Daniel’s Blog

I’m quite tired as it’s quite late and I’ve been working on the new site all evening. But, I have just released it! It’s called lc8n.eu

The site is a web application which acts a bit like a URL Shortener, but for locations instead. It forwards you to a map of a particular location.

Heres an example of where I am:
* https://lc8n.eu/a

It’s at the very beginnings of it’s life, and I’m planning to do a lot with it. I hope you enjoy using it! You can use it like this (via twitter):
“Hi everyone. I’m currently located here: https://lc8n.eu/a , quite tired because I’ve been working on the new site all evening.” - https://twitter.com/danieljohnlewis/status/5993518753

As I say. It is quite early on in its life, so if you have any thoughts, comments or bugs that you’ve spotted then please do get in touch. I’ll be more than happy to answer.

Well I’ve released details of the Bristol Knowledge Unconference 2009.

Our main website is: Bristol Knowledge Unconference 2009 : https://www.craftivism.net/wiki/UnCraftivism/Bristol_Knowledge_Unconference_2009

It will take place in the Arnolfini Arts Centre in Bristol on the 12th and 13th December 2009 as part of the “unCraftivism” satellite event which is part of the Craftivism exhibition. unCraftivism is about merging technology and art, and Bristol Knowledge Unconference will be one stream of working during that weekend, other events during the weekend will be done in collaboration with Dorkbot Bristol and the Bristol Robotics Lab.

The Knowledge Unconference will be similar to what it was last year, it’ll be all about Knowledge - although we’re slightly more focused this time and have a subtitle: “The Art of Knowledge”, and will experiment with the mixture of art and science that is knowledge. Last year we were lucky to have over 50 people turn up from diverse areas of expertise such as: Knowledge Management, New Media, Semantic Web, Business, Chemistry and Psychology… and we hope to continue to have a diverse mixture of people to take on the subject of knowledge, with a twist of art.

I hope that you will be able to join us, as this will be a really exciting event.

I was wondering about the Presidents in the United States of America, and wondered what their religions were. So I zipped up some SPARQL queries to run against DBpedia, they aren’t perfect (i.e. they don’t capture all of the presidents due to mislabeling and me not being too bothered about the answers), but it provides some answers.

The Democrats:

SELECT ?PresidentName ?ReligionName
WHERE
{
?president
dbpprop:party <https://dbpedia.org/resource/Democratic_Party_%28United_States%29>;
dbpprop:order dbpedia:President_of_the_United_States;
<https://dbpedia.org/ontology/religion> ?Religion;
rdfs:label ?PresidentName.
FILTER (lang(?PresidentName) = "" || langMatches(lang(?PresidentName), "en")).
?Religion rdfs:label ?ReligionName.
FILTER (lang(?ReligionName) = "" || langMatches(lang(?ReligionName), "en"))
} ORDER BY ?ReligionName

Which the answer is viewable “Democratic Presidents Religions”

The Republicans

SELECT ?PresidentName ?ReligionName
WHERE
{
?president
dbpprop:party <https://dbpedia.org/resource/Republican_Party_%28United_States%29>;
dbpprop:order dbpedia:President_of_the_United_States;
<https://dbpedia.org/ontology/religion> ?Religion;
rdfs:label ?PresidentName.
FILTER (lang(?PresidentName) = "" || langMatches(lang(?PresidentName), "en")).
?Religion rdfs:label ?ReligionName.
FILTER (lang(?ReligionName) = "" || langMatches(lang(?ReligionName), "en"))
} ORDER BY ?Religion

Which the answer is available directly here: “Republican Presidents religions”

Please note

• It doesn’t return all presidents of the parties
• It does use the DBPedia SPARQL engine (powered by OpenLink Virtuoso)
• It does use some shortcuts (i.e. not defining PREFIXs and the FROM clause), as the DBPedia SPARQL engine provides these nice shortcuts.

It’s absolutely fantastic that more and more people are taking up Semantic Web solutions and providing RDF.

