MAPLE: Micro Analysis of Pairwise Language Evolution for Few-Shot Claim Verification

Published in EACL Findings 2024, 2024

We propose MAPLE (Micro Analysis of Pairwise Language Evolution), a pioneering approach that explores the alignment between a claim and its evidence with a small seq2seq model and a novel semantic measure.

Active PETs: Active Data Annotation Prioritisation for Few-Shot Claim Verification with Pattern Exploiting Training

Published in EACL Findings 2023, 2023

We propose Active PETs, a novel weighted approach that utilises an ensemble of Pattern Exploiting Training (PET) models based on various language models, to actively select unlabelled data as candidates for annotation.

Aggregating pairwise semantic differences for few-shot claim verification

Published in PeerJ Computer Science, 2022

This article introduces Semantic Embedding Element-wise Difference (SEED), a novel vector-based method to few-shot claim verification that aggregates pairwise semantic differences for claim-evidence pairs.

QMUL-SDS at SCIVER: Step-by-Step Binary Classification for Scientific Claim Verification

Published in Proceedings of the Second Workshop on Scholarly Document Processing, 2021

In this paper, we propose an approach that performs scientific claim verification by doing binary classifications step-by-step.
