A survey on explainability in machine reading comprehension

M Thayaparan, M Valentino, A Freitas - arXiv preprint arXiv:2010.00389, 2020 - arxiv.org
This paper presents a systematic review of benchmarks and approaches for explainability in
Machine Reading Comprehension (MRC). We present how the representation and …

Hybrid autoregressive inference for scalable multi-hop explanation regeneration

M Valentino, M Thayaparan, D Ferreira… - Proceedings of the AAAI …, 2022 - ojs.aaai.org
Regenerating natural language explanations in the scientific domain has been proposed as
a benchmark to evaluate complex multi-hop and explainable inference. In this context, large …

A framework for evaluation of machine reading comprehension gold standards

V Schlegel, M Valentino, A Freitas, G Nenadic… - arXiv preprint arXiv …, 2020 - arxiv.org
Machine Reading Comprehension (MRC) is the task of answering a question over a paragraph

Does my representation capture X? Probe-ably

…, J Rozanova, M Thayaparan, M Valentino… - arXiv preprint arXiv …, 2021 - arxiv.org
Probing (or diagnostic classification) has become a popular strategy for investigating whether
a given set of intermediate features is present in the representations of neural models. …

SemEval-2024 task 2: Safe biomedical natural language inference for clinical trials

M Jullien, M Valentino, A Freitas - arXiv preprint arXiv:2404.04963, 2024 - arxiv.org
Large Language Models (LLMs) are at the forefront of NLP achievements but fall short in
dealing with shortcut learning, factual inconsistency, and vulnerability to adversarial inputs.…

On the nature of explanation: An epistemological-linguistic perspective for explanation-based natural language inference

M Valentino, A Freitas - Philosophy & Technology, 2024 - Springer
One of the fundamental research goals for explanation-based Natural Language Inference (NLI)
is to build models that can reason in complex domains through the generation of natural …

Multi-operational mathematical derivations in latent space

M Valentino, J Meadows, L Zhang, A Freitas - arXiv preprint arXiv …, 2023 - arxiv.org
