[Corpora-List] automatic definition construction/retrieval

[Martin Krallinger]

Dear all,

I wonder if anybody could provide me with some advice related to tools 
or references related to the:

1) automatic construction of dictionary-like definitions of terms 
extracted automatically from free text articles, or alternatively

2) the retrieval of sentences which are likely to describe definitions 
of terms within documents would also be appreciated.

For instance a domain specific example could be :
[HpaB] : HpaB is a protein which promotes the secretion of a large set 
of effector proteins and prevents the delivery of non-effectors into the 
plant cell.

I am actually aware of the following reference:

@Article{ Riloff:1993,
     author = {Riloff,E.},
     title = {{Automatically Constructing a Dictionary for Information 
Extraction Tasks.}},
     journal = { Proceedings of the Eleventh National Conference on 
Artificial Intelligence.},
     pages = {811--816},
     year = {1993},
}


Thanks for any advice and best regards,


Martin Krallinger
