Comparison of algorithm models.

Research proponent	Specific algorithm used
The user profile proposed by researchers such as Billsus D is a hybrid model (composed of users’ long-term preferences and short-term preferences)	KNN algorithm (short-term preference), Naive Bayesian algorithm (long-term preference)
Zeng and other scholars proposed to build user portraits	Vector space model algorithm, Rocchio feedback algorithm, TF-IDF algorithm, and so on
