We are a not-for-profit scientific/professional association dedicated to promoting the theory and practice of Knowledge Organization. We categorise, distinguish, name and relate things in ways that are meaningful and useful, and help us learn.  We deploy classification, indexing, taxonomies, data mining, semantic analysis, linked data, and other emerging technologies to reveal patterns and make sense of the knowledge landscape. KO adds intelligence and value to the representation, processing, storage and transfer of information. Read more here and see our programme of events below.
