JP 2001-290729 A

  However, even if the same home page is uploaded, it varies from one that is rarely updated thereafter to one that is relatively well updated. Therefore, if you try to see new content, you must check both what has been updated and what has not been updated. In addition, only a part has been updated in the confirmation, and in order to see some new pages, all other homepages that have not been updated must also be checked for updates. It is a waste of work.

  In addition, if the user wants to find a new updated home page quickly, the above confirmation search must be frequently performed, which is also troublesome.

  Even if an updated homepage can be found, it is often found that a few days have passed since it was updated, and it cannot be said that it is immediately viewed as soon as it is updated.

  Therefore, the object of the present invention is to search for the page (the Web data) on which the article being searched is found in the home page selected by the user, and the Web data searched in this way. Is updated later, the updated web data is also searched for, and a series of such cycles can be performed at a predetermined opportunity, or a homepage monitoring system capable of notifying the updated contents Is to provide.

  For the above purpose, the present invention provides a homepage monitoring system using an Internet client computer and a search proxy server computer.

First, in the invention according to claim 1,
(A) An input means for inputting request data including a desired keyword suitable for a theme to be searched and a homepage address to be searched, and the client transmits the input request data to the search proxy server. And transmitting means.

  (B) Further, the server is the search proxy server having a search result database for storing Web data searched from a Web server on the Internet. The search proxy server includes a receiving unit that receives the request data transmitted from the client, an acquisition unit that acquires the homepage of the address and a Web data of a page having a predetermined association with the homepage, and the acquired Extracting means for extracting Web data including the keyword from Web data, and detecting new Web data not included in the search result database as update data from the Web data extracted by the extracting means. It has a detection means and an update means for updating the detection result database with the detected update data.

  In general, the “homepage” may mean the top page opened by the homepage URL, or may include all subordinate pages that can be moved from there, but here it means the top page. Here, the Web data is usually data displayed on the client screen. In other words, on the homepage screen displayed on the client, several destinations to move to other screens are displayed, and clicking on the destination with the cursor will display the new screen. . However, in the present invention, instead of sending such Web data such as a home page to the client for display, Web data containing a desired keyword is extracted from the Web data in the search proxy server. To do. This extraction is performed by extraction means, for example, by matching character strings.

  The Web data extracted in this way is checked to see if it is already stored in the search result database. If it is not stored, the search result database is updated using this Web data as update data. It is. This update data page may be a new page or an update page of an existing page. In the case of a new page, it is updated by new writing. In the case of an update page, since the Web data corresponding to this is already stored in the search result database, the old Web data of this existing page is updated. Alternatively, there is a method of saving the data of the old page as it is and adding an update page to the old page. Since the search result database is initially in an empty state, all the update data is newly written as a new page at first. Then, the subsequent Web data determines whether it is a new page or an updated page.

  As described above, in this homepage monitoring system, if the client inputs the desired keyword suitable for the theme that the user of this system wants to search and the address of the homepage that the user wishes to search using this keyword, it can be accessed from the Internet. Web data including the keyword can be obtained. That is, the search proxy server searches the homepage of the URL from various web servers on the Internet, and extracts web data including the keyword from the homepage and web data having a predetermined association with the homepage. is there. As a result, the user of this system can obtain information on the Internet regarding the theme that he / she wants to know. The information obtained in this way is ultimately provided to the client user, but how it is notified may vary. For example, there is a method of notifying by e-mail or creating an inquiry homepage of the system on the search proxy server side and displaying the result so that it can be viewed at any time.

  In addition, from the home page that the user desires to search, it is possible to search even page Web data having a predetermined association with this home page. In the invention according to claim 2, this “predetermined association” is designated as hypertext. The association by. This facilitates acquisition of the associated page. Here, hypertext is a computer-based document system, which is a mechanism that allows multiple documents to be linked together by embedding location information (hyperlinks) of other documents in any location of the document. is there. As a result, it is possible to acquire other Web data linked from the first acquired home page, acquire other Web data from the acquired Web data, and repeat this process one after another for association. All the obtained Web data is acquired.

  Further, the invention described in claim 3 is characterized in that the acquisition means, the extraction means, the detection means, and the update means have a repeat means for repeatedly executing at a predetermined trigger. For example, when a predetermined time is reached every day at a predetermined time, acquisition of Web data is started with a URL received and held from the client, and subsequent extraction means, detection means, and update means are sequentially activated. Such as daily processing. As a result, the latest Web data regarding the keyword at that time can be obtained. In addition to such a predetermined opportunity, for example, in addition to daily, new information on the Internet can be obtained by repetitive means that are repeatedly executed every other day or weekly.

