Knowledge Explorer - create your own knowledge base.
<P>
Knowledge Explorer is an interactive tool for organizing knowledge.
It helps the user to record, change and search knowledge, and provides
extensive error checking to ensure the internal consistency of the knowledge.
Interaction with Knowledge Explorer uses the KR language -- simple
English-like statements, commands and questions, plus UNIX-like conditionals,
loops and methods.  A smart menu interface prompts the user for all
necessary information, and automatically generates the correct input syntax.
<P>
Knowledge Explorer defines knowledge as an identification of the facts
of reality, using words and sentences.  The internal knowledge structure
consists of entity-characteristic-proposition hierarchies with space-time
dependent events.  The principal external knowledge structures are
hierarchies, relational databases and transliterated English.
<P>
Knowledge Explorer object module and knowledge base are available for
Windows 98/95/NT/3.x and Linux.
Knowledge Explorer source code is available to registered users
(shareware $25).
