KR100407206B1 - Pre-processor and method and apparatus for processing web documents using the same - Google Patents

Abstract

The present invention allows a web browser to perform a prebrowsing function by preprocessing a web document on the World Wide Web using a web authoring language (programming language) without the need for a separate web browser programming process for performing a prebrowsing function. A preprocessor and a method and apparatus for processing a web document using the same are provided. The preprocessor contains at least one of the original text, the portion that is shown in the main window, the ability to show the document linked to the prebrowse window when a prebrowse event occurs, and at least one portion of the invisible portion that downloads the prefetched document. It is a preprocessor that generates and stores the code corresponding to the original text in advance, or it is inserted into the original text in script form and sent to the client together with the original text. When the document is loaded in the browser window, the prebrowse links included in the original text are inlined with each other. It is a self-documenting pre-browser preprocessor script program with the ability to download to a frame and prepare it for viewing. Pre-browsing is the function to view the contents of the pre-browsed document before the user clicks a specific pre-browse link in the pre-browse request document requested by the document creator. Regardless of the request, it is received from the server in advance and stored on the client computer. The method includes inserting a pre-browse request into a desired web document to generate and save a pre-browse source file; When a web page is requested by a web browser into which at least one prebrowse link is inserted in the web document, a prebrowse-ready document with a prebrowser function is created by preprocessing a prebrowser source file, or Transmitting a web document from a web server to a web browser, the web document being created by attaching to a prebrowsed document in the form of a prebrowser preprocessor script so that prebrowsing can be implemented in an existing web browser; And transmitting the pre-browsed web documents linked to the pre-browse links in the web page so that they can be expressed through the web browser and sent to the client even if there is no user request for the web documents. do. Thus, when a pre-browse event occurs for any one of the pre-browse links in the web page, the web document previously stored in the inline frame or cache is displayed through the web browser. Also, when the prebrowse link is clicked, you can see the documents stored in the cache without having to go to the server to get them. As a result, the waiting time perceived by the web user can be further reduced, and the user can view the linked web document without leaving the URL displayed on the web browser.

Description

Pre-processor and method and apparatus for processing web documents using the same}

The present invention relates to a preprocessor and a method and apparatus for processing a web document using the same. More particularly, only a web writing language (programming language) is required without a separate web browser programming process for allowing the web browser to perform a pre-browsing function. Pre-processing pre-browsed web documents that are pre-browsed on the World Wide Web, or inserted into the original text of the web document to pre-browse when the document is loaded into the browser window Pre-processing of the form and the web document with pre-browsing function without loading the mouse with the mouse is called in advance, loaded into the inline frame, stored in the cache and mouse over the pre-browse link or pre-browse icon in the web page Or click to preview The present invention relates to a web document processing method and apparatus for displaying a web document in a web browser.

Here, the pre-browsing function is a function of prefetching (downloading) a document of a hyperlink requested by a document creator using a traffic bandwidth that is idle while the user is viewing a web page, and a linked site without leaving the current page. This is the function to make the contents of the pre-browsing event visible. In addition, the prebrowse event is an event that requests the contents of a page linked to the prebrowse to be displayed in the main window (or a part thereof) or the prebrowse window through an input device such as a mouse. The easiest example is to place the mouse on the prebrow icon. An example of generating an event by hovering (rolling over) is an example.

The World Wide Web (WWW) is a wide area hypermedia information retrieval network that provides access to web information internationally through networked hypertext computer servers and clients. Hypertext is an information presentation method that allows a highlighted word or hypertext link to point to other hypertext documents. A hypertext link will be shown to indicate that it is a link embedded in a picture, or as an example underlined or otherwise highlighted word or sentence. Web pages (or hypertext pages) may be multimedia objects such as text, graphic (still) images, and audio or moving picture recordings.

