Conceptual graph
From Wikipedia, the free encyclopedia
John F. Sowa's conceptual graphs (CGs) are a system of logic based on the existential graphs of Charles Sanders Peirce and the semantic networks of artificial intelligence. They express meaning in a form that is logically precise, humanly readable, and computationally tractable. The graph-based model, expressivity, and intuitiveness of CGs has led to their use as an intermediate language for translating computer-oriented formalisms to and from natural languages. With their graphic representations, they serve as a readable but formal design and specification language. CGs have been implemented in a variety of projects for information retrieval, database design, expert systems, and natural language processing.

There is a lively worldwide conceptual graphs research community. The community usually meets at the International Conferences on Conceptual Structures (ICCS) which have been held annually in Europe, Australia, and North America since 1993. The following is a sample listing of currently active researchers on conceptual graphs:
