The Norwegian Bokmål computational grammar NorGram, now also extended to Nynorsk, has been under development since 1999 as part of the long-term international Parallel Grammar Project (ParGram). The ParGram grammars are developed within the framework Lexical-functional grammar (LFG) on the computational platform Xerox Linguistic Environment (XLE). An LFG grammar assigns two representations to each reading of a sentence, a c-structure (a phrase structure tree) and an f-structure (an attribute-value graph).
