Factual Consistency Evaluation of Summarisation in the Era of Large Language Models

no code implementations21 Feb 2024 Zheheng Luo, Qianqian Xie, Sophia Ananiadou

Experiments on TreatFact suggest that both previous methods and LLM-based evaluators are unable to capture factual inconsistencies in clinical summaries, posing a new challenge for FC evaluation.

Graph Contrastive Topic Model

1 code implementation5 Jul 2023 Zheheng Luo, Lei Liu, Qianqian Xie, Sophia Ananiadou

Based on it, we propose the graph contrastive topic model (GCTM), which conducts graph contrastive learning (GCL) using informative positive and negative samples that are generated by the graph-based sampling strategy leveraging in-depth correlation and irrelevance among documents and words.

ChatGPT as a Factual Inconsistency Evaluator for Text Summarization

no code implementations27 Mar 2023 Zheheng Luo, Qianqian Xie, Sophia Ananiadou

In this paper, we particularly explore ChatGPT's ability to evaluate factual inconsistency under a zero-shot setting by examining it on both coarse-grained and fine-grained evaluation tasks including binary entailment inference, summary ranking, and consistency rating.

CitationSum: Citation-aware Graph Contrastive Learning for Scientific Paper Summarization

no code implementations26 Jan 2023 Zheheng Luo, Qianqian Xie, Sophia Ananiadou

To fill that gap, we propose a novel citation-aware scientific paper summarization framework based on citation graphs, able to accurately locate and incorporate the salient contents from references, as well as capture varying relevance between source papers and their references.

Readability Controllable Biomedical Document Summarization

no code implementations10 Oct 2022 Zheheng Luo, Qianqian Xie, Sophia Ananiadou

Different from general documents, it is recognised that the ease with which people can understand a biomedical text is eminently varied, owing to the highly technical nature of biomedical documents and the variance of readers' domain knowledge.
