The comparison algorithms.

Number	Algorithm	Theory	Operation principle
1	Literature [24]	Matrix decomposition	The rating matrix is used as input, the inner product of the low-rank matrix of users and items is used to represent the rating, and the objective function is minimized by the alternate least squares (ALS) technique
2	Literature [25]	Probability matrix decomposition	Only score data is used for collaborative filtering, and Gaussian distribution is introduced to model the underlying factors of users and items
3	Literature [26]	Parallel neural network	An additional sharing layer on top of the two neural networks connects the two parallel networks so that the learned user and project potential factors can interactively predict ratings. This model proves that the sparsity problem can be effectively alleviated by using comment text
