About Us

Diffeo grew out of the Text Retrieval Conference Knowledge Base Acceleration project (TREC KBA), which Diffeo organized for the National Institute of Standards and Technology (NIST), and DARPA Memex. TREC KBA evaluated algorithms for helping people discover new knowledge to add to a knowledge base like Wikipedia.

Diffeo Engine

The hierarchical tree graph structure illustrates how Diffeo's cross-document cross-lingual interactive entity disambiguation algorithms help users discover new knowledge.

Cloud Search

Cloud Search began with a Desktop that looked like this. Jason was helping his mom track down some of her files (and failing). She had 356 files on her Desktop alone, and was constantly creating and receiving more. We built a search tool to solve her problem.

Our Partners

Diffeo cultivates partnerships with technology and providers. Diffeo's platform includes Basis Technology's Rosette Linguistics for named entity recognition in seventeen languages. Diffeo's Advanced Discovery Toolbox includes news publications in many languages for Lexis Nexis' Moreover service
