Algernon Tutorial

These slides provide a brief tutorial to Algernon. The user should already know a bit about rule-based reasoning and be familiar with a frame-based KBMS such as Protégé.

The tutorial slides use the Newspaper example KB that is supplied with every release of Protégé. The Newspaper KB was relatively unchanged until 7 Feb 2003 when it was extensively updated in Protégé release 1.8beta build 1030. These tutorial slides currently use the version of the Newspaper KB in use before build 1030.
