web3.0

I'm sure someone somewhere is using an XML DB for RDF, but most I've seen are either built on top of RDBMSs or are RDF-native.
Services which do support RDF and/or SPARQL will be able to benefit from the lowering of the integration barrier, and over time increasingly tend to have a commercial advantage over services which don't.

- Success for the Semantic Web wouldn't be improving search, but marginalizing it.
- Take an online train timetable. Right now it'll likely be contained in a database somewhere, exposed through HTML with a form or two.
- perhaps better still a SPARQL endpoint, mashups would be trivial.
- , machine-readable semantics: the link. This page is related to that page. I don't think it's coincidence that the most successful search heuristic to date
- "the best way to find things is not to lose them in the first place".
- Semantic Web languages make it much easier to deal with contexts - which can be expressed directly, without the need for interpreting natural language.

his allows a user to explore connections between different documents, and to see their information organised in a more insightful fashion
But currently very little information available on the web is presented this way. So Twine has to perform this annotation itself. It does this by using a combination of natural language processing and machine learning techniques.
5 more annotations...
- The machine learning process will, over time, allow Twine to learn from user behaviour, Spivack says. Machine learning allows software to refine its understanding of documents. For example, it may ‘learn’ over time that what it thought was the name of a person is in fact the name of a company.
- tools that will allow other websites to upload information to Twine.
- Twine could enable entirely new forms of advertising. "If we understand about your interests we can provide more relevant adverts,"
- 00% relevant, they actually become content not adverts
- there is also a risk of overloading users with new information. "That's a very tough problem," he says.

we are on the verge of ‘reasoning’ computers, and linking this prospect firmly to the vision of a Semantic Web.
Imagine, for instance, being able to ask a computer, ‘Where should I go on holiday?’ and receiving an answer that is as suitable as anything you could have come up with yourself.”
8 more annotations...
- We’re some way off that vision; a vision that the Semantic Web’s biggest advocate, Sir Tim Berners-Lee, recently described as ‘too sci-fi’.
- Linking information in this way is a first step. The next will be to write software that can find and manipulate the data, opening the way to that automated advice on holiday destinations.
- wes much to the ambitions of researchers into Artificial Intelligence during the late 1980’s and 90’s. Is this really what the Semantic Web is about? Personally, I am rather more inclined to subscribe to the Berners-Lee view of this as ‘too sci-fi’ (for now).
- There is certainly scope for harnessing aspects of AI research within the confines of reasonably known and relatively homogenous corporate data sets of the type with which Autonomy currently excels, but out amongst the chaos and vitality of the open Web a less all-encompassing perspective is surely called for.
- The imposition of shared ‘understanding’ such as that required to support the inferences of Artificial Intelligences must surely be impractical.
- crossing some deep political, philosophical and cultural divides.
- In areas such as religion, for instance, the meaning of words is closely tied to a broader world view.
- On the ground, companies are attracting investment and selling products to customers by slowly, steadily, and steadfastly applying semantic technologies that work today.

9 more annotations...
- links to other URIs. so that they can discover
  more things.
- a surprising amount of data
  isn't linked in 2006, because of problems with one or more of the
  steps.
- Breaking them does not destroy
  anything, but misses an opportunity to make data
  interconnected.
- If it doesn't use the universal URI set of symbols, we don't
  call it Semantic Web.
- but the data, if available at all, is buried in a zip archive
  somewhere, rather than being accessible on the web as linked data.
- There is also a large and increasing amount of URIs of
  non-ontology data which can be looked up.
- This
  means that I can write in my FOAF file that I know Håkon Lie
  by using his URI in the Opera Community data, and a person or machine
  browsing that data can then follow that link and find all his friends.
- only his friends who are in the Opera Community.
- to make links elsewhere, is
  necessary to connect the data we have into a web, a serious, unbounded
  web in which one can find al kinds of things,

Sir Tim Berners-Lee: Semantic Web is open for business | The Semantic Web | ZDNet.com

web3.0

Asked about an important article in Scientific American from 2001, Berners-Lee was quick to move past the grand vision outlined there, and to stress the importance of simple yet empowering steps;

“In fact, the gain from the Semantic Web comes much before that. So maybe we should have written about enterprise and intra-enterprise data integration and scientific data integration. So, I think, data integration is the name of the game. That’s happening, it’s showing benefits. Public data as well; public data is happening and it is providing the fodder for all kinds of mashups.

