Description

Method of reforming webpage and providing webpage using it {Method of reformatting webpage and method of providing webpage using the same}

The present invention relates to a page reconstructor for extracting only necessary items from an HTML-based web page to be displayed on a terminal, and a method for providing a page by reconstructing a web page requested by the terminal and using the same.

Currently, a service that delivers information through web pages is popular. The web page is called and displayed in the client's browser while stored on the server. In the past, the client was mostly a PC, so the browser was also capable of displaying all the information of the web page. Recently, however, the client is often a terminal having various screen sizes other than a PC (hereinafter, referred to as a "terminal") in addition to a PC, such as a mobile phone, a PDA, an Internet TV, a smart phone, and a web screen phone. You are limited by the functionality of.

In the case of a terminal, the size of the display window is limited. Therefore, it is difficult to display everything on the web page. In addition, since the terminal cannot have a large number of input keys, there is a restriction that the web page is browsed with a limited number of key buttons. In addition, since the terminal connects to the server via a wireless medium, the amount of data, data transmission speed, connection fee, and the like in communication have been of great concern.

Therefore, in order to display the web page on the terminal, the web page in the server must be processed and transmitted to the terminal. This is called page reformatter or information extraction function. This function extracts only the information selected by the user from the contents of a general web page and creates a new page. This function is necessary because the display window of the terminal is limited. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a page reconstruction method comprising extracting only necessary items from an HTML-based web page and displaying them on a terminal, and reconstructing a web page requested by the terminal and sending the same to a terminal. will be.

1 is a system configuration diagram showing a typical connection between a terminal and a real server via the Internet. The call signal at the terminal is connected to the real server 18 on the Internet via the proxy server 16 via the switching network 12 and the IWF 14. The proxy server 16 acts as a proxy for the terminal and optimizes the WWW data according to the processing capacity of the terminal or the transmission capacity of the network. When requesting a web page by connecting to a real server from a terminal, in the real server, it is essential to convert the HTML document for the PC browser into the document for the terminal browser. As described in the "Explanation of Prior Art" column, the terminal should extract only the necessary items mainly based on the text because the display window is limited in size. As described above, the present invention provides a page reorganization method comprising a page reconstructor for extracting only necessary items from an HTML-based web page and displaying them on a terminal, and reconstructing a web page requested by the terminal and using the same. I am doing it.

Description of page reorganization method

2 is a screen display of a page reconstructor according to the present invention. We named it Node Extractor. The screen is composed of a window (ViewWebBr) 20 in which a web page is largely displayed, a tree view 22 in which a web page is displayed in a tree structure, and an window (ExtWebBr) in which content selected and extracted from the web page is displayed (24). It is composed of

The web page display window 20 has a window 26 for inputting an Internet URL address, and the URL is input to the address input window 26 to move to a desired site. In Fig. 2, "http://www.yahoo.com" is entered as an example. When the site corresponding to the input URL is opened, a web page is displayed on the web page display window 20, and the tree structure of this web page is displayed on the tree display window 22.

Dragging the content to be selected in the web page display window 20 activates the position of the selected node in the tree display window 22. That is, as shown in FIG. 2, when the text "Yahoo! Auctions" is dragged from the web page display window 20 and dragged onto the tree display window 22, the check box (□) in front of the corresponding item in the tree display window 22 is dropped. Is checked (√). At this time, if the content dragged up to the tree display window 22 is dropped onto the tree display window 22, if the selected node is a leaf node, the checkbox is checked together with the upper nodes. Rather, it checks the children of that node.

In the web page display window 20, the texts, images, and inputs can be dragged, and the texts can be dragged because the location of the tree is shown as a link. You can drag. Inputs can be dragged because the Clover image appears where the input box or hidden input tag is, just like an image, because it's in the tree.

When the checkbox of the tree display window 22 is selected as above, only the contents of the selected item are displayed on the extraction contents display window 24. That is, the node extraction is completed and the original web page is reconstructed and output to the extraction content display window 24. In addition, if the check box is deleted, the content displayed on the extracted content display window 24 immediately disappears.

In the above description, a method of reconstructing a page by extracting necessary items from an original web page using the page reconstructor according to the present invention has been described. Hereinafter, a method for actually implementing the page reorganizer will be described.

As shown in Fig. 3, in order to reconstruct the original HTML document (web page), the document is first analyzed to reconstruct the original in a tree form. 3 is a diagram showing a first step for reconstructing a newspaper homepage of "○○ Daily" into a page composed of only necessary items. In Fig. 3, the position of the menu table 28 called " ○○ Daily " at the top of the web page can be found in the tree structure. At the bottom of the menu table 28, it can be seen that the menu "Politics | Economic | Social | International | Cultural | Sports | Information and Communication | Capital Region | National | Cartoon | TV" is listed. The menu table 28 is configured in a hypertext manner so as to enter a corresponding page when each menu is selected (as in a normal HTML homepage).

FIG. 4 is a tree structure showing in detail the menu table 28 of " ○○ Daily " The position of each node in the tree structure of FIG. 4 may be displayed by arranging a number representing a child node of a parent node. For example, the position of the "HTML" node at the top of FIG. 4 is represented by "1". That is, it means that it is the first child node of the root node. In the same principle, "TEXT = politics" becomes "1 + 2 + 1 + 2 + 1 + 2 + 1 + 1".

