The present invention relates to a method and a system for providing web content based on mobile internet using web page segmentation. More specifically, a web page based on a wired internet is analyzed for a dome tree structure of a web page. By providing a mobile terminal through a mobile internet by dividing it into a plurality of mobile pages, a mobile internet-based web content providing method and a web page segmentation method using a web page segmentation that can receive a user-friendly wired internet-based web page through a mobile terminal. It's about the system.

In general, the method of using a computer-based wired Internet can be divided into a method of using a search engine and a method of using an address of a specific web page. In order to apply this method to the mobile Internet, a mobile web search engine such as an internet search engine is required.

For example, search engine development companies such as Google ^TM and NAVER ^TM developed various mobile search engines while suggesting various ideas based on their successful experience in search engines. 1 is a diagram illustrating an example of a mobile internet based search engine provided by Google.

In addition, a technology for directly accessing a specific mobile-based web page has also been proposed in the mobile Internet, which is commonly referred to as a mobile address or wink (WINC). 2 is a diagram illustrating an example of connection of the mobile Internet using wink.

However, the mobile Internet service as described above has a problem in that standardization of contents provided in the form of an additional service rather than the main function of the mobile terminal is not made. This problem originates from the fact that the browser embedded in the mobile terminal to provide the content service is different. The problems caused by the different browsers are summarized as follows.

First, mobile terminals are manufactured based on various shapes and hardware performances of many companies, and have not been standardized yet due to the development of production efficiency. In particular, in the browser embedded in the mobile terminal, different browsers, such as UP and ME, are embedded depending on the company providing the service, and even though the browser is the same, the image format to be played may be different. This means that the appearance that may appear on the screen when playing the same content may vary depending on the type of mobile terminal, the type of embedded mobile web browser, and the type of communication company.

In addition, in the case of an image having a design aspect, it may convey different meanings depending on the position. Since the same content is not provided while using the embedded font for each mobile terminal, there is an increasing number of cases in which text data is provided to provide a service. Therefore, the content for the limited mobile terminal is being produced and serviced, and to improve the service quality of the mobile Internet is trying to provide a service using many images. For this purpose, it must be composed of the image format that can be recognized by the browser.

In addition, in order to minimize the amount imposed by the packet and to minimize resources for image reproduction in the terminal, appropriate data should be processed and transmitted. To this end, it is necessary to accurately grasp the information on the mobile terminal used based on the analyzed data for many mobile terminals, and the service should be performed by performing adaptive resource conversion based on the user's mobile terminal information. As such, if the service is not adaptive to each mobile terminal, there is a problem of having low quality or rising service cost.

Second, despite the fact that the mobile internet service is composed of the contents of the contents, even though it is desirable to provide the same or similar contents to all the mobile terminals, that is, depending on the mobile terminal to which the contents accessed using the wink are connected, The services provided by the different browsers show completely different phenomena as well as configuration. This is a problem caused by configuring a completely different mobile site for each mobile terminal due to different markup of content and difficulty in producing XSL.

Third, in the current mobile internet and wired internet environment, even a company operating a normal wired internet-based web page can play it when a web page created based on HTML is connected to a mobile terminal equipped with a mobile internet-based browser. Since it is impossible to manufacture and operate a site dedicated to the mobile Internet by the method described above, there is a disadvantage in that the cost is doubled.

On the other hand, with the spread of PDA terminals, researches related to the reconstruction of web pages have been continued to receive web pages produced based on HTML using PDA terminals.

For example, "MOBILE ACCESS TO THE INTRANET: WEB CONTENT MANAGEMENT FOR PDAS (Maria Magnusson and Dick Stenmark, Ninth Americas Conference on Information Systems, pp 1989-1997, 2003)" or "Efficient Browsing of Web Search Results on Mobile Devices Based on Block Importance Model (Xing Xie, Gengxin Miao, Ruihua Song, Ji-Rong Wen, Wei-Ying Ma, IEEE Int'l Conf, PerCom 2005) "explains how to split a web page to serve a web page on a PDA device. It is starting.

However, mobile terminals such as mobile phones, unlike PDA terminals, have limitations in providing web pages to mobile terminals through the division of web pages based on the PDA terminals due to limitations in hardware processing speed and memory recording capacity. There is.

In addition, as described above, various web browsers of the mobile terminal, for example, XML-based WML, WML Script, XHTML or HTML-based mHTML, cHTML, s-HTML can be provided in common to the service can be provided none.

