So, er, how exactly would I prove it? Do you want me to share our code / db / etc we've worked on for past ~two years? :)
For one - how many wikidata classes exactly do you get from Wikineural? If I remember correctly, it can do four (person, location, organization, other). Our models do several thousands.
It'll likely annotate similar things in text since our model is also transformers-based (which is basically current state of art) - can't really do anything about that.
edit: phrasing.
