John F. Sowa

John Florian Sowa is a computer scientist who invented conceptual graphs[?], a graphic notation for logic and natural language, based on the structures in semantic networks and on the existential graphs[?] of Charles S. Peirce. He is currently developing high-level "ontologies" for artificial intelligence and automated natural language understanding. International conferences on conceptual graphs have been held for over a decade. Sowa combines ideas from numerous disciplines and eras modern and ancient, for example, applying ideas from Aristotle and Alfred North Whitehead to database schemas[?] theory.

He spent most of his professional career at IBM and is currently teaching at SUNY Binghamton[?].
