Embodiment 1

[0027] Such as figure 1 Shown is a flow chart of a method for comparing hierarchical structure data through barcodes provided by an embodiment of the present invention, and the method includes:

[0028] Step S101, traversing at least two hierarchical structure data to be compared by using a depth-first traversal method DFS, and obtaining a node sequence of the hierarchical structure data to be compared.

[0029] In the embodiment of the present invention, the corresponding node sequence can be obtained through the traversal method of DFS (Depth First Search, depth-first traversal) for hierarchical structure data. Wherein, each node in the node sequence includes its corresponding node parameter, and the node parameter includes but not limited to: index value, level, internal attribute and so on.

[0030] The step of obtaining the node sequence of the hierarchical structure data through DFS traversal belongs to the prior art, and will not be repeated here.

Embodiment 2

[0076] Such as Figure 9 Shown is a structural diagram of a system for comparing hierarchical data through barcodes provided by an embodiment of the present invention, and the system includes:

[0077] The node sequence obtaining unit 901 is configured to traverse at least two hierarchical structure data to be compared through DFS, and obtain a node sequence of the hierarchical structure data to be compared.

[0078] In the embodiment of the present invention, the corresponding node sequence can be obtained by traversing the hierarchical structure data through DFS (Depth First Search, depth-first traversal). Wherein, each node in the node sequence includes its corresponding node parameter, and the node parameter includes but not limited to: index value, level, internal attribute and so on.

[0079] The step of obtaining the node sequence of the hierarchical structure data through DFS traversal belongs to the prior art, and will not be repeated here.

Abstract

The present invention is applicable to the field of visualization and visual analysis, and provides a method and system for comparing hierarchical structure data based on the visual form of a barcode tree. Perform traversal to obtain the node sequence of the hierarchical structure data to be compared; convert the nodes in the node sequence into corresponding bar-shaped visual elements according to the preset conversion conditions, and arrange the bars in sequence to obtain a barcode tree; align The at least two barcode trees are compared, and the barcode trees are sorted according to a preset sort order. By implementing the embodiment of the present invention, it is possible to conveniently and intuitively establish a corresponding relationship between multiple hierarchical structure data through the barcode tree, and improve the comparison efficiency between the hierarchical structure data.

Description

technical field [0001] The invention belongs to the field of visualization and visualization analysis, in particular to a method and system for comparing hierarchical structure data based on the visualization form of a barcode tree. Background technique [0002] Hierarchical data is a kind of data that people often encounter in daily life, such as classified data of library bibliography, file directory of computer disk, organizational structure of company, etc. For hierarchical data, there are many different types of visualizations to help users understand exploration, such as node-connection tree, tree diagram and other visualization methods. An important perspective in the analysis process is to compare multiple levels of data to gain insights into the internal laws of the data. However, it is difficult for existing technologies to assist users in establishing multiple levels by adding connections or interactive highlights between the same nodes. The corresponding relatio...
