Abstract

A method and system for displaying web content on a device including the functionalities of requesting a web page by a user, in response to a user request, downloading the web page to a server, searching for at least one template for the web page on a database of the server, if a template is found for the web page, effecting best matching between the template and a plurality of information bearing regions on the web page and importing the plurality of information bearing regions to at least one device adapted page.

Claims

1. A method for displaying web content on a device comprising:

requesting a web page by a user;

in response to a user request, downloading said web page to a server;

searching for at least one template for said web page on a database of said server;

if a template is found for said web page, effecting best matching between said template and a plurality of information bearing regions on said web page; and

importing said plurality of information bearing regions to at least one device adapted page.

2. A method for displaying web content on a mobile communicator according to claim 1 and wherein template includes matching assist instructions.

6. A method of obtaining information from at least one dynamic website according to claim 1 and wherein said employing said at least one template to extract information from at least one web page of said at least one dynamic website when at least one of said at least one web page is in a second state, different from said first state, comprises effecting best matching between said at least one template and document object models (DOMs) of said at least one web page in a second state.

9. A method for obtaining information from at least one dynamic website according to claim 1 and also comprising maintaining login information of users in a database in the form of cookies and when a user again requests said web page, said login information of the user is retrieved and a personalized web page is displayed to the user.

10. A method for obtaining information from at least one dynamic website according to claim 1 and also comprising converting a web page received from the Internet into a tree representation of the DOM. and subsequently matching said web page to a suitable template, in order to generate an adapted web page for display on said mobile communicator.

11. A method for obtaining information from at least one dynamic website according to claim 10 and wherein in order to find a template suitable for said web page, all the templates having a scope including the requested web page are found and a distance between the tree representation of the web page and the tree representations of each of the web pages used to create the templates is calculated, using a tree comparison algorithm.

12. A method for obtaining information from at least one dynamic website according to claim 11 and wherein if said distance between the tree representation of the web page and the tree representation of a given template is below a predetermined threshold, that template is used for adapting said web page for display on a mobile communicator.

3. A method of obtaining information from at least one dynamic website, the method comprising:

constructing at least one template of at least a part of a web page of said at least one website when said web page is in a first state; and

employing said at least one template to extract information from at least one web page of said at least one dynamic website when at least one of said at least one web page is in a second state, different from said first state.

4. A method of obtaining information from at least one dynamic website according to claim 3 and wherein said at least one template is based on a document object model (DOM).

5. A method of obtaining information from at least one dynamic website according to claim 3 and wherein said at least one template comprises at least one cell-based element of said web page.

7. A method of obtaining information from at least one dynamic website, the method comprising:

obtaining at least one document object model (DOM) of a web page of said at least one dynamic website when said web page is in a first state; and

employing said at least one document object model (DOM) to obtain information from at least one web page of said at least one dynamic website when at least one of said at least one web page is in a second state, different from said first state.

8. A method of obtaining information from at least one dynamic website according to claim 7 wherein said employing said at least one document object model (DOM) to extract information from at least one web page of said at least one dynamic website when at least one of said at least one web page is in a second state, different from said first state, comprises effecting best matching between said at least one document object model (DOM) and document object models (DOMs) of said at least one web page in a second state.

13. A system for displaying web content on a device comprising a computer programmed to support at least the following functionality:

requesting a web page by a user;

in response to a user request, downloading said web page to a server;

searching for at least one template for said web page on a database of said server;

if a template is found for said web page, effecting best matching between said template and a plurality of information bearing regions on said web page; and

importing said plurality of information bearing regions to at least one device adapted page.

14. A system for displaying web content on a mobile communicator according to claim 13 and wherein template includes matching assist instructions.

18. A system for obtaining information from at least one dynamic website according to claim 13 wherein said employing functionality said at least one template to extract information from at least one web page of said at least one dynamic website when at least one of said at least one web page is in a second state, different from said first state, employs best matching between said at least one template and document object models (DOMs) of said at least one web page in a second state.

21. A system for obtaining information from at least one dynamic website according to claim 13 and also comprising a database in which login information of users is maintained in the form of cookies and wherein when a user again requests said web page, said login information of the user is retrieved from the database and a personalized web page is displayed to the user.

22. A system for obtaining information from at least one dynamic website according to claim 13 and wherein said computer is operative to convert a web page received from the Internet into a tree representation of the DOM. and subsequently to match said web page to a suitable template, in order to generate an adapted web page for display on said mobile communicator.

23. A system for obtaining information from at least one dynamic website according to claim 22 and wherein said computer is operative, in order to find a template suitable for said web page, to find all the templates having a scope including the requested web page and to calculate a distance between the tree representation of the web page and the tree representations of each of the templates, using a tree comparison algorithm.

24. A system for obtaining information from at least one dynamic website according to claim 22 and wherein if said distance between the tree representation of the web page and the tree representation of a given template is below a predetermined threshold, that template is used for adapting said web page for display on a mobile communicator.
