Doesn' the work on "Formal Concept Analysis "
(FCA) at Karlsruhe build concept lattices something like this?
For
exaple Philipp Cimiano, Steffen Staab, & Julien Tane tested an assumption that
:
"verbs pose strong selectional
restrictions which could be used to build a conceptual hierarchy on the basis of the
inclusion relations between the extensions of the selectional
restrictions of all the verbs. Tthe verbs themselves provide intensional descriptions for each
concept (in
"Deriving
Concept Hierarchies from Text by Smooth Formal Concept
Analysis"). They have a small concept lattice example in the
paper.
I've also seen discussion of mathematical structures
related to FCA (e.g. concept lattices, Galois connections, closure structures,
attribute implications) that seems to be something worth considering here if
people are building applications.

Gary

Seeking meaning in a pattern in the connections of your
lattice, like Google's
page-rank algorithm, which seeks meaning in the
pattern of connections
between pages on the Web.
Yes, that's
nice.
Seeking patterns in use would be one strategy. Another would be
to seek
patterns in response to a query.
Which takes me to Rich's
initiative.

Rich. Why use WordNet? Why not use words? That
way you can handle your query
"natively".
As you seek paths from
word-to-word you will travel node-to-node, and describe
a pattern in your
lattice, which can be interpreted meaningfully a bit like
the patterns of
Google's page-rank algorithm, as John
suggests.
