Abstract

PURPOSE:To recognize the depth of relations between nodes at sight by graphically displaying degrees of relations of a noticed node to the other nodes by size relations of nodes to make them conspicuous. CONSTITUTION:A network structure is stored in a network structure information storage device 1, and the noticed node is selected by a node selecting device 2. Degrees of relations of the noticed node to the other nodes are calculated by an inter-node relation degree calculating device 3, and the network structure is displayed on a display device 4. That is, the noticed node is selected from the normal network structure display with an arbitrary device by the node selecting device 2. Degrees of relations of the node to the other nodes are calculated by the inter-code relation degree calculating device 3, and the network structure where scales of nodes are changed is displayed on the display device. When another node should be notice, it is selected with the arbitrary device by the node selecting device 2 in the same manner. This operation is repeated till selection of END.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for data having a network structure.

0002

[Prior Art] Fig. 2 shows the US Hewlett
This is a network structure display device used in Packard's Teamwork. The network structure consists of nodes (represented by circles or rectangles) and connecting lines (represented by straight lines or curved lines) representing the relationships between the nodes.

0003

[Problems to be Solved by the Invention] In conventional network structure display devices, a plurality of nodes are displayed in the same size. For this reason, when the network structure is complex with a large number of nodes and connecting lines, there is a problem in that it is difficult to see at a glance the depth of the relationship between each node.

The present invention has been made to solve this problem, and it shows the degree of connectivity between a node of interest and nodes that are deeply related to each other by the size of a displayed figure, and also shows the degree of connectivity between a node of interest and nodes that are deeply related to each other. The purpose is to display the connection information between the nodes without losing the connection information.

[0005]

[Means for Solving the Problems] A network structure display device according to the present invention includes a network structure information storage device for storing network structure information;
The present invention includes a clause selection device for selecting a clause of interest, an interclause degree calculation device for calculating the degree of association between the clause of interest and other clauses, and a display device for displaying a network structure.

[0006]

[Operation] In the network structure display device according to the present invention, as the number of connections between the node of interest and other nodes increases,
Display sections smaller. That is, the greater the degree of relevance, the larger the node is displayed, and the smaller the degree of relevance, the smaller the node is displayed. In this way, the degree of association between the clause of interest and other clauses is illustrated and highlighted by the size relationship of the clauses.

【Example】

Example 1. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a network structure display device according to the present invention. A network structure information storage device 1 stores the network structure. 2 is a clause selection device that selects a clause of interest. 3 is an interclause relevance calculation device that calculates the relevance of the node of interest to other clauses. 4 is a display device that displays the network structure.

The operation of the embodiment of the present invention will be explained with reference to FIG. From the normal network structure display, a node of interest is selected by an arbitrary device using the node selection device 2. Next, the degree of association between this node and other nodes is calculated by the internodal relationship calculating device 3, and the network structure with the scale of the nodes changed is displayed on the display device 4. When paying attention to other clauses, the clause of interest is similarly selected by the clause selection device 2 using an arbitrary device. Repeat this until you select END.

Next, details of one embodiment of the present invention will be explained with reference to FIGS. 4 and 5. As shown in FIG. 4, it is assumed that there are nine nodes from n11 to n33. The node we are currently focusing on is n22 in the middle. If n22 is the parent, the children are {n11, n12, n23, n32}. In the case of grandchildren, it is {n21, n31, n33}. However, n
23, n32, which can be both a child and a grandchild from the parent's point of view, choose the one that is closest to the parent and make it the child. Therefore, when focusing on n22, there are the following three sets of nodes connected to n22, including grandchildren. This is expressed as follows. S0={n22}...Parent itself
S1={n11, n12, n23, n32}...Set of children S2={n21, n31, n33}
...Grandchildren's gathering

Next, the degree of association between the parent node and each set is defined as follows. Since S0 is the parent node itself, the distance from the parent node is 0. S1 is considered to be one distance away from the parent. S2 is 2 away from the parent. Similarly, consider that the set of Sm is m away from the parent. In this example, the attenuation function is y=an (0<a<1
, 0<n<5). n is the degree of association, and y indicates the scale of the clauses belonging to the set of clauses with that degree of association. Substituting the degree of association of each set of clauses into n, we get the following. If a=1/2 is substituted, when the scale of S0 is 1, the scale of S1 will be 1/2, and the scale of S2 will be 1/4. In Example 1 shown in FIG. 5, nodes where n is 2 or more have a constant scale.

Example 2. As an application of the present invention, the following attenuation function y=an (0<a<1, n=0,1)y=0(n>1
), only the parent clause and direct child clauses can be displayed, as shown in Figure 6. In this way, the attenuation function can be made not to be displayed when the degree of association exceeds a certain value.

Example 3. As another example, a tree structure is a special case of a network structure, and the degree of association between nodes can be defined in the same way, so the present invention can also be applied to a tree structure as shown in FIG.

[0013]

[Effects of the Invention] According to the present invention as described above, even when the network structure has a large number of nodes and connecting lines and is complex, the scale of the nodes can be changed to determine the degree of association between the node of interest and other nodes. This allows you to understand it visually. Furthermore, the display can be controlled based on the degree of association between the target clause and related clauses. It can also be used similarly for tree structures. Further, when it is desired to reduce the display area of the network structure in terms of screen efficiency, there is also an application in which arbitrary screen compression processing is performed after determining the scale of nodes according to the present invention.
