The International Conferences on Conceptual Structures (ICCS) focus on the formal analysis and representation of conceptual knowledge, at the crossroads of artificial intelligence, human cognition, computational linguistics, and related areas of computer science and cognitive science. The ICCS conferences evolved from a series of seven annual workshops on conceptual graphs, starting with an informal gathering hosted by John F. Sowa in 1986. Recently, graph-based knowledge representation and reasoning (KRR) paradigms are getting more and more attention.  With the rise of quasi-autonomous AI, graph-based representations provide a vehicle for making machine cognition explicit to its human users.  The aim of the ICCS 2019 conference is to build upon its long standing expertise in graph-based KRR and focus on providing modelling, formal and application results of graph-based systems.

ICCS 2019 will be held in Marburg, at Marburg University.
