|Pack logicmoo_cg -- prolog/cgt/README|
CGT (Conceptual Graph Tools) is a partial implementation of Sowa's Conceptual Structures Theory written in Quintus Prolog, although it uses very few Quintus-specific features. It should be easily adaptable to any Edinburgh-style Prolog.
The CGT package contains the following files:
Name Size Contents
qxp.pl 5490 main file; consult and read this first can_ops.pl 19102 canonical formation rules type_ops.pl 13450 operations on the type hierarchy gen_lin.pl 21282 linear form generator rec_lin.pl 24245 linear form parser gramaux.pl 10404 tokeniser log_ops.pl 16270 propositional inference rules misc.pl 40313 DB management, referent expansions & contractions list.pl 10509 list and set operations canon.gr 3906 a canonical basis (graphs) canon.cty 3330 a canonical basis (concept types) canon.rty 1527 a canonical basis (relation types) canon.hrc 1093 a canonical basis (type hierarchy) canon.dsc 26 a canonical basis (graph descriptions) cgp_id.dat 39 a canonical basis (database keys) COPYING 17982 GNU General Public License README this file
According to the License you may not use (parts of) CGT for commercial purposes. But if you want to do so, please drop me a note and I'm sure we'll reach somee kind of agreement.
Each file begins with the following sections:
COPYRIGHT copyright, warranty, and license notice AUTHOR(S) names and addresses of all authors that contributed GENERALITIES file identification (name, creation, description, etc.) HISTORY development of the changes: version, date, author, description CONTENTS predicates exported by the file (name & description)
The rest of the file contains the code for the predicates. Each one is preceded by a comment section.
If you change the code please adhere to the following conventions:
I would also very much appreciate if you could send your changes back to me, so I may keep a master version to send regularly to everyone interested in CGT.
Anything you write (working papers, reports, articles, etc.) about your work using GET is also of great interest to me (and probably everyone else working with CGT).
Bug reports, criticisms, but not flames (I know that parts of the code are ghastly), and suggestions are most welcome.
