BACKGROUND OF THE INVENTION
  The present invention provides an information presentation device,Information presentation method, Information presentation program, and storage mediumMore specifically, the information presentation device in the information management system that manages the shared information shared by a plurality of users in a hierarchical structure,Information presentation method, Information presentation program, and storage mediumAbout.
[0002]
[Prior art]
Conventionally, in an office or the like, an information management system for managing information shared by a plurality of users using a hierarchical structure is used. For example, FIG. 8 shows an example of a display screen in the case where conventional shared information is managed in a hierarchical structure, (a) is a diagram in the case of managing with the folder tree 81, and (b) is a hyperlink 82. FIG. As shown in FIGS. 8A and 8B, since the shared information is used by a plurality of users, the access frequency differs depending on the information tendency required by the users. For this reason, even if a large amount of shared information is managed using a hierarchical structure, it is necessary for the user to select several levels before reaching the desired information.
[0003]
For example, in this type of conventional example, ranking is displayed in the order of files with the highest access frequency, and those with low access frequency but with high importance can be ranked higher so that the user's intention is given priority. There was what was made possible (see Patent Document 1).
[0004]
Moreover, there existed some which show the popularity of information according to access frequency (refer patent document 2).
[0005]
In addition, there is one that automatically generates display format information including a three-dimensional expression according to the access frequency of a Web page and displays it on a network subscriber (see Patent Document 3).

[Problems to be solved by the invention]
However, in such a conventional information presentation apparatus, when sharing information is managed in a hierarchical structure, each user can easily and quickly find the target information from the shared information. Is required. From the viewpoint of one user, this has the following features (1) to (6). (1) A lot of information unrelated to oneself is also stored, but usually only information in several specific layers (folders and links) is accessed. (2) Hierarchical division and folder (or link) nomenclature are often decided systematically or assigned by other people, so they may not be used to their own taste. In particular, it is still difficult for the user who accesses the hierarchical structure for the first time. (3) Hierarchical names (folders and links) may be assigned to different subtrees. For example, FIG. 9 is a diagram in the case where conventional shared information is managed and displayed in a folder tree. The folder tree 93 is divided into a hierarchical structure, and a hierarchical name similar to a subtree name (theme management 92) ( 30 general management 91) may be added. (4) The hierarchical structure may change (nodes or hierarchies will increase or disappear) or new information may increase without your knowledge. (5) Some information is accessed only occasionally (end of period, beginning of period) instead of being accessed frequently. (6) Depending on how information is classified, the hierarchy may become deeper or the information contained in one hierarchy may increase.
[0008]
As described above, the shared information managed in the hierarchical structure has the above-described characteristics, and thus the following problems can be considered for the accessing user. In other words, from the features (1) and (6), there is a problem that a layer (folder or link) that is not related to the user has to be traced in the middle of reaching the target information.
[0009]
Further, from the features (2) and (6), if a lot of information is stored in one layer, there is a problem that it is difficult to specify the target information at a glance.
[0010]
Furthermore, from the features (2) to (4) and (5) above, it becomes difficult to distinguish the name of the target folder (or link), and it becomes difficult to recognize, so it is easy to get lost in the hierarchical structure. Problem arises.
[0011]
In addition, with respect to the above-mentioned Patent Document 1, as a display different from the hierarchical structure, the order of files with the highest access frequency, or the items with high importance even though the access frequency is low are displayed in the file list. Although it is possible to determine what is a frequently accessed file or a highly important file, there is a problem in that it cannot be determined where the file is positioned in relation to the hierarchical structure.
[0012]
Furthermore, with respect to the above-mentioned Patent Document 2, the degree of popularity of information is presented according to the access frequency, and the same degree of popularity information is presented to all users. For this reason, it is possible to know the frequency of access to which information and how many times the information has been accessed for the entire user, but since each user has a different access tendency, each user uses the hierarchical structure to follow the target information. There was a problem that could not be helpful.
[0013]
Also, with respect to the above-mentioned Patent Document 3, display format information including a three-dimensional expression is automatically generated according to the access frequency of a Web page and displayed to a network subscriber. For this reason, although it is possible to display the access frequency of the Web page, the type of address, or the size according to the access frequency, etc., it is related to the network resource having the address, and each user's It is difficult to grasp where the shared information to be used is located in the hierarchical structure, and there is a problem that it cannot be used as a reference when tracing the target information using the hierarchical structure.
[0014]
The present invention has been made in view of the above, and by providing a personal view added to the hierarchical structure to the user according to the frequency with which the user accesses each hierarchical layer, each user can It is an object of the present invention to provide an information presentation apparatus and an information presentation method capable of easily and quickly accessing target information simply by referring to the structure.
[0015]

DETAILED DESCRIPTION OF THE INVENTION
  An information presentation device according to the present invention will be described below with reference to the accompanying drawings.,Information presentation method, Information presentation program, and storage mediumThe preferred embodiment will be described in detail.
