2. Description of the Related Art A general configuration of a conventional access tendency display system is shown in FIG. 2, the access trend display management device 200 includes an access index calculation device 201, an index storage device 202, a display format conversion device 203, and the like. The access index calculation device 201 inputs an access log, tallies the use status and the like for a certain period in the past as an access index, and stores it in the index storage device 202. The index storage device 202 stores an access index for each calculation target. The display format conversion device 203 includes the information request processing device 2
When there is a request from the user terminal 220 via the server 10, the requested access index is read from the index storage device 202, converted into a visually displayable format (visualization),
The information is sent to the user terminal 220 via the information request processing device 210.

As described above, according to the conventional technology, each access index is used independently, and even in response to a request from a user, the use status is simply displayed for each index independently. . In addition, the required index merely aggregates and displays the usage status in a certain period in the past. For this reason,
When the number of surveys was large, it was difficult to extract characteristic indices, and it was impossible to predict future usage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In addition,
The following embodiment is directed to a system for analyzing an access log of a WWW server. It is also assumed that two types of access indices are used, one obtained by simply calculating the number of accesses from the access log and one obtained by weighting.

FIG. 3 shows a configuration diagram of this embodiment. In FIG. 3, reference numeral 300 denotes an access tendency display management server;
Is a WWW server and 320 is a WWW client.
The access trend display management server 300 includes an access number calculation unit 301, a weighted access number calculation unit 302, a two-dimensional graph coordinate data creation unit 303, and a clustering analysis unit 3.
04, a database 305, and an HTML / VRML data output unit 306. The clustering analysis unit 3
04 is an option. Here, a configuration without the clustering analysis unit 304 is a first embodiment, and a configuration with the clustering analysis unit 304 is a second embodiment.

The number-of-accesses calculating unit 301 and the number-of-weighted-accesses calculating unit 302 of the access tendency display management server 300
Calculates an access count and a weighted access count for each access count measurement target (calculation target), for example, for each month, week, or day. The access log is input directly from the access tendency analysis target server or via the Internet or the like. The indexes (the number of accesses and the number of weighted accesses) calculated by the number-of-accesses calculation unit 301 and the weighted-number calculation unit 302 are
The two-dimensional graph coordinate data creation unit 303 represents the number of accesses to the X coordinate, the number of weighted accesses to the Y coordinate, and the URL of the file of the WWW server to be analyzed, which is a reference for calculating these indices, and the label. A set of coordinates including comment sentences and the like representing the contents of the file is created.
Thereafter, in the first embodiment, the set of coordinates is directly stored in the database 305. In the second embodiment, the clustering analysis unit 304 performs a statistical process on all or a part of the points plotted on the XY plane pasted by the X coordinate and the Y coordinate in the coordinate set, thereby performing the feature amount. Each set of coordinates having similar (trend) is grouped, and the result (cluster-ligent coordinate data) is stored in the database 304.

FIGS. 4 and 5 show processing flowcharts in the access tendency display management server 300 from the input of the access log to the storage of coordinate data or clustering coordinate data in the database 305. Here, FIG. 4 corresponds to the first embodiment, and FIG.
Corresponding to Note that the additional information of the log data is page name information, domain name information, and the like. FIG. 6 is a detailed flowchart of the two-dimensional graph coordinate data creation processing in FIG. 4, and FIG. 7 is a detailed flowchart of the clustering analysis processing in FIG.

A user requests necessary data from a WWW client 320, and the request is transmitted to a WWW server 31.
0, the access tendency display management server 30
Raised to zero. The HTML / VRML data conversion unit 306 of the access trend display management server 300 extracts appropriate data requested by the user from the database 305 and visualizes and displays a graph described in VRML or a WWW client described in HTML. The data is converted into a data format that can be interpreted by 320 and transmitted to the WWW client 320 via the WWW server 310.
FIG. 8 shows a processing flowchart when the user requests data.

FIG. 9 shows a specific example of display in this embodiment (embodiment 1). This is because the X-coordinate takes the number of accesses and the Y-coordinate takes the number of weighted accesses. In particular, the weighted number of accesses increases as the number of accesses becomes more recent at the analysis time, and the score decreases over time. This is an example using a degree function. The interest function is represented by, for example, C (t) = pN (t) + hC (t-1). Here, C (t) is the degree of interest, N (t) is the number of accesses, p is the number of accesses parameter, and h is the attenuation rate of interest. This is described in detail in Japanese Patent Application No. 8-331310 previously filed by the present applicant, and a description thereof is omitted here. On the other hand, the degree of interest is weighted so that the more recent the access is, the higher the score is.

In FIG. 9, the label of the number added to the plot point corresponds to the number of the category (file). For example, a file of the WWW server having a small numerical value of the X coordinate and a large numerical value of the Y coordinate like the label “2” has not been seen in the past, Since it can be said that the file has a particularly large number of accesses, it means that a further increase in the number of accesses is expected in the future. Conversely, the label "3
6 ", the value of the X coordinate is large,
Many WWW server files with small coordinate values have been seen in the past, but recently it can be said that the number of accesses is small, meaning that the number of accesses in the future is not expected. . As described above, by displaying the graph, characteristic data can be easily found visually, and it is possible to predict the future use situation.

FIG. 10 is a conceptual diagram of a display example of the second embodiment. That is, in the second embodiment, the results of grouping points plotted as shown in FIG. 9 for each set of coordinates having similar tendencies (features) are displayed. This is effective when files are classified according to their usage characteristics.

The embodiments of the present invention have been described above. Each processing procedure as shown in FIGS. 4 to 8 corresponds to a computer-readable recording medium such as a floppy disk or a memory card as an access tendency display program. It can be recorded on a compact disk (CD-ROM) and provided.

[0019]

As described above, according to the present invention, the following effects can be obtained. (1) By providing a predicted value of information usage,
It is possible to study the information provision method and management method. (2) Characteristic data can be found from a vast amount of data representing the usage status of information. (3) The usage status of the same information analyzed by a plurality of indices can be visually confirmed by a spatially represented graph.
