Constituency parsing aims to extract a constituency-based parse tree from a sentence that represents its syntactic structure according to a phrase structure grammar.
Although UD covers 130 languages, OntoNotes (NER, CON, SRL) covers only English, Chinese and Arabic. So NER/CON/SRL of languages other than the 3 are considered as Zero-Shot and their accuracies can be very low.
