This paper has three primary research contributions:
- Analysis of the item-based prediction algorithms and identification of different ways to implement its subtasks.
- Formulation of a precomputed model of item similarity to increase the online scalability of item-based recommendations.
- An experimental comparison of the quality of several different item-based algorithms to the classic user-based (nearest neighbor) algorithms.
