Description logic (DL) is a family of formal knowledge representation languages. It is more expressive than propositional logic but has more efficient decision problems than first-order predicate logic.
DL is used in artificial intelligence for formal reasoning on the concepts of an application domain (known as terminological knowledge). It is of particular importance in providing a logical formalism for ontologies and the Semantic Web. The most notable application outside information science is in bioinformatics where DL assists in the codification of medical knowledge.

Famous quotes containing the words description and/or logic:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“Somebody who should have been born
is gone.
Yes, woman, such logic will lead
to loss without death. Or say what you meant,
you coward . . . this baby that I bleed.”
—Anne Sexton (1928–1974)
