[Corpora-List] Definition of Lexical database

[Jose Maria Gomez Hidalgo]

Dear all

 From the answers to my previous posting about LDBs, the following quesion 
raised: what is a lexical database?

It seems that the general opinion is that a LDB is a repository of lexical 
semantic information that:

- in contrast to MRDs, is oriented to be used by programs rather than persons
- in contrast to Knowledge bases and ontologies, is lexically oriented and 
does not support reasoning in a explicit way (that is, with tools)
- in contrast to NL applications lexicons, is of general purpose and not 
NLP oriented

These points are not clear, because:

- Current MRDs have programming interfaces
- Many KBs are currently being used in text classification and so, have 
been partially lexicalized, and several reasoning techniques have been 
designed on LDBs (seeing them as semantic networks or ontologies)
- Some Lexicons highly overlap with LDBs (or maybe are!) in contents and 
structure

A canonical definition of a LDB? A survey paper or institutional white 
paper describing what is a LDB?

A very good reference from the point of view of NLP is the EAGLES IG on 
lexicons report (Preliminary Recommendations on Lexical Semantic Encoding) 
available at http://www.ilc.pi.cnr.it/EAGLES/EAGLESLE.PDF, but it does not 
define LDBs

This message may promote discussion on the topic (I think definitions may 
be quite open, and not satisfactory for all). But the goal is a concrete 
definition (if possible).

Best regards and thank you in advance
