Patent number: 11741309Abstract: An agent automation system includes a memory configured to store a natural language understanding (NLU) framework and a model, wherein the model includes at least one original meaning representation. The system includes a processor configured to execute instructions of the NLU framework to cause the agent automation system to perform actions including: performing rule-based generalization of the model to generate at least one generalized meaning representation of the model from the at least one original meaning representation of the model; performing rule-based refinement of the model to prune or modify the at least one generalized meaning representation of the model, or the at least one original meaning representation of the model, or a combination thereof; and after performing the rule-based generalization and the rule-based refinement of the model, using the model to extract intents/entities from a received user utterance.Type: GrantFiled: March 24, 2021Date of Patent: August 29, 2023Assignee: ServiceNow, Inc.Inventors: Edwin Sapugay, Anil Kumar Madamala, Maxim Naboka, Srinivas SatyaSai Sunkara, Lewis Savio Landry Santos, Murali B.

Patent number: 11681877Abstract: An agent automation system implements a virtual agent that is capable of learning new words, or new meanings for known words, based on exchanges between the virtual agent and a user in order to customize the vocabulary of the virtual agent to the needs of the user or users. The agent automation framework has access to a corpus of previous exchanges between the virtual agent and the user, such as one or more chat logs. New words and/or new meanings for known words are identified within the corpus and new word vectors are generated for these new words and/or new meanings for known words and added to refine a word vector distribution model. The refined word vector distribution model is then utilized by the agent automation system to interact with the user.Type: GrantFiled: March 11, 2021Date of Patent: June 20, 2023Assignee: ServiceNow, Inc.Inventors: Edwin Sapugay, Anil Kumar Madamala, Maxim Naboka, Srinivas SatyaSai Sunkara, Lewis Savio Landry Santos, Murali B.

Publication number: 20220058343Abstract: Present embodiment include a prosody subsystem of a natural language understanding (NLU) framework that is designed to analyze collections of written messages for various prosodic cues to break down the collection into a suitable level of granularity (e.g., into episodes, sessions, segments, utterances, and/or intent segments) for consumption by other components of the NLU framework, enabling operation of the NLU framework. These prosodic cues may include, for example, source prosodic cues that are based on the author and the conversation channel associated with each message, temporal prosodic cues that are based on a respective time associated with each message, and/or written prosodic cues that are based on the content of each message. For example, to improve the domain specificity of the agent automation system, intent segments extracted by the prosody subsystem may be consumed by a training process for a ML-based structure subsystem of the NLU framework.Type: ApplicationFiled: November 3, 2021Publication date: February 24, 2022Inventors: Edwin Sapugay, Anil Kumar Madamala, Maxim Naboka, Srinivas SatyaSai Sunkara, Lewis Savio Landry Santos, Murali B.
