"just-in-time" sub-grammar extraction

[Vlado Keselj]

Hi,

I am looking for relevant work, and ideas, regarding the following
practical problem in HPSG parsing:

Given a large HPSG grammar and a short piece of text (a sentence, a
passage, or even a document), efficiently extract a small HPSG sub-grammar
(out of the larger one) that gives the same parsing and partial parsing
(chart edges) results.  This would improve the parsing speed.
