Method for processing information and server

摘要

A method for processing information applied in a server and the corresponding server is described. The method is applied in a server that stores a file set including a plurality of stream media files. The method includes obtaining a transition parameter when a first terminal apparatus accesses a file set when the first terminal apparatus accesses stream media file in the file set; making statistics of transition probability of each stream media file in the file set transiting to the respective stream media files in the file set according to the transition parameter of at least one first terminal apparatus; determining a target stream media file that the first terminal apparatus accesses most frequently in the stream media files in the file set according to the transition probability; and transmitting the target stream media file to a second terminal apparatus.

1. A method for processing information applied in a server which stores a file set including a plurality of stream media files therein, the method comprises:
obtaining a transition parameter at the time of a first terminal apparatus accessing the file set when the first terminal apparatus accesses a stream media file in the file set, wherein, the transition parameter indicates that the first terminal apparatus transits to a second stream media file from a first stream media file in the file set when the first terminal apparatus accesses, and the first stream media file is the same as or different from a second stream media file; making statistics of a transition probability of each stream media file in the file set transiting to the respective stream media files in the file set according to the transition parameter of at least one first terminal apparatus; determining a target stream media file that the first terminal apparatus accesses most frequently in the stream media files in the file set according to the transition probability; generating a Markov chain related to the stream media file in the file set; generating file nodes in the Markov chain corresponding to the stream media files in the file set one by one; generating a start node of the Markov chain positioned at front of all the file nodes and an end node of the Markov chain positioned at the end of all the file nodes; generating a Markov state transition matrix related to the Markov chain according to the transition probability; determining nodes having a two-way intercommunication characteristic in the Markov chain according to the Markov state transition matrix, wherein, the transition probability from a first node of any two nodes having the two-way intercommunication characteristic to a second node of any two nodes having the two-way intercommunication characteristic being lamer than zero and the transition probability from the second node of any two nodes having the two-way intercommunication characteristic to the first node of any two nodes having the two-way intercommunication characteristic being lamer than zero; wherein, determining the stream media file having the characteristic of frequent returning in the stream media file in the file set as the target stream media file according to the transition probability includes:
determining the node having the characteristic of frequent returning in the Markov chain according to the transition probability;determining other nodes having the two-way intercommunication characteristic with the node as having the characteristic of frequent returning when the node in the Markov chain is determined as having the characteristic of frequent returning; andusing the media file corresponding to the node having the characteristic of frequent returning as the target stream media file; transmitting the target stream media file to a second terminal apparatus.
