Data extraction in evidence synthesis is labour-intensive, costly, and prone to errors. The use of large language models (LLMs) presents a promising approach for AI-assisted data extraction, potentially enhancing both efficiency and accuracy.
In this session, part of the Artificial Intelligence (AI) methods in evidence synthesis series, the presenter gave an overview of the current research landscape concerning data extraction using LLMs. The presenter also showed findings from a study within reviews (SWAR) that validated the workflow of employing an LLM for semi-automating data extraction within systematic reviews. Additionally, the webinar addressed current methodological challenges in evaluating LLMs for data extraction tasks.
This session was aimed at anyone conducting evidence synthesis. It was delivered in March 2025 and below you will find the videos from the webinar, together with the accompanying slides to download [PDF].