  In the invention according to claim 4, the status of the search is notified for each opportunity. That is, the search proxy server has notification means for notifying the client of the updated contents updated by the update means. The notifying means is characterized in that the repeating means is repeated with the notifying means added after the updating means. Thus, the search result is notified to the user every time the repetitive means is executed. For this reason, once a user has entered a keyword or the like, notifications are made for each opportunity, and new net information can be obtained constantly.

  The invention according to claim 5 is characterized in that a predetermined trigger is input from the client and included in the request data. As a result, this predetermined opportunity is input by the user from the client, and therefore an opportunity suitable for the purpose of the user can be set. As a result, it is possible to predict how frequently the theme, home, and page to be searched are updated, and to search for the latest information in a cycle that matches the predicted update frequency.

  According to the present invention as described above, it is possible to search for the Web data containing the article to be searched for in the home page selected by the user, and when the Web data searched in this way is subsequently updated. The updated latest Web data can also be searched, and a series of such cycles can be performed at a predetermined timing, or the update contents can be notified.

  Next, the present invention will be described with reference to the drawings. As shown in FIG. 1, this homepage monitoring system is a homepage monitoring system using a search proxy server 1 and an Internet client 2. The search proxy server 1 includes a member database 10, a request database 20, and a detection result database 30.

  (Client); The client 2 has an input means, a transmission means, and an electronic mail function. The input means can perform application registration input for applying for the use of this system, an input screen display for inputting a request for use by a registered member, and input processing from this screen.

  When a registered member requests an individual search, a keyword suitable for a theme to be searched, a homepage address to be searched for and a search opportunity can be input. In addition, after the request is input in this way, the requested home page can be deleted or a new home page added can be retransmitted as request data. It is also possible to change the trigger once entered. In addition to the request data input in this way, the transmission means transmits various types of data (for example, a member ID, a password, etc.) to the search proxy server.

  (Server); Further, the search proxy server has a member database 10, a request data database 20, and a search result database 30, as shown in FIG. Furthermore, it has a receiving means, an acquisition means, an extraction means, a detection means, an updating means, and a notification means, and has a repeating means for repeatedly performing these means. Then, when the member inputs from the client 2, the repetition by the repeating means is performed in a cycle of once a day, for example. The trigger may be triggered several times a day in addition to once a day, or may be designated as a day of the week, once a week, or every other hour.

  The detection result database 30 is a database that stores Web data when the search proxy server 1 searches for target Web data from the Web server 3 on the Internet. This detection result database 30 is. Each Web data can be called by the page address (URL) of the Web data.

  The member database 10 is for registering information on members who use the homepage monitoring system, and is registered through a registration application from a client. Further, the request database 20 stores request data from each member. As shown in FIG. 2, the keyword 21 requested to be searched by each member can be registered. A single member can register a plurality of keywords 21. Each keyword 21 can register a plurality of URLs 22 of websites to be searched with the keyword 21. The member 11, the keyword 21, and the URL 22 have a hierarchical structure straddling the member database 10 and the request database 20 as shown in FIG. 2.

  The receiving means receives the request data input from the client 2, and is transmitted by pressing a transmission button (not shown) displayed on the input screen of the client 2, and the transmitted data is It is received by the search proxy server 1 side. However, this receiving means receives not only this but also application data for member registration and other various data.

  The acquisition means accesses the home page based on the URL 22 of the request data received in this way, and acquires all the Web data associated with the hypertext from the home page. Specifically, first, the home page of the URL 22 received from the client 2 is acquired. Next, all the hyperlinks included in the web data of this home page obtained are searched, and the next web data is searched and obtained from this hyperlink. Once acquired, the hyperlink is searched for in the acquired Web data, and the Web data is acquired. In this way, Web data is acquired one after another.

  In addition, whenever Web data is acquired in this way, the extraction means, detection means, and update means described below are executed. That is, the Web data including the keyword 21 is extracted from the acquired Web data by the extraction unit, and then the detection unit determines whether the Web data extracted as including the keyword 21 is new Web data to be updated. Then, the detected new web data is updated by the updating means. Web data that is not extracted or detected is discarded. The above processing may be performed as “extraction means → detection means → update means” every time one piece of Web data is earned. However, all the Web data is acquired first and acquired. All Web data may be processed by the extraction unit at a time, and the detection unit and the update unit may be processed at a time.

