Cheese Selection
wichCheese: The Cheese Expert system. This system returns the name and details of a cheese to drink with a meal.
The system tries to classify cheese based on the criteria that the developers (the Experts in this scenario) selected in order to guide the user towards identifying a particular cheese.
The classification types that were chosen are as follows:
Cheese Type Texture Colour Flavour Aroma Common food pairings
These areas were selected as cheese classification is not a field that experts agree on but these characteristics are the ones most commonly reference. It was determined that these characteristics would yield the best results for identification. In addition to these characteristics, the country of origin and the milk source were included in order to provide additional information to the user upon identification. There are 30 varieties of cheese included in th system. They are as follows:
Gouda Cheddar Brie Parmesan Mozzarella Feta Asiago Mascarpone Muenster Montery Jack Ricotta Cottage Cheese Gorgonzola Cream Cheese Danish Blue Jarlsberg Provolone Cantal Roquefort Fromage Blanc Stilton Explorateur Reblochon Castigliano Caciotta al Tartufo Innes Button Brunost Sapsago Calcagno Manchego
The system uses Forward Chaining to derive the results. The user is prompted with a series of questions for each characteristic to determine the cheese in question. On system start the facts are loaded into the system, this becomes the Knowledge Base. As the questions supplied by the system are answered, facts that do not meet the characteristic are removed from the Knowledge Base. This is repeated until a solution is found. Upon identification of a solution the user is given the full details of the cheese in question (the fact of the cheese). If no solution is found the user is notified of this and the process is terminated.
To use the Expert System, you will need at least CLIPS version 6.3. Use the navigation window to load the file "wichCheese.clp" Upon loading the file type the command " (reset) " with the brackets or hit "ctrl + E" followed by " (run) " or "ctrl + R". Answer the questions while keeping the accepted responses in mind. These accepted responses are displayed alongside each question. In order to reuse the system simply reset and run once again.
Data on the cheese varieties in the system was pulled from www.cheese.com and http://chefsblade.monster.com/training/articles/980-how-to-classify-cheese?page=1.