In general, users of the WWW do not like to wait for the results when accessing a web page and loading web documents linked to the web page. That is, users requesting a web document will either avoid using a web page that takes a long time to load the web document or complain about such a web page. The network latency that occurs when accessing web pages provided by web servers is being solved by increasing the speed of internet communication networks. This is because a high speed communication network can significantly reduce the time required to bring a web document or web page from a web server to a client's web browser. However, the waiting time perceived by the user, that is, the time required for the user to request a web page and then view the web page, and the waiting time for loading the web documents linked in the web page still need to be improved. This is because most of the traffic bandwidth is wasted while the user reads the document because it takes time for a person to read the web document.

Conventionally, a prefetching technique for reading a web document in advance is disclosed in U.S. Patent No. 5,802,292. However, this is a request for retrieval of a client computer system currently requested by a server prediction based on statistics on past requests of client computer systems. By prefetching one or more entities, the client computer prefetches only the predicted entities (or web documents) of the user's search requests. There is still a need for latency to recognize.

In addition, the method disclosed in Korean Patent Application No. 2000-4043 filed on January 27, 2000 (name of the invention: prebrowsing method of web documents) has a separate prebrowsing program on the server side or client side. However, the pre-browsing method of the web document was executed, but this also has the inconvenience of embedding or installing a separate program.

Accordingly, an object of the present invention is to preprocess a prebrowse source file in which a prebrowse function is added to a web document without a separate prebrowse program, to perform a prebrowse function, or to be inserted into an original text and loaded in a browser window. Provides a preprocessor in the form of a prebrowse script that allows

Another object of the present invention is to modify the web browser or to install a separate program, such as pre-browse function without the need for a separate programming process for the web browser to perform the pre-browsing function, pre-browsed requested document By storing a document of specific pre-browse links in the web browser inline frame and cache in advance and displaying at least a part of the specific web document immediately when the user requests a pre-browse event such as a mouseover, the user The present invention provides a method and apparatus for processing a web document that can reduce a waiting time until a specific web document is displayed and recognized by clicking a link.

Another object of the present invention is to receive all or part of a page linked to the current page in an invisible frame of the current page and store it in a memory such as a cache, so that when an event such as a mouseover occurs or clicks the page link, The present invention provides a web document processing method and apparatus having a pre-browsing function so that a page can be directly brought from an inline frame or cache instead of a server.

Another object of the present invention is to provide specific web documents linked to a specific web link in a web page on a web browser of a client system while the user reads a web document called through an address (URL) input or a click of a hyperlink on a web browser. Disclosed is a method and apparatus for processing a web document that can be used to prefetch from a web server without a user's request, thereby effectively using the idling time of the client-server system.

Another object of the present invention is applied to a PC-based client-server system, web TV, PDA, web phone, IMT-2000, etc. When the user requests a document linked to a specific web link that appears on the web browser screen in advance, the user Provided is a web document processing method and apparatus that can reduce the waiting time until downloading a web document by immediately displaying at least a part of web documents linked to a specific web link on the screen.

Another object of the present invention is to pre-browse program execution results such as multi-search, bulletin board, or database search results such as dictionaries, thereby prefetching search results with a pre-browse request while the user is viewing a web document. Provides a method and apparatus for processing web documents that prompts the user to display the pre-browsed document in the main window (or part thereof) or the pre-browse window immediately when the user requests a pre-browse event such as clicking a link or hovering the mouse over a pre-browse icon. do.

It is still another object of the present invention to provide a method and apparatus for viewing a prebrowse linked document through a prebrowse event without leaving the current page.

According to the present invention for achieving the above object, a web document preprocessor for displaying web documents on a computer network on a web browser screen includes the original text of a web document having a pre-browser source and is displayed in a main window. part; A section containing the function to show the linked document in the prebrowse window when a prebrowse event occurs; And a program having a function of generating a code corresponding to at least one part of an invisible portion for downloading a prefetched document from an original text, which is an independent program or a script-type program inserted into the original text and preprocessing itself. do.

