Hierarchical Intra-Context Handoff Awareness Approach to Personal Recommender Systems: A Mobile DTV Case Study

摘要

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.
