When Google crawls the Web, it extracts facts from content on the pages it finds as well as links on pages. How much information does it extract about facts on the Web? Microsoft showed off an object-based search about 10 years ago, in the paper, Object-Level Ranking: Bringing Order to Web Objects..
The team from Microsoft Research Asia tells us in that paper:
Existing Web search engines generally treat a whole Web page as the unit for retrieval and consuming. However, there are various kinds of objects embedded in the static Web pages or Web databases. Typical objects are products, people, papers, organizations, etc. We can imagine that if these objects can be extracted and integrated from the Web, powerful object-level search engines can be built to meet users’ information needs more precisely, especially for some specific domains.
