Year: 2008

Happy Birthday, Free Web. On April 30 1993 (well, I am a week late to gratulate, but anyway) CERN published the software and standards of the web as free software.

“CERN’s decision to make the Web foundations and protocols available on a royalty free basis, and without additional impediments, was crucial to the Web’s existence. Without this commitment, the enormous individual and corporate investment in Web technology simply would never have happened, and we wouldn’t have the Web today.”

Tim Berners-Lee, Director, WWW Consortium

(10 years of web)

The original announcement says “CERN relinquishes all intellectual property rights to this code, both source and binary form and permission is granted for anyone to use, duplicate, modify and redestribute it.”

Through my HTTP and HTML based weblog, I can only say: thanks Mr W.H. and H.W. !

Jean-Jacques Solari provided a French translation and Yakura Masataka a Japanese translation of the Cool URIs for the Semantic Web note.

Excellent!

do you miss the document in your language? Create a translation (and get in touch with W3C, I am not responsible for putting the translations on the site)

We need some facts about what the Semantic Web can be used for. The SWEO case studies provide a great start, listing deployed corporate Semantic Web applications. I added them up, identifying some key benefits: profit, data integration, querying, and taxonomies.

Read my notes.

At ISWC2005, one talk presented a slide about “what are the key reasons to use Semantic Web”. Sadly, I lost the reference and the paper did not list them (do you know which paper this was? It was presented in the industry track).
Interestingly, there is not much data available about the actual benefits of deploying Semantic Web technology. To create such overviews, we can either do interviews and questionnaires or look at documented case studies.

The Semantic Web Education and Outreach SWEO Interest Group of the W3C did collect and publish 27 case studies and 10 use cases (numbers as of 22.4.2008). The case studies report of deployed systems, therefore I concentrate of them. As methodology, I copy/pasted all key benefits into a spreadsheet and mapped them to classifications I made up on the run. I added explanatory text about the categories by copy/pasting statements by the authors. Then I sorted the results, showing the top-named benefits first. One argument from a use case could map to multiple of my categories (i.e. when a benefit touches both a business profit and is about data integration, it will be added to both categories).

Read the whole report with the data.

The correct scientific method to do such study would be to use questionnaires and to check if the statements given by the authors are true, so the scientific value of this note is questionable, but I love controversy.

I am currently attending the Semantic Days 2008 in Stavanger. From the speakers, you recognize it’s a melting pot of Defence (Rear Admiral Morten Jacobsen and Major General Arnvid Løvbukten), Oil&Gas (StatoilHydro, DNV, NOV, Epsis) and Semantic Web. For the last subject, amongst others, Ora Lassila and Ian Horrocks presented. I also fall in the last subject.

The conference is located at Clarion Hotel Stavanger, in the city center. From my room I have a great view of the sourrounding sea and town, but there is not much time to go there.

My presentation contains some new data about the use of semantic web technologies, but I will blog that extra, as it deserves some more space.

I visited CHI2008 last week, and finally found time to upload the pictures and videos.

The Semantic Days 2008 Conference will be next week, Stavanger, 21-23 April 2008. From Monday 21 to Wednesday 23 April 2008 at the Clarion Hotel, Stavanger.

In the words of the organizers:

Semantic Days is an annual conference that has become a meeting place for industrial use of Semantic Web technologies with significant contribution also from research institutions and universities.

My talk will be on Semantic Web in use on the first day.

For the interested social researcher:
I let xing.com check if people from my desktop address book are on xing, and if I am connected with them (a feature that linkedin had before them, I think).

• 623 contacts in my address book have email addresses and can be compared
• 105 (17%) of them are Xing members
• I am already connected with 52 (8%) of them

Does this say anything scientifically? Hm….

and, you 53 people, expect to get mass-mailed soon…

For the german readers….

Springer hat Kapitel aus einem Buch bei dem ich beigetragen habe online, aber nur für Springer Abonnementen (und eigentlich ein alter Hut, aber vielleicht doch für jemanden interessant)

” Semantic Web – Wege zur vernetzten Wissensgesellschaft”

Why should you provide the data of your website in RDF? To let the users use it! If you got news on your page, you may already have an RSS feed, but if you got calendar items, people, friend networks, tags – triplify them! Then the users can mashup the data they created.

And you can win a MacBook Air 🙂

http://triplify.org/Challenge

The
I-Semantics Conference
includes a Linking Open Data Triplification Challenge which will award three prizes to the most promising triplifications of existing Web applications, Websites and data sets. The prizes are:

• MacBook Air or Euro 1.000 (1st prize)
• Asus EeePC or Euro 300 (2nd prize)
• iPod Touch or Euro 200 (3rd prize)

For the success of the Semantic Web it is from our point of view crucial to overcome the chicken-and-egg problem of missing semantic representations on the Web and the lack of their evaluation by standard search engines. One way to tackle this problem (some might say the only one) is to reveal and expose existing structured (relational) representations, which are already backing most of the existing Web sites. The Triplification challenge aims to expedite this process by raising awareness and showcasing best practices.
