A terminal device 100 and a Web server 200 as an information providing system are connected to the Internet 300. The Web server 200 is configured to transmit display control information such as an HTML (Hyper Text Markup Language) file to the requested terminal device 100 based on a request from the terminal device 100. The terminal device 100 is configured to extract objects such as diagrams and tables from the display control information received from the Web server 200. Here, the Web server 200 may be connected to the Internet 300 in order for a third party different from the user of the terminal device 100 to provide content and the like. In the present embodiment, a plurality of Web servers 200 are connected to the Internet 300. These Web servers 200 have a general configuration including processing means, storage means, and communication means.

  FIG. 2 shows a configuration of a general PC (Personal Computer) as the terminal device 100 to which the object cutter program 110 of the present application is applied. For the bus 101, a keyboard 106 and a mouse 107 as input means, a display 108 as display means, a CPU 102 as processing means, a RAM 103 as a storage means, a ROM 104, an HDD 109 (Hard Disk Drive), and a NIC 105 as communication means. (Network Interface Card) is connected. I / F indicates an interface between the bus 101 and various devices. The HDD 109 stores an object cutter program 110, a standard object database 111, a Web page identifier extraction condition database 112, and the like. The CPU 102 of the terminal device 100 reads out the object cutter program 110 stored in the HDD 109 to the RAM 103 and executes it, thereby extracting an object from the display control information received from the Web server 200 with reference to the standard object database 111. Functions are provided. In addition, the CPU 102 of the terminal device 100 refers to the Web page identifier extraction condition database 112 and extracts the Web page identifier of the link destination Web page from the display control information received from the Web server 200.

  FIG. 3 shows the structure of the standard object database 111 stored in the HDD 109 of the terminal device 100. In this embodiment, the standard object database 111 stores an object start identifier and an object end identifier in advance in association with each other. Here, the object start end identifier is an identifier for identifying the start end of the object in the display control information. The object end identifier is an identifier for identifying the end of the object in the display control information. For example, an object in the table has “<table” as an object start identifier and “</ table>” as an object end identifier.

  FIG. 4 shows the structure of the Web page identifier extraction condition database 112 stored in the HDD 109 of the terminal device 100. In the present embodiment, the Web page identifier extraction condition database 112 stores in advance an object start identifier, an object end identifier, and an extractor identifier associated with a combination thereof. Here, the object start end identifier and the object end identifier are the same as those stored in the standard object database 111. The extraction unit identifier specifies a part to be extracted when extracting the Web page identifier of the link destination Web page from the object specified by the object start end identifier and the object end identifier. For example, when the object start identifier, the object identifier, and the extraction unit identifier are “<a”, “</ a>”, and “src =”, respectively, “<a” and “<a” are included in the display control information. It means that the portion between “</a>” and the portion described immediately after “src =” is the web page identifier of the link destination web page.

  Next, the operation of the terminal device 100 of this embodiment will be described.

  FIG. 5 is a flowchart showing processing performed by the CPU 102 of the terminal device 100 by reading the object cutter program 110 into the RAM 103 and executing it.

  First, the CPU 102 of the terminal device 100 displays a screen for inputting a URL (Uniform Resource Locator) as a Web page identifier and a keyword as a search condition on the display 108 (S10). FIG. 6 is an example of the input screen 600. The input screen 600 includes a URL input field 601 for inputting the URL of a Web page for extracting an object, a keyword input field 602 for inputting a keyword of the object to be extracted, and an OK button 603. Here, the user inputs the URL and the keyword into the URL input field 601 and the keyword input field 602 from the keyboard 106, respectively.

  Next, the CPU 102 of the terminal device 100 transmits a Web page acquisition request to the Web server 200 based on the received URL of the Web page. The processing means of the Web server 200 transmits the display control information of the Web page for which the acquisition request has been made to the terminal device 100 based on the received Web page acquisition request. FIG. 7 is an example of an HTML file as display control information received by the terminal device 100. The HTML file 700 is an object of a character having a hyperlink “<a href =” http: // xxx / sub-page1. htm "> SUB-PAGE1 </a>" 701 and "<img src =" picture1. gif ”>” 702. Then, the CPU 102 of the terminal device 100 stores the received HTML file 700 as display control information in the HDD 109 (S20).

