Welcome to the home page of the Classification Society. In 2008, the Classification Society of North America (CSNA) reverted to its former name. The Classification Society is a nonprofit interdisciplinary and international organization whose purposes are to promote the scientific study of classification and clustering (including systematic methods of creating classifications from data), and to disseminate scientific and educational information related to its fields of interests.

• The 2018 Workshop on Model-Based Clustering and Classification, MBC2 2018, will be held in Catania, Italy from September 5-7, 2018.
