Abstract: In microblog platform,users’ messages arrive the system in a temporally ordered sequence,and efficient management of microblog streaming data can handle users’ queries timely.Based on provenance of database,a provenance based information management method for microblog messages was proposed.Firstly,the provenance is defined as messages about a common event according to the generation,development and changing of an event.Secondly,the message streaming is divided into different provenances and they are maintained dynamically when a new message comes.Finally,the messages of provenance are used to answer user’s queries.The experiments show that the proposed method is efficient in memory usage and time cost,and can be used to timely response of users’ queries.