  Subsequently, the CPU 102 of the terminal device 100 extracts the URL of the link destination Web page from the HTML file 700 stored in the HDD 109 as follows.

  The CPU 102 of the terminal device 100 refers to the Web page identifier extraction condition database 112 and extracts an object start identifier, an object end identifier, and an extractor identifier associated with a combination thereof. Subsequently, the CPU 102 of the terminal device 100 is a part sandwiched between the object start identifier and the object end identifier extracted from the HTML file 700 stored in the HDD 109 and is described immediately after the extraction unit identifier. Is extracted as the URL of the linked web page (S25).

  For example, in the case of the HTML file 700 in FIG. 7, the CPU 102 of the terminal device 100 extracts the URL of the linked web page as follows. The CPU 102 of the terminal device 100 refers to the Web page identifier extraction condition database 112 and uses “<a” as the object start identifier, “</ a>” as the object end identifier, and the extractor identifier associated with these combinations. Take out “src =”. Subsequently, the CPU 102 of the terminal device 100 is described from the HTML file 700 of FIG. 7 between “<a” and “</ a>” and immediately after “src =”. "" Http: // xxx / sub-page1. html "" is extracted as the URL of the linked web page.

  Then, based on the extracted URL, the CPU 102 of the terminal device 100 transmits a link destination Web page acquisition request to the Web server 200. Subsequently, the processing unit of the Web server 200 transmits the HTML file of the Web page for which the acquisition request is made to the terminal device 100 based on the received acquisition request for the linked Web page. FIG. 8 is an example of the HTML file 800 of the linked web page received by the terminal device 100. The HTML file 800 includes an object “<img src =” picture2. gif ">". Then, the CPU 102 of the terminal device 100 stores the received HTML file 800 as display control information in the HDD 109 (S30).

  As described above, the CPU 102 of the terminal device 100 displays the HTML file 700 of the Web page corresponding to the URL input from the keyboard 106 on the input screen 600 and the HTML file 800 of the linked Web page derived from the hyperlink of the Web page. Are stored in the HDD 109. Here, in the present embodiment, the CPU 102 of the terminal device 100 displays the Web page display control information corresponding to the URL input from the keyboard 106 and the link destination Web page display control information derived from the hyperlink of the Web page. Only from the web server 200 and stored in the HDD 109, the web page identifier of the web page further derived from the hyperlink of the link destination web page is extracted by the above-described method, and the web page identifier is extracted. The corresponding Web page display control information may be received from the Web server 200 and stored in the HDD 109.

  Next, the CPU 102 of the terminal device 100 refers to the standard object database 111 and extracts the object start end identifier and the object end identifier associated with the object start end identifier. Then, the CPU 102 of the terminal device 100 is a portion sandwiched between the object start identifier and the object end identifier extracted from the HTML file stored in the HDD 109, and input from the keyboard 106 on the input screen 600. The object including the keyword is extracted as an object that satisfies the search condition (S35). Subsequently, the CPU 102 of the terminal device 100 stores the extracted object in the storage unit.

  For example, when the keyword input to the keyword input field 602 on the input screen 600 is “gif”, the CPU 102 of the terminal device 100 reads <img src = from the HTML files of FIGS. 7 and 8 stored in the HDD 109. “picture1.gif”> and <img src = “picture2.gif”> are extracted as objects satisfying the search condition and stored in the HDD 109. FIG. 9 is an example illustrating a state in which the CPU 102 of the terminal device 100 stores an object that satisfies the search condition in the HDD 109.

  As described above, when an object is extracted from display control information of a predetermined Web page and a linked Web page guided by a hyperlink of the Web page, the Web page identifier corresponding to the linked Web page must not be input. Can also extract objects.

  The objects stored in the HDD 109 can be used as follows.

  The CPU 102 of the terminal device 100 displays a display entity corresponding to the stored object, such as a figure or a table, and a button associated with the object on the display 108. Subsequently, when the button is pressed by the mouse 107, the CPU 102 of the terminal device 100 adds the object associated with the pressed button to the display control information of the new Web page, and creates a new Web page.
