DCG

Noun

Meaning

(computing) Initialism of definite clause grammar.
The AGFL formalism for the syntactic description of Natural Languages has been developed by the Computer Science Department of the Radboud University of Nijmegen. It is a formalism in which large context free grammars can be described in a compact way. AGFLs belong to the family of two level grammars, along with attribute grammars and DCG's: a first, context-free level is augmented with set-valued features for expressing agreement between constituents.

(computing) Initialism of discounted cumulative gain.
