  7. NLG-Grammars share interesting properties with other kinds of grammars - i.e., grammars for other purposes and users - but they also bring with them several important additional properties that may prove to be highly advantage.

  8. Crucial properties of appropriate linguistic resources • wide-coverage • generality • multi-register • multi-situation • text-oriented generation grammars need to show a closer resemblance to descriptive reference grammars than to ‘theoretical’ grammars

  14. Testing and Maintenance: Example Sets

  15. Grammar development and documentation: Example Sets • large grammars are complex and difficult for newcomers to understand • this difficulty can be eased by providing example sets (‘test suites’, ‘exercise sets’) that show how particular sentences are generated using a grammar

  16. How to keep a large grammar ‘working’? • Example sets...

  17. New forms of reference grammars for the 21st. Century ...will need: • to support a variety of readings by a variety of readers • to support a variety of uses • to support links not just to exemplifying texts but also to flow-through corpus • to support arguments and alternatives by making it possible to trace through the description Matthiessen & Nesbitt (1996)

  18. Synergies for the future • The production and management of large-scale linguistic resources (LE) requires solutions to tasks that are also found elsewhere: • management of test suites and examples: best of all, drawn from corpora • using the organisation of the linguistic description to organise its documentation: descriptive and reference grammars • contrastive linguistics and multilingual descriptions
