Description

  The present invention relates to an information display program and an information display method for displaying nodes of a target hierarchy among hierarchically classified tree structure data.

  Conventionally, in data storage or the like, a hierarchical data structure is used. As a technique for processing this tree-structured data, for example, Japanese Patent Application Laid-Open No. 9-305363 discloses the end of classification while grasping the entire data structure when inputting data in a hierarchically classified data structure. The data is displayed in a tree structure in one area of the window, and the detailed data of the specified node in the tree structure is displayed in the other area of the window. An information display input method is disclosed.

  Japanese Patent Laid-Open No. 2002-140352 discloses that a high-level concept is arranged in the central portion and the surroundings are searched in order to search for information hierarchically for the purpose of correctly searching for information intended by the user. An information search system is disclosed in which a subordinate concept as an option is arranged, a subordinate concept selected there is arranged in the center, and a subordinate concept as a further option is arranged around the subordinate concept.

JP-A-9-305363 JP 2002-140352 A

  However, the technique disclosed in Patent Document 1 is that the problem is to easily input the data of the end node while grasping the configuration of the entire data. If you move the focus from one node to another node and do not close the current focused node hierarchy, the previous focused node hierarchy will remain and be displayed on the screen. As a result, the number of nodes to be processed becomes enormous and the screen display may be difficult to see. In addition, in order to display a target node, it is necessary to click on the screen with a mouse, and there is a problem that an intuitive operation cannot be performed.

  Further, in the technique disclosed in Patent Document 2, it is considered that a certain degree of intuitive operation can be performed from a configuration in which a higher concept is arranged in the central portion and a lower concept as an option is arranged around it. When shifting the focus from a subordinate concept node to another subordinate concept node, it is necessary to perform screen switching work, and the target node cannot be reached on one continuous screen, and thinking about search is interrupted. In addition, there is a problem that it takes time to select a node.

  The present invention has been made in view of the above points, and can focus on a target node by an intuitive operation on one continuous screen, and in particular, when the data hierarchy is deep, the current focus An information display program that eliminates the need for special work to close a node that has been focused until then, and as a result, quickly finds the target node An object is to provide an information display method.

The information display program of the present invention is
An information display program for displaying data in a tree structure including a root that is the highest hierarchy and nodes in a lower hierarchy connected by an edge from the root,
Computer
A node arrangement means for arranging one or more nodes in a lower hierarchy connected by edges so that each node does not overlap radially from a root or a node of an upper hierarchy;
An initial display means for displaying a route or a node of a predetermined upper layer including the route on the screen;
Selection accepting means for focusing a desired route or node by a predetermined operation;
An enlargement ratio changing means for enlarging or reducing the screen displayed by the initial display means to a desired enlargement ratio by a predetermined operation;
Display hierarchy determining means for determining which hierarchy can be displayed according to the enlargement ratio of the screen changed by the enlargement ratio changing means;
Since the screen has been enlarged, the display hierarchy determination unit can display a predetermined lower hierarchy, and the node hierarchy focused by the selection reception unit is higher than the hierarchy that can be displayed by the display hierarchy determination unit. An enlarged display means for displaying a direct node of the hierarchy one level lower than the focused node when
When the focus is moved from the node focused by the selection accepting unit to another node in the same hierarchy or higher hierarchy, one node below the other node among the nodes in the lower hierarchy than the other node Node erasure means for erasing nodes other than direct nodes in the hierarchy from the screen;
When the hierarchy that can be displayed by the display hierarchy determination means is moved up to the hierarchy of the node displayed on the screen by reducing the screen, the display hierarchy determination means can display the hierarchy. A reduced display means for erasing nodes lower in the hierarchy from the screen;
When the node erased by the reduced display means is focused, the focus is set on the direct upper node of the node that was focused before being erased and the lowest hierarchy node that can be displayed by the display hierarchy determining means. A focus moving means for moving;
It is characterized by functioning.

  According to the information display program of the present invention, since the lower layer nodes are arranged radially around the root or upper layer nodes by the node arrangement means, the operator visually observes all the nodes displayed at that time. This makes it easy to select a node. Note that this node arrangement means always functions at all times when a node is displayed on the screen. Further, when the information display program of the present invention is executed by the initial display means, it is possible to determine the hierarchy that is initially displayed on the screen.

  Further, it is possible to focus a desired route or node among the routes or nodes currently displayed by the selection receiving unit. Note that the focus is a state in which the route or node is noticed or selected, and a state in which some input is received or preparation for processing is intended. Further, the node displayed on the screen can be enlarged or reduced to a desired enlargement ratio by the enlargement ratio changing means, and the size can be set as desired by the operator.

  In addition, since the display hierarchy determining means can display up to the hierarchy corresponding to the enlargement ratio of the screen at that time, the lower hierarchy nodes are not opened on the screen that is not sufficiently enlarged, and adjacent nodes and nodes are not displayed. It is possible to prevent squeezing into a narrow area and to make the node easy to see for the operator.

