Embodiments of the present invention will be described below with reference to the drawings. The embodiment of the classification information providing system according to the present invention is similar to that of FIG.
01, information retrieval device 102, information relay device 103, user client 104, computer networker 10
5.

The information 10, primary information 11, and secondary information 12 are the same as in the description of the prior art in FIG.

FIG. 1 is a block diagram showing in detail the configuration of the information retrieval device 102 and the information relay device 103 according to the embodiment of the present invention. In the information retrieval apparatus 102, FIG.
1, a secondary information storage unit 201, a secondary information collection unit 202, an information search unit 203, a Web server 204, an information classification unit 205, and an operation system unit 206 are provided.

An inter-information use history generation unit 304 for generating inter-information use history log data 21 from the information use history log data 20 accumulated in the information use history accumulation unit 302.
And an inter-information usage history transfer unit 305 for transferring the generated inter-information usage history log data 21 to the inter-information usage history receiving unit 207.

Similarly, in the information relay apparatus 103, Pr
An oxy server 301, an information use history storage unit 302, and an operating system unit 303 are provided. Also,
An inter-information use history receiving unit 207 that receives the inter-information use history log data 21 transferred from the inter-information use history transfer unit 305, divides the information into the respective pieces of secondary information 12 of the secondary information storage unit 201, and stores the information is newly added. Is provided.

The information use history accumulation unit 302 accumulates information use history log data 20 as shown in FIG. Also,
A plurality of secondary information 12 collected from the information storage device 101
Are stored in the secondary information storage unit 201 as shown in FIG.

FIG. 2 shows a sequence at the time of generating an inter-information use history according to the present embodiment. 2, in the information relay apparatus 103, the information use history generation unit 304 requests the information use history accumulation unit 302 for an information use history at an arbitrary timing, and acquires the accumulated information use history log data 20.

The inter-information use history generation unit 304 generates inter-information use history log data 21 based on the acquired information use history log data 20, and outputs the inter-information use history transfer unit 305.
Output to The inter-information use history transfer unit 305 transfers the inter-information use history log data 21 to the inter-information use history receiving unit 207. The inter-information use history receiving unit 207 accumulates the inter-information use history log data 21 as the inter-information data 13 in each of the secondary information 12 accumulated in the secondary information accumulation unit 201.

FIG. 3 shows an example of a method of generating the inter-information use history log data 21. The information use history generation unit 304 includes:
Regarding the information usage history log data 20 stored in the information usage history storage unit 302, two pieces of data having an appropriate information usage interval, in this example, "1/1 user 1 information" After the user uses information A based on "A" and "1/1 user 1 information B", it is calculated that information B has been used, and inter-information use history log data 21 is generated. The generated inter-information usage history log data 21 is transferred to the inter-information usage history receiving unit 207 by the inter-information usage history transfer unit 305.

Next, as shown in FIG. 4, from the inter-information usage history log data 21 received by the inter-information usage history receiving unit 207, data indicating which information has been used after the use of certain information is expressed as a secondary data. After each piece of information in each piece of secondary information 12 stored in the information storage unit 201 is used, the information is stored as inter-information data 13 indicating the usage frequency of how much other information was used.

Although the sequence at the time of information retrieval is performed in the same manner as in FIG. 10, in the case of the present embodiment, the inter-information data 13 representing the use frequency is used as the similarity between information, and this similarity is used. The secondary information 12 is classified based on the cluster analysis technique, and the classified information search result is output to the user client 104. As a result, the classification information output to the client in FIG. 10 is information in which the search result searched based on the secondary information is further classified based on the similarity described above.

In the present embodiment, the information storage device 10
1. Although the classification information providing system in which the information search device 102, the information relay device 103, and the user client 104 are separated has been described, the present invention is not limited to this.

As described above, in the present embodiment, the information use history log data 20 recorded along the time axis
Focusing on the behavior of a human user, the user uses information and generates information use history log data 21 describing which information is used next. The information is totaled for each information, and this is collected by the information search device 1
02 secondary information 12 stored in the secondary information storage unit 201
Is managed by the management unit (here, the inter-information use history receiving unit 207 and the secondary information storage unit 201) as the inter-information data 13, so that the similarity between the information is defined using the inter-information data 13 at the time of the information search. And that information obtained as a result of the information search can be classified based on a cluster analysis technique using the similarity.

Therefore, according to the present embodiment, it is possible to reflect the use situation between information obtained from the inter-information use history on the similarity between the information. Information can be classified according to the situation. Further, by managing the inter-information use history as a part of the secondary information 12 in the secondary information storage unit 201, only the secondary information storage unit 201 can be a search target at the time of information search. Speed can be prevented from decreasing.

Note that information retrieval may be performed by recording a program for realizing the function of the information retrieval apparatus 102 on a computer-readable recording medium and executing the program recorded on the recording medium. . In addition,
Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” is a floppy (registered trademark) disk, a magneto-optical disk, a ROM, a CD, or the like.
-A recording device such as a portable medium such as a ROM or a hard disk built in a computer system.

[0031]

As described above, according to the present invention,
By processing the information usage history, the information usage status is reflected at the time of information search, and it is possible to classify information having a high frequency of use among information into the same classification, and to classify heterogeneous information into another classification. This makes it easier to reach the information that the user wants to obtain, so that an efficient search can be performed.

In the case where the use frequency of two pieces of information is high, but there is no use history between the two pieces of information, it is possible to classify them into different categories. This is more effective because it can reflect the original usage status.

Also, since the classification changes depending on the time of use, information A and information B used to be the same classification before, but now information A and information C are classified into the same classification, and information C is classified into another classification. Dynamic and various classifications according to changes in the world's interests, such as belonging.

Furthermore, since the similarity of information has already been calculated at the time of information retrieval, it is possible to reduce the time required for classification.
