Maybe a smart pre-emptive strike against twitters annotations?

I have no idea what you mean by this. Twitter is not trying to become a database or Wikipedia. Tweets are short communications and signalling, which they want to enrich with more data for specialized applications.

The problem with the semantic web is you need a universal ontology. i.e. you need everyone to agree on the same thing. Cory Doctorow's Metacrap explains more http://www.well.com/~doctorow/metacrap.htm

That's a strawman. You in fact don't need a "universal ontology," you just need people to agree on first principles (e.g. URLs are unique, there are things called triples, etc.)

Yes. Absolutely correct. I worked at a semweb company for years, it's all about making a small functional ontology for a particular purpose.

Of course, that leads to the question : is that ontology actually relevant or is it just important that the data is structured?

This is huge for many reasons, but namely, this could finally lead to the "semantic web." Metaweb's video, which is linked to in the article, explains part of the "how". The problem with the semantic web is that many need to embrace it. Many people need to tag text with these "bar codes" (uniquely identified entities). That can take a big effort and there has to be a ROI for this big undertaking. The other is that th…

Many people need to tag text with these "bar codes" (uniquely identified entities).

This sort of thinking seems to be common in people who like the idea of the semantic Web but who are pessimistic about its implementation. I'm not sure it's going to be the case.

As we've seen happen with other technologies, I suspect we'll see a MetaWeb style approach of "deriving the barcodes" from existing and unformatted content. This will not be a 100% accurate process, but will be "good enough" to make the semantic Web a realistic and large scale underpinning to the next generation of search systems.

Deriving the ontology potentially has more value because it can help avoid spammers. If anyone can just assert that their content is of a specific type without any kind of verification, we end up with the meta tag keywords attribute all over again, where none of that data is trust-able.

I think you do need a universal ontology if you want to make the kind of progress the semantic web people talk about. If you just have a bunch of small, separately created ontologies, the situation can indeed seem great until each expands. Then the intersections and ambiguities become huge.

Sure, if you weren't concerned exactness and lack of ambiguity, you could expand the world of triples into a giant, poorly organized collection of information. It would be kind of like the web. The approach "works" but we, uh, already have the web.

Also, the Doctorow document excellent. Anyone expected naive metadata to be extensible should have a reply to it.

Inferencing solves this problem.

Are there anyone here that downloaded and played with their data set (PG dump). I have fiddled with one of their table to process their Wikipedia data. I think Google bought it for their supposedly wicked-fast GraphDB.

I haven't downloaded the data set for the fact that it doesn't look like the accompanying MQL server is available for download. Am I correct on this? MQL is sweet (e.g. give me all of Tom Cruise's movies since 1995 that have cost over 10million dollars to make), but what good is the data dump if all I can do is resort to simplistic SQL queries? MQL support is just as important as the data itself. I'm sure that I'm ov…

AFAIK you need to process that data - put it into a graph db or a RDF store. SQL/MQL/RDF/OWL are all just query languages that can query the data. BTW there is no open source MQL implementation.

I think even small agreed upon ontologies in different areas would be a big step up from the virtually none that we have. Current services like the experimental google squared currently have nothing to work with. Even a complicated mesh of partially interlinking ontologies would be better.

What about Facebook's new metadata? What are people in the semantic web area saying about that?
