摘要

The diversity and volume of textual data in the course reviews area are overwhelming. These data offer faculties with a chance to capture topic interests of learners and further make relevant recommendations for them. "Like" or "+1" considered as a specific interactive means among learners has been commonly applied to enriching the interactivity and flexibility of online community. This information can reflect their supporting, appreciation for the textual contents and topical interests. In view of this situation, the topic model by incorporating the behavioral feature "like", namely Like-Latent Dirichlet Allocation (Like-LDA), is proposed to detect the latent topic interests in course reviews. The experimental results on the real-life dataset show that, Like-LDA can gain better performance in extracting the new hidden topics, higher accuracy of topic detection and words coherency in each topic than LDA.