Preferably, the pre-browse request document includes a text content corresponding to the content of the pre-browse source file, a pre-browse icon for guiding the pre-browse event, an event handler for a pre-browse event request, and a pre-free It includes an invisible object (a pre-browsed document) that prefetches and saves the browsed document.

Preferably, the function of the preprocessor is driven in advance in the document editor through a separate program such as a web editor or when there is a request for a document or inserted directly into a document in the form of a script and transmitted to the browser.

According to another aspect of the present invention, a web document processing method for processing web documents on a computer network to be displayed on a web browser screen, the method comprising: inserting a pre-browse request into a desired web document to generate and store a pre-browse source file; When a web page requesting at least one pre-browser link in the web document is requested by the web browser, an existing web, which is created by preprocessing the pre-browse source file in a web editor or a text editor, or inserting a pre-browse script. Transmitting the converted file from the web server to the web browser so that the pre-browsing can be implemented in the browser; And transmitting the pre-browsed web documents linked to the pre-browse links in the web page so that they can be expressed through the web browser and sent to the client even if there is no user request for the web documents. It provides a web document processing method.

Preferably, the method further includes displaying the linked web document in response to a user's event for the prebrowse link.

Preferably, the pre-browse link is applied to a program execution result such as a search engine, a bulletin board, or a database search such as a dictionary function as well as a general web document link, and a pre-browse linked web document file while reading any one web document. And prefetching the search results.

Preferably, the file generated in the preprocessing step and transmitted from the web server, or the file converted by the script inserted when the pre-browse script is inserted and inserted into the web document is loaded into the web document having the pre-browse function. It is divided into a text section, a prebrowsing icon and a function for processing prebrowsing events, and an invisible frame section containing prebrowsed files.

Preferably, the body content is loaded first and displayed in a browser, and then the pre-browsed document files are stored in a storage unit by loading them in an invisible inline frame.

According to another aspect of the present invention, a web document processing apparatus for processing web documents on a computer network for presentation on a web browser screen, the web server selected by the user from the client system to the web server system to perform a document request Prebrowse-ready documents loaded from the system or existing in web pages (prebrowse-ready documents), that is, pre-processed using prebrowser web documents or text editors preprocessed using programs such as web editors. A web browser for loading a web document including a browser script; A storage unit for reading and storing at least a part of a web document linked in the web page having at least one pre-browse link; And event means for a user to perform an event on the pre-browse link or the pre-browse icon associated with the pre-browse link to display a part of the stored web document.

Preferably, the event means is an input means such as a mouse, a keyboard, a remote control.

According to another aspect of the present invention, in a web document processing method for processing web documents on a computer network for presentation on a web browser screen, an invisible frame (eg, an inline frame) of a prebrowsed page linked to the page is displayed. If you load it into a storage such as cache, and pre-browse event such as mouseover or mouse click, you can get the page which is pre-browsed from the frame or storage instead of the server. Provided is a web document processing method.

Preferably, instead of being received in an inline frame (iframe), the file is received using an object such as a frame, an object, a layer, an include file, and stored in a memory to have a pre-browse function. .

Preferably, when a prebrowse event such as a mouseover occurs by inserting a prebrowse icon next to a page link, a prebrowsed document in which the linked webpage is transmitted from the server or is already prefetched without leaving the current page. Display them in a free browser window.

Preferably, the pre-browse icon may inform the user by using different images for a web document that is already prefetched, for a web document that is currently prefetched, or for a web document that is not prefetched. have.

Hereinafter, with reference to the accompanying drawings will be described in detail the embodiments implementing the configuration and operation of the preprocessor and the web document processing method and apparatus using the same according to the present invention.

1 is a view for explaining the concept of a pre-browsing method when having a separate pre-browsing program before the present invention. The web page 13 which the user opens via the web browser 11 such as Internet Explorer or Netscape includes at least one specific link according to the present invention (hereinafter referred to as a pre-browse link) together with general links. Here, the general link is an existing link that allows the web browser to access the linked web document when the link is selected through a mouse click or the like. The prebrowse link is a prefetch (or predownload) function for the linked web document, the prebrowser function for displaying the contents of the web document without the web browser 11 moving to the URL of the linked web document, and the general link. This is a link that can provide functionality.

