Abstract

This paper studied the problem that the Slope One recommendation algorithm was not accurate enough when the data sparseness was high. Combining the idea of association rules with the method of weighted analysis, it proposed the Slope One algorithm based on association rule strategy weighting to improve the algorithm from two aspects: user score and project feature. The experiment used the FilmTrust dataset, which contained 35 497 rating for 2 071 movies by 1 508 users. After many experiments and analysis, the proposed method achieves the expected optimization effect, and also provides a research basis for the further diversification and improvement of subsequent algorithms.
