MetaboT: An LLM-based Multi-Agent Frameworkfor Interactive Analysis of Mass SpectrometryMetabolomics Knowledge Graphs
Researchers have developed MetaboT, an open-source multi-agent framework utilizing Large Language Models (LLMs) to simplify the analysis of mass spectrometry-based metabolomics data. This framework translates natural language queries into SPARQL queries for metabolomics knowledge graphs, overcoming the steep learning curve associated with specialized query languages. MetaboT employs a modular architecture with specialized agents to validate scope, resolve entities, generate schema-aware queries, and interpret results, mitigating common LLM limitations like hallucination and schema non-compliance. The system was validated on the Experimental Natural Products Knowledge Graph (ENPKG) using an expert-authored benchmark, demonstrating its effectiveness in answering complex questions about plant-metabolite relationships and biological activities.
