Improved Topic Representations of Medical Documents to Assist COVID-19 Literature Exploration

no code implementations EMNLP (NLP-COVID19) 2020 Yulia Otmakhova, Karin Verspoor, Timothy Baldwin, Simon Šuster

Efficient discovery and exploration of biomedical literature has grown in importance in the context of the COVID-19 pandemic, and topic-based methods such as latent Dirichlet allocation (LDA) are a useful tool for this purpose.

Cross-linguistic Comparison of Linguistic Feature Encoding in BERT Models for Typologically Different Languages

no code implementations NAACL (SIGTYP) 2022 Yulia Otmakhova, Karin Verspoor, Jey Han Lau

Though recently there have been an increased interest in how pre-trained language models encode different linguistic features, there is still a lack of systematic comparison between languages with different morphology and syntax.

The patient is more dead than alive: exploring the current state of the multi-document summarisation of the biomedical literature

no code implementations ACL 2022 Yulia Otmakhova, Karin Verspoor, Timothy Baldwin, Jey Han Lau

Although multi-document summarisation (MDS) of the biomedical literature is a highly valuable task that has recently attracted substantial interest, evaluation of the quality of biomedical summaries lacks consistency and transparency.

Generative Debunking of Climate Misinformation

no code implementations8 Jul 2024 Francisco Zanartu, Yulia Otmakhova, John Cook, Lea Frermann

Misinformation about climate change causes numerous negative impacts, necessitating corrective responses.

Automated Metrics for Medical Multi-Document Summarization Disagree with Human Evaluations

1 code implementation23 May 2023 Lucy Lu Wang, Yulia Otmakhova, Jay DeYoung, Thinh Hung Truong, Bailey E. Kuehl, Erin Bransom, Byron C. Wallace

We analyze how automated summarization evaluation metrics correlate with lexical features of generated summaries, to other automated metrics including several we propose in this work, and to aspects of human-assessed summary quality.

COVID-SEE: Scientific Evidence Explorer for COVID-19 Related Research

no code implementations18 Aug 2020 Karin Verspoor, Simon Šuster, Yulia Otmakhova, Shevon Mendis, Zenan Zhai, Biaoyan Fang, Jey Han Lau, Timothy Baldwin, Antonio Jimeno Yepes, David Martinez

We present COVID-SEE, a system for medical literature discovery based on the concept of information exploration, which builds on several distinct text analysis and natural language processing methods to structure and organise information in publications, and augments search by providing a visual overview supporting exploration of a collection to identify key articles of interest.
