Grammar development time/effort
+ are developers more open-minded to automatic (at least non-traditional) methods of grammar dev
Bart: A good grammar takes immense amounts of effort
+ by the time the grammar is developed, perhaps our formalism will be deprecated?
Antske doesn't think it's an issue. MRS is more important than HPSG (maybe)
+ Also, treebanks that are formalism-dependent similarly have limited value
+ Perhaps we need a less specific "standard" for our treebanks, resources
Francis: but that results in less interesting information
+ DELPH-IN has not pushed the point that depth-of-coverage is useful (compared to breadth)
+ How do we get to high-depth & high-coverage while producing something also useful at intermediate stages

breadth
Antske: HPSG treebanks (and MRS) can be converted to other formalisms, so maintains usefulness
Regarding grammar induction
Yi: more advanced methods can be applied (data-driven)
Bart: Laurie brought up using robustness rules for error detection, etc. This is data-driven but not necessarily statistical
Discussion of uses of bilingual text:
Francis: disambiguation (e.g. prepositions, noun-verb in Japanese-English)
also for improving coverage (e.g. ERG can parse more of a bitext than Jacy, Jacy developer can look at semantics from ERG output, use to inform Jacy development)
Talk about shared resources/standards
... about grammar development time being the bottleneck
... about the walls of reaching + (in chart above)
... about using dependency treebanks to thin trees when treebanking
+ Not always about finding funding for grammar development, but a grammar developer
Plans for future grammars:
Francis wants to find a student for Malay
Yi says Mandarin will be developed at Saarbruecken (perhaps starting at S and climbing to +)
Tania says the slavic languages will be further expanded (Polish, Russian...)
What are 'goals' of a grammar?
Of course, one is applications
One could be learning about/describing grammar (as opposed to just parsing)
