Just out of curiosity, I did a search on Google Insights for Search (
Google Insights for Search) to see the evolution or trends of usage of the "Web 3.0" versus "semantic web" meme. A couple of interesting facts:
1. Aug. 2006 seems to be the inflection point where both of them started to rise. I connect this to a certain number of articles in the mainstream/general press/media that started to show up right about then. (By the way, I commented about this two posts down).
2. If you look at the overall trend, from 2004 to 2006, while "Web 3.0" held steady/lacked growth, "semantic web" declined slowly but surely. After Aug. 2006, you see a sudden spike in "Web 3.0" and you really see it spiking up steadily, while "semantic web" continues to decline.
3. Interestingly, the first/most recent story associated with "Web 3.0" is a link to the Jupitermedia (who also maintains this blog) press release about the Web 3.0 Conference & Expo in Oct. in Santa Clara.
Two things come to mind: one, that we should really put some "meat" and energy behind using the "web 3.0" meme (as opposed to "semantic web"), and second, I wonder what caused the sudden spike in Aug. 2006?
Very interesting trend indeed. I don't know if there's any one cause for the spike, but I do know that 2006, especially that fall, was a very interesting time for semantic web on the technical front. Several interesting apps/web services for semweb began to spring up in the fall of 2006, and that Spring was the official release of the first SPARQL spec. In addition, Oracle jumped into the Semantic Web game that fall by announcing their triple store.
Also, that was around the time 2.0 reached it's peak, with Myspace and Youtube being purchased, and Facebook hit critical mass, so no doubt that adjacent industry caused a spur of interest in the semantic web.
