Application of C4.5 Algorithm in Web-Based Learning Assessment System

The paper constructs an Online Learning Behavior Assessment System based on data mining technique. The process of constructing "online learning behavior - effect" model with C4.5 algorithm is described and is put into practice for grading the students' online learning behavior. The experimental results show that over 90% teachers and students are satisfied with the assessment results. The application of the system provides an objective, reasonable method for assessing online learning.
