GraphEval36K: Benchmarking Coding and Reasoning Capabilities of Large Language Models on Graph Datasets
This addresses the problem of evaluating and enhancing LLMs' graph reasoning capabilities for AI and data science applications, though it is incremental as it builds on existing benchmarking efforts.
The paper tackles the limitations of large language models (LLMs) in handling structured graph data by introducing GraphEval36K, a comprehensive benchmark dataset with 36,900 test cases, and finds that private models outperform open-source ones while proposing a method that improves performance by up to 29.28%.
Large language models (LLMs) have achieved remarkable success in natural language processing (NLP), demonstrating significant capabilities in processing and understanding text data. However, recent studies have identified limitations in LLMs' ability to manipulate, program, and reason about structured data, especially graphs. We introduce GraphEval36K, the first comprehensive graph dataset, comprising 40 graph coding problems and 36,900 test cases to evaluate the ability of LLMs on graph problem-solving. Our dataset is categorized into eight primary and four sub-categories to ensure a thorough evaluation across different types of graphs. We benchmark ten LLMs, finding that private models outperform open-source ones, though the gap is narrowing. We also analyze the performance of LLMs across directed vs undirected graphs, different kinds of graph concepts, and network models. Furthermore, to improve the usability of our evaluation framework, we propose Structured Symbolic Decomposition (SSD), an instruction-based method designed to enhance LLM performance on complex graph tasks. Results show that SSD improves the average passing rate of GPT-4, GPT-4o, Gemini-Pro and Claude-3-Sonnet by 8.38%, 6.78%, 29.28% and 25.28%, respectively.
