Natural language understanding is a technology that allows you to find certain objects in arbitrary text and mark them.

>>> from yandex_speech import NLU
>>> nlu = NLU("60589d42-0e42-b742-8942-thekeyisalie")
>>> nlu.parse("31 апреля родился Хлусов Геннадий Викторович", ("Date", "Fio"))
{'Date': [{'Tokens': {'Begin': 0, 'End': 2}, 'Month': 4, 'Day': 31}], 'Fio': [{'Patronymic': 'викторович', 'Type': 'fioname', 'Tokens': {'Begin': 3, 'End': 6}, 'FirstName': 'генадий', 'LastName': 'хлусов'}]}
