AI can help with the scale, efficiency, quality and understanding of some SLRs.
- Scale/volume of evidence: AI can enable literature reviews at scales not previously considered feasible. The larger the SLR, the greater the benefit.
- Efficiency: AI can learn from initial work, speeding up subsequent updates.
- Quality: with appropriate checks, AI has the potential to improve accuracy and reduce researcher bias.
- Understanding: AI can help to summarize, group and visualize data, revealing patterns and trends in the underlying information.
AI can help across the full workflow of SLR development, if used correctly and with people to check and adjust the output. In the article, we look at approaches by stage of SLR, from early scoping, through searching and screening, to extracting data, assessing the quality of the studies and, finally, synthesizing and visualizing the findings.
However, before using an AI tool or platform, it needs to be critically appraised to understand the potential advantages and risks. We note important ethical, practical, business and legal considerations when using AI relating to confidentiality of information and the quality of the output.
We believe that a fundamental principle for the use of AI in SLRs is that the authors are responsible for the quality and accuracy of their work, whether developed entirely by themselves or with assistance from AI – the use of AI does not alter the author’s ownership of quality. Humans providing expert knowledge and oversight are crucial. AI should be considered an augmentation, not a human replacement. A rigorous methodology with multiple layers of human validation should be developed and agreed by all authors involved in the SLR. We also note other requirements when using AI, including aligning with relevant institutional and corporate policies, and being transparent in reporting its use.
We think that it is up to all of us to keep engaging with AI, to be alert to new approaches and applications, and to evaluate, upskill and start to use these new and evolving tools.
