Algernon Tutorial 1.h
These exercises and examples use the newspaper project included
in the examples folder of your Protege installation.
Warning! Algernon can modify your KB. Practice on a test KB or a copy of your
real KB until you are proficient with Algernon.
Start Protege, go to the Algernon tab, and type these into the Algernon input box:
- ((name instance_00068 ?name)) Returns "Ms Gardiner"
- ((:CLEAR-RELATION instance_00068 name)) Removes Ms Gardiner's name
You can view the instances of Editor in the Protege browser to verify that the name slot in instance_00068 is now blank.
- ((name instance_00068 "Michael Jordan")) Changes the name to "Michael Jordan"
You can view the instances of Editor in the Protege browser to verify that "Michael Jordan" is now an Editor.
- ((name instance_00068 ?name)) Repeat the original query