However, it is difficult for human ability to find the location of a specific node in this way, so a utility called node finder is needed. Nodefinder parses the tree above and returns the following result:

[1] <HTML>

[1 + 1] <HEAD>

[1 + 1 + 1] <TITLE>

[1 + 1 + 1 + 1] Digital ○○ Daily

</ TITLE>

[1 + 1 + 2] <META ......>

[1 + 1 + 3] <SCRIPT ....> .... </ SCRIPT>

</ HEAD>

[1 + 2] <BODY>

[1 + 2 + 1] <TABLE>

[1 + 2 + 1 + 1] <TR>

[1 + 2 + 1 + 1 + 1] <IMG SRC = "abc.gif">

[1 + 2 + 1 + 1 + 2] <IMG SRC = "cde.gif">

In other words, the nodefinder attaches all nodes to the front of the node. Therefore, it assigns a unique ID that can be used to refer to a specific node.

If the homepage of FIG. 3 is desired to be displayed on the terminal as shown in FIG. 5, only the necessary nodes are displayed first in the tree structure as shown in FIG. 6 (darkly displayed nodes in FIG. 6). Next, all of the subnodes (ancestor nodes) of the nodes shown in FIG. 7 are also displayed. Next, as shown in FIG. 8, when all nodes not displayed are deleted, a new tree having only a necessary portion is completed. Arranging and serializing this tree yields the desired documents arranged as shown in FIG. Since this document only extracts the necessary items, it can be transmitted to the terminal and provided.

Page presentation method using page reorganizer

10 illustrates a method of providing a page using the page reconstructor described above. 10 to 12 illustrate an embodiment in which a proxy server is provided between the terminal and the real server, and the page reconstruction is performed in the proxy server. FIGS. 13 and 14 show a real server on the Internet without using a proxy server. By installing a virtual server and performing page reconstruction in the virtual server, an embodiment in which a terminal can obtain a processed web page document even if a proxy is not specifically set will be described.

First embodiment

A system configuration and a brief operation of this embodiment will be described with reference to FIG. (1) The setting terminal retrieves the original web page from the real server through the Internet, and sets which items to extract from the original web page. For example, it is set whether or not to extract the item as shown in FIG. (2) The setting result in the setting terminal is stored in the proxy server as a configuration file (* .cfg). The proxy server has a CFG DB, where the configuration file from the configuration terminal is stored. (3) When a user connects to the Internet and requests a website page set as described above, (4) the proxy server receives it and makes a request to the real server. (5) Real server finds web page of user's requested website and sends it to proxy server. (6) The proxy server loads the configuration file of the site from the CFG DB and converts the page (reorganize the page according to FIGS. 3 to 9). The converted page is transmitted to the terminal.

Referring to Fig. 11, the process sequence of this embodiment will be described. The setting terminal sets an item to extract for a web page of a specific site [100]. Next, a configuration file according to the result of the setting operation is transmitted to the proxy server for storage. In the CFG DB of the proxy server, a configuration file is stored [200]. As shown in FIG. 12, the configuration file is stored for each specific website and terminal type. Since there are many types of terminals at present, the purpose is to allow owners of each terminal to view a specific web page directly on their terminal.

After the configuration file is stored in the CFG DB of the proxy server, if there is a page request from the user through the terminal [202], the proxy server transmits the request signal of the page to the real server [204]. The real server constructs the requested page [300] and serves it to the proxy server [302]. The proxy server then searches the CFG DB to see if there is a configuration file for the page [206]. If there is a configuration file [210], the page is reconfigured according to the configuration file [212] and sent to the user [214]. If there is no configuration file [211], the loaded page is converted into a state that can be displayed on the terminal. Transmit [304].

In this embodiment, when a user makes a web page request, the request signal is transmitted to the real server through a proxy server, and the proxy server reconfigures the web page received from the real server according to a configuration file and provides it to the user terminal. will be.

Second embodiment

A system configuration and a brief operation of the second embodiment will be described with reference to FIG. (1) The setting terminal retrieves the original web page from the real server through the Internet, and sets which items to extract from the original web page. (2) The setting result in the setting terminal is stored in the virtual server as a configuration file (* .cfg). The virtual server is built in the internet space along with the real server. The virtual server has a CFG DB, where the configuration file from the configuration terminal is stored. (3) When the user connects to the virtual server by accessing the Internet, (4) the virtual server requests a web page from the real server. In the real server, the virtual server finds and responds to the requested web page. (5) In the virtual server, load the configuration file of the site from the CFG DB and convert the page (reorganize the page according to FIGS. 3 to 9). (6) The converted page is sent to the terminal.

Referring to Fig. 14, the process sequence of this embodiment will be described. In the setting terminal, an item to be extracted for a web page of a specific site is set [104]. Next, the configuration file according to the result of the configuration operation is transferred to the virtual server and stored [216]. The configuration file is stored in the CFG DB of the virtual server [216]. The configuration format is somewhat different from that of FIG. 12, and the configuration file is stored for each terminal type. In the first embodiment, the configuration file is also stored for each website, but in the second embodiment, since the user directly accesses the virtual server and enters the website, the configuration file is not stored for each website, but is set for each terminal type. Just save the file.

After the configuration file is stored in the CFG DB of the virtual server, when the user accesses the terminal through the terminal [218], the virtual server transmits a request signal of the corresponding page to the real server [220]. The real server constructs the requested page and serves it to the virtual server [306]. Next, the virtual server searches the CFG DB to see if there is a configuration file for the page, and if there is a configuration file, reconfigures the page according to the configuration file [222] and sends it to the user [224].

According to the present invention, it extracts only selected information from the contents of a general web page and reconfigures it into a new page and provides it to the user terminal, which can activate internet browsing, which is restricted due to the limited size of the display window, As a result, the Internet service can be used.