Guys and Girls it’s time for the next step!

This is something that I’ve been thinking about for a while. People, although they are taking up the SemWeb, they don’t seem to understand the full power of it’s expressiveness. This isn’t a providing problem, this is a usage problem…. Yes it’s fantastic that we can interlink objects now, but what does it mean to be an object? What can we learn implicitly and explicitly from this highly-structured and highly-distributed web of data objects? and finally, what can we do with what we learn?

These questions are the real heart and real soul of the Semantic Web, and an area in which us Semantic Web advocates have really mentioned much before.

And please note, this shouldn’t *just* be an academic thing. Systems which embrace this, and which are in the wild, would greatly benefit. It’s breaking down the walled-garden and combining the intelligent systems which have previously been in websites like amazon.co.uk and google, and exposing those methods to the real semantic data.

The key to all of this is improvement of society. If your project improves society (or helps the environment in some way), then your project should be excellent. Whether or not it makes money!

Hope this all makes sense…. feel free to ask questions, or give your opinion.

Here are some predictions for Computing & IT in 2009:

• Hardware
  • More and more Cloud Computing services (and improvements)
  • Personal Supercomputer Hardware (such as NVidia Tesla)
• Software
  • Advancement of ease-of-use in Operating Systems, particularly Linux… which will see more of a take up this year than ever before.
  • Browsers (particularly Mozilla-based and Opera) will start to contain more and more Semantic Web based features.
• Web
  • More people and organisations providing Semantic Web services. Leaders in this field will help greatly, such as the BBC, BT and the UK Government.
  • The original developers and advocates of the Semantic Web, will start to move away from it a little in an attempt to improve the semantics of the Semantic Web. Areas such as Fuzzy Logic, Bayesian Probability, Advanced Description Logic, Intelligent Agents and Artificial Neural Networks will be bridged with the Semantic Web by researchers.
  • Web development will become more and more like desktop application development.
  • Web design will become more focused on providing the data rather than providing pictures, fusing with Information Architecture.

BUT! More importantly, things may seem to slow down in terms of development within the computing field. This won’t be entirely the case, we’ll see more efficiency improvements than feature additions… and these developments will probably help the efficiency of those companies using that software/hardware.

Although I’ve mentioned all of this. Please note that I truly feel that we should move away from a materialistic view to a more societal and/or spiritual point of view. This means that although new things may be released in the future, we should recognise them, but not be tempted by them if they are not necessary updates.

Good News!

My second article through IBM developerWorks has been published! (there are one or two things wrong with this article, I won’t say anything about it for now and will try to rectify it asap!)

It’s titled “Building Semantic Web CRUD operations using PHP” (<- click the title to go read it). It’s essentially about showing:

• The similarities and differences between the Relational Database Model and the Resource Description Framework model.
• The similarities and differences between SQL and SPARQL.
• How to implement SPARQL calls for Creation, Reading, Updation and Deletion (CRUD) operations using PHP.

After a bit of toying with it (keep at it, because it will be challenging but worth it!), you should be able to build your Web Application with RDF and SPARQL manipualtion.

If anyone has any questions about it (or about my previous developerWorks article which was titled “Intelligent Agents and the Semantic Web“) then please do let me know.

Oh yeah, by the way… both of my articles so far have been “featured” articles on the IBM developerWorks front page

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 machine learning techniques. I’m also interested in their automatic ontology 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.

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.

What happens when you combine:

• BBC Radio Data
• BBC Radio Online Listening
• Attention Profiling
• OpenID
• OAuth
• Ruby on Rails

Something called Radio Pop!

Radio Pop is a prototype system by the BBC Radio Labs, it has the eye candy and a good concept… let’s hope that it goes further! They’re certainly heading in the DataPortability, Linked Data and WUPnP direction, which is fantastic and will help with the future evolutions of the Web.

I’m hoping that they’ll release an RDF and SPARQL API in the near future (at the moment they have a plain XML based API).
