The registration search information acquisition unit 13 acquires registration search information corresponding to the user identification information received by the reception unit 3.
[0025]
The similar registration search information acquisition means 15 calculates the similarity based on the feature information of the registration search information acquired by the registration search information acquisition means 13 and the feature information of other registration search information, and the similarity is a predetermined value. If the value is equal to or greater than the value, the other registration information is acquired as similar registration search information information.
[0026]
The search information generation unit 17 includes interest information of the registered search information acquired by the registration search information acquisition unit 13, interest information of the similar registration search information acquired by the similar registration search information acquisition unit 15, and user search information acquired by the reception unit. Based on the above, search information is generated. The transmission unit 19 transmits the search information generated by the search information generation unit 17 to the search server 5. The registered search information updating means 21 generates new interest information based on the search result information received by the receiving means 19 and the interest information of the registered search information acquired by the registered search information acquiring means 13, and the interest of the registered search information. The information is updated to the generated new registration search information, and the updated registration search information is recorded in the storage unit 23.
[0027]
Thereby, a search can be performed based on user search information and similar registration search information. That is, since the search can be performed in a form that reinforces the user search information, information that accurately answers the information that the user desires can be provided.

[0050]
An example of feature information is shown in FIG. 11, and an example of interest information is shown in FIG.
[0051]
5. Flowchart of search information generation program
The general flow of the search information generation program recorded in the HD will be described based on the flowchart shown in FIG.
[0052]
  The flow of the information search program is as follows: 1. User authentication for a user connected to the search device (S701), 2. Acquisition of characteristic information about the user whose connection authentication is obtained from the HD (S703), 3. User search information of the user 4. Acquisition via the Internet (S705), 4. Generation of search information based on the feature information acquired from the HD and user search information acquired from the Internet (S707), 5. Generated search informationofTransmission to a predetermined search server (S709), 6. Receiving search result information from the search server for the transmitted search information (S711), 7. Transmission of search result information to the same user (S713), and 8. Receiving The interest information regarding the user based on the search result information is updated (S715). Hereinafter, each process will be described in detail.
[0053]
5.1 User authentication (Fig. 7: S701)
When the CPU 41 determines that a user (hereinafter referred to as a search user) has accessed a site providing this service, the CPU 41 transmits a login screen to the search user (S801). An example of a login screen transmitted to the search user at this time is shown in FIG.
[0054]
On the login screen, a user ID input box B801 for inputting a user ID, a password box B803 for inputting a password, a confirmation for transmitting the information input in the user ID input box B801 and the password input box B803 to the search information generating device Cancel button B807 for canceling information entered in button B805, user ID input box B801 and password input box B803 and returning to the default state, and new registration for requesting new registration of user to search information generating device Button B809 is displayed.
[0055]
When a search user who has already been registered as a user in the search information generating apparatus is authenticated, the user ID and password given to him / herself are entered into the corresponding boxes and the confirmation button B805 is selected. As a result, the confirmation signal, the user ID, and the password are transmitted to the search information generating device.
[0056]
When receiving the confirmation signal (S803), the CPU 41 of the search information generating device performs user authentication processing based on the received user ID and password (S805). The user authentication process is the same as that generally performed, and a detailed description thereof is omitted here.
[0057]
On the other hand, a search user who has not completed user registration may select the new registration button B809. As a result, a new registration signal is transmitted from the search terminal 23 to the search information generation device 21.
[0058]
When receiving a new registration signal (S807), the CPU 41 performs a new user registration process. This user registration process is performed by the same process as the feature information registration process for an existing registered user, which will be described later.
[0059]
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).
[0060]
Here, an example of the feature information recorded in the HDD 43 is shown in FIG. For the constituent elements of the characteristic information shown in FIG. 5, job type: software, job title: chief, age: 36, etc. are recorded for user A. In this case, assuming that the search user is A, an example of the feature information confirmation screen transmitted to the search user A is shown in FIG.
[0061]
The feature information confirmation screen has an attribute information input area A101 for displaying attribute information relating to a previously registered search user, and a search policy input area A103 for inputting previously registered search policy information. In addition, when there is no mistake in the displayed attribute information and search policy information, or there is no change, the confirmation button B101 selected by the user, and the user selects when the contents of the displayed attribute information and search policy information are changed. A change button B103 is provided.
[0062]
FIG. 12 shows a feature information confirmation screen related 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 according to the feature information shown in FIG. Further, “XXX” is displayed in the policy input box B109 regarding the search server.
[0063]
If the displayed contents are correct, the search user selects the confirmation button B101. As a result, a confirmation signal is transmitted to the search information generating device 21.
[0064]
When receiving the confirmation signal (S103), the CPU 41 performs a process of acquiring search information (hereinafter referred to as user search information) from the search user. The process for acquiring user search information will be described in the next section.
