Re: SUO: WordNet Mappings




Hi Ian,

thanks for the mapping paper: will read with interest.

well, linguistically it is well known that one of the functions
of nominalisations is to drop a lot of information--e.g., information
about their temporal profile, their configuration of participants/semantic
roles, aspect, and so on--so, at least from my own background
in Natural Language Generation, we stick to events (and the verbal configurations
that express them) as the basic starting point and if justified (from
their use in a text) we can throw away a lot of information and use
a noun, since most nouns behave pretty much the same. This is just to
adopt an event semantics as "basic" whenever we can.

well, again, it might have done if, as you say,

but they don't. This is probably another reason for moving on to the
EuroWordNet upper structure rather than WordNet. I think these things 
have been thought of there more.

There is also the question about the hierarchies of the synsets concerned
with verbs and those concerned with nouns: I think (haven't looked at
these for a while now) these look very different in WordNet, so there
is some different information being taken into consideration.

This is a relief! :-)

Clearly a lot of interesting stuff here: and a link to WordNet, for all
its (i.e., WordNet's) drawbacks, is obviously a Good Thing. I look forward to
more. There have been some moves to using WordNet information as a lexical
resource for doing Natural Language Generation--I think having a link to
something that is better organised, like the SUMO-to-be, will be a great
help.

Best,
