Semantic Web (the OG “Web 3.0”)

 2022 UPDATE: 

Please note: back in the day, what we used to call Web 3.0 (first use of that term on this blog) was NOT the Crypto stuff, but the Semantic Web. This blog’s use of Web 3.0 refers to the Semantic Web and related paradigms. 

Historically speaking, the first coining of Web 3.0 in conjunction with Semantic Web and/or AI agents and the first coining of  Web 3.0 in conjunction with Wikipedia and/or Google was made in the Wikipedia 3.0: The End of Google? article, which was published on Evolving Trends (this blog) on June 26, ‘06.

June 28, ’06: Here’s what a fellow blogger, who had reviewed the Wikipedia 3.0 article, had to say:

“[…] But there it is. That was then. Now, it seems, the rage is Web 3.0. It all started
with this article here addressing the Semantic Web, the idea that a new organizational
structure for the web ought to be based on concepts that can be interpreted. The idea is
to help computers become learning machines, not just pattern matchers and calculators. […]”

“This is the first non-sarcastic reference to Web 3.0 I’ve seen in the wild”

As of Jan 25, there are 11,000 links to Evolving Trends from blogs, forums and news sites pointing to the Wikipedia 3.0 article.

“In 2004 I with my friend Aleem worked on idea of Semantic Web (as our senior project), and now I have been hearing news of Web 3.0. I decided to work on the idea further in 2005, and may be we could have made a very small scaled 4th generation search engine. Though this has never become reality but now it seems it’s hot time for putting Semantics and AI into web. Reading about Web 3.0 again thrilled me with the idea. [Wikia] has decided to jump into search engines and give Google a tough time :). So I hope may be I get a chance to become part of this Web 3.0 and make information retreival better.”

“Instead of trying to sound smart and discussing the difference between Web 2.0 and 3.0, I will suggest reading this link. Make sure you read the Wikipedia 3.0: The End of Google? article. I like it so much I may print it and put in on the bathroom stall walls at work )

Alexa graph

According to Alexa the Wikipedia 3.0: The End of Google? article estimated penetration peaked on June 28 at a ratio of 650 per each 1,000,000 people. Based on an estimated number of 1,000,000,000 Web users, this means that it reached 650,000 people on June 28, and other hundreds of thousands of people on June 26, 27, 29, 30. This includes people who read the article at about 6,000 sites (according to MSN) that had linked to Evolving Trends. Based on the Alexa graph, we could estimate that the article reach close to 2 million people in the first 4.5 days of its release.

Update on Alexa Statistics (Sep. 18, 2008): some people have pointed out (independently with respect to their own experience) that Alexa’s statistics are skewed and not very reliable. As far as the direct hits to the on this blog they’re in the 200,000 range as of this writing.

Note: the term “Web 3.0″ is the dictionary word “Web” followed by the number “3″, a decimal point and the number “0.” As such, the term itself cannot and should not have any commercial significance in any context.

Update on how the Wikipedia 3.0 vision is spreading:

Update on how Google is attempting to co-opt the Wikipedia 3.0 vision:

Web 3D + Semantic Web + AI as Web 3.0:

Here is the original article that gave birth to the Web 3.0 vision:

3D Web + Semantic Web + AI *

The above mentioned Web 3D + Semantic Web + AI vision which preceded the Wikipeda 3.0 vision received much less attention, which I think is partly because, unlike the Wikipedia 3.0: The End of Google article, this article was not framed in the same controversial manner. This was noted as the biggest flaw of social bookmarking site digg which was used to promote this article.


Feb 5, ‘07: The following external reference concerns the use of rule-based inference engines and ontologies in implementing the Semantic Web + AI vision (aka Web 3.0):

  1. Description Logic Programs: Combining Logic Programs with Description Logic (note: there are better, simpler ways of achieving the same purpose.)

Jan 7, ‘07: The following Evolving Trends post discussing current state of semantic search engines and ways to improve the design:

  1. Designing a Better Web 3.0 Search Engine

The idea described in this article was adopted by Hakia after it was published here, so this article may be considered as prior art.

June 27, ’06: Semantic MediaWiki project, enabling the insertion of semantic annotations (or metadata) into Wikipedia content (This project is now hosted by Wikia, Wikipedia founder Jimmy wales’ private venture, and may benefit Wikia instead of Wikipedia, which is why I see it as a conflict of interest.)


This post provides the history behind use of the term Web 3.0 in the context of the Semantic Web and AI.

This post explains the accidental way in which this article reaching 2 million people in 4 days.