[0065]
  On the other hand, the feature information displayed on the feature information confirmation screen is incorrect.IaiaIf the registered user wants to change the registered content, the search user selects the input box of the corresponding item and then changes the content. Then, the update button B103 is selected.
[0066]
When the CPU 41 receives an update signal indicating that the update button B103 has been selected (S105), the CPU 41 acquires the updated feature information and updates the feature information corresponding to the search user recorded in the HDD 43 ( S107).
[0067]
Even when a new registration command is received in step S803 (see FIG. 8), the CPU 41 transmits the feature information input screen shown in FIG. In this case, each input box is blank. The search user inputs information into each blank box and then selects the confirmation button B101.
[0068]
When receiving a confirmation signal in the new user registration, the CPU 41 registers the feature information corresponding to the search user in the HDD 43.
[0069]
5.3 Acquisition of search information (Fig. 7: S705)
When the acquisition of the feature information is completed, the CPU 41 transmits a user search information input screen (S131). Here, FIG. 14 shows an example of a user search information input screen. The user search information input screen has a search information input box B141 and a search button B143. The search user inputs the content to be searched into the search information input box B141. In FIG. 14, “I want to know about the latest personal computer trends” is entered in the search information input box B141. In this embodiment, search information can be input in natural language.
[0070]
When the search user finishes inputting in the search information input box B141 and wants to search the user search information, the search user may select the search button B143. Thereby, the search information is transmitted from the search terminal to the search information generating device 21.
[0071]
Upon receiving the user search information (S133), the CPU 41 performs search information generation processing.
[0072]
5.4 Generation of search information (Fig. 7: S707)
The search information generation processing will be described based on the flowchart related to search information generation 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.
[0073]
(1) Self-search correlation value
When the user search information is received, the interest information of the search user registered in the HDD 43 is acquired (S151). Then, a correlation value between search information and interest information (hereinafter referred to as a self-search correlation value) is calculated (S153). The space vector method is used to calculate the correlation value.
[0074]
For example, it is assumed that the search user A transmits user search information “I want to know the latest personal computer trends” as shown in FIG. It is assumed that the interest information of the search user A is recorded in the HDD 43 as shown in FIG.
[0075]
As for Search User A, “Let's establish a strong and highly profitable business and actively implement new business fields and promote management quality improvement activities to realize management reform.” , It contains a lot of problems, one is the problem of the estimate.
[0076]
A self-search correlation value between each interest information and user search information is calculated using a space vector method. In this case, since there is not much correlation between the user search information and the interest information, the self-search correlation value is low.
[0077]
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). That is, not only the user search information input for the search by the user but also information similar to the current user search information from among the interest information registered in the HDD 43 is used. Thus, by using not only the user search information but also the interest information, the information necessary for the search can be increased, so that the user can obtain the information he wants more reliably.
[0078]
On the other hand, when the self-search correlation value is smaller than the predetermined value, the search user's interest information is not used for the search.
[0079]
(2) Attribute correlation value
If the self-search correlation value is smaller than the predetermined value, attribute information about the search user is acquired from the HDD 43 (S1601). Further, the attribute information of other users recorded in the HDD 43 is acquired (S1603). Then, a correlation value (hereinafter referred to as an attribute correlation value) between the acquired attribute information of the search user and another user is calculated (S1605).
[0080]
In the present embodiment, the attribute correlation value is calculated as follows. There are a plurality of attributes, which are constituent elements of the attribute information, such as job type, title, age, gender, address, hobby, etc. (see FIGS. 5 and 11). The search user can designate which attribute correlation value is to be calculated based on the content to be searched. That is, the search user himself can weight each attribute.
[0081]
For example, when searching for information on hobbies, weighting is performed for each attribute such as job type: 0, job title: 0, age: 3, gender: 5, address: 0, hobby: 10.
In addition, the full score of the score given as a weight is 10 points. In this way, the search user himself / herself weights the attribute, thereby obtaining information intended by the search user.
[0082]
(3) Self-other search correlation value
If the attribute correlation value is greater than or equal to a predetermined value (S1607), the interest information of the user (hereinafter referred to as correlation user) is acquired (S1609). A correlation value between the acquired correlation user interest information and the search user (hereinafter referred to as self-other search correlation value) is calculated in the same manner as the calculation of the self-search correlation value (S1611). If the calculated self-other search correlation value is greater than a 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).
[0083]
For example, when the interest information shown in FIG. 17 is registered, the search user is A, and the self-other correlation value is calculated for the other registered users B, C,. Further, if the user search information of 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 “Development code name“ Millennium ”of registered user C is“ "Windows Me" seems to have been decided "is calculated on the assumption that the self-other correlation value is high. Therefore, the user search information of search user A “I want to know the latest personal computer trends” and the interest information of registered user C “The name of the successor OS of Windows 98 known by the development code name“ Millennium ”is decided as“ Windows Me ”. The search information is generated. In the present embodiment, both pieces of information are used as search information as they are.
