A hackathon project called OlympicRAG explored the effectiveness of different question-answering pipelines using TigerGraph. The project compared a standard Retrieval-Augmented Generation (RAG) approach, a GraphRAG method that leverages graph structures, and an Agentic GraphRAG system. The Agentic GraphRAG, which uses specialized agents for tasks like entity linking and multi-hop reasoning, proved to be the most cost-effective per correct answer and ensured all its responses were supported by cited evidence. However, all pipelines struggled with counting questions, with the LLM often miscounting even when relevant data was provided. AI
IMPACT Demonstrates the trade-offs between cost, accuracy, and evidence-backing for different LLM query architectures.
RANK_REASON The item details a comparative study of different AI question-answering techniques applied to a specific dataset and platform. [lever_c_demoted from research: ic=1 ai=1.0]
