Towards Transforming Expert-based Content to Evidence-based Content

The goal of this paper is to find relevant citations for clinicians’ written content and make it more reliable by adding scientific articles as references and enabling the clinicians to easily update it using new information. The proposed approach uses information retrieval and ranking techniques to extract and rank relevant citations from MEDLINE for any given sentence. Additionally, this system extracts snippets of relevant content from ranked citations. We assessed our approach on 4,697 MEDLINE papers and their corresponding full-text on the subject of Heart Failure. We implemented multi-level and weight ranking algorithms to rank the citations. We demonstrate that using journal relevance and study design type improves results obtained from only using content similarity by approximately 40%. We also show that using full-text, rather than abstract text, leads to extracting higher quality snippets.
