Why Should This Article Be Deleted? Transparent Stance Detection in Multilingual Wikipedia Editor Discussions

Published in EMNLP 2023, 2023

This paper tackles the transparency issue in online content moderation, using Wikipedia as a case study where moderation decisions are publicly discussed. The study introduces a multilingual dataset from Wikipedia editor discussions, demonstrating that combining editor stance and policy reasoning can be accurately predicted, contributing to increased transparency in content moderation.

Thorny Roses: Investigating the Dual Use Dilemma in Natural Language Processing

Published in EMNLP 2023 (Findings of the Association for Computational Linguistics), 2023

This paper explores the growing concern of dual use in Natural Language Processing (NLP) as technologies become more advanced and opaque. Surveying NLP researchers, it reveals widespread concerns about potential misuse with limited proactive measures. The paper proposes a tailored definition of dual use for NLP, discusses the current state of the issue, and suggests mitigation strategies, including a checklist for ethics frameworks like the ACL checklist.

Probing Pre-Trained Language Models for Cross-Cultural Differences in Values

Published in Wiki Workshop at the Web Conference, 2023

This paper delves into the exploration of social, cultural, and political values encoded in Pre-Trained Language Models (PTLMs) and investigates how these values vary across cultures. Introducing probes for systematic study, the research reveals that PTLMs capture cultural differences in values, although alignment with established cross-cultural value surveys is weak.

TempEL: Linking Dynamically Evolving and Newly Emerging Entities

Published in NeurIPS 2022, 2022

The paper presents TempEL, a new dataset for entity linking that captures the impact of evolving entities over time. Using time-stratified English Wikipedia snapshots from 2013 to 2022, TempEL reveals a decrease in entity linking accuracy for both continual entities (up to 3.1%) and newly emerging entities (up to 17.9%), highlighting the challenge of time-evolving entity disambiguation and suggesting new directions for research in this field.
