Creating a comparison from papers not yet in the ORKG

Step 1: Sign in

Step 2: Click on Add new and then Comparison

Step 3: This leads you to an overview page for adding comparisons. Choose option 2 "Contribution editor"

Step 4: Now the contribution editor has opened. To add your first contribution click on Add contribution on the top right.

Step 5: A pop-up window will appear. If you are not sure whether your paper might not already exist in the ORKG, you can enter the paper title or DOI. For adding papers that are already added to the ORKG check out this tutorial instead. For this tutorial, we assume you want to add your papers from scratch. So now, click on Add new paper on the bottom left of this pop-up window.

Step 6: A new pop-up window will appear, which will ask you to create a new paper in the ORKG. If you need help with adding papers, this course might be interesting for you.

Step 7: You can now see that the paper has been added to the contribution editor and you can start to model your data. You can add new properties by clicking on Add property or use a template by clicking on Templates. If you need help with semantic modelling, check out our article on that topic here. If some of the papers you want to compare are already present in the ORKG, you can also add those additionally to the newly added ones. For how to do this, please click here.

Step 8: 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 9: 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. For details on how to do that, please take a look here.