When a prebrowse link inserted in the web page 13 is read by the web browser 11 or located in an open window of the web browser 11, the prebrowse program 15 executes a web document linked to the prebrowse links. Even if the user does not request a web document, it can be retrieved from client systems or web servers, and then placed in a pre-browsed state that can be immediately displayed through a web browser. For example, the pre-browsing program 15 couples the pre-browsed web documents to the web page 13 by inserting, attaching or merging, or storing them in a cache or other storage means of the client system. In an environment where network latency can be ignored, web documents linked to prebrowse links will be located on web servers. Although the content of prebrowsed web documents can be combined into the current document or stored separately as a file, the combination of web document content will be considered the next paragraph. In an environment where linked web documents have a large amount of data or network latency must be taken into account, the web documents may be stored in the client system's memory or in a fast storage means.

The pre-browse program 15 described above may be embedded in the web browser 11 or implemented as a program that can be executed under a web browser basis such as a plug-in and a Java applet. The pre-browse program 15 may be implemented in a web server as a program such as a common gateway interface (CGI) or active server pages (ASP) that runs on the web server. As is well known, ASP is a program that allows script code to be processed on a web server even if the script code is not executed in a web browser. This pre-browsing program 15 is a user of the pre-browse links inserted in the web page 13 as long as the web browser 11 representing the web page 13 remains online with the web servers. Prior to requesting, you can pre-browse web documents linked to pre-browse links. When the software of the above-described example is used as the pre-browse program 15, web documents linked to the pre-browse links can be combined by inserting, attaching, merging or the like into the web page 13 in sequence or almost simultaneously. In the case of using such a dedicated pre-browsing program, as described above, a separate pre-browsing program has to be installed or installed on the server side or the client side.

Hereinafter, a general pre-browse concept for implementing a pre-browse function without a separate pre-browse program of the present invention will be described.

Hereinafter, a definition example and an implementation example of a prebrowse tag for web document creators applied to the present invention will be described.

I. Prebrowse Tag Definition

Meta specifications

It is located at the beginning of a web document and responds to subsequent prebrowse requests.

1.1 Default Search Engines Declaration

Used to simply define frequently used search commands.

<meta engine1 = "search request w / o parameter">

<meta engine2 = "search request w / o parameter">

For example, the search command for yahoo.com would look like this: <meta engine1 = "http://search.yahoo.com/bin/search?p=">

1.2 Default Prebrowse Symbol / Text Declaration

An image or text that is attached to a prebrowse link, and when you mouse over it, a prebrowse screen appears.

<meta pbicon = "url of gif file of the prebrowse icon">

or

<meta pbtext = "text">

For example, the command to bring up the pre-browse screen is as follows.

<meta pbicon = http: //prebrowse.com/image/pbicon.gif>

<meta pbtext = "Preview">

1.3 Default Prebrowse Off Option

<meta pb = off>

Ignore prebrowse requests in web documents.

1.4 Default Prebrowse All Option

<meta pb = all>

Request a prebrowser for all links in a web document.

1.5 Default Prefetch Off Option

<meta pb = np>

Respond to prebrowse events without prefetching for prebrowse requests in web documents. Used when the communication speed is very fast.

2. Prebrowse Tag

<a href=[url|engine1|engine2] pb=[all|preview|prefetch] width=width height=height> link text </a>

2.1For href = engine1 / engine2

Translate as below

<a href="search request w/o parameter" + "link text" pb=....> link text </a>

For example, if <meta engine1 = "http://yahoo.com?p=">, <a href=engine1 pb=all> linux </a> would be <a href = http: //yahoo.com? p = linux pb = all> linux </a>.

2.2 pb = all

Show the entire document in the prebrowse window. Prebrowse Tags in the document are ignored and the target of every link is the parent window.

