In a conceptual model for knowledge bases the data and knowledge are represented formally as "items". The foundation of this model is a "basis" consisting of data items. "Objects" are "item building" operators that are applied to the basis to build the information items and knowledge items in the conceptual model. Objects may be decomposed. In this way the knowledge in the resulting conceptual model is simplified. Knowledge object decomposition removes hidden and unwanted relationships from the knowledge base.
