Good book: The Definitive Guide to Plone; my AI products
I have not updated my KBtextmaster product in a while. Starting in December, I am scheduling my time to finish off the version 2 functional improvements (better automtic categorization, better identification of proper names like people, places, products, and automatic generation of RDF for a few selected ontologies).
Very high quality knowledge and document management systems are now available for free as open source projects. My plan (interupted by a fun full time 6 month consulting project) is to position the KBtextmaster as an optional add-in tool for people building knowledge management systems.
KBtextmaster is written in Common Lisp and version 2 will only be available as a compiled executable built with LispWorks.
