Academic networks in the real world can usually be portrayed as heterogeneous
information networks (HINs) with multi-type, universally connected nodes and
multi-relationships. Some existing studies for the representation learning of
homogeneous information networks cannot be applicable to heterogeneous
information networks because of the lack of ability to issue heterogeneity. At
the same time, data has become a factor of production, playing an increasingly
important role. Due to the closeness and blocking of businesses among different
enterprises, there is a serious phenomenon of data islands. To solve the above
challenges, aiming at the data information of scientific research teams closely
related to science and technology, we proposed an academic heterogeneous
information network embedding representation learning method based on federated
learning (FedAHE), which utilizes node attention and meta path attention
mechanism to learn low-dimensional, dense and real-valued vector
representations while preserving the rich topological information and
meta-path-based semantic information of nodes in network. Moreover, we combined
federated learning with the representation learning of HINs composed of
scientific research teams and put forward a federal training mechanism based on
dynamic weighted aggregation of parameters (FedDWA) to optimize the node
embeddings of HINs. Through sufficient experiments, the efficiency, accuracy
and feasibility of our proposed framework are demonstrated
