This volume contains the supplementary proceedings of ICCS 2008, the 16th International Conference on Conceptual Structures (ICCS). The focus of the ICCS conference is the representation and analysis of conceptual knowledge. ICCS brings together researchers to explore novel ways that conceptual structures can be used.

Conceptual Structures are motivated by C.S. Peirce's Existential Graphs and were popularized by J. F. Sowa in the 1980's. Over 16 years ICCS has increased its scope to include innovations from a range of theories and related Conceptual Structure practices, among them formal concept analysis and ontologies. Therefore, ICCS presents a family of Conceptual Structure approaches that build on techniques derived from artificial intelligence, knowledge representation, applied mathematics and lattice theory, computational linguistics, conceptual modeling, intelligent systems and knowledge management.

More than 70 papers were submitted to ICCS 2008 for peer review. All papers were assessed by at least three referees one of whom was an Editorial Board member who managed any necessary revisions. In 2008 ICCS adopted a two-tiered publication strategy. The top-ranked 19 papers were published in Springer's
