COVID-19 trial graph: a linked graph for COVID-19 clinical trials.

ABSTRACT:

Objective

Clinical trials are an essential part of the effort to find safe and effective prevention and treatment for COVID-19. Given the rapid growth of COVID-19 clinical trials, there is an urgent need for a better clinical trial information retrieval tool that supports searching by specifying criteria, including both eligibility criteria and structured trial information.

We linked the extracted data using the COVID-1
