Abstract

A method for identifying elements of a webpage is provided. The method includes accessing, by an electronic device, a document object model (DOM) of the webpage. Changes applied to properties of a plurality of elements of the webpage across different media queries for different viewports are then analyzed using the DOM. The different viewports are of different sizes. Based on analyzing, ranking score is determined for each element. Elements having ranking score greater than a predefined threshold are identified as representative elements of the webpage.

Claims

1. A method comprising:

accessing, by an electronic device, a document object model (DOM) of a webpage;

analyzing, using the DOM, changes applied to properties of a plurality of elements of the webpage across different media queries for different viewports to determine ranking score for each element, wherein the different viewports are of different sizes; and

identifying at least one element that has a ranking score greater than a predefined threshold as a representative element of the webpage.

2. The method as claimed in claim 1 and further comprising at least one of:

extracting keywords from the at least one element as keywords representative of the webpage;

advertising on the webpage based on the at least one element;

generating summary of the webpage; and

providing recommendation based on the at least one element.

3. The method as claimed in claim 1, where in the properties of a first element of the plurality of elements comprise at least one of:

visibility of the first element across different viewports;

size of the first element across different viewports; and

position of the first element across different viewports.

4. The method as claimed in claim 1, wherein analyzing comprises assigning one or more ranking scores to the plurality of elements.

5. The method as claimed in claim 4 and further comprising altering the one or more ranking scores of the plurality of elements based on analyzing.

6. The method as claimed in claim 5, wherein altering the one or more ranking scores comprises at least one of:

decreasing a ranking score of a first element if the first element is visible in a first viewport and invisible in a second viewport, wherein size of the second viewport is smaller than size of the first viewport;

increasing the ranking score of the first element if size of the first element is larger in the second viewport than that in the first viewport, wherein size of the second viewport is smaller than size of the first viewport; and

increasing the ranking score of the first element if position of the first element in sorted document object model of the first viewport is higher than that in sorted document object model of the second viewport, wherein size of the second viewport is smaller than size of the first viewport.

7. The method as claimed in claim 1, wherein the electronic device is at least one of a client device or a server, and the properties comprise Cascading Style Sheets (CSS) properties.

8. A method comprising:

accessing, by an electronic device, a document object model (DOM) of a webpage;

assigning one or more ranking scores to a plurality of elements of the webpage;

determining, using the DOM, changes applied to properties of a plurality of elements of the webpage for different viewports, wherein the different viewports are of different sizes;

altering the one or more ranking scores of the plurality of elements based on the analyzing; and

identifying at least one element, having ranking score greater than a predefined threshold, as a representative of the webpage.

9. The method as claimed in claim 8, wherein determining the changes comprises analyzing Cascading Style Sheets (CSS) properties of the plurality of elements across different media queries for different viewports.

10. The method as claimed in claim 8, where in the properties of a first element of the plurality of elements comprise at least one of:

visibility of the first element across different viewports;

size of the first element across different viewports; and

position of the first element across different viewports.

11. The method as claimed in claim 10, wherein determining the changes applied to the properties comprises at least one of:

determining the first element to be visible in a first viewport and invisible in a second viewport;

determining the size of the first element to be different in the first viewport than in the second viewport; and

determining the position of the first element to be different in the first viewport than in the second viewport.

12. The method as claimed in claim 10, wherein altering the one or more ranking scores of the plurality of elements comprises at least one of:

decreasing a ranking score of the first element if the first element is visible in a first viewport and invisible in a second viewport, wherein size of the second viewport is smaller than size of the first viewport;

increasing the ranking score of the first element if size of the first element is larger in the second viewport than that in the first viewport, wherein size of the second viewport is smaller than size of the first viewport; and

increasing the ranking score of the first element if position of the first element in sorted document object model of the first viewport is higher than that in sorted document object model of the second viewport, wherein size of the second viewport is smaller than size of the first viewport.

13. The method as claimed in claim 10, wherein altering the one or more ranking scores of the plurality of elements comprises:

providing a higher ranking score to the first element if the size of the first element in the first viewport is larger than size of a second element in the first viewport and similar changes are applied to Cascading Style Sheets (CSS) float property of the first element and of the second element in a second viewport as against the first viewport.

14. The method as claimed in claim 10, wherein altering the one or more ranking scores of the plurality of elements comprises:

providing a higher ranking score to the first element if position of the first element in a sorted document object model of a first viewport is lower than position of the second element in the sorted document object model of the first viewport.

15. A non-transient computer readable medium for storing computer instructions that when executed by at least one processor causes the at least one processor to perform a method for identifying element of a webpage, the computer instructions comprising:

accessing a document object model (DOM) of a webpage;

analyzing, using the DOM, changes applied to properties of a plurality of elements of the webpage across different media queries for different viewports to determine ranking score for each element, wherein the different viewports are of different sizes; and

identifying at least one element that has a ranking score greater than a predefined threshold as a representative element of the webpage.

16. The computer readable medium as claimed in claim 15 and further comprising at least one of:

extracting keywords from the at least one element as keywords representative of the webpage;

advertising on the webpage based on the at least one element;

generating summary of the webpage; and

providing recommendation based on the at least one element.

17. The computer readable medium as claimed in claim 15, wherein analyzing comprises assigning one or more ranking scores to the plurality of elements.

18. The computer readable medium as claimed in claim 17 and further comprising altering the one or more ranking scores of the plurality of elements based on analyzing.

19. The computer readable medium as claimed in claim 18, wherein altering the one or more ranking scores comprises at least one of:

decreasing a ranking score of a first element if the first element is visible in a first viewport and invisible in a second viewport, wherein size of the second viewport is smaller than size of the first viewport;

increasing the ranking score of the first element if size of the first element is larger in the second viewport than that in the first viewport, wherein size of the second viewport is smaller than size of the first viewport; and

increasing the ranking score of the first element if position of the first element in sorted document object model of the first viewport is higher than that in sorted document object model of the second viewport, wherein size of the second viewport is smaller than size of the first viewport.

20. The computer readable medium as claimed in claim 15, wherein the electronic device is at least one of a client device or a server, and the properties comprise Cascading Style Sheets (CSS) properties.
