Hi all,

Just letting you all know that this months Semantic Web Gang podcast for October 2008 was released today. It’s available on the The Semantic Web Gang blog as a post titled “October 2008: The Semantic Web Gang discusses the launch of Twine“. It is in fact about the recent public release of the Twine.com system by Radar Networks.

Plus, we’ve got Nova Spivack (the CEO of Radar/Twine) and Jim Wissner (the Chief Architect of Twine) on the call!

It’s great. I am on the call, I didn’t say much on the call particularly as just as I was about to ask a question someone else usually piped up just before me and asked a question (often the same question!). I appear at the start and the end of the recording though.

The central thing that I am interested in is actually still under the hood of Twine. I’m incredibly interested by the progression of the recommendation algorithms, particularly through modern techniques. I’m also interested in their automatic editing. It’s very exciting, and I do have a feeling that the public release that you see today isn’t the entirety of twine.

It was lovely to speak to Nova and Jim, and the rest of the gang. There should be another episode later this month :-)

Enjoy!

Daniel

Intelligent Agents and the Semantic Web

One of my (independent) articles has been published as a feature article on the IBM developerWorks website. It is “Intelligent Agents and the Semantic Web“. Not only that, but they also published a podcast episode with me. Have a read, the examples are in Java, but all the theory applies to any programming language and agent library.

What? “Semantic” Web, “Linked” Data and Web “3.0″? What are they?!!!?

Today (Tuesday 28th October 2008), I gave a seminar/discussion of the new web-based buzzwords, and explained that terms like Semantic Web, Linked Data and Web 3.0 aren’t marketing nonsense but very well defined techniques and technologies. The seminar went really well, and the ideas were well received.

In fact, you can have a look at the “iPaper” version of the slides , thanks to my academia.edu account.

New main website design

I’ve got a brand new combine harvester…. well, actually a new main website design which explains what I do, what I’m interested in… and gives a lot more info than my old one did. Go have a look at vanirsystems.com.

linkeddata, semweb @ 16 September 2008, “No Comments”

Good news for the Linked Data community comes from Berlin student Christian Becker, who provides us with information about BBC Interlinking with DBPedia:


commissioned to create links between DBpedia and an internal BBC vocabulary, which enable the BBC to use DBpedia/Wikipedia as a

controlled vocabulary

Keep up the good work Christian!

Yeah, you heard me right:

Linked Data is more important than the Large Hadron Collider

My points:

  • I feel that the Large Hadron Collider is a bit of a waste of time, money and a big waste of energy (think of all the carbon emissions!).
    • Why do we need to know the very very smallest parts of things?
    • Why do we need to know what happened microseconds after the big bang?
    • Why not just analyse what happened if the Higgs Boson was and wasn’t found (every possible aspect)?
    • Face it: It’s not going to cure Cancer, or prevent HIV
    • Face it: we’re still going to be here whether or not the Large Hadron Collider was successful
  • Linked Data on the other hand is incredibly important
    • Everything in real life (conceptual/abstract and objective/physical) is interconnected with everything else
    • We have a lot of data about everything, but it’s not interconnected
    • Linked Data allows for the interconnectedness of data, and therefore true computation modelling of everything. Which then allows for a real and useful insight into scientific (and artistic and historic) data!
    • Just imagine a world where you can easily browse through the history of the atom, and then delve into the science found on the atom, and then go deeper into the subatomic level, and then browse back out into the historic realm, finding out about experiments that happened and whether it had any impact on society.
    • Thanks to Linked Data:
      • a lot of problems can be solved before they arise
      • new areas of research can be formed
      • “recreating the wheel” can be prevented
      • a really interesting browsing experience can be achieved

So there we go. That is why Linked Data is more important than the Large Hadron Collider….

Sorry to the physics-geeks, but maybe you can gain something useful from Linked Data if you aren’t already. I know that some Chemistry and Physics people already have some Semantic Web / Linked Data research & development going on, and hey Tim Berners-Lee did start the Web project at CERN.

