Knowledge Organization (KO) has its roots in the fundamental human need to understand and interact with the environment. 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.


NEW!  We are pleased to introduce Knowledge Organization Education (KO-ED), a new series of virtual classes which should be of interest to all who want to learn, refresh or expand their understanding of knowledge organization principles and processes. See details here
