What: Kim Gerdes, visiting us from U. Paris 7, will give a talk on a
metagrammar approach to producing a TAG grammar for German. Abstract follows.
A German Metagrammar
- Kim Gerdes
Even though a full German grammar is beyond the (derivative) generative
capacity of Tree Adjoining Grammars, a German TAG can be useful for tasks
where not all possible word orders are needed, i.e. for generation. My trip
takes me from Scylla to Charybdis, when trying to join correct derived and
derivation trees while producing a useful generation grammar. The use of a
metagrammar will be shown to be enchanting but problematic: M.H. Candito's
metagrammar compiler was closely linked to the grammar she wanted to produce
and cannot easily be adapted to my goals, and the new compiler written by
Bertrand Gaiffe is running but still in alpha state. However, the resulting
trees can be used for limited purposes, and the experience gathered on the way
may help avoid some cliffs when designing a Tree Adjoining Grammar for a new
language.
