Message 1: debugging computational grammars

Subject: debugging computational grammars

Dear colleagues,

I'm looking for references to the problem of developing and debugging
computational grammars for natural languages. I'm particularly
interested in tools and approaches used in debugging grammars
(particularly in their use when dealing with relatively large
hand-written grammars). In the computational systems I'm aware of,
usually there is only a limited (and standard) set of debugging tools:
tracers, steppers, chart browsers.

Furthermore, does anybody know any extensive study on the most
suitable strategies/tools to cope with the writing/testing/debugging
cycle (always with a particular emphasis on debugging)?

I know that there have been hints to this problem in related areas
(e.g., the EU projects TSNLP and DiET, some papers at the ACL-EACL97
workshop on Computational Environments for Grammar Development and
Linguistic Engineering) but it seems to me that this topic has so far
received little attention. But perhaps I'm missing some relevant
contributions and so I'm asking for your help.

Apart from references to relevant stuff, I'm also interested in your
general opinion on the issue. Is this (alleged) lack of interest an
indication of the fact that such issue is in your opinion not
particularly relevant?

I'll post a summary if I receive enough responses

Message 2: Survey on Description Logics/Concept Languages in NLP

Subject: Survey on Description Logics/Concept Languages in NLP

Hi everybody.

I'm in charge of writing a survey chapter on the role in NLP of
Description Logics (aka Concept Languages, Terminological Logics,
Frame-Based Description Languages, KLONE-like languages) in the
forthcoming Description Logics Handbook (Cambridge University Press).

Any pointer, reference, help on the topic is appreciated, since I may
have missed some important work! 
A QUICK answer is mostly appreciated, since I'm finalising the
chapter, which should be ready very soon.