  Further, when the lower hierarchy of the focused node can be displayed by the display hierarchy determining means, the direct display node of the hierarchy one level lower than the focused node is automatically displayed by the enlarged display means. be able to. As a result, it is possible to quickly and continuously view the lower-level nodes of the focused node on one screen, and quickly reach the target node. A direct node means a node that is directly connected from a certain node by an edge.

  Further, when the focus is moved from the node focused by the selection receiving means to another node in the same hierarchy or higher hierarchy, unnecessary lower hierarchy nodes are automatically deleted from the screen by the node deletion means. Therefore, when the focus is moved to another node for searching, a special operation for closing the node that has been displayed so far becomes unnecessary.

  Further, when the hierarchy that can be displayed by the display hierarchy determining means is moved up to the hierarchy of the node displayed on the screen due to the reduction of the screen, it can be displayed by the reduced display means. Since the nodes in the lower hierarchy are closed, it is possible to always display a node having a size that is easy to see on the screen.

  When the lower-level node focused by the reduced display means is closed, the focus is automatically moved to the immediate upper node by the focus moving means. As a result, only by reducing the screen, the work of shifting the focus to the upper hierarchy is automatically performed, and the labor required for the search can be reduced. Note that the direct upper node means a node on a route obtained by repeatedly tracing the direct node directly connected at the edge in the upper layer direction. Further, the order in which the respective means as the respective constituent elements are executed may be changed within a range in which the operation of the information display program of the present invention is not hindered.

A preferred example of the information display program of the present invention is:
Hierarchical display means for displaying all the nodes up to a predetermined hierarchy within the range of the lower hierarchy that can be displayed by the display hierarchy determining means regardless of the hierarchical position of the node focused by the selection accepting means. It is characterized by that.

  According to a preferred example of the information display program of the present invention, a predetermined hierarchy within a range of lower hierarchies that can be displayed by the display hierarchy determination means by the hierarchy display means regardless of the hierarchy position of the focused node. All the nodes up to can be displayed. For this reason, when the screen is enlarged, a lower hierarchy of a certain range can be displayed at a time, and the selection of nodes can be made easier.

A preferred example of the information display program of the present invention is:
Hierarchical related information storage means for storing hierarchical related information for associating nodes having similar meanings for each hierarchy;
Hierarchical related information holding means for holding, by a predetermined operation, the hierarchical related information of a focused node and a direct upper node of the node;
When the focus is moved from the node holding the related information by hierarchy to the root or another node in the upper hierarchy by the selection accepting unit, the root in which the focus is moved or a node in a lower hierarchy than the node The hierarchical related information comparing means for comparing the hierarchical related information with the hierarchical related information held by the hierarchical related information holding means,
Node option display means for displaying, as a candidate for a node to be newly focused, a node having hierarchical related information that is compared by the hierarchical related information comparison means and has a complete match or a partial match.
Is further provided.

  According to a preferred example of the information display program of the present invention, nodes having similar meanings for each hierarchy are associated with each other by the related information storage means for each hierarchy. Nodes with can be associated. Note that a node having a different system means a node that is not related to the above-described direct node and direct upper node as seen from a certain node.

  In addition, the related information holding unit for each hierarchy moves the focus from the focused node to another node in order to hold the related information for each hierarchical level of the focused node and its immediate upper node by a predetermined operation. Even if it makes it, it can hold | maintain the relevant information according to the hierarchy of the node which focused before that.

  In addition, by the related information comparison means by hierarchy, the related information by hierarchy of the node (reference destination node) in the lower hierarchy of the root or node to which the focus has been moved next and the previously focused node (reference source node) are retained. Compared to the related information by hierarchy, whether the node related to the previously focused node is in the next lower-level node of the root or node to which the focus has been moved, and When there is a node to do, it is possible to clarify which node the node is.

  In addition, the node option display means selects a node having hierarchically related information that matches completely or partially matches among the roots or lower-level nodes of the node to which the focus has been moved, that is, the node that has been previously focused. Since related nodes are displayed as candidates for a node to be newly focused, a node having a meaning similar to that of a previously focused node can be easily searched among nodes of different systems.

A preferred example of the information display program of the present invention is:
It is further characterized by further comprising detailed processing means for performing another predetermined process when a predetermined operation is performed on the focused node.

  According to a preferred example of the information display program of the present invention, when a predetermined operation is further performed on the focused node by the detailed processing means, another predetermined process is performed. Another program can be displayed, or another program can be started by causing each node to function as a menu.

A preferred example of the information display program of the present invention is:
The detailed processing means can be executed on all of the focused nodes among the nodes in which the hierarchical related information is held and the nodes displayed by the node option display means.

  According to a preferred example of the information display program of the present invention, in all of the nodes newly focused among the nodes focused before the layer-related information is held and the nodes displayed by the node option display means Since the detailed processing means can be executed, it is possible to display and compare detailed information of a plurality of related nodes in parallel, and to execute processing related to the plurality of nodes in parallel.