2.3 pb = preview

Show the document between <preview> and </ preview> in the prebrowse window. The Prebrowse Tag is ignored and the target of all links is the parent window.

2.4 pb = prefetch

Combine the entire document into the current document or store it in memory, such as a cache. The Prebrowse Tag is saved and the target of every link is its own window. width and height are the width and height of the prebrowse window.

II. Implementation of prebrows

Pre-Browse Capabilities Implemented on the Client This section provides a general example of a Web authoring language.

This section explains how <a href=url pb=all> Prebrowsed Document </a> is changed in a program that implements a specific link included in a prebrowse page. The specific contents of the program are omitted because they are obvious to the programmer. For example, <a href="http://yahoo.com" pb=all> yahoo </a>, a link for pre-browsing yahoo.com, is available in the following 1, 2, 3 Will change to a command.

1. <img src = "icon_url" onMouseOver = "javascript: prebrowse (temporaryFile001)">

When a prebrowse event occurs, the prebrowse document is displayed in the prebrowse window. icon_url is the prebrowse icon image defined by pbicon above.

2. <a href="http://yahoo.com"> yahoo </a>

Clicking on the address of the file takes you to the link as you normally would.

3. <script> prefetch ("http://yahoo.com", temporaryFile001); </ script>

To respond to a prebrowse event, add code to the bottom of the web document to start prefetching after the page has loaded with code that corresponds to the prefetch and save command in the file. File names are not needed when HTML inline frame tags are used instead of functions such as prefetch and files are automatically stored in the cache. In this case, the code of 3 may be performed as follows. <Iframe name = frame1 src = http: //yahoo.com> </ frame> This code is pre-fetched and stored in an inline frame to respond to a prebrowse event. It is preferably added to the bottom of the web document by the prebrowse preprocessor to begin prefetching after the page has been loaded with code corresponding to the instruction.

The following is a descriptive description of the common features used to implement multiple prebrowse links and prebrowse events.

<script>

prefetch (address, file): Prefetches a prebrowse document and saves it to a file in preparation for a prebrowse event.

function prefetch (url, filename) {

Retrieve the web document at the given url;

Make the necessary conversions, such as changing the target window of the linked document;

Save the document contents to a file;

}

prebrowse (URL): Shows the web browser that requested the prebrowse in the prebrowse window in response to the prebrowse event.

function prebrowse (URL) {

If a prebrowse window is not open, open a new window;

Place the prebrowse window as the top level window;

Display the contents of an HTML file (stored in the cache) in a prebrowse window;

}

</ script>

Through the above-described pre-browsing program, the pre-browsing documents are pre-browsed to provide a pre-browsing function of displaying the pre-browsing document without a file transfer request generated by a user clicking a link.

Web documents linked to pre-browse links used in the present invention are web pages or web documents separate from the web page into which the pre-browse links are inserted, and include the entire contents of the web document or the web page provided by the web server. It may include only a part of the contents, or may include only a preview prepared separately from the web document. A web page that contains prebrowse link (s) is called a 'prebrowsing document'. The web page or web document linked to the prebrowse link inserted in the prebrowse page is designated as a 'prebrowsed document'.

In the present invention, instead of the above general embodiment, the present invention provides a specific implementation method of pre-browsing a web document pre-browsed in a client web browser. Of course, if you modify the web browser program so that the web browser can execute pre-browsing commands, the web browser can run pre-browsing, but here, without programming for a separate web browser, Also shows that the effect of prebrowsing can be substantially shown.

Collecting prebrowse documents on the server side and sending them to the client doubles Web traffic. On the other hand, collecting prebrowsed documents on the client can reduce the burden on the server and reduce traffic to and from the server. To prebrowse on the client, you usually need to use a web browser that supports prebrowsing or install a plug-in that supports prebrowsing. However, in the present invention, since the pre-browsing can be implemented by using a conventional web browser with a slight file conversion such as inserting a pre-browsing script, the web editor or the content provider does not need to install a separate pre-browsing program. It would be much easier to adopt the prebrow concept of the invention.

