Semantic Scholar is a free, AI-powered research tool from the Allen Institute for AI that helps scholars search and discover relevant scientific literature across all fields.
About
Semantic Scholar is a free, AI-powered research tool for scientific literature, developed and maintained by the Allen Institute for AI (Ai2). It addresses a core problem for scholars: the sheer volume of published research makes it difficult to find the papers that actually matter for a given question.
The service lets users search a corpus of hundreds of millions of papers spanning every scientific discipline, and applies natural language processing to interpret the meaning of papers rather than matching keywords alone. Alongside the public search interface, Semantic Scholar offers a developer API for building scholarly applications and an augmented reading experience called Semantic Reader, which is available in beta for select papers. The project is based at Ai2 and is offered at no cost to researchers and developers.