A preferred example of the information display method of the present invention is:
An information display method for displaying data using a computer in a tree structure including a root that is the highest hierarchy, and nodes in a lower hierarchy connected by an edge from the root,
A node arrangement step of arranging one or more nodes in a lower hierarchy connected by edges so that each node does not overlap with each other radially from a root or a higher hierarchy node;

When the node erased by the reduced display step is focused, the focus is set to the direct upper node of the node focused before being erased and the node of the lowest hierarchy made displayable by the display hierarchy determining step. A focus movement step to move,
It is characterized by providing.

  According to the information display method of the present invention, the same effects as the information display program can be achieved for the reasons described above.

  According to the information display program and the information display method of the present invention, the target node can be focused by an intuitive operation on one continuous screen, and the current focus is particularly high when the data hierarchy is deep. When the focus is transferred from the node being focused to another node, a special operation for closing the currently focused node is unnecessary, and as a result, the target node can be quickly found.

  Further, as another effect of the present invention, nodes having similar meanings are associated with each other by hierarchical related information, so that even nodes of different systems can be easily searched for nodes having similar meanings.

  Embodiments of an information display program and an information display method according to the present invention will be described below in detail with reference to the accompanying drawings. The information display program of the present invention is executed by a computer constituting the information display system, and the information display method of the present invention is realized by executing the program.

  FIG. 1 is a block diagram of an information display system 1 for executing an information display program according to a preferred embodiment of the present invention. FIGS. 15 to 17 are an information display program and an information display method according to an embodiment of the present invention. It is a figure explaining the example of the data of the tree structure displayed by. As shown in FIG. 1, the information display system 1 includes a medical information database 2, a control unit 3, an input unit 4, a display unit 5, and a storage unit 10.

  The medical information database 2 includes electronic medical record data storing patient information, disease information, prescription information, surgery information, etc., medical accounting data storing insurance medical treatment points, medical fees, etc., purchase inventory of medicines, gauze, etc. Distribution data storing information and the like, financial data storing information such as amounts of various purchased items, labor costs, and the like are stored. These data are collected by another tabulation analysis tool, and each is stored as a meaningful table. This table may be stored in either the medical information database 2 or the storage unit 10.

  The control unit 3 is configured by a CPU or the like, and performs various processes necessary for the operation of the information display system 1 independently or in cooperation with other components.

  The input unit 4 is for accepting an operation by an operator, and a known keyboard, mouse, trackball, touch panel, or the like is employed.

  The display unit 5 visually displays information on the medical information database 2 and the storage unit 10 processed by the control unit 3, information input by the input unit 4, contents of processing executed by the control unit 3, and the like. It is displayed as typical information.

  The storage unit 10 includes a program storage area 11 and a work area 31. The program storage area 11 includes a node placement unit 12, an initial display unit 13, a selection receiving unit 14, an enlargement rate changing unit 15, a display hierarchy determining unit 16, an enlarged display unit 17, a node erasing unit 18, a reduced display unit 19, and a focus. The moving means 20, the hierarchy display means 21, the hierarchy related information holding means 22, the hierarchy related information comparison means 23, the node option display means 24, and the detailed processing means 25 are provided as programs. These programs execute each means that is a component of the information display program according to the present embodiment in cooperation with the control unit 3 and the like. Further, the program storage area 11 further includes a basic program such as an operating system (not shown) and various programs necessary for the operation of the information display system 1. Further, the work area 31 includes hierarchical related information storage means 32 and temporary work storage means (not shown) for storing temporary information necessary for the operation of the information display system 1.

  The node arrangement means 12 arranges one or more nodes in the lower hierarchy connected by edges from the root or higher hierarchy nodes in a radial manner from the root or higher hierarchy nodes so that each node does not overlap. In the displayable area where nothing is displayed, the length of the edge and the angle of the adjacent edge are calculated according to the number of nodes in the lower hierarchy, and the edge and the node are arranged. In principle, the node arrangement unit 12 always functions during execution of the information display program of the present embodiment.

  When the information display program of this embodiment is executed, the initial display means 13 displays a root or a node of a predetermined upper layer including the root on the screen as an initial screen. In the present embodiment, the root and the first hierarchy node are displayed as the initial state, and the root and the first hierarchy node are displayed on the screen no matter how much the screen display is reduced by the reduced display means 19. The setting is displayed.

  The selection receiving unit 14 focuses a desired route or node by a predetermined operation performed by the operator. For example, the selection receiving unit 14 automatically focuses the route or node closest to the center of the screen, or A desired route or node can be focused by clicking with the mouse or tapping on the screen. Alternatively, a node that is focused by clicking with the mouse or tapping on the screen may be forcibly moved to the center of the screen.

  The enlargement ratio changing means 15 enlarges or reduces the initial screen displayed by the initial display means 13 to a desired enlargement ratio by a predetermined operation performed by the operator, and rotates the mouse wheel or pinches in the screen. Accept operations such as pinch-out and reflect them in the screen magnification.

