The update notification server 32 is the WWW browser 1
When a search information registration request is received from No. 1, the search information is registered in the search information database 35.

The update notification server 32 transmits an update notification to the user's mail receiving environment 12 according to the notification schedule specified in the search information, and schedules the next notification time. At this time, if the next notification time exceeds the registration time limit, the search information is deleted from the search information database 35.

The update notification mail periodically notified from the update notification server 32 includes new and updated WWWs.
The page information, the extension URL, and the deletion URL are included.

The extension URL is a URL for extending the registration period of the update information.

The deletion URL is a URL for deleting update information.

When the registration ID is "N", the extension URL
Is, for example, http://www.search.com/expand.cgi?id=N
And the deleted URL is, for example, http://www.search.co.
m / delete.cgi? id = N The CGI is a common gateway interface, and is an interface used by a WWW server for transmitting and receiving information to and from a back-end program (gateway).

When the extension URL is accessed, the update notification server 32 extends the registration term of the designated registration ID. The extension period includes, for example, a method in which the registration period is the same as the first registration period, and a method in which a WWW page for specifying the registration period is transmitted and the user selects the next registration period.

The registration server 33 is, for example, a PC server,
It is a WWW server configured with a UNIX server or the like.
The registration server 33 acquires page information from the automatic collection robot 37, the WWW browser 21, and the WWW server 22, registers a new or updated WWW page in the full-text database 34, and transmits the page information to the update notification server 32.

For example, there is a method that performs it periodically once a day,
A method of changing the collection interval based on the update frequency of each W page may be used.

The provider of the search service environment 30 records the search conditions of the search server 31 and the search information database 3
Based on the search condition, notification deadline, and the like registered in 5, the user can provide statistical information such as a keyword required by a user of the search service and a keyword of interest.

The keyword searched at a certain time from the record of the search condition of the search server 31 can be obtained from the registered contents of the search information database 35.

In the search information database 35, the date of birth,
By registering information such as gender, blood type and hobby,
For example, statistics of a keyword of interest for each age group can be provided.

Next, the operation of one embodiment of the present invention will be described in detail with reference to FIGS. FIG. 2 shows the WW
FIG. 3 shows an example of a search screen on the W server 11, and FIG. 3 shows an example of a search result. FIG. 3 to FIG. 7 are flowcharts showing the processing of one embodiment of the present invention.

Referring to FIG. 4, the user of the search service accesses the search server 31 of the search service environment 30 via the WWW browser 11 of the user environment 10 (step A1).

In response, the search server 31 transmits a search screen (step A2).

A search screen as shown in FIG. 2 is displayed on the WWW browser 11 (step A3).

The user inputs a search condition in the search condition column displayed on the screen of the WWW browser 11, and clicks "start search".
When the button is clicked with the mouse, the WWW browser 11
Transmits the search condition to the search server 31 (step A).
4).

When receiving the search condition, the search server 31 searches the full-text database 34 for page information corresponding to the search condition (step A5). As a search condition,
For example, if "A4", "notebook PC", and "new product" are input by separating them with a blank space, "A4", "notebook PC"
Is searched for a page in which all of "new products" are described. The search may be performed by only one device, or may be performed by a plurality of devices in parallel. For example, there is a method in which the full-text database 34 is divided into several parts, a plurality of devices perform parallel searches, and search results are collected in the search server 31.

The search server 31 transmits the search condition and the search screen to which the search result is added to the WWW browser 11 (step A6).

The search result as shown in FIG. 3 is displayed on the WWW browser 11 (step A7).

In the example of FIG. 3, "A4" is used as a search condition.
"Note PC" and "new product" are specified, and as a result, 120 WWW pages correspond to the search condition, and the first to tenth pages are displayed.

When the link of "display next 10 cases" is clicked, eleventh to twentieth cases are displayed.

The search result displays, for example, the title, update date, URL, the first few characters of the WWW page, etc., of the WWW page corresponding to the search condition. Clicking on the title of the WWW page jumps to the WWW page. it can.

The user can change the character string in the search condition column in FIG. 3 and click the search start button to perform the search again.

The user selects a notification destination mail address, a notification schedule, and a registration deadline on the screen shown in FIG.
When the “register” button is clicked on with a mouse, WWW browser 11 sends a search information registration request to update notification server 32.
(Step B1).

The search information registration request includes search conditions, notification destination distinction, notification destination mail address, and notification destination schedule.

Upon receiving the search information registration request, the update notification server 32 stores the search information registration request in a temporary file, issues a registration ID for uniquely identifying the search information, and performs registration for validating the registration. The URL is transmitted to the mail receiving environment 12 by mail (step B2).

If the registration ID is “N”, the registration URL
Is, for example, http://www.search.com/validate.cgi?id=
N.

The method for validating the registration is sent in the form of a URL by using a mail tool having a “clickable URL function” (the URL can be referred to by clicking the URL on the mail tool). This is because the update notification server 32 can be efficiently accessed by clicking with the mouse or specifying the registration URL in the WWW browser 11.

