Example Embodiment
[0051] Example 1
[0052] The embodiment of the present invention provides a graphical expression method for a compact hierarchical data structure, see Figure 4 , the method includes the following steps:
[0053] 101: Each data set constructs a corresponding tree data structure according to the internal hierarchical relationship;
[0054]102: Each node corresponds to a node block in the graphical representation, and each node block has key attributes of level, height, length, starting position, color, shading, simple text information and detailed text information;
[0055] Through the above settings, the user can quickly locate the position of each node in the tree structure and obtain some key information of the node. During the specific implementation, other key attributes can also be included, which can be set according to the needs of practical applications. The present invention The embodiment does not limit this.
[0056] 103: Quickly judge the importance of the node...

[0061] Example 2
[0062] The scheme in Embodiment 1 is further introduced below in conjunction with specific calculation formulas and accompanying drawings, and is described in detail below:
[0063] For convenience, with figure 1 The tree structure in the example is described as an example, and the graphical expression method proposed by the embodiment of the present invention is called a block tree. Figure 5 given in figure 1 The block tree representation corresponding to the tree structure given in . The block tree can be placed in the manners of "from left to right", "from right to left", "from top to bottom", and "from bottom to top" as needed (during specific implementation, this embodiment of the present invention does not do this. limit). The following is a detailed description of its production method in a "top-to-bottom" manner.
[0064] 201: Construct a corresponding tree data structure for the data set according to the internal hierarchical relationship;

[0105] Example 3
[0106] Below in conjunction with two examples, accompanying drawing, feasibility verification is carried out to the scheme in embodiment 1 and 2, see below for details:
[0107] 1. Use block tree to realize the visual expression of discussion post data:
[0108] In the information society, in many cases, different people will participate in the discussion of the same issue. For example: every discussion thread in the forum. Discussion threads are usually initiated by one person who proposes a topic to be discussed. In the future, different people will reply to this topic according to their own interests.
[0109] Figure 8 Just a simple discussion thread structure. exist Figure 8 , the text in the text box is the opinion expressed by the user. The letters in the first gray box at the back indicate the user who posted the comment, and the numbers in the second gray box indicate the order in which these comments were published. In this example, User A i...
