Abstract

A system and method for providing transformed web pages to users with special needs is presented. In one aspect of the system and method, a Translator/Mediator Server is located between the user and the web site. The Translator/Mediator Server translates and transforms the web pages that the user requests from the web site. The translation and transformation of the web pages is directed towards the particular needs of the user.

Claims

1. A computer-based method of providing web page content to a user with special needs, where web page content includes mark-up language and all resources to which the markup language refers, the method comprising the steps of:

receiving a web page;

determining whether the received web page has been previously translated;

determining, if it is determined that the received web page has been previously translated, whether the received web page was previously translated for the appropriate special need;

identifying information imparting means within the received web page;

translating those information imparting means which are difficult for the user with special needs to understand into information means which are easier for the user with special needs to understand; and

transmitting the translated web page to the user with special needs.

2. The computer-based method as recited in claim 1, wherein, if it is determined that the received web page has been previously translated, the method further comprises the step of:

determining whether a locally cached version of the received web page is current.

3. The computer-based method as recited in claim 1, wherein the step of identifying information imparting means within the received web page comprises the substeps of:

parsing markup language within the received web page;

downloading all resources to which the markup language refers; and

storing the parsed markup language and the downloaded resources in a locally cached input file.

4. The computer-based method as recited in claim 3, wherein the step of identifying information imparting means within the received web page further comprises the substep of:

identifying components of the stored markup language and downloaded resources which are information imparting means that are difficult for the user with special needs to understand.

5. A system for translating web page content for a user with special needs, where web page content includes mark-up language and all resources to which the markup language refers, the system comprising:

means for receiving a web page;

means for determining whether the received web page was previously translated for the appropriate special need;

means for identifying information imparting means within the received web page;

means for translating those information imparting means which are difficult for the user with special needs to understand into information means which are easier for the user with special needs to understand; and

means for transmitting the translated web page to the user with special needs.

6. The system as recited in claim 5, further comprising:

means for determining whether the received web page has been previously translated.

7. The system as recited in claim 5, further comprising:

means for determining whether a locally cached version of the received web page is current.

8. The system as recited in claim 5, wherein the means for identifying information imparting means within the received web page comprises:

means for parsing markup language within the received web page;

means for downloading all resources to which the markup language refers; and

means for storing the parsed markup language and the downloaded resources in a locally cached input file.

9. The system as recited in claim 8, wherein the means for identifying information imparting means within the received web page further comprises:

means for identifying components of the stored markup language and downloaded resources which are information imparting means that are difficult for the user with special needs to understand.

10. A computer system for translating web page content for a user with special needs, where web page content includes mark-up language and all resources to which the markup language refers, the computer system comprising:

at least one computer-readable memory including;

code that receives a web page;

code that determines whether the received web page was previously translated for the appropriate special need;

code that identifies information imparting means within the received web page;

code that translates those information imparting means which are difficult for the user with special needs to understand into information means which are easier for the user with special needs to understand; and

code that transmits the translated web page to the user with special needs.

11. The computer system as recited in claim 10, wherein the at least one computer-readable memory further comprises:

code that determines whether the received web page has been previously translated.

12. The computer system as recited in claim 10, wherein the at least one computer-readable memory further comprises:

code that determines whether a locally cached version of the received web page is current.

13. The computer system as recited in claim 10, wherein the code that identifies information imparting means within the received web page comprises:

code that parses markup language within the received web page;

code that downloads all resources to which the markup language refers; and

code that stores the parsed markup language and the downloaded resources in a locally cached input file.

14. The computer system as recited in claim 13, wherein the code that identifies information imparting means within the received web page further comprises:

code that identifies components of the stored markup language and downloaded resources which are information imparting means that are difficult for the user with special needs to understand.

15. A computer-based method of providing web page content to a user with special needs, where web page content includes mark-up language and all resources to which the markup language refers, the method comprising the steps of:

receiving a request for a web page;

determining whether the requested web page has been previously translated;

determining, if it is determined that the requested web page has been previously translated, whether the requested web page was previously translated for the appropriate special need;

determining, if it is determined that the requested web page has been previously translated for the appropriate special need, whether a locally cached version of the requested web page is current; and

transmitting, if the locally cached version of the requested web page is current, the locally cached version of the requested web page to the user with special needs.

16. A computer-based method of providing web page content to a user with special needs, where web page content includes mark-up language and all resources to which the markup language refers, the methods comprising the steps of:

identifying information imparting means within the received web page;

determining whether the received web page has been previously translated;

determining, if it is determined that the received web page has been previously translated, whether the received web page was previously translated for the appropriate special need; and

translating those information imparting means which are difficult for the user with special needs to understand into information means which are easier for the user with special needs to understand.
