  • Publication number: 20250259021
    Abstract: Techniques for executing system actions during conversations between a human user and an autonomous conversational system are disclosed. A first generative language model processes user messages to determine user intent, while a dialog management model analyzes the intent and conversation context to identify required system actions. The system executes actions by retrieving parameters from context, performing database queries or API calls to obtain response data, and storing results in conversation context variables. A second generative language model generates natural language responses using the action results. The system maintains conversation context including message history, action results, and state information, validates action execution, and initiates human agent handoff when needed. The system improves over time by detecting poor performance, gathering problematic conversations, and retraining using updated configurations.

  • Publication number: 20250259022
    Abstract: Techniques for analyzing conversation logs to identify system actions for an autonomous conversational AI system are disclosed. Historical conversation logs are analyzed using a generative language model to identify conversation topics and subtopics. Conversations within each topic and subtopic are ranked based on frequency of occurrence and representative conversations are selected using normalized mean conversation embeddings. The selected conversations are analyzed to identify opportunities for system actions, and user messages and human agent responses are converted into system actions using a transformer-based natural language processing model. An action configuration comprising the identified system actions and required parameters is generated and stored for training the autonomous conversational AI system.

  • Publication number: 20250238636
    Abstract: Techniques for analyzing conversation logs to identify system actions are described. Historical conversation logs are analyzed using a generative language model to identify conversation topics and subtopics, with conversations ranked by frequency and selected using normalized mean conversation embeddings. The system converts user messages and human agent responses into system actions using a transformer-based natural language processing model, generating database queries and API calls with required parameters. The system creates a graph structure representing conversation flows, identifies action nodes, determines required parameters, and validates the structure. An action configuration is generated and stored for training an autonomous conversational AI system. The system preprocesses logs to normalize data across channels, anonymizes personal information, and automatically improves performance by analyzing problematic conversations.

  • Patent number: 12282743
    Abstract: Described herein is an Autonomous Conversational AI system, which does not require any human configuration or annotation, and is used to have multi-turn dialogs with a user. A typical Conversational AI system consists of three main models: Natural Language Understanding (NLU), Dialog Manager (DM) and Natural Language Generation (NLG), which requires human provided data and configuration. The system proposed herein leverages novel Conversational AI methods which automatically generates conversational AI configuration from any historical conversation logs. The automatically generated configuration contains Auto-Topics, Auto-Subtopics, Auto-Intents, Auto-Responses and Auto-Flows which are used to automatically train NLU, DM and NLG models. Once these models are trained for given conversation logs, the system can be used to have dialog with any user.

  • Publication number: 20240311399
    Abstract: An interactive entity relationship diagram discovers explicitly defined relationships, and also dynamically discovers and represents non-explicit relationships. This entails calculating metadata and references by parsing the queries. An entity relationship diagram thereby provides novel visibility on the queries being related as the basis for a user interface which integrates several configuration utilities.

  • Patent number: 10535070
    Abstract: To assist in patent searching a description includes a consumer purchasing behavior profiling system having aspects including consumer profiles formed and updated based on a variety of data. Advertisers access to send targeted advertising messages to the consumers. Aspects include advertising information together with incentive level and mix being correlated with the consumer profile to produce a measure of the applicability of the ad to that consumer and the probability of converting that consumer. Other aspects include determining the mix of ad information, incentive level and type, and product offering that will be required to convert an ad viewer to a buyer. Aspects focus on using wireless devices with consumers. Other aspects reside in methods of using electronic coupons distribution and redemption to collect additional data points necessary to understand the consumer's purchasing decision process and factors that influence the purchasing decision.
