  • GENERATING LONG-TERM MEMORY FOR ORCHESTRATION AGENT SESSIONS
    Publication number: 20260017487
    Abstract: Long-term memory data objects may be generated for orchestrations agents. When a session completes or ends, a long-term memory data object may be generated according to a specified long-term memory type based on turn inputs during the session. When a new session is started, the long-term memory data object may be used as part of inputs to a generative machine learning model to perform or respond to turn inputs of the new session.

  • Dynamic entity catalog update for natural language processing
    Patent number: 12518095
    Abstract: A natural language processing system may implement dynamic entity catalog updates. An updated version of an entity catalog describing possible values for entities may be obtained. Respective natural language processing stage artifacts may be generated based on the updated version of the entity catalog for different processing stages of the natural language processing system. The natural language processing stage artifacts may be deployed to the different processing stages of the natural language processing system to replace a prior version of the entity catalog for processing subsequently received input text.

  • Composite slot type for natural language processing
    Patent number: 12406145
    Abstract: A natural language processing system may implement one or more composite slot types. The natural language processing system may receive a request to create a composite parameter type for causing performance by the natural language processing system of an intended action. The natural language processing system determines based on the request, a plurality of sub-parameters of the composite parameter type and generates a Boolean expression that relates two or more sub-parameters. The natural language processing system may apply the composite parameter type to determine that the pluralities of sub-parameters in an input text satisfies the Boolean expression to initiate performance of the intended action.
