Decision Knowledge Trees
Decision trees are often related to dichotomy (a division or
the process of dividing into two mutually exclusive or contradictory
groups). Dichotomous keys are often available to help non-experts
diagnose a particular problem. Because of the ease-of-use and
structured format of a dichotomous key, K-Vision approaches knowledge
acquisition in the same way.
K-Vision uses what could be called a multi-dichotomous
key or a decision tree. The difference between how K-Vision
and a conventional dichotomous key work is that the Knowledge
Engineer (KE) can have more than two paths from a preceding step,
and answers are not limited to YES and NO. Certain actions can
also be executed, such as displaying a picture or playing a video
clip to show the user how to execute an important step in a procedure.
K-Vision also allows for "custom" and "numeric"
K-Vision uses decision trees to quickly and easily build Decision Support
Expert Systems. K-Vision decision trees are developed with ease on the
screen in front of you. Thus, you can readily identify branches
that need responses and build the appropriate solutions.
Keeping track of your activity while working within the tree
is easy, as the cursor changes design with each type of action.
Zoom in and zoom out commands allow you to view all of the tree
or only the portion on which you are currently working.
Questions, conclusions, actions, help tasks, or procedures
can be added to the end of the answer line to represent the next
step in the tree when that particular answer is chosen. It is
easy to keep track of the different steps, as each type of step
is represented by a particular geometric shape. An answer line
without a step attached represents incomplete knowledge and visually
prompts you to build a conclusion.