Accordingly, an object of the present invention is to provide a mobile internet-based web content providing method capable of playing a wired internet-based web page to a mobile terminal through the mobile internet.

In this case, in the step (c), the mobile object that can be played through the mobile internet may include data having at least one property of an image and text in the dome tree structure.

In addition, the step (e) comprises the steps of: database the terminal information including information on the resolution of the mobile web browser and the mobile terminal installed in the mobile terminal; Generating the mobile page by grouping the mobile objects to be playable on the mobile terminal based on the information on the resolution of the mobile terminal; And converting the mobile page to be playable in the mobile web browser installed in the mobile terminal.

Here, the step (c) may be extracted to the mobile object based on at least one of a length, a resolution, and a position on the web page of a corresponding image among data having an image attribute in the DOM tree structure. Making a step; A region of the web page is extracted from the DOM tree structure, and a mobile page is generated for data belonging to the region of the web page from the DOM tree structure. It may include at least one of the step of extracting the mobile object.

On the other hand, the above object is, according to another embodiment of the present invention, a mobile terminal for transmitting a service request signal including a URL for a web page via the mobile Internet, and displays the mobile page received via the mobile Internet; Analyze a dome tree structure of a web page corresponding to the URL of the service request signal received from the mobile terminal, and search each node of the dome tree structure depth first (DFS: Depth First). Search and extract at least one mobile object to be transmitted to the mobile terminal, and generate at least one mobile page obtained by dividing the web page using the mobile object in a format that the mobile terminal can reproduce. It can also be achieved by a mobile Internet-based web content providing system using a web page segmentation, characterized in that for converting, the converted mobile page comprises a web center for transmitting to the mobile terminal in a predetermined order.

Here, the mobile object that can be reproduced through the mobile internet may include data having at least one property of an image and text in the dome tree structure.

The web center may include: a terminal database storing terminal information including information about a resolution of the mobile terminal and a mobile web browser installed on the mobile terminal; Based on the information on the resolution of the mobile terminal, the mobile object is grouped to be playable on the mobile terminal to generate the mobile page, and the mobile page is converted to be playable on the mobile web browser installed in the mobile terminal. It may include a page generation unit.

The web center may be configured to extract the mobile object based on at least one of a length, a resolution, and a position on the web page among data having an image property in the DOM tree structure. ; A region of the web page is extracted from the DOM tree structure, and a mobile page is generated for data belonging to the region of the web page from the DOM tree structure. The mobile object may be extracted by at least one method of extracting the mobile object.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The web content providing system based on the mobile internet 50 using web page division according to the present invention, as shown in FIG. 3, includes a mobile terminal 10 and a web center 30.

The mobile terminal 10 includes a mobile web browser for reproducing data received through the mobile internet 50. In addition, the user of the mobile terminal 10 receives the service request signal including the URL for the web page in order to receive the content for the web page on the wired Internet 70 produced on the basis of HTML to the mobile Internet 50 Transfer to the web center 30 through.

Here, the mobile terminal 10 receives a mobile page to be described later transmitted from the web center 30 in response to the service request signal and displays it on the screen through the mobile web browser.

The web center 30 is connected to the mobile terminal 10 through the mobile internet 50, and accesses a web page produced based on HTML through the wired internet 70. Here, the web center 30 according to the present invention is an example of accessing a web page through the HTML-based wired Internet 70, but in the case of accessing the HTML-based web page may be a wireless Internet. In addition, in the present invention, the content of the HTML-based web page refers to reproduction of the content described by the HTML standard using a standardized browser.

The web center 30 receives a service request signal including a URL for a web page received from the mobile terminal 10 and accesses a web page corresponding to the URL. The web center 30 analyzes the DOM tree structure of the web page and searches each node of the DOM tree structure through a depth first search (DFS) method.

The web center 30 extracts the mobile objects to be transmitted to the mobile terminal 10 among the web pages searched through the depth-first search method, and generates mobile pages using the extracted mobile objects. Here, the mobile object that can be reproduced through the mobile internet 50 may be composed of data having image or text attributes.

The web center 30 converts the mobile pages into a format that the mobile terminal 10 can reproduce and transmits the pages to the mobile terminal 10 in a predetermined order. Accordingly, the mobile terminal 10 displays the mobile page transmitted from the web center 30 on the screen, thereby providing the user with the HTML-based web page through the mobile terminal 10.

