Patent number: 11724403Abstract: A system, method and computer-readable storage devices are for processing natural language commands, such as commands to a robotic arm, using a Tag & Parse approach to semantic parsing. The system first assigns semantic tags to each word in a sentence and then parses the tag sequence into a semantic tree. The system can use statistical approach for tagging, parsing, and reference resolution. Each stage can produce multiple hypotheses, which are re-ranked using spatial validation. Then the system selects a most likely hypothesis after spatial validation, and generates or outputs a command. In the case of a robotic arm, the command is output in Robot Control Language (RCL).Type: GrantFiled: February 6, 2020Date of Patent: August 15, 2023Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Svetlana Stoyanchev, Srinivas Bangalore, John Chen, Hyuckchul Jung

Publication number: 20220147719Abstract: A dialogue system comprising: a user input a processor; and a memory wherein the processor is adapted to update a dialogue state in response to a natural language input from a user, the dialogue state being stored in the memory, the dialogue state comprising data structure that the stores the information exchanged between the user and the dialogue system, the processor being configured to update said dialogue state by comparing said natural language input from the user with a plurality of possible actions, said actions indicating possible requests of the user, and update the state using information from an action that matches with the natural language input, the processor being configured to generate a response to the natural language input using the updated state.Type: ApplicationFiled: February 26, 2021Publication date: May 12, 2022Applicant: Kabushiki Kaisha ToshibaInventors: Svetlana STOYANCHEV, Simon KEIZER, Rama Sanand DODDIPATLA

Patent number: 11288457Abstract: Systems and methods are disclosed for determining a move driven by an interaction. In some embodiments, a processor determines an operational state of an interaction with a user based on parameter values of a data structure. The processor identifies a plurality of candidate moves for changing the operational state by determining a domain in which the interaction is occurring, retrieving a set of candidate moves that correspond to the domain from a knowledge graph, and adding the set to the plurality of candidate moves. The processor encodes input of the user received during the interaction into encoded terms, and determines a move for changing the operational state based on a match of the encoded terms to the set of candidate moves. The processor updates the parameter values of the data structure based on the move to reflect a current operational state led to by the move.Type: GrantFiled: February 1, 2019Date of Patent: March 29, 2022Assignee: Interactions LLCInventors: Svetlana Stoyanchev, Michael Johnston

Patent number: 10665226Abstract: Systems, methods, and computer-readable storage devices for generating speech using a presentation style specific to a user, and in particular the user's social group. Systems configured according to this disclosure can then use the resulting, personalized, text and/or speech in a spoken dialogue or presentation system to communicate with the user. For example, a system practicing the disclosed method can receive speech from a user, identify the user, and respond to the received speech by applying a personalized natural language generation model. The personalized natural language generation model provides communications which can be specific to the identified user.Type: GrantFiled: June 4, 2019Date of Patent: May 26, 2020Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Taniya Mishra, Alistair D.

Patent number: 9953644Abstract: A system, method and computer-readable storage devices are disclosed for using targeted clarification (TC) questions in dialog systems in a multimodal virtual agent system (MVA) providing access to information about movies, restaurants, and musical events. In contrast with open-domain spoken systems, the MVA application covers a domain with a fixed set of concepts and uses a natural language understanding (NLU) component to mark concepts in automatically recognized speech. Instead of identifying an error segment, localized error detection (LED) identifies which of the concepts are likely to be present and correct using domain knowledge, automatic speech recognition (ASR), and NLU tags and scores. If at least concept is identified to be present but not correct, the TC component uses this information to generate a targeted clarification question.Type: GrantFiled: December 1, 2014Date of Patent: April 24, 2018Assignee: AT&T Intellectual Property I, L.P.Inventors: Ethan Selfridge, Michael J.