In the present invention, one prebrowse source file (simple.pbs) into which a prebrowse request is inserted is introduced. The source file is a file (file 2; simple.pbs) created by inserting a pre-browse request into a normal web document (file 1; simple.html). This file is preprocessed before being browsed by the preprocessor and converted into a web document (prebrowser request file: file 3; simple.phtml) on which prebrowsing is implemented. The preprocessor can be run manually by the author, or automatically by the server. The preprocessor performs prebrowsing preprocessing, receives a "document containing a simple prebrowse request" from the author of the web document, and reads it as a "prebrowse-ready document" in which prebrowsing can be executed without a separate program. Perform the conversion process (prebrowse preprocessing). As will be described later, the process of converting a prebrowse source file (simple.pbs) into a prebrowse request document (simple.phtml) is called prebrowse preprocessing. The preprocessor contains the text of the original text, the part that is shown in the main window, the part that shows the document linked to the prebrowse window when a prebrowse event occurs, and the invisible part that downloads the prefetched document. It generates and stores from the original text.

On the other hand, one pre-browsing script source file into which the pre-browsing request is inserted is a file created by inserting a pre-browse request and a pre-browser preprocessor in the form of a script into a normal web document. The prebrowse script performs prebrowsing preprocessing when the document is loaded into the browser, converts itself to a "document with a simple prebrowse request" created by the author of the web document, allowing "prebrowsing to be performed without a separate program." Document of the state ". The pre-browse request document (file 3: simple.phtml) and the pre-browse request document loaded into the browser and converted by the script are composed of the following parts.

a. Text corresponding to the content of the prebrowse source file

b. Prebrows icon (ⓟ) to guide you through prebrowsing events

c. Event handler (mouseover) when there is a prebrowse event request

d. Invisible frames for prefetching and saving prebrowsed documents (documents prebrowsed)

One thing to note is that if a prebrowsed document contains a prebrowsed document, there may be an infinite loop of prebrowsing, so all the functions related to prebrowsing in the above document should be disabled. This can be implemented by distinguishing the name of the document window and enabling the prebrowse function only on the main window.

To make it easier to understand, here are some examples of specific files.

The prebrowse source file (file 2) is a one-line prebrowse web document that contains only a link to the A site page. A link to site A contains a prebrowse request. The above file is converted to the following file (simple.phtml; file 3) through preprocessing.

File 1

simple.html (HTML file)

-------------------------

<a href=http://a.com/a.html> A </a>

-------------------------

Files 2

simple.pbs (source file)

-------------------------

<a pb=all href=http://a.com/a.html> A </a>

-------------------------

Files 3

simple.phtml (prebrowsed document file-phtml stands for prebrowsing html)

<a href=http://a.com/a.html> <img src = http: //prebrowse.com/pbicon.gif OnMouseOver = "Prebrowse (frame1)"> A </a>

<iframe name = frame1 width = 0 height = 0 src = http: //a.com/a.html> </ iframe>-File that is prebrowsed (invisible)

-------------------------

On the other hand, a case where the program in the form of a script is inserted into the original text of the pre-browse request document will be described. The prebrowse script source file 4 is a file containing a single-line prebrowse web document containing only a link to an A site page and an embedded prebrowse script. A link to site A contains a prebrowse request. The file above is loaded into the browser and converted to file 5 below. This conversion applies only to objects that have pb defined in the anchor tag, and the HTML code conversion / creation for these selected objects is obvious to familiar script programmers. You can see that File 3 and File 5 have the same functionality: File 4 <a pb=all href=http://a.com/a.html> A </a> <script> Contents of the prebrowse script < / script> ------------------------- File 5 <a href=http://a.com/a.html> <img src = http://prebrowse.com/pbicon.gif OnMouseOver = "Prebrowse (frame1)"> A </a> <iframe name = frame1 src = http: //a.com/a.html> </ iframe>-Free The file being browsed (loaded in an inline frame named frame1) <script> The contents of the prebrowse script <script> ------------------------- In the above description, It is assumed that Prebrowse (filename) and Prebrowse1 (filename) are event handlers that have a function of fetching a document (filename) on a frame that is not visible when a mouseover event does not occur in the prebrowsing icon image and displaying it in the prebrowse window.

