Solution Overview

Problem

Managing complex, unstructured communication in scenarios where correspondence is routed to different personnel can be inefficient, leading to improper distribution and increased workload for human support agents, especially in knowledge businesses like technical support, where routine queries overwhelm experts.

Innovation Solution

An autonomous large language model (LLM)-based agent is trained using question-answer threads from electronic messages to handle routine queries, freeing up human experts for complex issues, by preprocessing messages and fine-tuning the model to understand specific business contexts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If human support personnel manually handle all incoming queries, then the quality of support can be maintained, but the workload and time consumption increase significantly

Engineering Contradiction:
Improvesupport qualityVSAvoidtime consumption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

An autonomous LLM-based agent is introduced as an intermediary between users and human support personnel. The agent handles routine queries autonomously by processing electronic messages, determining questions, generating answers, and routing inquiries appropriately. This intermediary layer filters and pre-processes communications, allowing human experts to focus on complex issues while maintaining support quality and reducing their time consumption.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If all queries are routed to human experts, then accurate answers can be provided, but the distribution efficiency decreases and routine tasks overwhelm specialists

Engineering Contradiction:
Improveanswer accuracyVSAvoiddistribution efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system implements self-service capabilities where the autonomous agent independently processes electronic messages, extracts questions, generates appropriate answers using LLM technology, and routes inquiries to the correct recipients. The agent can handle routine queries autonomously without human intervention, while automatically escalating complex issues to human experts. This self-service approach improves distribution efficiency by intelligently routing queries while maintaining answer accuracy through appropriate escalation paths.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If manually created training data is used to train the LLM agent, then the training precision can be controlled, but the time and resource requirements increase

Engineering Contradiction:
Improvetraining precisionVSAvoidtraining time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

Instead of manually creating training data, the system copies and utilizes existing electronic messages from the messaging pipeline as training data. The agent training module processes real message examples, preserving the natural language patterns and query-answer structures already present in the organization's communication history. This copying approach maintains training precision by using authentic examples while dramatically reducing the time and resources required for manual data creation.

Inventive Principle:
Principle #26Copying

AI summary

The technology provides an approach to fine-tune an autonomous large language model (LLM)-based agent for question-answering in an electronic messaging context. This approach can include obtaining incoming electronic messages that each include a question, and obtaining responsive electronic messages that each include an answer to the question. The system correlates each responsive electronic message with a given incoming electronic message as a question-answer thread. The question-answer thread can be routed for each message pair to an agent training module, which performs training of an LLM using a set of the questions-answer threads as inputs to learn an answer that addresses the question. The resultant trained LLM can then be stored in a database of the system. Then, when an incoming electronic message with a question is received from a user, the trained LLM can generate a responsive electronic message according to the learned answer that addresses the question.
