Referring to FIG. 2, the apparatus 200 for generating a tab index of a web page of the present invention is connected to a web server 100 that provides a web service. The tab index generating device 200 includes a control unit 210, a storage unit 220, a user input unit 230, and an output unit 240.

The tab index generating device 200 generally operates as a user terminal device that requests a web page from the web server 100 as follows. The tab index generating device 200 accesses the web server 100 connected to the communication network, and requests the web server 100 to transmit a web page when the connection is completed. When the web server 100 transmits a web page according to a request of the tab index generating device 200, the tab index generating device 200 provides a user with the received web page using a browser.

In addition, the tab index generation device 200 selects another hyperlink included in the web page based on the user input signal. Hyperlinks contain information about the Uniform Resource Locator (URL) of a document of another web page on a web page. The hyperlink enables access to other web pages using URL information corresponding to the hyperlink selected by the user. The web pages exchanged between the tab index generating device 200 and the web server 100 are composed of Hyper Text Markup Language (HTML), and HTML has a structure of a multi-tree having an element as a node. Have

Hereinafter, the operation of each unit included in the tap index generation device 200 will be described in detail.

The controller 210 controls the overall operation of the tab index generation device 200 by controlling data transmission and reception between each unit included in the tab index generation device 200. The controller 210 may include a communication module that performs an operation for communicating with the web server 100 through a communication network such as the Internet. In addition, the controller 210 provides a web page to a user and provides an environment in which a browser, which is an application program capable of searching the web page, may be executed. The web page may be transmitted through the communication network as described above, but the tab index generation method of the present invention may be used when an HTML-format document is used even though the web page is not transmitted through the communication network.

The controller 210 generates user preference information generated based on a selection signal for selecting elements included in a web page used by the user. The selection signal for selecting elements is received from the user input unit 230 and transmitted to the controller 210. The user input unit 230 may be configured as a touch screen for receiving a user input, a button input key, and the like. The touch screen or button input key includes an input key for shifting the focus on the elements included in the web page displayed on the screen. In this specification, a key having such a function as a key board of a conventional personal computer is called a tab key. However, the name may be changed and called according to the type of the user terminal device.

Elements that can have a tab index in a web page include anchor elements such as URLs and input elements. Input elements include text, buttons, check boxes, passwords, and the like.

When selecting an element by a user input having the same function as the enter key of the personal computer and moving to another web page corresponding to the selected element, URL information, time connected to the URL, route information connected to the URL, and the like can be obtained. . The preference information may be generated using this information.

The preference information generated by the controller 210 includes at least one URL and the number of times of accessing each URL. In the preference information, the more the number of accesses to a specific URL, the higher the preference may be determined. Even when a user input signal for an input element is received, since a URL is generated when a search is requested, the URL and the number of times of access to the URL can be used as the preference information. The preference information may further include at least one information of a time of accessing the URL and a path of accessing the URL. In this case, the preference may be determined using the number of accesses of the URL, the URL access time, and the URL access path.

The controller 210 stores the preference information generated in this way in the storage 220. The control unit 210 interprets the received web page when a new web page is received. The controller 210 reads the preference information stored in the storage 220 and generates a tab index for the elements of the received web page based on the read preference information of the user.

To this end, the controller 210 checks whether information corresponding to an element of the web page is included in the preference information stored in the storage 220. The controller 210 checks whether there is a URL corresponding to an element of the web page in the preference information, and if there is a corresponding URL, retrieves a preference for the corresponding URL. The preference may be a number of times of accessing the URL, and may be represented by a value that may be determined using at least one of the number of times of accessing the URL and the time of accessing the URL. The preference may be determined using another method, and may be generated and stored whenever the preference information is stored in the storage 220.

The controller 210 generates a tab index for an element of the web page based on the retrieved preference. In this case, the controller 210 may generate the tab index by further using the tab index attribute information included in the web page and the order information of the elements included in the web page.

For example, the tab index for the element of the received web page is first determined in the order of the URLs having the larger value corresponding to the preference stored in the storage 220. Then, the remaining elements determine the tab index using the attribute information of the tab index included in the web page, and finally, in the case of an element that does not include the attribute information of the tab index in the web page, the elements are described in the HTML document. Refer to the order to complete the tab index of the elements included in the web page.

The controller 210 provides a web page based on the tab index generated in this way. The output unit 240 outputs the web page provided by the control unit 210. The output unit 240 includes a display device for displaying data received from the controller 210.

When providing a web page, the controller 210 outputs a predetermined number of elements with high preference among the generated tab indices so that the user can easily recognize elements of the web page with high preference. 240 may be controlled. Alternatively, the controller 210 may control the output unit 240 to display a tap index value for a predetermined number of elements having a high preference among the generated tap indexes.

Each time a user input signal is received from the user input unit 230 through a tab key for moving the focus on the element, the controller 210 generates a focus on the elements included in the web page in the controller 210. The output unit 240 is controlled to display sequentially moving according to the tap index.

In addition, the controller 210 may update the preference information whenever the selection signal for the elements included in the web page used by the user is input. Therefore, by creating a tab index using the updated preference information, the user can check what information he / she frequently uses, and can easily search for frequently used information by using the tab key.