The present invention is to enable the pre-browsing of the file to which the pre-browser is given in the existing web browser without a separate pre-browsing program as described above, the web document processing of the present invention with reference to Figures 2 and 3 The method will be described in more detail.

As shown in Fig. 2, the pre-browse request document 22 given the pre-browse request function described above is called by the web browser 11 on the client side (50). The body content of the web page 13 is displayed in the visible portion 42 of the browser screen along with the prebrowse event handler. Then, the web browser 11 on the client side by the pre-browse request document 22 sends the web browsers 24 and 28 to the pre-browsed documents 26 and 30 pre-browsed linked to the web page 13. Each of the pre-browse operations that are called from each other is performed (100). As such, the pre-browsed document files are prefetched 200, transmitted in an invisible frame 48 of the webpage 13, and thus stored in the cache 21 (300). As a result, when the user mouses over the pre-browse icon 46 or 47 in the browser window, an object such as a frame and a pre-browsed document stored in the cache 21 are displayed in the main window or the pre-browse window (400).

3A and 3B, when the webpage 13 visited by the user has a pre-browsed file, the web document A of the pre-browsed web server is pre-browsed. At this time, as described above, the pre-browse source file takes the form of simple.pbs as an example, which is processed and converted into a pre-browse request document 36 by the preprocessor 34. Alternatively, the pre-browse script source file is processed and converted into a pre-browse request document 36 by the pre-browse script embedded in the document when loaded into the browser. The prebrowse request document 36 provides a framework for loading a text document on a web browser screen and for loading prebrowsed documents in an invisible inline frame. The main document includes a main document (a) including an A link, a pre-browse icon (b), and an event handler (c) for displaying the A document in a pre-browse window in the case of a mouseover.

This divided prebrowse request document is displayed on a web page according to a function. For example, when the user does not hover over the prebrows icon or link, that is, the mouse out, the prebrowse event is displayed on the web page screen 42. A text document containing a pre-browse icon ⓟ and a link to page A indicating the name of the web document is displayed in the visible frame 42 of the web browser screen, and other pre-browsed web documents are present on the invisible frame 48. Is not displayed. However, as shown in FIG. 3B, when the user moves the mouse over a prebrowsing icon or link (in a mouseover), the web page screen 42 does not change, but the prebrowsed document in which the prebrowsing event occurs is invisible. Moved to the prebrowse window 46 and displayed in the cache or on the cache. However, when the pre-browse event is ended and the mouse is out, the pre-browse window 46 disappears. Of course, it is desirable that the prebrowse event continues and the window remains while the mouse is positioned over the prebrowse window. Here, the pre-browse web documents are displayed in the pre-browse window 46, but may be displayed in the main window 42 using an object such as a layer. In addition, although the pre-browsing function with prefetch has been described so far, even if there is no prefetching, the linked document can be viewed in the pre-browsing window without leaving the current page. In such cases, the pre-browse icon may be used by a user using a different image, for a web document that is already prefetched, for a web document that is currently prefetched, or for a web document that is not prefetched. You can let them know. For example, a pre-browse icon can be indicated by displaying yellow in the middle of the transmission, green if already prefetched and cached, and red if no prefetch has been performed.

In the present invention, a method of receiving and preserving a file to be prefetched using an invisible inline frame has been described. However, instead of being transmitted to an inline frame, the frame, object, and layer ( Pre-browsing can be implemented by receiving files and storing them in memory using objects such as layers) and include files.

4A to 4C illustrate an example in which the prebrowsing method of the present invention is applied to a search engine, various bulletin boards, and a dictionary function.

