Where can I find a labeled dataset of sentences classified by type (interrogative and declarative)? I'm particularly lookings for Russian sentences, but other open and labeled datasets of other languages will be helpful.
Basically, I need a dataset of sentences, which not consist only of question words, and sometimes don't have a question mark. It will be good, if dataset will have some declarative sentences with question mark (e.g. 'The bus has already left?')
