How to get the ontology.json for MultiWOZ 2.2?

[Young973]

Hi, may I ask how to get the "ontology.json" for MultiWOZ 2.2 like 2.0 and 2.1? Since the slots are not exactly same as those in 2.0 and 2.1, I think the ontology.json should be different.

Hi, schema.json file serves as the ontology for MultiWOZ 2.2. Please note that one point that MultiWOZ 2.2 tries to make is that it's hard for the dialogue system to have a ontology that enumerates all the possible values of all the slots. Thus, MultiWOZ 2.2 contributes a schema file following the format in the Schema-Guided Dialogue dataset.