[0086] The user can use the WWW browser 11
When accessing the registration URL (step B3), the update notification server 32 registers the search information registration request stored in the temporary file in the search information database 35 (step B4).

When the registration in the search information database 35 is completed, the update notification server 32 transmits a message indicating that the registration is completed to the WWW browser 11 (step B5).

As described above, the registration URL is transmitted to the search user by e-mail without immediately performing the registration.
This is to prevent the notification mail from being transmitted by mistake in the notification destination mail address, or to prevent the notification mail from becoming unsolicited mail by intentionally specifying the mail address of another person.

The update notification server 32 deletes the search information registration request that has not been validated and remains stored in the temporary file after a certain period of time.

Next, referring to FIG. 5, the automatic collection robot 37 determines the automatic collection destination based on the page stored in the full-text database 34 and the hyperlink included in the page, and acquires the page information. (Step C
1) The operation of transmitting the page information to the registration server 33 (step C2) is periodically repeated.

Upon receiving the page information, the registration server 33 compares it with the contents of the full-text database 34 (step C3).

The received page information is the full-text database 3
If the content matches the content stored in No. 4, the received page information is discarded and the process ends.

The received page information is the full-text database 3
If the content does not match the content stored in No. 4, the registration server 33 transmits the received page information to the update notification server 32 (Step C4), and registers the page information in the full-text database 34 (Step C5).

The update notification server 32 checks whether the received page information satisfies the search condition for all search information registered in the search information database 35 (step C6) (step C7).

In the update notification server 32, when the received page information satisfies the search condition (step C8),
The update information is stored in the update notification database 36 (step C9).

Next, referring to FIG. 6, the information provider
The user accesses the registration server 33 of the search service environment 30 via the WWW browser 21 of the information provider environment 20 (step D1).

In response to this, the registration server 33 transmits a screen for inputting the URL of the update page specified by the information provider (step D2).

The WWW browser 21 displays a field for inputting the URL of the WWW page and a "Send" button (step D3).

The URL of the page updated in the URL input field
Enter L and click the "Send" button with the mouse.
The WWW browser 21 transmits the URL of the updated page to the registration server 33 (Step D4).

The registration server 33 acquires the page information of the received URL (step D5).

The subsequent operation (steps D6 to D12) is the same as the operation when receiving page information from the automatic collection robot 37 (steps C3 to C9).

Next, referring to FIG. 7, the WWW server 2
When a new or updated page is detected from the pages provided by its own server, the URL is registered on the registration server 3.
3 (step E1).

When the registration server 33 receives the URL from the WWW server 22, the registration server 33 accesses the WWW server 22 to acquire the page information of the URL (step E).
2).

The subsequent operations (steps E3 to E9) are the same as the operations performed when the page information is received from the automatic collection robot 37 (steps C3 to C9).

Next, a second embodiment of the present invention will be described. In the second embodiment of the present invention, the update notification server 32 uses the WWW browser 11 to send the update notification server 3 without sending the update information to the mail reception environment 12.
The second embodiment differs from the first embodiment in that the second embodiment refers to the update information.

Next, the operation of the second embodiment of the present invention will be described. FIG. 8 is a flowchart showing the operation of the second embodiment of the present invention.

Referring to FIG. 8, the WWW browser 11 performs a search on the search server 31 until the search result is displayed on the screen (from step A1 to step A).
7) is the same as in the first embodiment.

In FIG. 3, if only the registration term is selected without inputting the notification mail address and the notification schedule, and the “Registration” button is clicked with the mouse, the WWW browser 11 sends the search condition, The registration deadline is transmitted to the update notification server 32 (step B1).

When receiving the search information registration request, the update notification server 32 issues a registration ID and registers the search information in the search information database 35 (step B2).

The update notification server 32 transmits to the WWW browser 11 a message including the completion of the registration, a reference URL for referring to the registered contents, and a deletion URL for deleting the registered contents (step B3). .

[0093] The WWW browser 11 displays the registration completion, the reference URL, and the deletion URL. Reference URL is registration I
URL including D. For example, when the registration ID is “N”, the URL is http://www.search.com/refer.cgi?id=N.

The deletion URL is a URL including the registration ID. For example, when the registration ID is “N”, http: // w
ww.search.com/delete.cgi?id=N

The search user refers to the update information using the reference URL without receiving the notification from the update notification server 32.

As described above, in this embodiment, the user environment 1
The mail receiving environment 12 of 0 is unnecessary, and the user can know the page update by actively referring to the stored update information.

Next, a third embodiment of the present invention will be described. A third embodiment of the present invention relates to a WWW in an information provider environment.
The difference from the first embodiment is that the server provides limited information without targeting servers all over the world.

For example, the collection target of the automatic collection robot 37 is limited to pages of performance information, price information, stock information, and the like of the processor maker. In addition, by providing search conditions in addition to free words and phrases and displaying frequently used keywords such as performance information, price information, stock information, and the like in advance and making them selectable, a service for guiding the latest information of each processor maker is provided. Function can be realized.

This embodiment is implemented as a business model in which a value-added service of providing the user with the latest information is provided to the user, and the user pays the usage fee.
