From Philippe Martin --


Hi,

I have implemented a CGI server that permits to search formal terms
(categories)
in a large ontology. I initialized the ontology with the part of WordNet
relative
to nouns and adjectives.
Each term is identified by a unique identifier and has one or several names.
Conversely, a name/word is connected to several terms. The terms are
connected via
various kinds of links, e.g. subtypeOf, partOf, memberOf, substanceOf,
exclusiveWith.

The CGI server permits to search (or refer to via an URL) terms via their
identifiers,
their names or links connected to them. Results can be provided in RDF or
more
readable and CG-like formats. An HTML+Javascript interface to this CGI
server is at:
http://www.inria.fr/acacia/personnel/phmartin/kb/tsearch.html

Another CGI server and interface permit the comparison of two given terms:
http://www.inria.fr/acacia/personnel/phmartin/kb/tcomp.html

Navigation between the terms is also possible. The documentation is
accessible by
clicking on the title.


Note 1: I inserted the top-level WordNet categories into my top-level
ontology.
This permits to use 84,000 WordNet categories with the 120 basic relations
that I
defined and to support semantic checks on the uses and updates of whole
ontology.
This top-level ontology and the way the insertion has been made is
documented at:
http://www.inria.fr/acacia/personnel/phmartin/RDF/phOntology.html
A 3.5 Mb gzipped version of the whole ontology can be accessed at:
http://www.inria.fr/acacia/personnel/phmartin/kb/theKB.txt.gz


Note 2: I implemented these CGI servers on top of FastDB, a main memory
database 
management system (with transactions) that has a C++ API and similar
principles
as FramerD (http://www.framerd.org/). This generally permits immediate
answers to
the queries (at least from France; it takes 1 or 2 seconds from Australia
during
the week-end). The FastDB home page is at:
http://www.ispras.ru/~knizhnik/fastdb.html


I hope you'll enjoy these tools.  Demo at ICCS.

Philippe