  The extraction means checks whether or not the acquired Web data includes the character string of the keyword 21, and if included, extracts this, and if it does not include the keyword 21, discards it as described above.

  The detection means compares the Web data extracted in this way with the detection result database to check whether the Web data is a new page. First, the detection result database is read with the page URL of the extracted Web data. The detection result database uses this URL as a read key.

  If there is no data of the corresponding URL in the database by this reading, the Web data becomes Web data of a new page, and this is used as update data.

  If data corresponding to the URL of the extracted Web data exists in the detection result database, it is Web data of an existing page. In this case, the extracted Web data is compared with the Web data read from the detection result database 30 to check whether they are the same. This is because both the web data are matched, and if they are the same, the page is an unupdated page, and the web data is discarded. If they are not the same, the page has been updated, and this Web data is used as update data. That is, the update data is a page including a keyword, and is Web data of a new page or an existing page that has been updated.

  The update means updates the update data as described above. Web data corresponding to the new page is written as new data in the detection result database. In addition, the Web data in which the existing page is updated will update the Web data in the detection result database. However, if the old data to be updated is also required, the old data may be written as new data without being updated. In this case, it is necessary to set the key of the written data as a URL and give another key associated with the old data in advance.

  Further, the notifying means describes the address of the page corresponding to the update data in the electronic mail message and transmits it to the client. As a result, a member who notices that the e-mail has arrived can open the e-mail and click the indicated URL to confirm the page.

  In the search proxy server, the cycle of the acquisition unit, the extraction unit, the detection unit, the update unit, and the notification unit as described above is repeatedly performed by the repetition unit. This repetition is repeated at a predetermined opportunity. For example, if the opportunity is entered as 9:00 am every day, this cycle starts at 9:00 am every morning, and new or updated pages created up to that point on the previous day You will be notified by email.

  Next, a method of using such a homepage monitoring system will be described with reference to FIG. First, a person who wants to use the service of this system applies for membership registration from the client 2 in advance ((1) in FIG. 3). Specifically, a registration application screen (not shown) is displayed on the client 2, a necessary application item is input from here, and a transmission button is pressed to transmit it to the search proxy server 1. With such an application, membership registration is completed and a member ID and password are issued ((2)).

  When a member who has made such a registration requests a search, an ID and password input screen is displayed. Then, after logging in to the homepage monitoring system, the keyword to be searched, the URL of the homepage, and the opportunity are entered from the request data input screen, and this is sent to the search proxy server as request data ((3)). . A plurality of URLs can be input.

  Upon receiving such request data, the search proxy server 1 side registers the request data in the request database 20 ((4)), and the detection result database 30 prepares to store the Web data searched by the keyword. (5).

  When such a preparation is made, the repetition means starts the repetition of the acquisition means and each subsequent means at a predetermined opportunity. In other words, the search proxy server has a clock, and the time and date can be known, but the repeater always uses this clock to see the date and time at which the acquisition unit and the subsequent units are started. (Id. (6)). Then, when an opportunity designated by the member comes, execution of these means is started ((7)). That is, the acquisition means for acquiring the Web data by the given URL is executed ((8)), and at that time, the extraction means extracts the Web data containing the keyword ((9)) and updates it. It is detected by the detecting means whether it corresponds to the data for use (same (10)), and if it corresponds to the update data, the detection result database is updated (same (11)). Then, an electronic mail in which a URL corresponding to the update data is written is created, and a notification mail is transmitted to the client ((12)).

  At the client, the fact that the e-mail has been received is displayed as a normal personal computer function, so that the member knows that there has been a notification. When the e-mail is opened, the URL of the updated update data page is described in the body of the e-mail. By clicking on the URL, the page can be confirmed.

  Note that notifications are not limited to e-mails. In the homepage of the homepage monitoring system itself, the fact that there is update data to be notified is displayed, and the members who see it are displayed in the homepage. You may make it see it from updated page URL.

  The present invention is not limited to the above-described embodiments, and may be implemented in any manner without departing from the spirit of the invention. Moreover, it is free to add various functions to the homepage monitoring system of the present application.

This figure shows the relationship between the search proxy server and the client on the Internet together with each database. This figure explains the member database and the request database. This figure is a diagram for explaining how to use the homepage monitoring system.