[0036]
(Embodiment 1)
The present invention is applied to an information management system that manages shared information in a hierarchical structure using a folder tree or a hyperlink (see FIGS. 8A and 8B). In the first embodiment, for example, an information management system that collectively manages shared information in the company is constructed, and employees can freely access shared information from each terminal (personal computer) via a LAN or the like. I will explain it.
[0037]
FIG. 1 is a diagram illustrating a schematic configuration of the information presentation apparatus 10 according to the first embodiment. 1 is an access frequency statistics unit 11 as an access frequency statistics unit, an access frequency vector storage unit 12 as an access frequency information storage unit, a group determination unit 13 as a group determination unit, and a group information storage unit. Group table storage unit 14, a hierarchical structure display unit 15 as a hierarchical structure display unit, a shared information storage unit 16 as a shared information storage unit, and the like. When a hierarchical structure display request is made to the information presentation apparatus 10 from the user 17 who uses the shared information, in addition to the original hierarchical structure, a personal view regarding at least the access frequency for each hierarchy of the user 17 is displayed. This information is generated and presented to the user 17.
[0038]
The access frequency statistics unit 11 is activated every time the user 17 issues a hierarchical structure display request. When the user 17 accesses the hierarchical structure, the user (UserID) is notified via the hierarchical structure display unit 15. However, when information on which layer (hierarchy ID) is accessed is received, the vector of the user is extracted from the access frequency vector storage unit 12, and the access frequency of the corresponding layer is incremented (+1). Then, by returning this vector to the access frequency vector storage unit 12, the statistical result of the access frequency is stored in the access frequency vector storage unit 12.
[0039]
The access frequency vector accumulation unit 12 accumulates access frequency vectors for each user and manages them.
[0040]
The group determination unit 13 is activated by an external input or access frequency vector storage unit 12. For example, if there is an external input, the result of the external input is reflected in the group table storage unit 14 as it is. If there is no external input, the group to which each user belongs is calculated using the vector stored in the access frequency vector storage unit 12. FIG. 2 shows an example of a group table stored and managed in the group table storage unit. FIG. 2A is a diagram of the group table 21 representing a group to which a user belongs, and FIG. 2B shows a group. It is a figure of the group member table 22 showing a member. In the group table storage unit 14, two tables as shown in FIGS. 2A and 2B are stored and managed. And the group determination part 13 is producing | generating and correcting the group table shown to this Fig.2 (a), (b).
[0041]
The hierarchical structure display unit 15 is basically activated in response to a hierarchical structure display request from the user 17, and generates and displays the original hierarchical structure and a personal view that is a feature of the present invention to the user 17. . When displaying the original hierarchical structure, the hierarchical structure is generated by using the shared information stored in the shared information storage unit 16. When displaying a personal view, the member table of each group to which the user belongs belongs from the group table storage unit 14 (both the group table 21 and the group member table 22 in FIGS. 2A and 2B are used). ) And the vectors of the user himself / herself and all the member lists are extracted from the access frequency vector storage unit 14. Then, based on these pieces of information, a personal view of the user himself / herself is generated.
[0042]
The shared information storage unit 16 exists as a part of a conventional information management system, and stores and manages the shared information constituting the original hierarchical structure.
[0043]
The information presentation apparatus according to the first embodiment is configured as described above, and processing is performed according to the following procedure.
[0044]
FIG. 3 is a display example of a hierarchical structure when a personal view is generated by changing the original hierarchical structure, (a) is a diagram showing the original hierarchical structure, and (b) is a hierarchical structure with a personal view. FIG. FIG. 4 is a diagram showing a hierarchical structure to which a personal view is added without changing the original hierarchical structure. FIG. 5 is a flowchart for explaining the main routine of the first embodiment, and FIG. 6 is a flowchart for explaining a subroutine of the group determination process in FIG.
[0045]
First, as shown in FIG. 1 and FIG. 5, whenever each user 17 accesses a hierarchy (here, a folder, but a hierarchy in the case of a hyperlink, it becomes a link), the hierarchy of that user (i) Each access frequency vector V (i) = (l_i1, l_i2, ... l_im) Is recalculated (for example, 1 is increased) (step S500). Where l_ijIs the hierarchy l_ijRepresents the access frequency. The calculation result of the access frequency is stored in the access frequency vector storage unit 12 (step S501). The operation when the group determination process is performed in step S501 will be described later.
[0046]
Subsequently, in step S502, it is determined whether or not there is a hierarchical structure display request from an arbitrary user (i). If there is a display request, a personal view related to the user who requested the display is displayed on the hierarchical structure display unit 15. It is made to generate (step S503). If there is no display request, the process returns to step S500 and the above process is repeated.
