Conceptual Structures


Home Page

Even though there are multiple semantic network representations available, the representation that has some of the most flexibility is Conceptual Structures, CS. CS is a logic based representation of C.S. Peirce's existential graphs developed by John Sowa. In his 1984 book titled: "Conceptual Structures: Information Processing in Mind and Machine", John gives a broad range of theoretical and applied studies in linguistics, logic, philosophy, and artificial intelligence. The two most important influences on this book were the philosophers Charles Sanders Peirce and Alfred North Whitehead, who were pioneers in symbolic logic. The book stimulated an interdisciplinary community of students and researchers to organize a series of informal workshops, which in 1993 were upgraded to the annual International Conferences on Conceptual Structures (ICCS).

The founding community focused on the theory and applications of Conceptual Graphs (CGs), with a website which showed graphical diagrams that were built out of the logic building block of conceptual structures. However, later they were joined by another community devoted to Formal Concept Analysis (FCA), which is the title of a book written in 1996 by Bernhard Ganter and Rudolf Wille. The combined communities welcome anyone working in any area of cognitive science, especially on aspects of the analysis and representation of concepts and their expression in language and logic. They are also working together on collaborative testbeds, such as PORT, to develop users-technologists partnerships, and are working on building a new web site that is current for CGs.

In relationship to the Charles S. Peirce connection to the group, the beginnings to the ConStructPeirce Project is begin designed at the ConStructPeirce Workshop, July 20-21, 2014, for digitizing the Peirce manuscripts.
