Yewno Education is a unique conceptual discovery environment based not on key words and phrases but on ideas contained in full text. Formally launched at ALA this year, Yewno is a "semantic-analysis engine" that "uses a mix of computational semantics, graph theory, and machine learning to retrieve relevant documents without reliance on restrictive conventions imposed by external technology or data format requirements."
The technology is currently in beta-testing and/or trials at eight institutions: Harvard, Stanford, MIT, the University of Michigan, University of California–Berkeley, Stonehill College, Oxford University, and the Bavarian State Library.