I fear that a lot of people within science and even computer science forget to look at things with Holistic eyes, as a lot of science and mathematics is incredibly Reductionist.

Kingsley Idehen made an interesting blog post recently in a question and answer format (see his blog post: “The future of the desktop“), so i’ve decided to provide my own answers:

Q: Is the desktop of the future going to just be a web-hosted version of the same old-fashioned desktop metaphors we have today?

A: In terms of becoming web-based the desktop as we know it will not change much at the very surface level. I doubt that a web-hosted version of the old-fashioned Operating System would ever be stable enough (some of you will know if you’ve ever used a “

dumb-terminal“). The Operating System, however, is likely to become more and more web-aware; taking up more and more of the challenge of “Web Universal Plug and Play”.

Q: The desktop of the future is going to be a hosted web service

A: False. I think it’ll be totally the inverse, I’m even inclined to say that everybody would host their own space which is interconnected with other services across the web…. it won’t be a “hosted web service”.

Q: The Browser is Going to Swallow Up the Desktop

A: Interestingly this is where Microsoft were heading in the right direction… the file system explorer was also the internet explorer, just by changing the location in the address bar you were capable of switching from file mode to web mode. (takes quite a lot for me to admit that). If you have a fully integrated system then you can take full advantage of everything. The web of documents, is a web of documents…. what are file systems good at manipulating… documents (and also viewing metadata)! So is the browser going to swallow up the desktop? No… it already has.

Q: The focus of the desktop will shift from information to attention

A: No information is vital…. attention will become an interesting part of search, but it’s actually has to maximise utilisation of information (aka knowledge) in order to do it’s best (just as any other program needs to do). This effects both desktop systems and browser systems.

Q: Users are going to shift from acting as librarians to acting as daytraders

A: People are always going to categorise things, and other people will always want things categorised. How can you expect someone to trawl through their bookmarks without them being categorised? However, things will become more automised when interlinked with other interlinked data…. therefore users are likely to become Personalised Knowledge Managers controlling what knowledge they possess and how they want their intelligent agents to deal with it.

Q: The Webtop will be more social and will leverage and integrate collective intelligence

A: OK, first off… really bad terminology usage going on here. Webtop? That’s a bad name… and for something which I don’t think will become widespread. Also collective intelligence is actually about agents having specific knowledge. The web-aware desktop will slowly include more and more agent technology (see some of the Apple/Xerox work on Intelligent Agents and Intelligent User Interfaces done in the late 80s and early 90s) and will certainly encorporate

Linked Data technologies (see the Semantic Desktop and OpenLink Data Spaces).

Q: The desktop of the future is going to have powerful semantic search and social search capabilities built-in

A: Yes, I’ve mentioned this in most of my answers above.

Q: Interactive shared spaces will replace folders

A: I agree with Kingsley when he says “Data Spaces and their URIs (Data Source Names) replace everything. You simply choose the exploration metaphor that best suits you space interaction needs”… there is nothing more to say than that…. a URI is the key to a data space, a data space is where your data objects are stored which also have their own URIs.

Q: The Portable Desktop

A:The portable desktop (or ubiquitous desktop) will emerge as a mobilisation of a Linked Data desktop…. all depends on hardware at the moment. This will go beyond mobile phones, mobile computers (such as the Asus EEE) and PDA’s.

Q: The Smart Desktop

A: Yes, this is what I’ve been discussing.

Q: Federated, open policies and permissions

A: Have we not got the technologies for these points already :-)

Q: The personal cloud

A: Can’t add anything more to Kingsley’s point “

Personal Data Spaces plugged into Clouds (Intranet, Extranet, Internet).”

Q: The WebOS

A: There are some interesting implementations of the WebOS idea out there, and a few years I was actually considering building one using Ruby On Rails and AJAX….. really we don’t need to focus on this right now, it’s more about interlinking things (aka Linked Data)

Q: Who is most likely to own the future desktop?

