UCG Grammars; the Control of their Descriptive Adequacy

, 1989
Several models of grammars were used in the ACORD project (LFG, UCG, GPSG, string grammars and CCG). Only the first two remained as the standard grammar models of the project. Furthermore, the UCG model can be understood as a general framework leaving open choices: these are represented in the English and French grammars in their several and evolving ...