4 is a diagram showing the configuration of a web center 30 according to the present invention. As shown in the figure, the web center 30 may include a call manager 31, a terminal database 33, and a page generator 32.

The page generator 32 accesses a web page corresponding to the URL included in the service request signal received from the mobile terminal 10 in response to a request from the call manager 31. The page generator 32 analyzes the dome tree structure of the web page to which the web page is connected, and searches each node of the dome tree structure (DFS: Depth First Search). The navigation method is used to determine the mobile object to be registered in the mobile page.

Here, the page generator 32 groups the mobile objects to be reproduced in the mobile terminal 10 based on the information on the resolution of the mobile terminal 10 stored in the terminal database 33 when the mobile page is generated. The page generator 32 generates a mobile page in a format that can be reproduced by the mobile web browser based on information on the mobile web browser installed in the mobile terminal 10 stored in the terminal database 33.

In addition, the page generator 32 may extract a mobile object based on at least one of a length, a resolution, and a position on a web page of a corresponding image among data having an image attribute in a DOM tree structure. In addition, the page generator 32 extracts a region of the web page from the dome tree structure, and stores data belonging to the region of the web page in the dome tree structure as one mobile. You can extract it as a mobile object to create a page.

Hereinafter, a method of reproducing the HTML-based web page as a mobile page through the depth-first search method by the page generator 32 of the web center 30 according to the present invention will be described in more detail.

Analysis using Dome Tree Structure of HTML-based Web Pages

HTML-based web pages are produced by combining various scripting languages and various technologies based on the HTML language by the W3C protocol. In order to generate various contents existing on the web page as a mobile page, a method of extracting important content in the web page and the extracted data must be converted into a form that can be reproduced in the mobile terminal 10.

In general, HTML-based web pages consist of a large collection of object data of various types. Text data and image data are common forms, and Flash or other object files are connected and serviced. In order to play these various objects, Web pages are running various plug-ins added to Internet Explorer in Microsoft. In contrast, mobile web browsers play content using resources that are limited to other platforms, depending on the company.

The homepage of Google ^TM shown in FIG. 5 is composed of a relatively small set of contents. FIG. 6 is a diagram illustrating a dome tree structure of a homepage of Google illustrated in FIG. 5.

Referring to FIG. 6, the DOM tree structure is divided into a HEAD Tag and a BODY Tag, and the TITLE, META, STYLE, SCRIPT, CENTER, DIV, FONT, B, A, IMG, It includes tags such as BR, FORM, TABLE, TBODY, TR, TD, FONT, INPUT, SPAN, LABEL, and A.

When detecting the contents of the web page shown in FIG. 5 in the DOM tree structure shown in FIG. 6, the content of 'hotdigi@gmail.com' is in the tenth node item, and the data is under BODY and under CENTER. , Under DIV, under FONT, and within B Tag. In this way, if you look at the data on the X axis of the web browser, you can see that it is located in 11, 12, and 13 terms.

In addition, it can be seen that it belongs to the same parent tag FONT, and it can also be seen that it is located at the far end node. That is, it can be seen that the content expressed in the web page shown in FIG. 5 is located at the extreme end on the dome tree structure shown in FIG. 6.

Here, looking for a mobile object that can be generated as a mobile page on the DOM tree structure shown in FIG. 5, the objects in text form 10, 11, 12, 13, 24, 25, 26, 27, 29 We can see that there are nodes 14, 42, 44, 46, 51, 53, 57, 58, 59, 63, 65, and object of image type.

Depth-First Searching of Dom Tree Structure

The web center 30 of the web content providing system according to the present invention uses a depth first search (DFS) method as a method for searching all modes of the DOM tree structure shown in FIG. 5. As an example. This means that when a search result for all nodes on the DOM tree structure shown in FIG. 5 is to be configured as a mobile page, extracting data by sequentially arranging terminal nodes consists of a DOM tree structure. This is because it is desirable for retrieving mobile objects from data. This makes it possible to search objects without duplication in order to analyze quantitatively large and complex mobile objects.

In detail, the depth-first search method is a method of finding and searching for a target node to a deeper depth in the vertical direction of a dome tree structure. If the path is over without encountering the target node, it goes upside down. Backtracking will continue the search with a path that has never been explored.

