self-supervised entity linker

Thanks for making the code available online.
I want to insert a new knowledge graph like (ConceptNet) into KnowBert. To do that I need to train an entity linker for it. However, I don't have labelled data for the entity linker, and as I understood from the paper, it is possible to train the linker in a self-supervised way.
How to adapt the configuration files in order to do this task ?

Thanks in advance
