A web-based knowledge hub for exploration of multiple research article collections

Medical decision-making is guided by the results of rich medical research and clinical trials. Doctors, practitioners and researchers urgently need to get updated by the most recent research and clinical outputs to make correct decisions, especially when a new virus such as Covid-19 is causing a global epidemic. However, medical literature for a certain topic could be from different aspects thus archived in different literature databases, resulting in the searching for all related articles become a laborious and time-consuming task. It becomes worse when there is a rapid growth of the number of published literature for the given topic. In this work, we build an online knowledge hub (http://covid19knowledgehub.herokuapp.com/) particularly for Covid-19 related research articles per the requirement from researchers in a hospital. The system is built on top of nine medical research article databases, which covers a wide range of medical aspects. It allows users to easily retrieve and explore the articles from multiple literature databases at one-stop. The system also provides the statistics of article distributions to offer an overview of the status of research under this topic. This real-demand driven system is deployed in a research team of Renmin Hospital, Wuhan University, and largely reduces their time for searching the latest articles. Although this project focuses on Covid-19 related research articles, the approach at the back could be applied to any topic in any domain.
