Abstract

A system includes a mobile device and an optimization server. The mobile device is capable of transmitting request data that includes a requested webpage and identification data. The optimization server is configured to receive response data that corresponds to the request data from a content server, to adapt the response data based on the identification data, and to transmit the adapted response data to the mobile device.

10. The system of claim 1, wherein constructing the adapted webpage involves determining whether the content section exceeds the limitations of the mobile device and breaking the content sections into multiple presentation units if the content section exceeds the limitations of the mobile device, wherein the multiple presentations units are converted into sub-pages for downloading at the mobile device.

11. The system of claim 10, wherein the sub-pages include a main sub-page and any subsequent sub-pages, wherein the main sub-page is initially transmitted to the mobile device for downloading and the sub-pages are cached for future referencing.

12. The system of claim 10, wherein the paginating further comprises enclosing the sub-page with a header or a footer so that the sub-page can link to other sub-pages.

13. The system of claim 1, wherein the transforming involves flattening the first data structure by removing layout imposing markup language tags and transcoding each node.

14. The system of claim 1, wherein the transforming involves preserving the layout by copying grouping and layout tags to the second data structure.

15. The system of claim 1, wherein the transforming involves tab box detecting and preserving the nodes corresponding to the tab box for the second data structure.

17. The method of claim 13, further comprising classifying HTML elements of the first data structure into grouping elements, ignored elements, and simple elements.

18. The method of claim 14, further comprising skipping the creation of the content section if the node is classified as the ignored element, or is an odd-shaped node and is associated with an <

image>

or <

iframe>

tag.

19. The method of claim 14, further comprising creating the content section if the node is classified as a tab box, is a text node and the text is not filler text, is classified as the simple element, or is classified as a grouping element whose geometric features fit within the content section bucket.

20. The method of claim 13, wherein identifying content sections includes comparing geometric properties of a node in the first data structure to one or more content section buckets to determine whether the node and any descendant nodes are a content section.

21. The method of claim 13, wherein the transforming includes form processing so that the form element label corresponds to the form element on a display of the mobile device.

22. The method of claim 13, wherein serializing the second data structure includes breaking the content sections into multiple presentation units if the content section exceeds the limitations of the mobile device, wherein the multiple presentations units are converted into sub-pages for downloading at the mobile device.

23. The method of claim 19, wherein the sub-pages include a main sub-page and any subsequent sub-pages, wherein the main sub-page is initially transmitted to the mobile device for downloading and the sub-pages are cached for future referencing.

24. The method of claim 13, wherein constructing the adapted webpage includes identifying menu content sections by calculating a menu score and if the menu score exceeds a menu threshold, allowing the capability to reorder the menu content section from its current location in a sub-page to a subsequent sub-page.

25. The method of claim 13, wherein constructing the adapted webpage involves determining whether the content section exceeds the limitations of the mobile device and breaking the content sections into multiple presentation units if the content section exceeds the limitations of the mobile device, wherein the multiple presentations units are converted into sub-pages for downloading at the mobile device.

26. The method of claim 22, wherein the sub-pages include a main sub-page and any subsequent sub-pages, wherein the main sub-page is initially transmitted to the mobile device for downloading and the sub-pages are cached for future referencing.
