Transmission of the generated search information to a predetermined search server (S709), 6. Search transmitted Receiving search result information from the search server for the information (S711);
7. Transmission of search result information to the same user (S71)
3) and 8. Update of interest information on the user based on the received search result information (S715). Hereinafter, each process will be described in detail.

5.1 User Authentication (FIG. 7: S701) The CPU 41 is a user (hereinafter referred to as a search user).
Determines that the user has accessed the site that provides the service, transmits a login screen to the search user (S801). FIG. 9 shows an example of a login screen transmitted to the search user at this time.

On the login screen, a user ID input box B801 for inputting a user ID, a password box B803 for inputting a password, a user ID input box B801, and a password input box B80
Confirm button B805 for transmitting the information input to No. 3 to the search information generating device, user ID input box B8
01 and a cancel button B807 for canceling the information input to the password input box B803 and returning to the default state, and a new registration button B809 for requesting a new registration of the user to the search information generating apparatus.
Is displayed.

When a search user who has already registered as a user in the search information generating apparatus is authenticated, he or she inputs the user ID and password given to the user into the corresponding boxes, and selects a confirmation button B805. I just need. Thereby, the confirmation signal, the user ID, and the password are transmitted to the search information generation device.

Upon receiving the confirmation signal (S803), the CPU 41 of the search information generation device performs a user authentication process based on the received user ID and password (S803).
805). Note that the user authentication process is the same as that generally performed, and a detailed description is omitted here.

On the other hand, a search user who has not completed user registration may select the new registration button B809. Thereby, a new registration signal is transmitted from the search terminal 23 to the search information generation device 21.

Upon receiving the new registration signal (S807), the CPU 41 performs a new user registration process. This user registration process is performed by a process similar to a process of registering characteristic information for an existing registered user described later.

5.2 Acquisition of Feature Information (FIG. 7: S703) When the user authentication is completed, the CPU 41 acquires feature information corresponding to the search user from the HDD 43. Then, a feature information confirmation screen including the acquired feature information is transmitted to the search user (S101).

FIG. 11 shows an example of the feature information recorded on the HDD 43. With respect to the constituent elements of the characteristic information shown in FIG. 5, the job type: software, post: chief, age: 36... In this case, if the search user is A, an example of the feature information confirmation screen transmitted to search user A is shown in FIG.

The feature information confirmation screen has an attribute information input area A101 for displaying attribute information on a previously registered search user, and a search policy input area A103 for inputting previously registered search policy information.

Change button B103 to be operated.

FIG. 12 shows a feature information confirmation screen relating to the search user A, so that 36 is displayed in the age input box B105 and software is displayed in the job type input box B107 in accordance with the feature information shown in FIG. Also, “XXX” is displayed in the input box B109 of the policy regarding the search server.

When there is no mistake in the displayed contents, the search user selects the confirmation button B101. Thereby, for the search information generation device 21,
A confirmation signal is sent.

When the CPU 41 receives the confirmation signal (S1)
03), a process of acquiring search information (hereinafter, referred to as user search information) from the search user is performed. The process of acquiring user search information will be described in the next section.

On the other hand, when there is an error in the feature information displayed on the feature information confirmation screen or when it is desired to change the registered content, the search user selects the input box of the corresponding item and then changes the content. And the update button B
Select 103.

When the CPU 41 receives an update signal indicating that the update button B103 has been selected (S105),
The updated feature information is obtained, and the feature information corresponding to the search user recorded in the HDD 43 is updated (S107).

Note that the CPU 41 also transmits the feature information input screen shown in FIG. 12 when a new registration command is received in step S803 (see FIG. 8). In this case, each input box is blank. Search users
After inputting information in each blank box, the confirmation button B101 is selected.

Upon receiving the confirmation signal in the new user registration, the CPU 41 registers the characteristic information corresponding to the search user in the HDD 43.

5.3 Acquisition of Search Information (FIG. 7: S705) When the acquisition of the characteristic information ends, the CPU 41 transmits a user search information input screen (S131). Here, FIG. 14 shows an example of the user search information input screen. The user search information input screen includes a search information input box B14.
1. It has a search button B143. The search user inputs the content to be searched in the search information input box B141. In FIG. 14, search information input box B
141, “I want to know the latest personal computer trends” is input. In the present embodiment, the search information can be input in a natural language.

