Method for predicting author cooperation relation in academic heterogeneous information network

InactiveCN106778894AEfficient understandingEfficient scientific research cooperationCharacter and pattern recognitionCharacteristic spaceTime dynamics
The invention discloses a method for predicting an author cooperation relation in an academic heterogeneous information network. The problem about author cooperation relation prediction is solved by utilizing a heterogeneous information network close to a real world. The method comprises the following steps: acquiring the topological attribute of the network according to different measurement of a metapath in the constructed academic heterogeneous information network, introducing concepts of temporal dynamics, transfer similarity and author attribute to acquire the content information of the network, combining the topological attribute and the content information to acquire a characteristic space based on the metapath and the content information, and finding the optimum weight of each characteristic attribute according to the obtained characteristic attribute set and by a logical regression algorithm to predict the author cooperation relation. According to the method, the potential cooperation relation of scholars can be excavated by utilizing academic big data, the scholars can be helped to perform efficient scientific research cooperation and know the academic circle of the scholars, and in particular a good prediction effect on high-yield scholars and high-frequency cooperation relation is achieved.