What we should realize is that the return on investment will come much earlier when we just have got this interoperable data that we can query over.”
data holders will gain benefits

- ‘oh, the Semantic Web is going to involve us all going to our HTML pages and marking them up to put semantics in them.’ Now, there’s an important thread there, but to my mind, it’s actually a very minor part of it. Because I’m not going to hold my breath while other people put semantics in by hand… So, where is the data going to come from? It’s already there. It’s in databases…”
- So, some data is scraped from HTML pages, some of it is pulled out of databases, some of it comes from projects which have been in XML.
- growth in the availability of data from less philanthropic sources, there is a clear need for greater clarity with respect to the ‘proper’ use and reuse of data
- to those sites receiving such criticism for their rather different perspective at the moment, the social networks.
- they hoard this data. The business model appears to be, ‘We get the users to give us data and we reuse it to our benefit. We get the extra value.’”
  
  …
- Web 2.0 is a stovepipe system. It’s a set of stovepipes where each site has got its data and it’s not sharing it.
- “People can indeed choose not to go to that site [if it does not open access to their data]”
  
  In other words, in a market such as the one in which we operate, there is always scope for new entrants

minimal annotation in the content to help top-down tools interpret it
These days only companies have web sites, individuals
have blogs and social network profiles. There is a great opportunity to standardize and structure the information because blogs
and profiles are based on templates.
5 more annotations...
- it would also be helpful if widgets were
  wrapped into standard enclosures. A simple widget tag can go a long way
- major newspapers would follow as well.
- there needs to be more and better integration of
  microformats into the blogging platforms
- they do not cover the basic range of things that people discuss on the web - books, music,
  movies, recipes, and restaurants are all noticibly absent
- allow a large subset of the web - the blogosphere - to become quite structured.

Mozilla Does Microformats: Firefox 3 as Information Broker - ReadWriteWeb

www.readwriteweb.com/...does_microformats_firefox3.php - Preview

web3.0

Much in the same way that operating systems currently associate particular file types
with specific applications, future Web browsers are likely going to associate
semantically marked up data you encounter on the Web with specific applications, either
on your system or online. This means the contact information you see on a Web site
will be associated with your favorite contacts application,
If Mozilla proceeds with this goal for Firefox 3 to be a broker of information, then
that will significantly raise the stakes in the browser war again.

he heavy lifting is done by the combination of a natural language processing
engine and a massive hard coded, learning database that Clear Forest has built.
9 more annotations...
- appears
  that the API requires an XML document, where the main text is marked differently from the header and footer.
- to build intelligent search engines that look for related content
- By automatically identifying entities in the document, Calais also identifies
  what should be linked.
- structured alerts. Modern alert systems are keyword based and suffer from false positives
- Semantic technologies result in
  better, faster, more precise and relevant information, and Reuters, as a big player in the information
  space, wants to be one of the first companies delivering this kind of experience.
- a growing semantic database of people, places, companies and events. With each new document submitted
  into Calais the database gets richer and more complete.
- advantage of having an open API is training the system
- engineers
  to run into cases that they have not thought about and broaden the capabilities of the system.
- natural language processing, AI techniques, and a massive databases

web3.0

You hand the web service unstructured text (like news articles, blog postings, your term paper, etc) and it returns semantic metadata in RDF format.
the Calais web service looks inside your text and locates the entities (people, places, products, etc), facts (John Doe works for Acme Corp) and events (Jane Doe was appointed as a Board member of Acme Corp) in the text. Calais then processes the entities, facts and events extracted from the text and returns them to the caller in RDF format.