[0084]
  Such a self-other search correlation value is calculated for all users registered in the HDD 43.Whether or not(S1617), and if the determination for all users is completed, the generated search information is transmitted.
[0085]
5.5 Sending search information (Fig. 7: S709)
It is determined whether or not the above-described self-other search correlation value calculation has been performed for all users registered in the HDD 43 (S1617: see FIG. 16). Based on the “search server” registered in the search policy information regarding the search user, the information is transmitted to each search server.
[0086]
When transmitting the search information, the search information is processed according to the search conditions of each search server. For example, when 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 performs a search by keyword search, it extracts a keyword from the generated search information and transmits it to the search server.
[0087]
5.6 Updating interest information (Fig. 7: S715)
When search result information is received from each search server for the transmitted search information (hereinafter referred to as server search result information), search result information is generated based on the received server search result information.
[0088]
The server search information generally indicates the URL of the searched information. Therefore, information is collected based on the URL. When collecting the information, the CPU 41 acquires search policy information related to the search user recorded in the HDD 43 (S1801). Based on the acquired search policy information, a filtering process is performed (S1803).
[0089]
For example, when a paper or newspaper is registered as a search target of the search policy information, only information corresponding to the paper or newspaper is collected. Similarly, filtering processing is performed on the collected information for other search policy information.
[0090]
A transmission format change process is performed on the information collected in this way (S1805). Then, the search result information after the format change is transmitted to the search user (S713: see FIG. 7). When transmitting search information to a search user, the search information transmission format is arranged with reference to search result, output result, and output result sending means, which are constituent elements of search policy information.
[0091]
For example, if there is search result: summary, output result: HTML, output result sending means: mail, the contents of the search result information are summarized and sent to the search user in the HTML format by e-mail. An example when the search result information is transmitted to the search user by electronic mail is shown.
[0092]
Returning to FIG. 18, the interest information of the search user is updated based on the information acquired based on the server search information (S1807). At this time, the interest information is updated while referring to the search policy information related to 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 larger than the predetermined value (S1809), the old interest information with the registered date and time is deleted (S1811).
[0093]
[Other Embodiments]
In the above-described embodiment, the number of search servers is one, but the search information may be transmitted to a plurality of search servers.
[0094]
  In the above-described embodiment, it is natural that the search user inputs search information.wordHowever, it is also possible to enter a keyword. Moreover, you may enable it to input both a natural language and a keyword.
[0095]
  Further, in the above-described embodiment, the search user himself performs weighting.Umo andHowever, the search information generation device may perform weighting. For example, the search information generation device extracts keywords from the search information input by the search user, calculates the correlation value between the extracted keyword and each attribute,DoYou may do it. In calculating a correlation value between a keyword and an attribute, a space vector method or the like is used.
[0096]
Further, in the above-described embodiment, the self-other search correlation value is calculated for all users registered in the HDD 43. However, the self-other search correlation value may be calculated only for a certain range of users. Good. As a certain range, there are methods such as determining a range based on similar job types while paying attention to the job type of attribute information, determining a range focusing on age, and determining according to gender.
[0097]
  Similarly to the calculation of the attribute correlation value, the search user may weight each attribute of the attribute information when calculating the self-other search correlation value. Furthermore, in the above-described embodiment, the old interest information with the registered date and time is deleted, but the correlation value between the interest information is calculated and deleted from the one with the lower correlation value.EvenGood. In calculating the correlation value, a space vector method or the like is used.
[0098]
Furthermore, 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 used as search information as they are. However, instead of using each other's information as it is as search information, some processing may be added to generate one search information.
[0099]
For example, when the interest information shown in FIG. 17 is registered, the search user is A, and the self-other correlation value is calculated for the other registered users B, C,. Further, if the user search information of 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 “Development code name“ Millennium ”of registered user C is“ "Windows Me" seems to have been decided "is calculated as having a high self-other correlation value. Therefore, the user search information of search user A “I want to know the latest personal computer trends” and the interest information of registered user C “The name of the successor OS of Windows 98 known by the development code name“ Millennium ”is decided as“ Windows Me ”. The search information is generated. In the present embodiment, both pieces of information are used as search information as they are.
[0100]
  Furthermore, in the above-described embodiment, the search user can select the search server by the “search server” in the search policy information. However, the search server may not be selected. That is, you may make it search about all the search servers which exist on the internet. further,Search information generationIn the device 21, a search server may be set in advance, and the search may be performed on the search server.
