Title
Analysis Of Spatial Information Service Composition Network Based On Ricci Curvature
Abstract
In order to improve the efficiency of spatial information service composition and enhance its stability, this paper proposes to introduce the spatial information service combination network into the geometric space and use Ricci curvature to study the local structure of spatial information service chain and explore the way of connecting to the spatial information service network, and analyse the Ricci curvature and its distribution and excavate the network structure and analyse its meaning. It is found that negative curvature nodes are more heavily loaded and have more service invocations. They are prefer to be distributed over the edge of the graph structure composed of spatial information service chains, and more inclined to the intersection of local structures of the network, the positive curvature on the contrary. And the proportion of negative curvature of this service network is large, which indicates that there is strong connectivity and recall between these different service chains.
