The invention discloses a method for identifying microblog key users based on an improved
Page Rank. The method comprises the steps that microblog
information data are input, wherein the microblog
information data comprise n microblogs; word segmentation is conducted on texts of the n microblogs; according to a word segmentation result, a
reverse index structure is established, so that retrieval is conveniently conducted according to appointed keywords; according to the retrieved relevant microblog, forwarding hierarchy information of the microblog is extracted and
a weighting directed graph is established, wherein the weighting
directed graph is a forwarding network G; the forwarding network G is divided into a plurality of maximum connected subgraphs Gi; the
Page rank algorithm is applied to each sub network Gi according to the parallelization computing technology; computing results of the sub networks are combined, so that
ranking results of the whole network G are generated; the first m
ranking results of the
ranking results are selected, serve as the key users and are output. According to the method for identifying the microblog key users based on the improved
Page Rank, the parallelization computing technology is adopted, a dynamic forwarding network of a microblog platform is ranked and computed in a
big data environment, so that the key users in the
information transmission process are identified, and the method is applied to the fields of network public
opinion analysis and the like.
