introduction

• Focus on relation between course categories and
  students preferences
• Preference Mandatory courses should not be taken
  into consideration when analyzing students
  preference
• Category Classify coursesgtgtEach course covers
  more than one categorygtgtweigh courses
• Fuzzy AI(90),Research(85),Math(70)
• Neural Networks AI(90),Research(85),Math(70)
• Ken Fuzzy and Neural Networks
• Objective construct a web-based course
  recommendation system that only depends on the
  courses chosen by students

4
Prediction methodology

• Datamining technique
• Apriori algorism (Agrawal Srikant, 1994)

5
Recommendation process
Classifying courses/designing weights
Collecting Students Course Selection Records
Make Suggestions to Student
6
Results and Evaluation

• 4 consecutive terms, senior college students
• Class 2001 127 students course selection
  record, 34/83 questionnaires response
• Class 2002 102, 100 response rate
• 6 categories research, theory, math, hardware,
  software, network (information science)

7
Accuracy rate for preference sequence

• General assumption 4th term should have the
  highest accuracy rate
• Explanation fewer prerequisites, more electives,
  tend to follow graduate school guidance
• Class 2002 target 13 students who plan to go to
  graduate school straight after college

8
Proposed Future Research

• Students needs change analysis
• How to find course categories classified by
  students? What are the relations among courses in
  students mind?
• Time series analysis
• Is it possible to develop or plan a series of
  courses depends on the students major interests?
