Ostracus writes "The next big stage in the evolution of the Internet, according to many experts and luminaries, will be the advent of the Semantic Web — that is, technologies that let computers process the meaning of Web pages instead of simply downloading or serving them up blindly. Microsoft's acquisition of the semantic search engine Powerset earlier this year shows faith in this vision. But thus far, little Semantic Web technology has been available to the general public. That's why many eyes will be on Twine, a Web organizer based on semantic technology that launches publicly today."

The Story of the Semantic Web--Slashdot Style! (Score:5, Interesting)
But that was the long long ago, so let's fast forward a few years. When its future looked most bleak, Sir Tim (who can summon fire and explosions at will) told us what to expect [slashdot.org]
Then a few years passed and nothing.
Until the 2006 World Wide Web conference made us suspicious of the Semantic Web [slashdot.org]. We spread rumors about the Semantic Web and told all the cooler technologies that the Semantic Web was just out to rape our privacy. So we challenged the Semantic Web [slashdot.org]. And claimed it would fail [slashdot.org].
Just when I was expecting Sir Tim to get underneath a blanket & release a sobbing YouTube video of everyone being bastards for attacking The Semantic Web right when she was going through really tough times and that we should all just leave her alone

First off, that was brilliant.

My problem is simply this: Assuming a "semantic web" existed right here and now, how would I use it? Google I can understand: Go there, fill in the blank with whatever I can think of, hit "Search" and hope for the best.
Trying to get a computer to understand the meaning of a web page is, fundamentally, getting machines to do my thinking for me. In my experience, they're pretty bad at it.
And that's not even considering sites with political spin; how would a machine work out the meaning there? Someone's going to say it's wrong, and if that someone is the user performing the search, then the semantic search is going to take the blame.
This will also lead to "Semantic Engine Optimizers" figuring out how to polish turd websites into something that even shows up, which makes the semantic web less useful. About as useful as, say, Google is now.
The "Semantic Web" to me is like the future: everyone has their own idea of how it will be, and the reality will disappoint them. Ideas are cheap, and at this point, nobody should care unless they're actually going to make something out of them.
When a semantic search engine ships that is actually useful, let me know. Until then, I'll stick with the best semantic search engine I've ever seen: the people I know.

They're pretty bad at it NOW, personally I think the web would get infinitely better if all user tastes and profiles were congregated, as they are at delicious, so people with similar interests are pointed to the results found by others. That's one thing I like about delicious, you can browse the bookmarks of others who have "done the th

I don't think the computers are supposed to do the thinking for us. My understanding of the Semantic Web is an attempt by humans to encode meaning into the markup.
I'll believe it works when I can finally do a search on a keyword like "digicam" and choose an option to exclude any website that is trying to sell me something.

I worked, in a research capacity, on technologies for building the semantic web for a while and to be quite honest with you I can't see how it could ever work in the real world. Just in the department I was in there must have been a dozen different ideas for how to build a semantic web and the only thing that tied them all together was the fact that they all relied on humans doing a lot of work to tell a computer what the content was about.
I'm sure that some of this semantic web technology will be useful somewhere but it's not going to take the world by storm simply because it doesn't work well enough and it requires too much up front effort for possibly / probably no gain.
The only way I can really see it working is if we can develop AI to the point where it can actually understand what it is reading without a human having to first develop some huge ontology and join the dots for it. But that's just my opinion.

This about sums up my experience with it as well.
First we started off with categories, and tags in our searches. Then we switched to no-searching, but a filter-based tree mechanism for reducing the number of hits - instead of a table of contents. Then we switched to a table of contents using "task", "product" +4 other tree 'heads'. Then they started mulling over per-sentence tagging. It kept ballooning because it was obvious that though we had all these tags and a hierarchy and divisions, it didn't help - our customers used google to search for our help doc rather than our internal systems/help application.
In the end, they decided that they needed to automatically categorize everything. I tried to point out the futility of it, and what that would get them, but no one really wanted to listen. They were very surprised in the end when they got a search engine that looked for keywords.
Exactly what the help system they started with already did.
The two biggest problems with semantic-anything is
1) it doesn't provide any additional value without an exponentially increasing order level of (human) effort,
and
2) Unless someone comes up with a single, agreed upon, final, categorization (an ontology) - your markup will always disagree with someone elses, except for the most simple things that would be noted by search engines looking for keywords.
When I left, the project had been ongoing for 3 years, and they still didn't know what they wanted it to do - they were still searching for purpose and changing the target every day. ... we didn't share an office, did we?

Computers are getting closer [slashdot.org] and can "understand" some basic phrases and grammar, but on the whole remain mostly useless because of everything they miss. I think semantic internet implementations are possible, but the reason it hasn't changed anyone's life is that it's still a long ways off.

Baby steps (Score:4, Insightful)
Twine seems to be just a generic contextual search engine, as opposed to a pure keyword search engine. While it's a step, it's a very tiny step.
What I want to see is more about the correlation between topics. For example, if I'm looking into PHP templating and search twine [twine.com], I get a few people's bookmarks on the topic. Nothing especially useful, and definitely nothing I couldn't find elsewhere. With real semantics I'd want to see a list of various templating engines, pro and con articles grouped for each, and maybe other sections on related design patterns and frameworks.
In other words, I want to see semantics. Context search isn't going to make anyone turn their head.

Not really. That wikipedia page was not written by a computer. So it has nothing to do with the semantic web where pages are connected with some form of computer "understanding". Those are humans documenting the semantics, not computers interpreting them.
Social networking links still have no "understanding" for the computer. They just tell you what your friends like, not what they mean.
The only semantics on the web today are human input with no innovative output.

All the semantic web gives you is the ability to layer a logical design over data. It's like a database design, except it's "open world", meaning there can be many different designs, it's up to the agent to pick the one it trusts, and it can't really make assumptions based on what it doesn't know.
The only inferences made are those that have been imagined by some human designer. And they might be very wrong , if the designer was wrong.
The "kinds" of inferences available are also pretty limited, like hierar
Proper data first, then cool applications (Score:2, Insightful)
In a nutshell, the goal of the Semantic Web is to bring knowledge representation to the Web (using graphs, networks, binary predicates, however you want to call it).
I've been trying to apply data from the Semantic Web for a few years now.
I can see two roadblocks to mainstream adoption:
* Web data is immensely scruffy. If thousands of people contribute to a dataset without any restrictions, you get a mess (e.g. multiple URIs used to denote the same class or individual, which results in fractured data)
