Small form factor web browsing

摘要

A large web page is analyzed and partitioned into smaller sub-pages so that a user can navigate the web page on a small form factor device. The user can browse the sub-pages to find and read information in the content of the large web page. The partitioning can be performed at a web server, an edge server, at the small form factor device, or can be distributed across one or more such devices. The analysis leverages design habits of a web page author to extract a representation structure of an authored web page. The extracted representation structure includes high level structure using several markup language tag selection rules and low level structure using visual boundary detection in which visual units of the low level structure are provided by clustering markup language tags. User viewing habits can be learned to display favorite parts of a web page.

主权项

1. A computer to adapt web content for display on a small form factor device having a display screen with a width, the computer comprising:
a high level structure analysis module executed on one or more processors to receive a web page and to analyze a markup language tag tree of a markup language document representing the web page to identify:
peripheral regions of the web page including a header, a footer, a left, and a right regions; andbody regions enclosed by the peripheral regions; a low level structure analysis module executed on the one or more processors to analyze the markup language tag tree defining the peripheral regions and the body regions to:
identify visual boundaries from analyzing properties of tags of the markup language tag tree;detect patterns in leaf markup language tags to find one or more basic semantic units each having a shape;project the shape of each basic semantic unit normal to perpendicular axes; andidentify the visual boundaries of the web page based on projection values for each axis.
