Abstract: Techniques to be used in natural language understanding (NLU) are described. For example, a NLU service to receive a request to analyze a written or spoken utterance; tokenize the received utterance; generate one or more labels corresponding to a substring of the tokenized received utterance, each of the labels including one or more slot types, by: for each path of a grammar-based finite state transducer (FST) data structure that includes instructions, traversing the path as far as possible for matches from a previous breakpoint, while maintaining i) locations of branching points and snapshots at those branching points and ii) an indication of which paths have been traversed, and recording a result of each path traversal as a generated label; resolve the one or more generated labels into machine-readable values; and output a result is described.

Abstract: A data-collecting device acquires data associated with a real-time data stream and transmits the data to a data-consuming service hosted on a server computer system in the form of a multipart response. The multipart response includes one or more data content parts and at least one authentication content part. Each of the one or more data content parts contains data representing part of the real-time data stream. Each authentication content part includes authentication information usable to verify the integrity of the data transmitted in the data content parts transmitted prior to the authentication content part.
