Creating a comparison from papers in the ORKG

This tutorial shows you how you can create an ORKG Comparison from papers that have already been added to the ORKG beforehand. To accomplish this, you have two options:

Option 1 - Using the Contribution Editor

  • Step 1: Sign in

  • Step 2: Click on Add new and then Comparison

Repeat this step until all relevant contributions are added to your comparison.

If you additionally want to add a paper to the comparison that is not yet in the ORKG, you can follow the rest of this tutorial.

  • Step 6: Once you have added at least 2 contributions, click on View comparison. Now you can see a preview of the comparison that you can tweak to your liking. Please also see here, for information on how to organize the comparison.

  • Step 7: If you are satisfied with the comparison, you either publish your comparison. You can also save it as draft and come back to work on it later. You can find details on how to do that here.

Option 2: Using the Contribution Selection

This option is very useful if you are browsing content in the ORKG and want to create a comparison from interesting contributions you came across.

If you are viewing a paper, you always have the option to add all contributions of that paper to a comparison by selecting the check-box labelled Add to comparison.

This opens a red pop-up on the bottom right of your browser window. It shows you all contributions that you have currently selected. If you want to add more, you can do so by continue browsing ORKG papers. Don’t worry, the contributions you have already selected, will stay selected. You can also remove selected contributions by clicking on the x.

If you are happy with your selection, click on Start comparison.

Now you are ready to move on to the next step and tweak your comparison to your liking by clicking here.
