How to add a custom attribute to entities in the knowledge base?

[amirj]

Is it possible to add a custom attribute when adding a new entity to the knowledge base? e.g. a boolean field that could be accessed via entity linker.

Hi!

I'm afraid that's currently not provided in the built-in implementation, which is tailored towards memory/disk efficiency as knowledge bases tend to grow quite large. I think you have two options to work around this:

• Implement a custom KnowledgeBase by extending the provided one.
• Store the additional information in a separate data structure / database that you query independently of the NEL/KB functionality