[0047]
As for the personal view generation process, for example, as shown in FIG. 3, the hierarchy most frequently accessed by the user who made the display request can be brought to the top hierarchy and displayed. That is, the access frequency vector (l_i1, l_i2,… L_im ), The largest top K (here, K = 3) hierarchies (folders or links) are displayed together with the root hierarchies. At this time, as shown in FIG. 3 (b), the original hierarchical structure 31 shown in FIG. 3 (a) is displayed as it is, and if it is not easy to arrange the K hierarchies in the same hierarchy, Among them, a layer other than the top M access frequencies (here, M = 1) is folded to the next lower layer and displayed as shown in FIG. 3B (step S504). Here, K and M described above are arbitrary threshold values predetermined in each system, and are not limited to these values.
[0048]
As another display example for generating a personal view related to the requested user in step S503 in FIG. 5, the access frequency corresponding to each layer is visualized using the access frequency vector of the user. You can also For example, as shown in FIG. 4, a numerical value of the access frequency of the user himself / herself is displayed next to each folder name in the original hierarchical structure 31 (indicated by numerals 42, 43, 44, 45, 46 in FIG. 4). Although not shown, the folder names can be identified at a glance by color-coding according to the access frequency, or a color bar proportional to the access frequency is displayed next to the folder name (not shown). Also good. Further, in this case, not only the access frequency of the user but also the access frequency of other users in the group to which the user belongs may be visualized (for example, corresponding to the number 41 with a star in FIG. 4). By doing this, the access frequency of files within the same group, which are relatively close to each other, can be determined at a glance, so that new information sources can be discovered, and even beginners can follow the hierarchical structure depending on the access frequency in the group. Therefore, the target information can be easily accessed. Here, the total access frequency of all members of the group to which the user belongs is listed on the right side of the asterisk (*). However, other display forms may be adopted.
[0049]
Further, as shown in FIG. 6, the determination process of the group to which the user belongs is activated by external input (manual system input in advance) or by accumulating access frequency vectors (step S600). If the access frequency vector is stored in the group table storage unit 14, the group to which the user belongs is calculated from the stored vector (step S601). That is, the access frequency vector can be automatically specified according to the result of clustering.
[0050]
In this way, the group determination process is performed to generate and correct the group table (step S602). Based on the appropriate group determination result, as shown in FIG. The access frequency of other users can be correctly visualized.
[0051]
(Embodiment 2)
FIG. 7 is a diagram showing a hierarchical structure in which two types of personal views shown in FIGS. 3 and 4 are simultaneously provided and supported when shared information is managed in a folder tree in the second embodiment. The configuration of the information presentation apparatus of the second embodiment is the same as that of FIG. 1 of the first embodiment. However, when the personal view is generated (step S503 in FIG. 5), two types of personal views are displayed. It is characterized in that it is generated and added to the original hierarchical structure.
[0052]
In the second embodiment, as shown in FIG. 7, since the hierarchical structure is multi-layered and the hierarchy is deep, it is necessary to follow a number of unrelated folders along the way to the target folder. Since it cannot be obtained (it needs to be clicked about 8 times), it is possible to trace the target file most efficiently according to the situation by providing the user with two types of personal views.
[0053]
For example, in the hierarchical structure display field 72 of FIG. 7 in the second embodiment, two types of personal views are provided: a personal view that changes the hierarchical structure (FIG. 3) and a personal view that does not change (FIG. 4). Yes. In the personal view 32 for changing the hierarchy, the most frequently accessed hierarchy (★ 7, ★ 5, etc.) that the user accesses most frequently is brought up to the top hierarchy separately from the original hierarchical structure 31 and displayed together. Yes. For this reason, since the user only needs to select the personal view 32, the number of levels to be selected is small (one click), and the user can easily reach the target folder.
[0054]
In addition, the personal views 74 and 75 that are not changed are displayed by adding their own (or the same group) access frequency to the corresponding part of the original hierarchical structure 31 by adding a number with ★. Here, the access frequency of the same group member as the user is also displayed (numbers with ☆ in the figure). Thus, by relying on the access frequency display added to the original hierarchical structure 31, it is possible to trace the target folder without hesitation, and to promote discovery of a new information source.
[0055]
As described above, according to the first and second embodiments, since the statistics of the access frequency from the user for each layer are taken and the personal view showing the access status for each user is generated, It is possible to realize.
[0056]
Further, according to the first and second embodiments, at least the frequently accessed hierarchy accessed by the person is extracted from the original hierarchical structure, and is displayed as a personal view. You can quickly reach the target hierarchy without following it.
[0057]
Further, according to the first and second embodiments, since the personal view with the access frequency added in the vicinity of the individual hierarchies of the original hierarchical structure is provided, the location of the target information at the location is relied on the personal view. And the user can efficiently trace using the original hierarchical structure.
[0058]
In addition, according to the first and second embodiments, not only the personal view of the user, but also the personal view of other users belonging to the same group as the user is provided, and thus cannot be obtained only by the personal view of the user. Discovery of new information sources can be promoted, and support can be provided so that even a beginner can efficiently follow the hierarchical structure.
[0059]
In the above embodiment, the description mainly focused on the examples related to the folder tree. However, the hierarchical structure using hyperlinks can be considered in the same manner, and a suitable effect can be obtained as in the above examples. it can.
[0060]