  The display hierarchy determining means 16 determines what level can be displayed according to the enlargement ratio of the screen changed by the enlargement ratio changing means 15, for example, an enlargement ratio less than 1.5 times from the initial screen. In the initial screen, the root and the first layer can be displayed, and when the magnification rate is 1.5 times or more and less than 2.25 times, the second layer can be displayed, and the magnification rate is 2.25 times or more and less than 3.38 times. Then, it is possible to display up to the third level.

  The enlarged display means 17 is configured such that when the screen is enlarged and the display hierarchy determining means 16 can display up to a predetermined lower hierarchy, the hierarchy of the node focused by the selection receiving means 14 is determined as the display hierarchy determination. If the hierarchy is higher than the hierarchy that can be displayed by the means 16, the direct node in the hierarchy immediately below the focused node is displayed. Thus, by focusing a desired node in a state where the screen is enlarged, or by enlarging the screen in a state where the desired node is focused, a node in a lower hierarchy of the focused node is automatically displayed on one screen. Can be displayed continuously.

  When the focus is moved from the node focused by the selection receiving unit 14 to another node in the same hierarchy or higher hierarchy, the node erasure means 18 selects the other node among the nodes in the lower hierarchy of the other node. Nodes other than the direct node in the hierarchy immediately below the node are deleted from the screen. As a result, by simply moving the focus to another node, unnecessary lower-level nodes can be automatically deleted from the screen, and the operation can be simplified. Note that it may be possible to select whether to enable or disable the operation of the node erasing means 18.

  The reduced display means 19 determines the display hierarchy when the hierarchy that can be displayed by the display hierarchy determination means 16 is moved up to a hierarchy higher than the node hierarchy displayed on the screen by reducing the screen. The node lower than the hierarchy that can be displayed by the means 16 is deleted from the screen. As a result, it is possible to delete a lower layer node from the screen only by reducing the screen.

  When the node erased by the reduced display means 19 is focused, the focus moving means 20 can be displayed by the direct upper node of the node focused before being erased and by the display hierarchy determining means 16 The focus is transferred to the lowest level node. As a result, when a lower-level node is deleted, the focus is automatically moved, and there is no need to newly refocus. Further, by cooperation of the various means described above, it is possible to continuously display or delete lower-level nodes on one screen only by enlarging or reducing the screen.

  The hierarchy display means 21 displays all the nodes up to a predetermined hierarchy within the range of the lower hierarchy that can be displayed by the display hierarchy determination means 16 regardless of the hierarchy position of the node focused by the selection accepting means 14. It is what is displayed. For example, when the hierarchy display means 21 is set to display up to the second hierarchy in advance, and the display hierarchy determination means 16 enables the display of the hierarchy below the second hierarchy, even if the focus is at the root, the first hierarchy And all the nodes of the second hierarchy are forcibly displayed. Therefore, when the number of nodes in each hierarchy is small, the entire tree-structured data can be easily grasped by using the hierarchy display means 21. Further, the hierarchy displayed by the hierarchy display means 21 is not limited to the number of hierarchies, but when there are N layers of tree-structured data, N = 1 and so on are calculated backward from the hierarchy including the terminal node. It can also be set. Moreover, you may enable it to select whether operation | movement of the hierarchy display means 21 is validated or invalidated.

  The hierarchical related information storage means 32 stores information for associating nodes having similar meanings for each hierarchy with each other, and assigns common hierarchical related information to nodes having similar meanings in advance. The nodes having similar meanings are related by the hierarchical related information. Thereby, even if the nodes are of different systems, for example, nodes having similar meanings representing the number of patients, medical subjects, and the like can be associated with each other.

  The hierarchical related information holding means 22 holds the hierarchical related information according to a predetermined operation performed by the operator when hierarchical related information is given to the focused node. Note that holding is intended to be sufficient if it can be temporarily stored, and here, the word “holding” is used in order to distinguish it from the related information storage means 32 according to hierarchy. The hierarchical related information held by the hierarchical related information holding means 22 is information necessary for executing the hierarchical related information comparing means 23 and the node option display means 24 described later. When the information comparison unit 23 and the node option display unit 24 have been executed, the holding may be released. In addition, for a predetermined operation performed by the operator to hold the hierarchically related information, for example, a method of clicking the target node with a mouse or directly pressing and holding the screen with a finger or the like can be employed.

  The related information comparing unit 23 classified by hierarchy, when the focus is moved from the node holding the related information classified by hierarchy to the root or another node of the upper hierarchy by the selection receiving unit 14, the route to which the focus has been moved Alternatively, the hierarchical related information of the nodes lower than the node is compared with the retained hierarchical related information. As a result, it is determined whether or not there is a node related to the node holding the related information for each hierarchy in the lower-level nodes of the root or the node to which the focus has been moved, and if there is, Nodes can be specified.

  The node option display means 24 newly focuses the node having the hierarchical related information that is compared by the hierarchical related information comparing means 23 and that completely or partially matches the retained hierarchical related information. It is displayed as a node candidate. This makes it possible to present to the operator a node related to the node that holds the hierarchical related information, and saves the operator from having to search. When candidates for a node to be newly focused are displayed, the node may be directly displayed on the screen, or a plurality of candidates may be collected in a list or the like.

