The potential of AI for scientific research

What if a cure for an intractable cancer is hidden within the results of thousands of clinical studies? We believe that in 20 years’ time, AI will be able to connect the dots between studies to identify hypotheses and suggest experiments that would otherwise be missed. That's why we're building Semantic Scholar and making it free and open to researchers everywhere.

Semantic Scholar is a project at the Allen Institute for Artificial Intelligence (AI2). AI2 was founded to conduct high-impact research and engineering in the field of artificial intelligence. We're funded by Paul Allen, Microsoft co-founder, and led by Dr. Oren Etzioni, a world-renowned researcher and professor in the field of artificial intelligence.
