Eliza Demo

Here’s a link to the Eliza demo we reviewed in class.  http://chayden.net/eliza/Eliza.html

You must have a Java enabled browser to run the demo.

Eliza was developed a long time ago and is primitive by today’s standards.   But it can give you some insights related to Expert Systems.  Look for the accumulation of knowledge as you interact with Eliza and the use of the knowledge later in the conversation.

How to submit project 1

Project 1 is due on Thursday September 30 before class.  Be sure you submit the project on time.  There is a significant grade penalty for late submissions.  (See the syllabus for details.)

  • The project must be submitted as a Word document attached to an email.  Send the email to me (weinberg@temple.edu) and Ashneet (tua91493@temple.edu)
  • Be sure you print and retain a copy of the sent email in the sent items folder of your email system.  This is your proof of on-time submission. 
  • Also be sure to include your name and the project title on the subject line of the email and in the attached document.  The project may not be graded if this information is missing.

Printer Ink and Chateau Lafitte Rothschild

The cost of a gallon of HP printer ink is $8000 making it more expensive than a first growth Bordeaux wine! A gallon of Chateau Lafite Rothschild costs about $2000 to $4000 depending on the vintage. The article states that HP’s profit margin on supplies is 14-16%. If this is correct, some of the cost is certainly related to the cost of producing the ink. I suspect some of the cost is also related to the cost of producing disposable cartridges (which contain the nozzles for the ink), and the allocated cost selling subsidized printers.


The second article discusses Kodak’s printer strategy vs HP’s. Kodak seems to be moving to a model where they charge more for the printer but less for the ink — reducing the cost for each printed page.