  The detailed processing unit 25 performs another predetermined process when a predetermined operation is performed on the focused node. This other predetermined processing includes displaying detailed data related to the node, starting another program, and the like. In addition, as the predetermined operation, for example, a method of double-clicking the node with a mouse or double-tapping the node on the screen can be adopted. Further, the detailed processing means 25 can be executed in parallel by a plurality of nodes. For example, the detailed processing means 25 can be executed in all of one or more focused nodes among the nodes in which the hierarchical related information is held and the nodes displayed by the node option display means 24. By doing in this way, it is possible to compare detailed information of related nodes.

  Next, with reference to FIG. 15 to FIG. 17, the details of the hierarchical related information storage means 32 and the hierarchical related information will be described. The tables shown in FIGS. 15 to 17 are examples of tables storing the names of the roots and nodes of each hierarchy of the tree structure data displayed by the information display program and the information display method according to the present embodiment. . In these tables, the route is described in the left column and the lowest layer node is described in the right column. The tree structure data displayed in the present embodiment has three routes, “financial analysis” shown in FIG. 15, “external analysis” shown in FIG. 16, and “hospital analysis” shown in FIG. , Nodes (items) from the first layer to the third layer are provided. The nodes in the third hierarchy are for each medical subject, and each node includes “internal medicine”, “surgery”, “orthopedics”, and “otolaryngology”.

  In addition, among the nodes in each hierarchy, related information classified by hierarchy is given to nodes having similar meanings. For example, in the first hierarchy “patient information” of the route “outpatient analysis” shown in FIG. 16 and the first hierarchy “patient information” of the route “hospital analysis” shown in FIG. The second hierarchy “number of outpatients” in the first hierarchy “patient information” of the route “outpatient analysis” shown in FIG. 16 and the first hierarchy “patient information” in the first hierarchy “patient information” shown in FIG. The same information related to each hierarchy “2A” is given to the “hierarchical discharge number” in the second hierarchy, and the “internal medicine”, “surgery”, “orthopedics”, and “otolaryngology” common to all the third hierarchy are assigned to Different related information “3A”, “3B”, “3C”, and “3D” are given. Similarly, related information according to hierarchy is given to other nodes having similar meanings. In this way, the hierarchical related information storage means 32 stores the hierarchical related information in the table storing the root and the name of the node of each hierarchy, and associates nodes having similar meanings. It is. Note that, when there are no other nodes having similar meanings, such as nodes in the first and second layers of the table shown in FIG.

  Next, based on the function of each component described above, the operation of the information display program of the present embodiment will be described with reference to FIGS. In the information display method of the present embodiment, it can be understood by replacing “means” of each component with “step”.

  First, referring to FIG. 1 to FIG. 6, the node arrangement unit 12, the initial display unit 13, the selection receiving unit 14, the enlargement ratio changing unit 15, and the display hierarchy determining unit 16 of the information display program of this embodiment. The enlarged display unit 17 and the detailed processing unit 25 will be described. FIG. 1 is as already described. 2 is a diagram for explaining an initial screen on which a route and a first hierarchy are displayed, FIG. 3 is a diagram for explaining a screen on which an enlarged second hierarchy is displayed, and FIG. 4 is further enlarged and a third hierarchy is displayed. FIG. 5 is a diagram for explaining a screen on which detailed data is displayed, and FIG. 6 is an enlarged view of FIG.

  When the information display program of this embodiment is executed, as shown in FIG. 2, the initial display means 13 displays the route and the first layer node connected by the route and the edge. Here, the node arrangement means 12 arranges the nodes of the first hierarchy in a radial manner from the root so that the respective nodes do not overlap. In the state of FIG. 2, all the nodes around the route are arranged and displayed. In such a case, the edges are arranged so that the edges of the nodes of the first layer are substantially evenly radiated and the distance between the route and the node is appropriate. In addition, the frame shown with the broken line in FIG. 2 shows the area | region which can be displayed on an actual screen, and the small frame of "financial analysis" "outpatient analysis" "hospitalization analysis" displayed on the upper left of the said frame is This is a button on the screen for selecting a route (the same applies to FIGS. 3 to 13).

  In addition, the selection receiving unit 14 focuses a desired route or node. However, in the information display program of this embodiment, in principle, the route or node closest to the center of the screen is set to be focused. In FIG. 2, the route is closest to the center of the screen, and the route (hatched display) is focused. Also, when changing the route itself, it is possible to switch the desired route in the small frame at the upper left of the screen by clicking with the mouse or tapping the screen.

