What is the Semantic Web really all about?
The Semantic Web is based on the relatively straightforward idea that to be able to integrate (link) data on the Web we must have some mechanism for knowing what relationships hold among the data, and how that relates to some “real world” context. The following is a lot of detail that comes from this simple idea. To answer this question properly, let me start back in the early Web era. While I’m going to do some potentially boring personal history, I’ll note the key ideas as I go along. Slogan: A little semantics goes a long way key idea 1: SIMPLE key idea 2: URI-based Another student, Jeff Heflin (now a faculty member at Lehigh) started playing with this idea and extended it to include a rule-based reasoner, a Web scraper for extracting SHOE from non-annotated Web sites, a visual query by example system and a bunch of other things. “Linked Data” (or “Web of Data”) – close to the original vision.
