Multiple overlapping results from EntityRuler

[rubmz]

Feature description

When doing rule-based entity matching there's a need to score overlapping results and compare the best option based on various criteria. Problem is: EntityRuler overrides existing entities and won't give all the possible patterns that may match some span.
An even better option would be to supply a scoring function along with the patterns, taking the highest score as the winning match...

Guess this can be implemented as an external custom component or spaCy plugin.

After looking into the implementation details of EntityRuler, seems better just use a Matcher with callback. But this feature still is required IMHO.

Yes, the EntityRuler is basically just a wrapper around the Matcher and/the PhraseMatcher, so you can use those directly with your own filtering. There are so many different scoring options that I think it's going to be tricky to add a generic and useful scoring option to the EntityRuler (handling the serialization is the tricky part), but we can keep this in mind as a potential feature.
