Semantic Scholar is a free, AI-powered research and discovery tool dedicated to accelerating scientific breakthroughs. It indexes over 226 million academic papers across all disciplines, using advanced machine learning and natural language processing. The platform extracts meaning and identifies key connections in scientific literature, enabling scholars to efficiently overcome information overload and develop a comprehensive understanding of their fields. Created by the Allen Institute for AI (AI2), Semantic Scholar champions open technology and resources, offering tools and datasets, including olmOCR, Ai2 ScholarQA, S2ORC, and the Semantic Scholar Academic Graph (S2AG).
