Tbox

From Wikipedia, the free encyclopedia

In Computer Science, a TBox is an "terminological component" - a vocabulary associated with a set of facts ABox.

The terms ABox and TBox are used to describe two different types of statements in ontologies. TBox statements describe a system in terms of controlled vocabularies for example a set of classes and properties. ABox are TBox-compliant statements about that vocabulary.

TBox statements tend to be more definitional in nature such as a dictionary of words.

TBox statements are sometimes associated with object-oriented classes and ABox statements associated with instances of those classes.

Together ABox and TBox statements make up a knowledge base.
