VIPS, or Vision-Based Page Segmentation is providing alternatives to searching the web. VIPS breaks down the layout and visual representation on a webpage to derive semantic meaning used in searching web content.
MIT Technology Review<i>Researchers from the University of Chicago and Microsoft Research Asia have devised a system that analyzes Web content at the level of blocks of information on a page rather than coarser page-level. This allows for a model of the relationships between Web pages that shows the intrinsic semantic structure of the Web. The method could lead to more accurate search engines, according to the researchers.
This could be a direction I consider as I bring together the area of digital representation and Identity.
