While searching for something to do my final project for my
Artificial Intelligence class,
Ben was busy getting the
RoverWeb up and running.
I glanced thru one the FAQ pages
and realized that it was hard to figure
out what kind of Land Rover I was looking at. In other
words, there were many more kinds of Land
Rovers than I had previously realized. So here was the
idea for my final project: Build an Expert System that would
ask questions and figure out what kind of Land Rover the
user was looking at. Of course, I didn't want to type
the answers to the various questions, and I wanted to put
it on the Web to help Ben out. So here is the Web
version of the Identa-Rover program. Enjoy!
You want to know how I did it?
is my final project paper submitted to the
Cal State Chico
CSCI 223 Artificial Intelligence
class. If you don't want
to burrow thru the paper, I used
to create the expert system (ES) that actually asks the question,
checks the answers, and provides the results. I originally used the
to interface to the expert system. But this didn't work out for
some weird reason and I had the use Tcl bidirectional pipes.
The Tcl script is also a
script -- it gets called thru the web server from web pages,
notably this page and the other question pages. By keeping
track of the previous answers, the Tcl script can run the
ES and get the next question, which is then returned to your
web browser. Cool, huh?
What's it Got?
Currently the ES contains 12 Land Rovers. These are most
everything except the Discovery, Forward Control, and
Range Rover models (we hope to add these later...) There are
10 questions which are asked, unless a single match is made
earlier. This ES is specially setup to handle "Don't Know"
answers, in the event that a good answer can't be determined.
This has proven to be one of its best features, in case one
is looking at a photo or running the ES from memory and can't
remember a specific. The question pages also show which
Land Rover match so far, and provides a way to "Backtrack"
to a previous question, which is useful for exploring the
ES's knowledge base. For more info on the
