A Web Based Recommendation System for Personal Learning Environments Using Hybrid Collaborative Filtering Approach

3 . ABSTRACT: The large growth of Web has influenced the generation of huge e-learning resources. This work is focused to devise a personal recommendation system that will address the sparsity and cold-start problems and that will provide a have a more diverse recommendation list for each learner. Here Improved Neighborhood- based Collaborative filtering and Hybrid Genetic algorithm with Particle Swarm Optimization (PSO) method is implemented. These techniques are employed for improving the diversity, and the convergence towards the preferred solution taking into account the preferences of users. The results obtained from the experiments show that the proposed method outperforms current algorithms in terms of accuracy measures and can alleviate cold-start and sparsity problems and generate a more diverse recommendation list as well.
