on textual cues and lexical cue information. |
| Approach: | They propose a method that incorporates community-based profiling features of Twitter users to detect abusive content by using a dataset of 16k tweets. |
| Outcome: | The proposed approach outperforms the current state-of-the-art in abuse detection on a dataset of 16k tweets. |
A (More) Realistic Evaluation Setup for Generalisation of Community Models on Malicious Content Detection (2024.findings-naacl)
Copied to clipboard
| Challenge: | despite the performance of community models for malicious content detection, misinformation and hate speech continue to propagate on social media networks. |
| Approach: | They propose a new evaluation setup for community models for malicious content detection based on a few-shot subgraph sampling approach to test generalisation of models using local explorations of a larger graph. |
| Outcome: | The proposed evaluation setup outperforms existing models on real-world graphs on a training graph. |
Abusive Language Detection with Graph Convolutional Networks (N19-1)
Copied to clipboard
| Challenge: | Existing approaches to abusive language detection only capture shallow properties of online communities . a new approach captures both the structure of online community and linguistic behavior of users . |
| Approach: | They propose a graph convolutional network approach that captures the linguistic behavior of users . they propose to model homophily by embeddings for authors that encode the structure of their communities . |
| Outcome: | The proposed approach captures both the structure and linguistic behavior of users in online communities . authors show that the proposed approach significantly advances the current state of the art . |
Modeling Users and Online Communities for Abuse Detection: A Position on Ethics and Explainability (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Abuse on the Internet is an important societal problem of our time. |
| Approach: | They propose to use user and community information to enhance detection of abusive language . they propose to propose properties that an explainable method should aim to exhibit . |
| Outcome: | The proposed methods leverage user and community information to enhance detection of abusive language. |
Learning to Learn to Disambiguate: Meta-Learning for Few-Shot Word Sense Disambiguation (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for word sense disambiguation (WSD) are limited and require large datasets annotated with word senses. |
| Approach: | They propose a meta-learning framework for few-shot word sense disambiguation where the goal is to learn to disambiguate unseen words from only a few labeled instances. |
| Outcome: | The proposed framework is based on a large training dataset and a small number of examples. |
Multilingual and cross-lingual document classification: A meta-learning approach (2021.eacl-main)
Copied to clipboard
| Challenge: | Existing methods to document classification in low-resource languages are under-resourced . 6% of the world's languages are spoken, and many have inadequate resources . |
| Approach: | They propose a meta-learning approach to document classification in low-resource languages . they propose 'nuclear-shot' cross-lingual adaptation to previously unseen languages based on limited data . |
| Outcome: | The proposed method performs on-par on some languages while under-resourced in others. |
