Abstract

The embodiment of the invention provides a batch mining method and device for the total exposure of social media information, and the method comprises the steps: traversing N pieces of to-be-mined social media information according to a preset period, and generating N pieces of line data L; traversing all the N pieces of row data L once according to a pre-constructed counter group C based on a keyvalue pair data structure to obtain counter groups C' corresponding to the N pieces of row data L; and recursively determining the total exposure of each piece of social media information corresponding to each counter according to the exposure frequency pv of each piece of social media information and the forwarding list rlist of the piece of social media information. After the batch mining process of the total exposure of the social media information is used, the current total exposure can be quickly calculated, and the total exposure of all information in the period of time can be found outonly by traversing the data once by the algorithm and is quick and accurate enough.

Description

technical field

[0001] The invention relates to the fields of data analysis and data mining, in particular to a method and device for batch mining total exposure of social media information. Background technique

[0002] Users on social media can send messages, repost other people’s messages, give likes and comments to any message, etc. In modern social media, the total exposure of each piece of information is very important data, which can be used as an important basis for search ranking. But its calculation is more difficult, because first of all it is a real-time growing number, and as the forwarding chain becomes longer and longer, more and more places need to be calculated.

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: for some situations where multi-stage forwarding is generated, the total exposure may be much different from the first-order exposure, and now a method is ...
