Expert Systems Lab

A Java application for demonstrating the use of ontologies to represent and reason with knowledge in Expert Systems. This particular system allows users to build (virtual) pizzas and then infers interesting properties about them. It also provides explanations (justifications) for why it makes these inferences.

For Users: Installing and using the system

Requirements:

• Java Runtime Environment 1.8+

Steps:

1. Use git to clone this repository or download the zip archive.

2. If you cloned the repository, change into the expertsystemslab-master/ directory. If you downloaded the zip archive, extract it and change into the expertsystemslab-master/ directory.

3. Double-click the pizzaexpert-${version}.jar file. Alternatively, open a terminal or command prompt, change into the expertsystemslab-master/ directory, and run java -jar pizzaexpert-${version}.jar.

Note: pizzaexpert-${version}.jar requires the following directory structure to launch correctly:

pizzaexpert-${version}.jar
