Embodiment Construction
[0072] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0073] It should be noted that the terms "first" and "second" in the description and claims of the present invention are used to distinguish similar objects, but not necessarily used to describe a specific order or sequence.
[0074] In real life, most complex systems (such as social systems, biological systems, information systems, economic and financial network systems, power and transportation systems, infectious disease transmission systems, etc.) can be abstracted into network structures, and network theory can be used to Quantitatively describe and solve problems on these systems. Sometimes we care about important objects in the research system. For example, in the spread of infectious diseases, users hope to find out which individuals have extensive contacts and try to isolate them. T...

The invention discloses a method and a device for constructing a network evaluation model. The method comprises the following steps: obtaining the weight W of a connected edge between network nodes, and calculating the values of preset indexes for evaluating the importance of the network nodes, wherein the preset indexes comprise the strength and local irreplaceability of the nodes; and accordingto the values of the preset indexes, constructing an elastic potential energy model H corresponding to the network. By utilizing the embodiment of the invention, the network evaluation model capable of reflecting the importance difference of the network nodes can be constructed, the problem that the importance sorting and classification result of the network nodes is poor is solved, and the defects in the prior art are overcome.
Description
technical field [0001] The invention belongs to the technical field of node sorting in complex networks, in particular to a method and device for constructing a network evaluation model. Background technique [0002] In real life, many things exist in the form of systems, such as ecosystems, power systems, transportation systems, public health systems, etc., and these systems can usually be abstracted into networks for processing, for example: in the ecosystem The food chain can be abstracted as a network of predation relationships between organisms, and the transportation system can be abstracted as a network of traffic connectivity between urban nodes, etc. In recent years, complex networks have been continuously concerned by scholars, especially many complex networks in real life present different characteristics from previous network theories, such as: scale-free characteristics, hierarchical characteristics, small-world effects, etc. By studying the network, the charac...
