Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Web document customization server for modifying a Web document specified by a client in a manner that is easy to read according to the request of the client and delivers the Web document to a client computer. The present invention relates to a server that manages individual information in a database and customizes the appearance of a Web document for each client individually based on the information.

[0002]

2. Description of the Related Art A typical form of use of the Internet is a variety of Web sites exhibited by many Web servers.
This means visualizing and viewing a document with a browser on a user computer (client). Web document authors often presume that a document is displayed on a standard display using a standard browser, and how the document is displayed and what it looks like (this is the display format). While thinking, write a Web document in a markup language. Here, the display format of the Web document intended by the creator will be referred to as an original format.

[0003] Japanese Patent No. 2994351 discloses that when displaying a Web document on a browser of a client, the Web document is brought as close as possible to the original appearance even if the platform of the client display system is not standard. The technology for displaying images is explained in detail. The point of this technique is to modify the description of a markup language for a Web document acquired from a Web server, thereby changing a display style such as a background color of a document, a color of a character, a character interval, and the like. This function is referred to as a proxy in this patent publication. The patent publication discloses a method in which a proxy is incorporated in a client to cooperate with a browser, and a method in which a proxy is mounted on a server such as an Internet connection service device.

[0004]

SUMMARY OF THE INVENTION The aforementioned Japanese Patent No. 299 is described.
In the technique of No. 4351, as described in paragraph number 0061 of the gazette, etc., the proxy performs the characteristics of the display system of the client (eg, operating system type, display resolution, browser type, video display card identification, video Web type in markup language to get the driver type, accelerator card type, etc.) or properties and modify the presentation accordingly before passing the web document to the browser accordingly.
The description of the document has been changed. This allows authors to create a single version of a consistently formatted Web document across many different types of display system platforms. This patent has such excellent effects.

[0005] The inventors of the present application have noticed that a request for displaying a Web document in a format different from the original format arises for a reason different from that of the patent. That is the situation for each person who views Web documents. For example, small letters are difficult to see for elderly people with advanced presbyopia, and specific color schemes are difficult to see for people with color vision deficiencies such as color blindness and color weakness. For these personal reasons, there is a demand to change the appearance of the Web document from the original.

[0006] A general browser also has a function of changing the background color and character size of a Web document as desired.
However, the function was extremely simple, which works uniformly for all Web documents, and did not significantly change the original display format according to the purpose of the user. For the purpose of measures against presbyopia or color blindness, they are displayed on a single screen at the expense of artistic elements such as the beauty and layout of the original format intended by the creator of the Web document. Even if the size of the document changes greatly, it is important to display the document in a format that is easy for the user to see.

To realize such a function, individual Web
Analytical processing must be performed to individually deal with the structure of the document and change the original appearance to a purposeful appearance. This requires sophisticated, large-scale software, and it is not reasonable to install it on individual clients. Also, even if such advanced software is installed in the client, the more sophisticated it is, the more troublesome the usage becomes and the burden on the user increases,
You will not be able to use the advanced features effectively.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a W
For those who do not have any technical knowledge about the description mechanism of the eb document, the Web document specified by the client is modified to be easy to read according to the request of the client and delivered to the client computer To provide a customization server.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A Web document customizing server according to an embodiment of the present invention described below is implemented as one function in a server system of a portal site "Yahoo!" operated by the present applicant, for example. Things. A user who wants to receive the service provided by the Web document customization server of this embodiment can use a personal computer (client) equipped with a general browser to provide a portal site "Yahoo!" on the Internet.
, Browse the web document customization service section information page, and first obtain a customization application web document.

FIG. 1 shows an example of a customization application form. This application form has user ID and password entry fields to identify the user when using the service, and also includes customization requirements such as age, degree of presbyopia, abnormal color vision, and the amount of documents to be viewed at one time. A pull-down list of four items is laid out. “Age” in the entry items of the customization application form is information for estimating the degree of document reading ability including comprehensive visual acuity. "Presbyopia" is information for estimating the size of a character that is easy to read. “Color blindness” is information that determines what color scheme is difficult to read and what color scheme should be converted. The “document amount to be viewed at one time” is a column for selecting a desired document amount to be displayed at one time on the display screen, and serves as information for determining a minimum character interval and a minimum line interval when displaying a document.

The Web document customization server of the present invention communicates with the accessing user computer, obtains the information entered in the customization application form on the user computer, and stores the user record based on the information. Create and register in the customization information database. FIG. 2 shows an example of the logical structure of the customization information database.

Each user record in this example has a structure in which four items of customization information are represented in data in association with each user ID. The first of the customization items is the minimum number of character points. For example, if "12" is entered in this item, if the Web document to be customized contains characters less than 12 points, The character will be converted to 12 points.

The second item of the customization item is the minimum character interval. If, for example, "12" is entered in this item, a character string having a character interval smaller than 12 points is included in the Web document to be customized. If so, the interval of the character string is changed to an interval of 12 points.

The third item of the customization item is a minimum line interval. If, for example, "24" is entered in this item, the line interval becomes 24 in the Web document to be customized.
If there are two or more lines of characters that are shorter than the point interval, the line intervals of those character strings are changed to 24 point intervals.

The fourth of the customization items is a color change. For example, if "change red / green color to blue / yellow color" is entered in this item, the red color is added to the Web document to be customized. Check if there is a color combination part with the combination of green and green, and if there is such a color part,
Change that part to a combination of blue and yellow.

A user who has registered his / her customization information in this server by using a customization application form can browse various Web documents exhibited by many servers on the Internet and use the Web document customization of the present invention. Access the portal site "Yahoo!" that includes the server function, send the user ID and password in the Web document customization service section, complete the authentication procedure, and then specify the location (URL) of the Web document you want to view. Fill out a predetermined request screen and notify.

The web document customization section of the portal site "Yahoo!" is a customization requester (user).
Sends the URL transmitted from the computer to the Internet, retrieves the relevant Web document from the Web server corresponding to the URL, and temporarily stores it. At the same time, a user record corresponding to the ID of the customization requester is extracted from the customization information database, and the appearance of the temporarily stored Web document to be customized is determined in light of the contents of the four customization items described therein. The document is analyzed to determine whether there is a portion to be customized (a portion to change the description of the markup language) in the document. Then, if there is a portion to be customized based on the request of the client, the portion is changed as in the above-described example to correct the Web document, and the corrected Web document is transmitted to the client computer. Therefore, the Web document is displayed on the browser of the client computer in a format modified by the server.

As described in the above-mentioned Japanese Patent No. 2994351, even if the platform of the client display system is not a standard one,
By combining the present invention with a technology for displaying the Web document as closely as possible to the original format, it is possible to realize the display format desired by the user's personal elements on various display system platforms. Will be possible.

[0020]

As described in detail above, according to the present invention, it is difficult for an elderly person with advanced presbyopia to see small letters, or for a person with color blindness such as color blindness or color weakness to see a specific color scheme. By registering the personal circumstances of the people who want to view the Web document in the Web document customization server, the Web document specified by the client can be corrected according to the request of the client so that it can be easily viewed. Can be delivered to computer. To receive this service, the user (client) must use W in markup language.
There is no need for any technical knowledge on how to write eb documents, nor is it necessary to combine special software with the browser on the user's computer. Moreover,
Rather than uniformly applying the user's customization information registered in the server of the present invention to all Web documents and correcting the same, the original appearance of each Web document is analyzed and the user's customization information is analyzed. It is determined whether or not there is a portion to be applied, and a correction according to the user's desire is added only to the necessary portion, so that a meaningful and detailed service can be provided.
