Which institute released Semantic Scholar in 2015?

The Allen Institute for AI released Semantic Scholar in 2015.

Semantic Scholar is an artificial-intelligence-powered search service for scientific literature. It was developed by the Allen Institute for Artificial Intelligence, usually abbreviated AI2, a nonprofit research institute founded by Microsoft co-founder Paul Allen. The service was publicly launched on November 2, 2015.

At launch, Semantic Scholar concentrated on computer-science papers and searched more than three million publications. Its goal was not merely to match keywords, but to use natural-language processing, machine reading, and computer vision to identify useful concepts, influential papers, citations, and connections between research topics.

The service later expanded beyond computer science. Biomedical literature was added in 2017, and its coverage eventually broadened across scientific disciplines. Features such as automatically generated summaries, citation context, paper recommendations, and author or topic connections distinguish it from a basic document index.

A common mix-up is attributing Semantic Scholar to a university or to Google Scholar. Google Scholar is a separate Google service; Semantic Scholar is an AI2 project.
