Introduction

The paper introduces AGENTiGraph, an interactive knowledge graph platform that integrates large language models (LLMs) with knowledge graphs to enhance question-answering capabilities, particularly for complex, domain-specific tasks.

Key Points

• AGENTiGraph employs a multi-agent architecture to dynamically interpret user intents, manage tasks, and integrate new knowledge, ensuring adaptability to evolving user requirements and data contexts.

• The system provides a natural language-driven interface that simplifies complex knowledge graph operations, enabling user-friendly interactions.

• Experiments demonstrate the effectiveness of AGENTiGraph, achieving 95.12% accuracy in user intent identification and a 90.45% success rate in task execution, outperforming state-of-the-art zero-shot baselines.

• User studies validate the system's efficiency, with participants highlighting its ability to deliver concise, focused answers and effectiveness in complex knowledge management tasks across diverse domains.

• AGENTiGraph has been extended to the legal and healthcare domains, showcasing its versatility in constructing specialized knowledge graphs capable of answering complex queries.

Methodology

AGENTiGraph is designed with a multi-agent system that provides intuitive interaction between users and knowledge graphs. Each agent specializes in a specific task, such as interpreting user intent, extracting key concepts, planning tasks, interacting with the knowledge graph, and generating responses.

Results and Findings

The evaluation of AGENTiGraph shows that it significantly outperforms state-of-the-art zero-shot baselines in both task classification accuracy (up to 95.12%) and task execution success rate (up to 90.45%). The user studies further corroborate the system's effectiveness in real-world scenarios, with participants highlighting its ability to deliver concise and focused answers.

Implications and Conclusions

AGENTiGraph represents a paradigm shift in how humans interact with and harness the power of knowledge graphs for complex data management and analysis tasks. The system's adaptive and user-friendly approach, coupled with its superior performance, demonstrates its potential to revolutionize the field of knowledge graph interaction and enhance the integration of LLMs with structured knowledge representations.
