Conceptual structures provide a logically sound medium for knowledge representation and reasoning, and have been applied in natural language processing, information systems modeling, program specification, information retrieval, machine learning and case based reasoning. The denotation of conceptual structures is called conceptual graphs which have been developed from the existential graphs of C. S. Peirce and semantic networks. Conceptual graphs are bipartite, consisting of nodes which represent concepts and nodes which represent relations. Each concept node is labeled with a type and may have a referent. The concept types are organized in an is-a hierarchy. Relation nodes are also typed. Further information on conceptual structures and their denotation can be found at http://concept.cs.uah.edu/CG/.

The International Conference on Conceptual Structures is the annual conference and principal forum on the theory, application and implementation of conceptual structures. ICCS’99 is the fourteenth annual meeting which begin in 1986 with a series of seven workshops. The organizers and program committee of ICCS’99 are pleased to offer an excellent program selected from submissions by researchers in the growing international community. For current information on ICCS’99, please see our web page http://www.ee.vt.edu/~iccs99/.

The ICCS proceedings are published in the Springer-Verlag Series: Lecture
Notes in Artificial Intelligence.
