[Fwd: Re: [Corpora-List] automatic definition construction/retrieval]

[Carlos Rodriguez]

Hi Martin,

I don't know if Riloff's work will be useful to you, if you are looking 
for classic, lexicographic definitions, since she works on Information 
Extraction "dictionaries", or sets of useful extraction patterns for 
specific tasks. If you are loking foe metalinguistic patterns, see below.
For a good description of definitional contexts, see:

Pearson, J. (1998) /Terms in Context./ Studies in Corpus Linguistics. 
John Benjamins. Amsterdam

Two lines of work that are actual implementations come to mind, one by 
Klavans, J. and Muresan, S. (2001) Evaluation of the DEFINDER System for 
Fully Automatic Glossary Construction, /Proc. Am. Med. Inf. Ass. //Symp./

The other, my own: Rodríguez, C. (2004)  Metalinguistic Information 
Extraction for Terminology,/ 3rd International Workshop on Computational 
Terminology/ (CompuTerm 2004) Coling, Geneve 2004.

Good luck