  Next, as shown in FIG. 3, the screen display is enlarged and moved by 1.5 times by the enlargement ratio changing means 15, and the first layer node displayed in the upper right of the screen in FIG. The node (hatched display) is focused by the selection receiving unit 14. In addition, since the enlargement factor changing unit 15 enlarges the initial screen by 1.5 times, the display layer determining unit 16 can display up to the second layer. Since the currently focused node is the first hierarchy, the enlarged display means 17 displays the second hierarchy node, which is a direct node of the hierarchy immediately below the focused node, on the screen. The

  At this time, the node arrangement means 12 arranges the nodes of the second hierarchy in a radial manner from the nodes of the first hierarchy and does not overlap each other, but as shown in FIG. If there is a route that is a higher layer on the lower left side of the first layer, the route is arranged so that the edge of the second layer side does not extend on the route side, and the focused first layer node and the other first layer It is preferable to arrange the nodes in the second hierarchy so that the separation distance from the nodes in the hierarchy is appropriate. This is because it is possible to prevent a node in a lower hierarchy from overlapping with a node in an upper hierarchy even if the hierarchy is deepened. In addition, when the number of nodes is large, it is possible to prevent the adjacent nodes from overlapping by increasing the edge.

  Next, as shown in FIG. 4, the screen display is enlarged and moved by 2.25 times by the enlargement ratio changing means 15, and in FIG. 3, the second layer node displayed at the upper left of the screen is the center of the screen. The node (hatched display) is focused by the selection receiving unit 14. Further, since the enlargement ratio changing means 15 has enlarged 2.25 times from the initial screen, the display hierarchy determining means 16 can display up to the third hierarchy. Since the currently focused node is the second hierarchy, the enlarged display means 17 displays the third hierarchy node, which is a direct node of the hierarchy one level lower than the focused node, on the screen. The The node arrangement means 12 determines the arrangement of the third layer nodes as well, but as with the second layer, the arrangement is made so that the edge does not extend to the root side, and an appropriate separation distance from other nodes is set. It is preferable to keep it arranged.

  Next, as shown in FIG. 5, when the screen display is moved and the third layer node displayed in the upper center of the screen in FIG. (Hatched display) is focused. At this time, when a predetermined operation such as double tap or double click is performed on the focused node, the detailed processing unit 25 displays detailed data regarding the node in another window 26. At this time, the selection receiving unit 14 causes the focus to be obtained by performing an operation such as clicking the third layer node displayed on the upper center of the screen in FIG. 4 with a mouse or tapping the screen. To forcibly move the node to the center of the screen.

  FIG. 6 shows a screen when this detailed processing means 25 is executed, and shows a state in which detailed data of “the number of inpatients by medical department (gender)” is displayed in another window 26. is there. Then, the display in the separate window 26 is scrolled by the scroll bar at the bottom of the separate window 26, or the separate window 26 is closed by the “close” button at the upper right of the separate window 26, and the processing of the detailed processing means 25 is finished. Can be made. The separate window 26 can be displayed in a full screen size.

  Next, returning to FIG. 4 and referring to FIGS. 7 and 8, the reduced display means 19 and the focus moving means 20 will be described. FIG. 7 is a diagram for explaining a screen in which the screen in FIG. 4 is reduced and the third layer is deleted, and FIG. 8 is a diagram for explaining a screen in which the second layer is deleted after further reduction.

  In FIG. 4, as described above, the initial screen is magnified 2.25 times by the selection receiving means 14, the enlargement ratio changing means 15, the display hierarchy determining means 16, and the enlarged display means 17. A node in the hierarchy is focused and a node in the third hierarchy is displayed.

  When the screen displayed in FIG. 4 is reduced by the enlargement factor changing means 15 to an enlargement factor of 1.5 times from the initial screen, the display hierarchy determining means 16 can display up to the second hierarchy. Then, as shown in FIG. 7, the displayed node of the third hierarchy is deleted by the reduced display means 19, and the nodes up to the second hierarchy are displayed. At this time, since the focused node (hatched display) is not erased, it remains focused.

  Further, when the screen shown in FIG. 7 is reduced by the enlargement ratio changing means 15 to a magnification of 1 time from the initial screen, the display hierarchy determining means 16 can display up to the first hierarchy. Then, as shown in FIG. 8, the reduced display means 19 deletes the displayed second-level node, and the focus moving means 20 deletes the second-level node focused before being deleted. The focus is moved to the first-level node (hatched display) that is the direct hierarchy and the lowest hierarchy that can be displayed by the display hierarchy determination means 16. At this time, in order to make the screen easier to see, the focused node can be set to be forcibly arranged at the center of the screen.

  Further, when the screen shown in FIG. 8 is scrolled and the route is moved to the center of the screen, the route is focused by the selection accepting unit 14, and the same screen as the initial screen shown in FIG. 2 can be obtained.

  Next, the node erasing means 18 will be described with reference to FIGS. FIG. 9 is a diagram illustrating a screen in which the focus is moved from the focused node in FIG. 4 to another node in the same hierarchy. In FIG. 4, it has already been described that the enlargement ratio changing means 15 enlarges the image to 2.25 times from the initial screen, and the display hierarchy determining means 16 can display up to the third hierarchy. Then, the leftmost node among the opened second hierarchy nodes is focused, and the third hierarchy node that is a direct node of the hierarchy immediately below the relevant node is displayed.

