摘要

With the rapid development of the Internet, the exponential growth of information resources makes it harder for users to retrieve information that is useful to themselves. But the advent of personalized recommendation systems has brought the hope and help to users. This paper introduces the background and meaning of the original Slope One static algorithm and the current researches. It thoroughly explores the improvement of Slope One algorithm at home and abroad, and clarifies the advantages and disadvantages of the algorithm. Based on the original Slope One static algorithm, an incremental Slope One algorithm is proposed. The advantage of incremental algorithm is that it can adapt to the instantaneous changes of data. Combined with the easy implementation, easy expansion and high accuracy of Slope One, Slope One incremental algorithm has good practicability.
