ConvAbuse: Data, Analysis, and Benchmarks for Nuanced Detection in Conversational AI

no code implementations EMNLP 2021 Amanda Cercas Curry, Gavin Abercrombie, Verena Rieser

We find that the distribution of abuse is vastly different compared to other commonly used datasets, with more sexually tinted aggression towards the virtual persona of these systems.

Guiding the Release of Safer E2E Conversational AI through Value Sensitive Design

no code implementations SIGDIAL (ACL) 2022 A. Stevie Bergman, Gavin Abercrombie, Shannon Spruit, Dirk Hovy, Emily Dinan, Y-Lan Boureau, Verena Rieser

Over the last several years, end-to-end neural conversational agents have vastly improved their ability to carry unrestricted, open-domain conversations with humans.

NLP for Counterspeech against Hate: A Survey and How-To Guide

no code implementations29 Mar 2024 Helena Bonaldi, Yi-Ling Chung, Gavin Abercrombie, Marco Guerini

In recent years, counterspeech has emerged as one of the most promising strategies to fight online hate.

Subjective $\textit{Isms}$? On the Danger of Conflating Hate and Offence in Abusive Language Detection

no code implementations4 Mar 2024 Amanda Cercas Curry, Gavin Abercrombie, Zeerak Talat

Natural language processing research has begun to embrace the notion of annotator subjectivity, motivated by variations in labelling.

Abusive Language Hate Speech Detection +2

Understanding Counterspeech for Online Harm Mitigation

no code implementations1 Jul 2023 Yi-Ling Chung, Gavin Abercrombie, Florence Enock, Jonathan Bright, Verena Rieser

Counterspeech offers direct rebuttals to hateful speech by challenging perpetrators of hate and showing support to targets of abuse.

Mirages: On Anthropomorphism in Dialogue Systems

no code implementations16 May 2023 Gavin Abercrombie, Amanda Cercas Curry, Tanvi Dinkar, Verena Rieser, Zeerak Talat

In this paper, we discuss the linguistic factors that contribute to the anthropomorphism of dialogue systems and the harms that can arise, including reinforcing gender stereotypes and notions of acceptable language.

On the Origins of Bias in NLP through the Lens of the Jim Code

no code implementations16 May 2023 Fatma Elsafoury, Gavin Abercrombie

In this paper, we trace the biases in current natural language processing (NLP) models back to their origins in racism, sexism, and homophobia over the last 500 years.

iLab at SemEval-2023 Task 11 Le-Wi-Di: Modelling Disagreement or Modelling Perspectives?

no code implementations10 May 2023 Nikolas Vitsakis, Amit Parekh, Tanvi Dinkar, Gavin Abercrombie, Ioannis Konstas, Verena Rieser

There are two competing approaches for modelling annotator disagreement: distributional soft-labelling approaches (which aim to capture the level of disagreement) or modelling perspectives of individual annotators or groups thereof.

SemEval-2023 Task 11: Learning With Disagreements (LeWiDi)

no code implementations28 Apr 2023 Elisa Leonardelli, Alexandra Uma, Gavin Abercrombie, Dina Almanea, Valerio Basile, Tommaso Fornaciari, Barbara Plank, Verena Rieser, Massimo Poesio

We report on the second LeWiDi shared task, which differs from the first edition in three crucial respects: (i) it focuses entirely on NLP, instead of both NLP and computer vision tasks in its first edition; (ii) it focuses on subjective tasks, instead of covering different types of disagreements-as training with aggregated labels for subjective NLP tasks is a particularly obvious misrepresentation of the data; and (iii) for the evaluation, we concentrate on soft approaches to evaluation.

Consistency is Key: Disentangling Label Variation in Natural Language Processing with Intra-Annotator Agreement

no code implementations25 Jan 2023 Gavin Abercrombie, Verena Rieser, Dirk Hovy

We commonly use agreement measures to assess the utility of judgements made by human annotators in Natural Language Processing (NLP) tasks.

Risk-graded Safety for Handling Medical Queries in Conversational AI

1 code implementation2 Oct 2022 Gavin Abercrombie, Verena Rieser

While individual crowdworkers may be unreliable at grading the seriousness of the prompts, their aggregated labels tend to agree with professional opinion to a greater extent on identifying the medical queries and recognising the risk types posed by the responses.

ConvAbuse: Data, Analysis, and Benchmarks for Nuanced Abuse Detection in Conversational AI

1 code implementation20 Sep 2021 Amanda Cercas Curry, Gavin Abercrombie, Verena Rieser

We find that the distribution of abuse is vastly different compared to other commonly used datasets, with more sexually tinted aggression towards the virtual persona of these systems.

Anticipating Safety Issues in E2E Conversational AI: Framework and Tooling

no code implementations7 Jul 2021 Emily Dinan, Gavin Abercrombie, A. Stevie Bergman, Shannon Spruit, Dirk Hovy, Y-Lan Boureau, Verena Rieser

Over the last several years, end-to-end neural conversational agents have vastly improved in their ability to carry a chit-chat conversation with humans.

ParlVote: A Corpus for Sentiment Analysis of Political Debates

no code implementations LREC 2020 Gavin Abercrombie, Riza Batista-Navarro

These include a linear classifier as well as a neural network trained using a transformer word embedding model (BERT), and fine-tuned on the parliamentary speeches.

Sentiment Analysis

Policy Preference Detection in Parliamentary Debate Motions

no code implementations CONLL 2019 Gavin Abercrombie, Federico Nanni, Riza Batista-Navarro, Simone Paolo Ponzetto

Debate motions (proposals) tabled in the UK Parliament contain information about the stated policy preferences of the Members of Parliament who propose them, and are key to the analysis of all subsequent speeches given in response to them.

General Classification

Semantic Change in the Language of UK Parliamentary Debates

no code implementations WS 2019 Gavin Abercrombie, Riza Batista-Navarro

We investigate changes in the meanings of words used in the UK Parliament across two different epochs.

Sentiment and position-taking analysis of parliamentary debates: A systematic literature review

no code implementations9 Jul 2019 Gavin Abercrombie, Riza Batista-Navarro

In this article we present the results of a systematic literature review of 61 studies, all of which address the automatic analysis of the sentiment and opinions expressed and positions taken by speakers in parliamentary (and other legislative) debates.

Position

Identifying Opinion-Topics and Polarity of Parliamentary Debate Motions

no code implementations WS 2018 Gavin Abercrombie, Riza Theresa Batista-Navarro

Analysis of the topics mentioned and opinions expressed in parliamentary debate motions{--}or proposals{--}is difficult for human readers, but necessary for understanding and automatic processing of the content of the subsequent speeches.

A Rule-based Shallow-transfer Machine Translation System for Scots and English

no code implementations LREC 2016 Gavin Abercrombie

By concentrating on translation for assimilation (gist comprehension) from Scots to English, it is proposed that the development of dictionaries designed to be used with in the Apertium platform will be sufficient to produce translations that improve non-Scots speakers understanding of the language.