A: I have nothing more to add to Kingsley’s comment: “You! And all you need is a

URI (an ID or Data Source Name for “Entity You”) and a Profile Page (a place where “Entity You” is Describe by You).”

SemanticBible Linked Data: Version Alpha 1

I am very very pleased to announce something which I have been working on for a while which is the transformation of SemanticBible into Linked Data. Please be aware that this a very early version at the moment, and so if you see it break when you are looking around then I’m probably improving and enhancing it.

More information (and recent update information) is available on the Linked Data SemanticBible about page. But here’s a quote from it for you:

SemanticBible is an online Semantic Web version of the Bible, it has lots of facts and figures about the Christian sacred texts. Please do have a browse around.

A Brief History

SemanticBible started life as a project by Sean Boisen over at SemanticBible.com, but Daniel Lewis and his colleagues at OpenLink Software decided to help Sean out by providing a Linked Data based approach. The outcome was this service.

Starting URIs:

  • http://semanticbible.openlinksw.com/bible/cgi : The Composite Gospel : holds information about the stories in the Gospels
  • http://semanticbible.openlinksw.com/bible/NTIndividuals :New Testament Individuals : holds information about people and places referenced in the New Testament
  • http://semanticbible.openlinksw.com/ontology/cgi : The Composite Gospel Ontology : the vocabulary for describing the stories in the Gospel
  • http://semanticbible.openlinksw.com/ontology/NTNames : The New Testament Names Ontology : The vocabulary for describing the people and places referenced in the New Testament

As I said before, do expect it to break randomly…. but if it seems like theres something not quite right, or if you have any feature requests that you wish to add then do email my work email ( dlewis[at]openlinksw[dot]com ) or skype me ( daniel.lewis ).

I quickly zipped up a poster for the “Bristol Knowledge Unconference“. It’s available as a PDF by clicking the following link:

In the past I’ve used the term “Universe of Discourse” in order to sum up the true meaning of Linked . Well, I’ve recently come across a great saying, which I believe is by the ’s which goes like this:

From you I receive, to you I give;
Together we share, and from this we live.

Which I think is a wonderful quote, and something to certainly think about in order to analyse exactly how you do live your life. As this has a direct impact on life, it is a real bonus if we can take this into computer science also… the first part (”From you I receive, to you I give”) we see in Initiatives, but in order to pick up on the second part (”Together we share, and from this we live”) we have to look towards (which together with the Open Data Initiative results in the Linking Open Data Project).

There is a lot of stuff in computer science which could take advantage of theories and practices within philosophy, psychology and even religion. The key is to be open minded!

Vincent Maher says in an online opinion article titled “Web 3.0 is only partly about semantics“:

There is nothing more frustrating than a gaggle of geeks sitting in your boardroom talking about simple concepts in an unnecessarily obfuscatory manner because their revenues are tied to your inability to understand what they’re saying or the bills you’re paying.

One of the prime targets for this confusion is the

Semantic Web. They will tell you it’s about artificial intelligence, acronyms such as RDF, object-oriented data structures and meta this and hypertext that. The bottom line is this: the Semantic Web is about bringing information to life.
I agree with Paul Miller in his comment when he says “Too right“… however! I’m also seeing it from another perspective (to slightly modify the quote above):

There is nothing more frustrating than a mob of managers sitting in the boardroom with you talking about simple concepts in a rather simple manner because their revenues are tied to your ability to understand what you’re saying. The top line is this “Linked Data is about bringing information to life”.

The Linked Data Web is an identical alternate universe, if you can perceive it in this universe then you can perceive it in the Linked Data universe. Imagine: art, science, society, business and academia are all linked to each other in this universe…. therefore we can have the same in that universe.

Kingsley Idehen has done a fantastic blog post highlighting the fact that we’ve already got a fantastic platform which encapsulates all of the necessary Linked Data, “Web 3.0“, Portable Data and WUPnP features (in addition to Relational Database and Application Hosting) in the form of Virtuoso Universal Server.

Go have a look now, the post is titled “Virtuoso’s Universal Server Architecture (Conceptual and Technical)“.