Depth-first searching saves the demand for storage space by storing only nodes on the current path, and can quickly find solutions even when the target node is deep. In the present invention, since the mobile object is searched through the depth-first search method, the mobile objects may be generated in order of the searched mobile objects by the depth-first search.

In addition, the tag searched through the depth-first search method is placed in a specific position of the mobile page. The placed mobile object generally has the content characteristic of the accumulated tag, so that the content of the next node can be represented after the position where the first node is represented.

Recognize the characteristics of creating data by wrapping it with many tags that modify it around the content that you want to deliver, which is the characteristic of HTML language that composes the web page, and modify the data into data to deliver to users. By removing the wrapping tag (Wrapping Tag) that can not be played on the mobile page, the original content can be extracted and played.

How to create a mobile page

The web center 30 extracts the mobile object on the DOM tree structure through the above-described method and generates a mobile content list based on the searched result.

Algorithm 1

Input: HTML DOM Tree Output: Mobile Contents List Composes the HTML DOM Tree of the currently selected web page. Get the best Element foreach DOM Tree Element begin if Element Child = 0 then begin if Element = Image then begin Register the image in the Contents List. endif else if Element = Text then begin Register the text data in the Contents List. endif endif end

Referring to [Algorithm 1], the input content is a URL address to be converted, and the output data is a content list of objects to be generated as a mobile page. When linked by a URL address, the linked web page is analyzed using a DOM tree.

All elements can be connected by each element of the DOM tree. In order to extract a content list for mobile objects that can be registered in a mobile page, data having image and text attributes is extracted from many elements on a DOM tree.

Algorithm 2

Input: Mobile Contents List Output: Mobile Page Get the best element of the Mobile Contents List. posObj = 0; foreach Mobile Contents Element begin if posObj <device vertical size then begin if Element = Image then begin Add the image to the mobile page. posObj + = rectImage; endif else if Element = Text then begin Add text data to the mobile page. posObj + = rectText; endif endif if posObj> device vertical size then begin Add a new mobile page. Register a link to a neighbor page. posObj = 0; endif end

Meanwhile, the mobile page may be generated using [Algorithm 2], targeting the content in the mobile content list, which is a set of mobile objects that can be generated as mobile pages in the web page.

The unit in which the mobile page is generated may be generated based on the resolution of the mobile terminal 10. For example, assuming that the mobile terminal 10 has a standard size of 240 * 320, the mobile page may be generated in 240 * 320 size units.

The generated mobile page can check the contents using scrolling at a low resolution. In addition, it can be played back on a small screen at high resolution. By adding data from the mobile content list one by one and increasing the vertical resolution of the added content, the size of the currently reconstructed mobile page can be obtained, and the size determines whether to generate a new mobile page.

In addition, due to hardware limitations of the mobile terminal 10, one mobile web page is generated in a vertical resolution unit, and can be used as a content that can be quickly accessed using the mobile terminal 10. The hardware allocated to the web browser in the display device and the mobile terminal 10 can be used with a margin.

Algorithm 3

Input: Text data URL address Location to register Output: Mobile Page if pageParser! = Null then begin Creates a text object. Register the location of the object to register. Register the text data. if URL! = null then Register the URL in the begin object. Displays the URL in the object (color-blue, underlined). Endif Returns the location information of the currently registered object. endif

[Algorithm 3] is an algorithm for adding data having a text attribute among mobile objects of a mobile content list to a mobile page. Create a text object in the vertical position of the current mobile page and register the contents of the text.

At this time, if there is a hyperlink attribute among the registered contents, it is registered as a URL, and an object having the attribute of the URL may be registered as a content type having a blue underline. When the registration is completed, the size information of the currently registered object is returned.

Algorithm 4

Input: Location URL of image data Location information to register Output: Mobile Web Page if pageParser! = Null then begin Creates an image object. if image data location = network then begin Download the image internally. Register the endif image. if image size> device horizontal size then begin Reduce the image by the ratio of the device horizontal size to the horizontal size of the image. endif Register the location of the object to register. if URL! = null then Register the URL in the begin object. endif Returns the location information of the currently registered object. endif

[Algorithm 4] is an algorithm for adding data having image attributes among mobile objects of the mobile content list to the mobile page. Create an image object in the vertical position of the current mobile page and register its contents.