As shown in FIG. 4A, when the pre-browse function is applied to the search engine collection 402, after entering a search keyword into the search keyword window 400, if one of the search engines 404 is clicked, the search engine is clicked. Present your search results on a separate search page, and search engines with pre-browsing capabilities send the search results to the client's cache in advance while you read them, even while you are reading them. You can get the results of other search engines in advance and receive them without having to click.

In addition, as illustrated in FIG. 4B, when the post content is provided by the pre-browse function while the stored post content is read and read by clicking a post content in the bulletin board function, at least a part of the post content is pre-browsed in advance. Thus, the user can grasp the posting contents by simply holding the mouse.

In addition, as shown in FIG. 4C, a prebrowse link can be used to perform a dictionary function for words highlighted (or indicated) by this link. In this case, when the mouse is placed over a word to which the prebrowse function is given in the text, the meaning of the word may be displayed in the prebrowse window. That is, when a pre-browse event occurs, a pre-made search result for the web page or site indicated by the URL in the tag related to the pre-browse link will be shown through the above-described pre-browse window 46. In this case, it is possible to enhance the learning effect of Internet web users by linking various dictionary functions such as the Korean-Korean dictionary, the Korean-English dictionary, the English-Korean dictionary, and the English-English dictionary.

The present invention has been described so far by distinguishing between a web document having a pre-browser function and a web document not provided, even if the pre-browser function is provided to all web documents, or even if the web document does not have a pre-browse function, the current web browser If you add the pre-browsing function to the function, all web pages linked to the current page are sent to the invisible inline frame of the current page and stored in the memory such as the cache so that an event such as a mouseover occurs or the page link is clicked. You can also implement pre-browsing functionality for any web document so that the web page can be taken directly from the frame or cache rather than from the server.

The client system of the present invention is implemented as a general personal computer, a web TV, a PDA, a web phone, an IMT-2000, a computer-based Internet-enabled device, etc., and includes a web browser 11. The client system may include a communication device such as a wired / wireless modem and a network adapter card, a memory, a storage device, a central processing unit, and terminals for input / output such as a mouse, a keyboard, and a monitor. The web browser 11 also includes an internet communication program for communication devices such as a web navigation program used in a computer device. The pre-browsing web server system according to the embodiment of the present invention includes web documents 22, 26, and 30. Pre-Browse Web Documents and Web Documents Linked to Pre-Browse Links may use multimedia objects such as text, graphics (still) images, and audio or moving picture recordings made in a web authoring language such as XML, including HTML. The web documents used in the present invention are stored in a storage device of a web server system, such as a memory acting as a cache, a hard disk driver, or an optical storage medium.

In addition, in the present invention, a bribrowse function is performed through a preprocessor for generating and storing a prebrowse request document from a prebrowse source file in a web document, or a preprocessor stored in a prebrowse script form in a web document. It is to be understood that such a preprocessor is deemed to be included in the claims of the present invention if, for example, a prebrowser implementation is included in an editor (such as a web editor or a front page). In other words, when editing the link in the editor, the pre-browse can be selected and the output file of the editor enables the pre-browsing, that is, the case where the editor program performs the preprocessing is considered to be within the claims of the present invention. do.

As described above, the preprocessor and the web document processing method and apparatus using the same include inserting a pre-browse request into a web document, and inserting a pre-browse request into the pre-browse links among the links inserted in the web page without a separate pre-browse program. The linked web documents can be prefetched from the web servers to the client system where the web browser is located prior to the user's request for such web documents. Therefore, the waiting time perceived by the user surfing the web can be further reduced. Furthermore, the present invention enables viewing of web documents linked to prebrowser links embedded in a web page without leaving the URL currently displayed in the address field of the web browser. Therefore, a user who uses the web browser in which the present invention is implemented will feel as if surfing the web without actually surfing the web.

Although the embodiments of the present invention have been described so far, the present invention is not limited thereto, and various embodiments which can be modified and changed within the true spirit and scope of the principles described and claimed are also included in the scope of protection of the present invention. It should be understood that it belongs.
