Provided are a method, a device and a 
system for calculating network video real-time attention. The method includes: step 1, setting statistic 
granularity of network video playing time; step 2, obtaining network video playing data needing statistic 
processing according to the set statistic 
granularity of the network video playing time; step 3, calculating the playing time of each network video in the statistic 
granularity; step 4, calculating the playing attention of each network video in the category according to the playing time of each network video; and step 5, counting up the playing time of each network video playing time and category information of the network video playing attention of each network video, using the sum as the real-time playing time of each network video in a 
specific time period, and obtaining the real-time attention of each network video according to the playing time. The method, the device and the 
system for calculating network video real-time attention increase 
reaction speed of network videos high in attention of a network searching engine, timely provide video 
hot topics for users and enable a search 
server to response to hot events as soon as possible.
