System Features
The project will create a Web Services-based
application Teaching Assistance, which allows

• Service providers to register new Web services
• Instructors to test questions and solutions into
  an ontology to form a semantic Web
• Instructors to build test papers based on the
  existing Web services
• Give a test online and have the test
  automatically graded
