[Bcakgroud] With the enrichment of network platform types, users are no longer limited to using single platform to obtain knowledge but tend to expand the channels of content acquisition, generating and sharing content among multiple platforms. Therefore, it is of great significance to focus cross-platform users to try to explore their knowledge exchange behavioral patterns and user classification to understand cross-platform knowledge exchange behaviors and reveal cross-platform behavioral systems.[Methods] In this paper, we take 120 users in Bilibili knowledge board as the research object, and on the basis of user alignment, we obtain their attributes, contents, and interaction data on Bilibili and Weibo, construct cross-platform user classification model, and utilize the K-means algorithm to realize cross-platform user classification and its behavioral analysis.[Results] Cross-platform users have three types: Cross-platform bilaterally heterogeneous users, Cross-platform bilaterally homogeneous users, and Cross-platform unilaterally active users. Cross-platform bilaterally heterogeneous users account for the largest proportion, they will present different contents on the platforms based on their perception of the platforms; Cross-platform bilaterally homogeneous users present similar contents on the two platforms, but there is a large difference in the degree of interaction between the two platforms; Cross-platform unilaterally active users account for the smallest proportion, they only active on one platform, the degree of input and interaction are significantly higher than the other platform. [Innovation] This paper constructs a cross-platform user classification model, reveals the cross-platform bilaterally develop strategy as the mainstream for cross-platform users, and raises suggestions for knowledge exchange services based on user classification.
