The ActiveMQ is used to acquire a large amount of the user data, taking advantage of the naive Bayesian algorithm provided by Spark-based MLlib to clean the user data, and using the PageRank algorithm provided by Spark-based GraphX and the Z-Score algorithm provided by MLlib to calculate the user ranking. In the prototype system, the LPA algorithm is finally used and optimized, to group the users of similar features and close ties into the same community quickly, as a foundation for further analysis and utilization of the community user data., correspAuthors=null, authorNote=null, correspAuthorsNote=10.3981/j.issn.1000-7857.2018.23.012, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=NxFDVfac2pGAQLXTSHWAog==, pdfFileSize=1127576, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