The processing is performed by distinguishing whether the content exists in the network or the content exists locally according to the type of the registered image. This is a distinction caused by the difference of the current resource size and other information when accessing the resource. If there is a hyperlink attribute among the registered contents, it is registered as a URL. An object with the attribute of the URL has a blue underline. It is registered as a content type. When the registration is completed, the size information of the currently registered object is returned.

Create important image based mobile pages

를 보면 다음과 같다.In the present invention, when generating a mobile page based on the content of the web page, even if the loss of some of the entire mobile objects, considering the loss of the mobile object can be selected based on the important image to improve the quality of service. Because it takes a lot of resources and time to analyze the resources,

,

Look like this:

The value of is not too long for a particular resolution, and images larger than 400 pixels can be selected as the image that is important to be selected and rendered on the mobile page.

By applying the design element image with less design effect, considerable resource savings can be achieved. In other words, even if some images are removed, it is possible to obtain an effect for improving a service without any significant obstacle in conveying meaning.

[Equation 2]

,

By the method, some images are selectively registered among a large number of image data in a web page in consideration of the size information and the location information of the content currently expressed. By registering some excellent image data among a large amount of image data on a mobile web page, it is possible to improve the performance of the web center 30 that provides a conversion to fit the display of a mobile user in real time and provides unnecessary mobile web users. By reducing page movement, you can save money on the consumption of mobile web services.

Create mobile page by region

Algorithm 6

Input: Mobile Contents List Output: Mobile Page Get the best element of the Mobile Contents List. posObj = 0; foreach Mobile Contents Element begin if Element = Region then begin Add a new mobile page. Record the Region Title. posObj = 0; endif else if posObj <device vertical size then begin if Element = Image then begin Add the image to the mobile page. posObj + = rectImage; endif else if Element = Text then begin Add text data to the mobile page. posObj + = rectText; endif endif if posObj> device vertical size then begin

[Algorithm 6] is a modification of [Algorithm 2], which adds a function to start a new mobile page when an element in the mobile content list is a region. In other words, if there is a code corresponding to a region, a new mobile page is created and elements of the mobile content list after the region are added as mobile objects. In addition, the chain is configured to enable the movement of the mobile page in the same region (Region) unit in the mobile content list.

Hereinafter, a web content providing method according to the present invention will be described with reference to FIG. 7.

First, the user accesses the web center 30 through the mobile terminal 10 (S10), and transmits a service request signal including the URL of the web page to be connected to the web center 30 (S10).

When the service request signal is received (S20), the web center 30 accesses the web page based on the URL of the service request signal (S21). Then, the web center 30 generates and analyzes a dome tree structure of the accessed web page (S22), and as described above on the dome tree structure, the mobile object through a depth-first search method. It is extracted (S23).

The web center 30 generates a mobile page using the extracted mobile object, and converts the generated mobile page into a format that can be reproduced in the mobile terminal (S24).

Then, the web center 30 transmits the first mobile page of the mobile page to the mobile terminal 10 (S25), and the mobile terminal 10 receiving the mobile page from the web center 30 corresponds to the mobile page. Is displayed on the screen (S12, S13).

Here, when the user selects the movement of the mobile page using the mobile terminal 10, the mobile terminal 10 transmits the page movement command to the web center 30 as a service request signal (S14), and the web center The page movement command is received as the service request signal (S26), and the next mobile page is transmitted to the mobile terminal 10 (S25).

Here, step S27 of FIG. 7 is a process for selecting a case in which a page moving command (or service request signal) from the mobile terminal 10 requires access to another web page, and access to another web page is requested. If it is transmitted through the step S21 to S25 the mobile page generated for the new web page to the mobile terminal 10.

Through the above configuration, the web content providing system according to the present invention can expect the following effects.

In order to activate the wireless web service, a system for providing a stable wireless web service of MPEG-21, which is not another service according to a user, was completed, and the existing web content was automatically converted according to the spread of the system according to the present invention. It becomes available in the system according to the invention. In addition, since the wireless web page provided according to the present invention is useful content such as a web page based on the existing wired Internet 70, the user may feel intimate and maximize the accessibility of the user.

In addition, many mobile terminals 10 that are not standardized are provided with the same wireless web content, thereby providing the latest contents to various portable terminals in the same manner, thereby solving the problem of lack of contents of various mobile terminals 10 in a ubiquitous environment. It becomes possible.