The search user enters the search information input box B
When the input to the user 141 has been completed and the user wants to search for the user search information, he or she can select the search button B143. As a result, the search information generation device 2
The search information is transmitted to 1.

Upon receiving the user search information (S133), the CPU 41 performs search information generation processing.

5.4 Generation of Search Information (FIG. 7: S707) The search information generation processing will be described with reference to the flowcharts relating to the generation of the search information shown in FIGS. The search information generation process will be described separately for (1) self-search correlation value, (2) attribute correlation value, and (3) self-other search correlation value.

(1) Self Search Correlation Value When the user search information is received, interest information of the search user registered in the HDD 43 is obtained (S15).
1). Then, the correlation value between the search information and the interest information (hereinafter, referred to as
A self-search correlation value is calculated (S153). The calculation of the correlation value uses the space vector method.

For example, assume that search user A has transmitted user search information “I want to know about the latest personal computer trends” as shown in FIG. The HDD 43 has the configuration shown in FIG.
It is assumed that the interest information of the search user A is recorded as shown in FIG.

Regarding the search user A, “A strong high-profit business is established, and aggressive development of new business fields,
Realize management reform by promoting management quality improvement activities. "
And "The poor profit and loss of large projects is, in terms of content, so many problems.
Estimation problem. The rigor of estimation is still not enough. ''
Is registered.

The self-search correlation value between each piece of interest information and the user search information is calculated using the space vector method.
In this case, there is not much correlation between the user search information and the interest information, so the self search correlation value is low.

If the calculated self search correlation value is larger than a predetermined value (S155), search information is generated based on the user search information and the interest information (S157). In other words, not only the user search information input by the user for the search but also information similar to the current user search information among the self-interest information registered in the HDD 43 is used. In this way, not only user search information,
By using the information of interest, the information required for the search can be increased, so that the user can more reliably obtain the information desired by the user.

On the other hand, if the self search correlation value is smaller than the predetermined value, the interest information of the search user is not used for the search.

(2) Attribute Correlation Value If the self-search correlation value is smaller than a predetermined value, attribute information about the search user is acquired from the HDD 43 (S
1601). The attribute information of another user recorded in the HDD 43 is obtained (S1603). And
A correlation value between the acquired search user attribute information and another user (hereinafter, referred to as an attribute correlation value) is calculated (S160).
5).

In the case of the present embodiment, the calculation of the attribute correlation value is performed as follows. There are a plurality of attributes, which are constituent elements of the attribute information, such as occupation type, position, age, gender, address, hobbies, and the like (see FIGS. 5 and 11). The search user can specify which attribute to calculate the attribute correlation value based on the content to be searched. That is, the search user can weight each attribute.

For example, when it is desired to search for information relating to hobbies, each attribute is weighted such as job type: 0, post: 0, age: 3, gender: 5, address: 0, and hobby: 10. In addition, the perfect score for weighting is 10 points. As described above, the search user himself / herself weights the attribute, so that the information intended by the search user can be obtained more.

(3) Self-Other Search Correlation Value If the attribute correlation value is equal to or larger than a predetermined value (S1607), interest information of the user (hereinafter, referred to as a correlated user) is obtained (S1609). The correlation value between the acquired interest information of the correlated user and the search user (hereinafter referred to as the self-other search correlation value) is calculated in the same manner as the self-search correlation value calculation (S1611). If the calculated self-other search correlation value is larger than the predetermined value (S1613), search information is generated based on the interest information of the correlated user and the user search information of the search user (S1615).

For example, when the interest information shown in FIG. 17 is registered, the search user is A, and self-other correlation values are calculated for the other registered users B, C,. Further, if the user search information of the search user A is “I want to know the latest personal computer trends” shown in FIG. 14, the name of the successor OS of Windows 98 known as the development code name “Millennium” of the registered user C is “ It seems that Windows Me was decided. "
Therefore, the user search information of the search user A “I want to know the latest personal computer trends” and the interest information of the registered user C “Window code name“ Millennium ”
It seems that the name of the successor OS of s98 has been decided as "Windows Me". " In the present embodiment, both information are used as search information as they are.

The calculation of the self-other search correlation value is performed by the HDD.
It is determined whether or not the search has been performed for all the users registered in 43 (S1617). When the determination for all the users has been completed, a process of transmitting the generated search information is performed.