  Here, as shown in FIG. 9, the screen is scrolled without changing the enlargement ratio of the screen, and the other nodes on the two right sides in the same hierarchy from the focused second node in FIG. 4. When the focus is moved to (hatched display), since the display hierarchy determining means 16 can display up to the third hierarchy, the third hierarchy node that is a direct node of the hierarchy one level lower than the other nodes is displayed. Is displayed. On the other hand, if a direct node (a node indicated by a broken line) in the lower hierarchy of the node before the focus is moved is left as it is, more nodes are opened each time the focus is moved to another node in the same hierarchy. There is a risk that nodes overlap each other in the screen. Therefore, when the focus is moved to another node of the same hierarchy displayed at that time, the node in the hierarchy one level lower than the other node among the nodes of the lower hierarchy than the other node (hatched display). A node represented by a broken line, which is a node other than the direct node, is erased by the node erasure means 18. Here, when the focus is moved to the first hierarchy of the upper hierarchy, the node erasure unit 18 selects the other node among the nodes of the lower hierarchy than the other focused nodes (first hierarchy). Since nodes other than the direct node (second layer node) in the next lower layer are deleted from the screen, all the third layer nodes are deleted from the screen.

  Next, the hierarchy display means 21 will be described with reference to FIG. FIG. 10 is a diagram for explaining a screen on which all nodes up to a predetermined lower hierarchy are displayed by the hierarchy display means 21. Here, as shown in FIG. 10, when the enlargement ratio changing means 15 enlarges 1.5 times or more from the initial screen, and the display hierarchy determining means 16 can display a hierarchy deeper than the second hierarchy, the hierarchy display Regardless of the position of the focused node, the means 21 is set to display all the nodes up to the second layer in advance. Since all the nodes up to a predetermined hierarchy can be displayed by the display hierarchy determining means 16, there is an effect that it becomes easy to find a target node when the number of nodes in the predetermined hierarchy is small.

  Next, with reference to FIGS. 11 to 17, the hierarchical related information storage unit 32, the hierarchical related information holding unit 22, the hierarchical related information comparison unit 23, and the node option display unit 24 will be described. FIGS. 11 to 13 are diagrams for explaining screens on which candidate nodes to be newly focused are displayed by the node option display means 24, and FIG. 14 is a flowchart for explaining processing for displaying related node candidates. 15 to 17 are as already described.

  First, as a premise, an arbitrary node needs to be focused. Here, for example, in the table shown in FIG. 16, nodes related to the route “outpatient analysis”, the first layer “patient information”, the second layer “number of outpatients”, and the third layer “internal medicine” are focused. (FIG. 16 thick frame “* 1”). At this time, the hierarchical related information holding unit 22 determines whether an operation for holding the hierarchical related information, for example, an operation of pressing and holding a node on the screen or the like has been performed. This determination is repeated (FIG. 14, S1010). Here, when the operation for holding the hierarchical related information is performed, the hierarchical related information holding means 22 also performs the first hierarchy “patient information”, the second hierarchy “outpatient number”, and the third hierarchy “internal medicine”. The hierarchically related information “1A”, “2A”, and “3A” assigned to each are stored (FIG. 14, S1020).

  Next, it is determined by the hierarchical related information comparison means 23 whether or not the focus has been moved to the root or a node higher than the node that has been focused so far (FIG. 14, S1030). Here, if the focus is not transferred to another node, or if the focus is the same level or lower level, the determination in step S1030 is repeated. On the other hand, when the focus is moved to the root or a higher-level node, for example, the selection reception means 14 selects “hospital analysis” (see FIG. 13) in the upper left frame of the screen, and the focus is the route shown in FIG. When transferred to “hospital analysis”, the hierarchical related information comparing means 23 also refers to hierarchical related information attached to nodes lower than the root, that is, nodes belonging to the hierarchy below the first hierarchy ( 14, S 1040), whether or not the hierarchical related information “1A”, “2A”, and “3A” held by the hierarchical related information holding means 22 and the hierarchical related information referenced in step S 1040 completely match. Judgment is made (FIG. 14, S1050).

  Here, the hierarchy-related related information “1A”, “2A”, “3A” assigned to the first hierarchy “patient information”, the second hierarchy “number of hospitals / discharges”, and the third hierarchy “internal medicine” (FIG. 17 bold frame “* 2 )) Completely matches the hierarchical related information “1A”, “2A”, and “3A” held by the hierarchical related information holding means 22. Therefore, as shown in FIG. 11, the node option display means 24 displays a completely matched node as a node candidate to be newly focused (FIG. 14, S1060). Then, the node is focused by clicking the node with the mouse or tapping the screen. Note that when a node candidate to be newly focused is displayed in step S1060, the node closest to the center of the screen is not focused in FIG. 11, and the route determined in step S1030 remains focused (hatched display). However, it may be set so that the focus is automatically transferred to the node of the third hierarchy “internal medicine” of the displayed candidate.

