The invention discloses a data network relationship processing method and device. The method comprises the following steps that: an obtaining step: obtaining a data network relationship, wherein the data network relationship is used for indicating an information transferring relationship among a plurality of objects; a determining step: according to the information transferring relationship, determining the corresponding incidence relationship of the objects, wherein the objects comprise a source object and a target object; a combination step: combining the source object or the target object which has the same incidence relationship with the same object into the same temporary network, wherein the temporary network comprises a source object temporary network and a target object temporary network; a reconstruction step: according to the source object temporary network and the target object temporary network, reconstructing the data network relationship; and a judgment step: under a situation that the data network relationship does not have the source object or the target object, returning to the obtaining step, and otherwise, terminating data network relationship processing. By use of the method, the technical problem that the data network relationship of mass objects can not be processed under the environment of big data is solved.
