Frequently Asked Questions

Q: What is the purpose of this resource?

A: To provide a portal to the entire biomedical literature focussed on SARS-CoV-2, MERS-CoV and SARS-CoV. It categorises papers into a set of topics to make it easier to find relevant research and indexes by important concepts (e.g. drugs, proteins, locations, etc).


Q: How do I find papers that mention a specific therapeutic?

A: We find drug names extracted from Wikidata in papers and use a set of synonyms to extract them.


Q: What machine learning methods are used in this resource?

A: We use supervised machine learning to identify the topics of the papers. A set of papers has been annotated with relevant topics and used as training data for a system that uses the text of the title and abstract to make predictions. This is complemented with heuristics to identify specific topics, e.g. clinical trial registration numbers.


Q: Are all the papers manually curated?

A: No. A small number have been manually curated and machine learning has been used to predict the topics for all other papers


Q: Is this up-to-date?

A: Yes. The latest version of PubMed and the CORD-19 dataset are downloaded and processed every day.


Q: I've found a mistake with a paper. What should I do?

A: Please flag the paper using the Flag Mistake button on the paper or use the Feedback page.


Q: Who created this resource?

A: This was created by Jake Lever, a postdoctoral researcher, supervised by Russ Altman in the Helix Group at Stanford University.


Q: How do I cite this research?

A: There is currently a paper in preparation. Please cite that when it becomes available.


Q: Who should I contact to ask a question?

A: Please contact Jake Lever at jlever@stanford.edu