  Next, after holding the hierarchical related information by the hierarchical related information holding means 22, the operation is performed when the focus is moved only to the lower hierarchy of the root, and a part of the compared hierarchical related information matches. Will be explained. Here, if the nodes in the table shown in FIG. 16 relating to the root “outpatient analysis”, the first layer “patient information”, the second layer “number of outpatients”, and the third layer “internal medicine” are focused. (FIG. 16 thick frame “* 1”). Then, an operation for holding the hierarchical related information is performed (S1010), and the hierarchical related information “1A”, “2A”, and “3A” are held (S1020).

  Next, it is assumed that the focus is moved to the first hierarchy “diagnosis information” in FIG. 16 which is the same route (S1030). Then, the hierarchical related information comparing means 23 refers to the hierarchical related information of the lower hierarchy, that is, the nodes of the second and third hierarchies than the node to which the focus has been moved (S1040). Similarly, among the hierarchical related information “1A”, “2A”, and “3A” held in step S1020 by the hierarchical related information comparison unit 23, the second hierarchy and the third hierarchy referenced in step S1040 are classified by hierarchy. The second layer related information “2A” and the third layer related information “3A” corresponding to the related information include the second layer and the third layer related information referred to in step S1040. It is determined whether or not they completely match (S1050).

  Here, since there is no hierarchically related information that completely matches, the hierarchical related information comparison unit 23 then holds the related information “2A” of the second hierarchy and the related information “3A of the third hierarchical level that are held. Is partially matched, that is, whether or not the second layer and the third layer related information referred to in step S1040 are matched (S1070). Here, the hierarchical related information “3A” of the nodes related to the “internal medicine” of the third hierarchy matches (FIG. 16, bold frames “* 3”, “* 4”, “* 5”, “* 6”). Therefore, as a partially matching node, 1. 2nd hierarchy "Ranking by disease" "2E", 3rd hierarchy "Internal medicine" "3A", 2. 2. Second hierarchy “patient average consultation hours” “2F”, third hierarchy “internal medicine” “3A”; 2nd hierarchy "Number of outpatient surgery" "2G", 3rd hierarchy "Internal medicine" "3A", 4. The second hierarchy “outpatient surgery rate” “2H” and the third hierarchy “internal medicine” “3A” are displayed as candidate nodes to be newly focused (S1080).

  An example of the screen displayed in step S1080 is as shown in FIG. This is because the second layer nodes are “disease ranking”, “patient average consultation hours”, “outpatient surgery number”, and “outpatient surgery rate”, respectively, and the third layer nodes are “internal medicine”. The node related to the node related to the layer-related information held in step S1010 is displayed as a node candidate to be newly focused. In this case as well, the node closest to the center of the screen is not focused, but the node moved in step S1030, that is, the first layer node remains focused (hatched display). The focus condition can be changed as appropriate according to the situation.

  Another example screen displayed in step S1080 is shown in FIG. Here, the node candidates to be newly focused displayed in step S1080 can be selected from a list, by clicking a desired node with the mouse or tapping the screen. Then, after the selection, for example, the node can be directly displayed as shown in FIG.

  In addition, when there are a plurality of node candidates to be newly focused as described above, the detailed processing means 25 is executed on the node related to the retained hierarchical related information, and the new candidate node is focused, After the detailed processing means 25 is executed in parallel, another candidate node is focused, and the detailed processing means 25 is also executed for this node, and the detailed processing means 25 is executed in parallel with a plurality of related nodes. It is also possible to execute and compare detailed data related to each node. Also, in the process of comparing the layer-related information held in step S1020 described above with the layer-related information referred to in step S1040, either step S1050 or step S1070 may be omitted.

  Further, in step S1070, the second layer related information “2A” and the third layer related information “3A” held in step S1070, and the second layer and third layer related information referenced in step S1040. If the information does not match at all, it is displayed on the screen that there is no related node (S1090), and the process is terminated (S1100).

  As described above, according to the information display program and the information display method of the present embodiment, by automatically enlarging the screen in a state where the node is focused, the node in the lower hierarchy of the focused node is automatically displayed. The target node can be found and focused by an intuitive operation on one continuous screen.

  Also, especially when the data hierarchy is deep, when moving the focus from the currently focused node to another node, simply moving the focus to another node or reducing the screen, unnecessary lower layers Can be deleted from the screen, and the operation can be simplified. Further, when the screen is reduced in a state in which the node in the lower hierarchy is focused, and the node is deleted from the screen, the focus can be automatically moved to the directly higher node. As a result, a special operation for closing the focused node is unnecessary, and as a result, the target node can be quickly found.

  In addition, since nodes having the same meaning are associated with each other according to hierarchical related information, it is possible to easily search other related nodes while referring to detailed information of a certain node. It is also possible to display detailed information of other searched nodes and compare detailed information of a plurality of related nodes.

  The information display program and the information display method described above are examples of the present invention, and the configuration thereof can be changed as appropriate without departing from the spirit of the invention. For example, as long as the same effect is brought about, the order of the processes related to the above-described components may be changed. Further, each of the above-described components can be replaced with other equivalent means.
