Abstract

The invention provides application of a dense subgraph mining technical framework in a graph database. The application of the dense sub-graph mining technical framework in the graph database comprises the following steps: S1, in webpage hyperlink topological graph analysis, on the basis of an existing D-core decomposition algorithm, a D-frame is constructed tree by tree and layer by layer by means of the hierarchical structure property of D-core, and the method is divided into a Top-down method and a Bottom method; according to the application of the dense subgraph mining technical framework in the graph database, topological information of vertexes on the directed graph and specific properties of the directed graph are fully mined, the time for querying a strong correlation webpage set is reduced by at least one order of magnitude in combination with an existing graph calculation method, and meanwhile, the indexes kmax and skyline-area provided by the method are proved to have a relatively strong positive correlation relationship with the degree of participation of the webpage.

Description

technical field [0001] The invention relates to the field of graph databases, in particular to the application of a dense subgraph mining technical framework in graph databases. Background technique [0002] With the development of computer hardware and the increase of the total amount of data, data mining algorithms have been applied in many fields, and a considerable part of these huge and complex data, such as web page hyperlink topological graphs, can be naturally analyzed in the form of graphs. Presented, these graphs often show a basic structure similar to the community. The community is a dense subgraph composed of closely connected nodes. D-core is a manifestation of the community on the directed graph. It has been widely used in fields such as community search, role recognition, and spam detection. [0003] D-core is a dense subgraph model proposed in recent network research, although there are many existing dense subgraph models such as k-core, k-truss, and k-cliq...
