Inverse relations

[albernar]

Hello,

I was wondering whether there is a particular reason for adding the inverse relations in the graph.

Thanks in advance for your answer!

Hello @albernar ! I'm not the authors but I can try to provide an answer.

The reason this is done, I believe, is for better learning and data augmentation. If you look at Table 7, you see that the model was able to help predict the query <Florence, vacationer, D.C. Henrie> by seeing the inverse relationship of <Florence, contain^-1, Italy>. Without the inverses, the model could not follow this path as the original query was probably <Italy, contain, Florance>. Thus, starting at Florence as the u node, the model would not have followed this path because it couldn't have.
