It can be a noun or adjective or any word acting as a noun or adjective. Thus, it is useful to have a way to talk about that specific part of the knowledge base.

The more operators one includes in a logic and the more complicated the T-box having cycles, allowing non-atomic concepts to include each otherusually the higher the computational complexity is for each of these problems see Description Logic Complexity Navigator for examples. Description logic is related to—but developed independently of— modal logic ML.

Previous to this it was called chronologically: Expressiveness and tractability in knowledge representation and reasoning Hector J. Not having UNA means that two concepts with different names may be dith by some inference to be shown to be equivalent. Showing of 16 references. This paper has highly influenced other papers.

Other constructors have no corresponding construction in FOL including restrictions on roles for attribufive, inverse, transitivity and functionality. It is shown that deciding coherence and subsumption of such descriptions are PSPACE-complete problems that can be decided with linear space. Dataspaces Hyperdata Linked data Rule-based systems. In that sentence, “daughter” attribytive the direct object and “Natasha” is the object complement, which renames or describes the direct object.
