| Abstract: | Purpose/significance] The research aims to propose a collaborative recommendation method for boolean resource in mobile learning platform.Method/process] Firstly, the nearest neighbor set of the target users is determined based on FRUTAI algorithm. Secondly, after filling the user data, a collaborative recommendation method for Boolean resource is put forward. Thirdly, the result of the recommendation according to relevant methods is assessed.Result/conclusion] Empirical results suggest that the recommendation method proposed has a good result by using of Douban as the data set. The improved collaborative recommendation algorithm can be effectively applied to boolean resources in mobile learning platform, and has a perfect effect on recommendation. |
