How to use sarscov2web

The sarscov2web functionality pipeline begins at the homepage where a list of 22 annotation/entity types is provided.(Right click on the image below and select "view image" for a larger view) Responsive image By clicking on any of the annotation-types the user is led to a list of type-names ordered by the number of times the term has been mentioned in the whole sarscov2web corpus. For example, if you choose to select the annotation type "Diseases" as can be seen from image 1 above, you will be led to a page with a list of diseases related to COVID ordered by the number of times the term has been mentioned in whole sarscov2web corpora.In simple words, the term with most mentions will appear first as can be seen in the image below where the term "Communicable Diseases" ranks first.

It is important to emphasis at this point that the number of mentions(count column) is not equal to the number of articles that have mentioned the term. For example, the total count for the term "Communicable Diseases" is 565,596(see image below). On the other hand, the number of articles that have mentioned the term "Communicable Diseases" at least once total to 53,883. So don't worry. Nothing is broken.

Finally, the sarscov2web pipeline ends with the articles themselves. By clicking on the term, the user is led to a page that lists references to all articles that have mentioned the selected term atleast once. The total number of articles is different from the total number of times the term has been mentioned in the whole corpora.

Here is another example to underline this point. The term "Asthma" has been mentioned 39,161 times( see image above) in the whole body of literature contained in the sarscov2web database but has actually been mentioned by 4,897 articles.(see image below) Responsive image
