| Abstract: | To deal with data sparseness problems in the traditional collaborative filtering algorithm, a new recommendation algorithm of valuation filling based on concept hierarchy was proposed through improving the traditional collaborative filtering algorithm. Simulation experiments of the new recommendation algorithm were conducted. The results indicate that the proposed algorithm has favourable recommendation effect in sparse data sets and can improve the quality of recommendations. |
