Abstract  

[Objective] Introduce the theory of social network analysis to solve the problem in implicit knowledge push service. [Context] The research is carried out by selecting the knowledge preference of logined users within 24 hours based on the digital library environment. [Methods] "N-cliques " and "centrality degree" are introduced to analyze the target users. Make the similar users' implicit knowledge requirement explicit and push knowledge to target users. [Results] The breadth and accuracy of implicit knowledge pushing performance is directly affected by parameter of "n", and the implicit knowledge pushed is of more granularity when the threshold is set to "2". [Conclusions] Our research solved the issue of extreme scarcity of pushing data and poor performance of users' implicit knowledge acquirement, promoting the share of implicit knowledge.
Key words： Social network analysis      Knowledge push service      N-cliques      Implicit knowledge co-occurrence