5.5 Transmission of Search Information (FIG. 7: S709) It is determined whether or not the calculation of the self-other search correlation value as described above has been performed for all the users registered in the HDD 43 (S1617: FIG. 7). 16), when the determination for all users is completed, the data is transmitted to each search server based on the “search server” registered in the search policy information on the search user.

When transmitting the search information, the search information is processed according to the search conditions of each search server. For example, if a natural language search is possible for a certain search server, the generated search information is transmitted as it is.
On the other hand, when a search server is performing a search by keyword search, it extracts a keyword from the generated search information and transmits the keyword to the search server.

5.6 Update of Interest Information (FIG. 7: S715) When search result information is received from each search server in response to the transmitted search information (hereinafter referred to as server search result information), based on the received server search result information, And generate search result information.

The server search information generally indicates the URL of the searched information. Therefore, information is collected based on the URL. When collecting information, the CPU
41 acquires the search policy information on the search user recorded in the HDD 43 (S1801). Then, a filtering process is performed based on the acquired search policy information (S1803).

For example, when a paper and a newspaper are registered as search targets of the search policy information, only information corresponding to the paper and the newspaper is collected. In the same manner, the filtering process for the information to be collected is performed for the other search policy information.

The information collected in this way is subjected to transmission format change processing (S1805). Then, the search result information after the format change is transmitted to the search user (S713: see FIG. 7). When transmitting the search information to the search user, the transmission format of the search information is arranged by referring to the search result, the output result, and the transmission means of the output result which are the components of the search policy information.

For example, search result: summary, output result: HT
Means for sending ML and output result: If there is a mail, the contents of the search result information are summarized and transmitted to the search user by e-mail in HTML format. An example of a case where search result information is transmitted to a search user by email is shown.

Returning to FIG. 18, the interest information of the search user is updated based on the information obtained based on the server search information (S1807). At this time, the interest information is updated with reference to the search policy information on the search user recorded in the HDD 43. At this time, the total data amount of the interest information is detected, and if it is equal to or more than a predetermined value (S18).
09), delete the interest information whose registration date is old (S1).
811).

[Other Embodiments] In the above embodiment, one search server is used. However, search information may be transmitted to a plurality of search servers.

In the above-described embodiment, the input of the search information by the search user is performed by natural input. However, a keyword may be input. In addition, both natural language and keywords may be input.

Further, in the above-described embodiment, the weighting is performed by the search user himself. However, the weighting may be performed by the search information generating apparatus. For example, the search information generation device may extract a keyword from search information input by a search user, calculate a correlation value between the extracted keyword and each attribute, and perform weighting. In calculating a correlation value between a keyword and an attribute, a space vector method or the like is used.

Further, in the above embodiment, the HD
Although the self-other search correlation value is calculated for all the users registered in D43, the self-other search correlation value may be calculated only for a certain range of users. As a certain range, there are a method of determining a range by a similar occupation by paying attention to the occupation of the attribute information, a method of determining a range by paying attention to an age, and a method of determining by gender.

Also, as in the case of calculating the attribute correlation value,
When calculating the self-other search correlation value, the search user may weight each attribute of the attribute information. Further, in the above-described embodiment, the interest information whose registration date and time is old is deleted. However, a correlation value between the pieces of interest information may be calculated, and the interest information may be deleted from the one having the lowest correlation value. In calculating the correlation value, a space vector method or the like is used.

Further, in the above-described embodiment, both the user search information of the search user and the interest information of the registered user having a high self-other correlation value are directly used as the search information. However, instead of using each other's information as it is, search processing may be performed to generate one piece of search information.

For example, when the interest information shown in FIG. 17 is registered, the search user is A, and self-other correlation values are calculated for the other registered users B, C,. Further, if the user search information of the search user A is “I want to know the latest personal computer trends” shown in FIG. 14, the name of the successor OS of Windows 98 known as the development code name “Millennium” of the registered user C is “ It seems that Windows Me was decided. "
Therefore, the user search information of the search user A “I want to know the latest personal computer trends” and the interest information of the registered user C “Window code name“ Millennium ”
It seems that the name of the successor OS of s98 has been decided as "Windows Me". " In the present embodiment, both information are used as search information as they are.

Further, in the above-described embodiment, the search user sets “search server” in the search policy information.
Thus, the search server can be selected, but the search server may not be selectable. That is, the search may be performed for all search servers existing on the Internet. Further, a search server may be set in advance in the inspection and extermination method generation device 21 and a search may be performed in the search server.
