The Fact Extraction and VERification Over Unstructured and Structured information (FEVEROUS) Shared Task

no code implementations EMNLP (FEVER) 2021 Rami Aly, Zhijiang Guo, Michael Sejr Schlichtkrull, James Thorne, Andreas Vlachos, Christos Christodoulopoulos, Oana Cocarascu, Arpit Mittal

The Fact Extraction and VERification Over Unstructured and Structured information (FEVEROUS) shared task, asks participating systems to determine whether human-authored claims are Supported or Refuted based on evidence retrieved from Wikipedia (or NotEnoughInfo if the claim cannot be verified).

PubHealthTab: A Public Health Table-based Dataset for Evidence-based Fact Checking

1 code implementation Findings (NAACL) 2022 Mubashara Akhtar, Oana Cocarascu, Elena Simperl

Inspired by human fact checkers, who use different types of evidence (e. g. tables, images, audio) in addition to text, several datasets with tabular evidence data have been released in recent years.

ChartCheck: Explainable Fact-Checking over Real-World Chart Images

1 code implementation13 Nov 2023 Mubashara Akhtar, Nikesh Subedi, Vivek Gupta, Sahar Tahmasebi, Oana Cocarascu, Elena Simperl

Whilst fact verification has attracted substantial interest in the natural language processing community, verifying misinforming statements against data visualizations such as charts has so far been overlooked.

Bias Mitigation Methods for Binary Classification Decision-Making Systems: Survey and Recommendations

no code implementations31 May 2023 Madeleine Waller, Odinaldo Rodrigues, Oana Cocarascu

Bias mitigation methods for binary classification decision-making systems have been widely researched due to the ever-growing importance of designing fair machine learning processes that are impartial and do not discriminate against individuals or groups based on protected personal characteristics.

An Explanatory Query-Based Framework for Exploring Academic Expertise

no code implementations28 May 2021 Oana Cocarascu, Andrew McLean, Paul French, Francesca Toni

The success of research institutions heavily relies upon identifying the right researchers "for the job": researchers may need to identify appropriate collaborators, often from across disciplines; students may need to identify suitable supervisors for projects of their interest; administrators may need to match funding opportunities with relevant researchers, and so on.

Automatic Product Ontology Extraction from Textual Reviews

no code implementations23 May 2021 Joel Oksanen, Oana Cocarascu, Francesca Toni

Ontologies have proven beneficial in different settings that make use of textual reviews.

A Dataset Independent Set of Baselines for Relation Prediction in Argument Mining

no code implementations14 Feb 2020 Oana Cocarascu, Elena Cabrio, Serena Villata, Francesca Toni

Argument Mining is the research area which aims at extracting argument components and predicting argumentative relations (i. e., support and attack) from text.

Combining Deep Learning and Argumentative Reasoning for the Analysis of Social Media Textual Content Using Small Data Sets

no code implementations CL 2018 Oana Cocarascu, Francesca Toni

In this article, we focus on analyzing whether news headlines support tweets and whether reviews are deceptive by analyzing the interaction or the influence that these texts have on the others, thus exploiting contextual information.

Identifying attack and support argumentative relations using deep learning

no code implementations EMNLP 2017 Oana Cocarascu, Francesca Toni

We propose a deep learning architecture to capture argumentative relations of attack and support from one piece of text to another, of the kind that naturally occur in a debate.
