Hierarchical Intra-Context Handoff Awareness Approach to Personal Recommender Systems: A mobile DTV case study

This paper proposes a hierarchical intra-context handoff awareness (HICHA) approach to personal mobile TV recommender systems. The HICHA approach involves a basic hierarchical approach that extends your features to context-aware and intra-context handoff awareness approach. The user model, prediction model and calculate of users interest methods are presented. Moreover, experiments and results using HICHA approach are completed, showing its effectiveness.
