  4. 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

Web Services Manipulating the Ontology • addTreeNode(subRoot, name); • removeTreeNode(nodeName); • addTreeLeave(subRoot, name); • removeTreeLeave(leaveName); • selectLeave(leaveName); • takeTest(testName); • gradeTest(testName, grade); • enterGrade(roster, testName, grade); • sort(roster); • display(roster, range); • login(userName, pwd); • logout();

  7. Application Building • testPaper(subRoot, name); • login(userName, pwd); • selectLeave(name1) … selectLeave(namen); • buildTest(testName); • logout(); • testGiving(testName); • login(userName, pwd); • takeTest(testName); • gradeTest(testName, grade); • enterGrade(roster, testName, grade); • logout(); • reportGrade(roster, key1, key2, key3); • login(userName, pwd); • sort(roster); • display(roster, range); • logout();
