Advanced artificial intelligence (AI) systems with access to millions of research papers could inspire new research ideas that may not be conceived by humans alone. However, how interesting are these AI-generated ideas, and how can we improve their quality? Here, we introduce SciMuse, a system that uses an evolving knowledge graph built from more than 58 million scientific papers to generate personalized research ideas via an interface to GPT-4. We conducted a large-scale human evaluation with over 100 research group leaders from the Max Planck Society, who ranked more than 4,000 personalized research ideas based on their level of interest. This evaluation allows us to understand the relationships between scientific interest and the core properties of the knowledge graph. We find that data-efficient machine learning can predict research interest with high precision, allowing us to optimize the interest-level of generated research ideas. This work represents a step towards an artificial scientific muse that could catalyze unforeseen collaborations and suggest interesting avenues for scientists.

使用超过58百万科学论文构建的知识图谱，并结合GPT-4接口生成个性化研究想法的SciMuse系统，通过与马克斯·普朗克研究所的100多位研究团队领导的大规模人工评估，我们发现数据高效的机器学习可以高精度预测研究兴趣，从而优化产生的研究想法的兴趣水平。这项工作是朝着一种人工科学启发的方向迈进，可以催生意料之外的合作，并为科学家提供有趣的研究方向。
