A problem of semantic web: not providing XML value

Today in the morning, I had a sudden “insight” about one of the problems of RDF and Semantic Web: it misses some of the value that XML offers. This is what my daily commuting bike ride is for, thinking…

The adoption of Semantic Web rises and falls with the adoption of it in standardization bodies. For example the Oil&Gas industry of Norway is thinking about Semantic Web, and I have recently been talking with people from the automotive supplier industry about Semantic Web. To interchange data in a business-to-business environment you would expect that RDF has more features than XML, but in fact, it doesnt.

  • RDF is less expressive than XML. One example: you can’t define pattern in RDF. Look in the XML spec, there is much more of it missing in RDF.
  • RDF is not validated. Although in theory, it is possible to validate a file for semantic correctness, nobody does that because of the open world assumption. Hence, there is no validation of the XML in mainstream applications.

So, if you are an industry, you already havean XML based standard, moving to RDF without the expressiveness of XML and without the notion of validation is tricky. RDF should have more features, not less.

Also the stack of XML technologies must be embraced better, for example a XSLT-friendly RDF/XML serialization. Please, dear reader, solve these problems and make a company around it.

Springer’s “Social Semantic Web” is out – kauf mich.

On Friday we received our author copies of Springers new masterpiece of Semantic Web books. Springer’s “Social Semantic Web” – Web 2.0 – was nun”

Social Semantic Web Happy Authors

From left to right: M, Kinga Schumacher, Ansgar Bernardi, Leo Sauermann. We all were authors on the chapter on “Semantic Desktop”, Malte additionally contributed to the chapter on Semantic Wikis. As you see we are very happy about our complimentary author’s copy. Besides that – das buch ist gut.

Read it – in deutsch 🙂 . The authors (besides our small contribution) are the who-is-who of the German-speaking Semantic Web. Chris Bizer, Sören Auer, Sebastian Schaffert, Krötsch&Vrandecic, etc …

edited by Andreas Blumauer and Tassilo Pellegrini, it brings together many authors from the practical side.

Welcome the Bush Depression

As said on reddit, the other was coined “The Great Depression.” We start referring to the coming one as “The Bush Depression.” It’ll be one for the history books.

Listening to the radio news this morning, I heard that the US gov did not find 700billion in their piggybank to give away to scrupulous banks who screwed up their economy. Uhoh. Well, we are all in one boat, and if the US goes down, it will affect global economy. In the radio they mentioned the national banks of Belgium and Germany having to react (something like “have to print more money” but I didn’t get it…)

If the bank bubble affects the web2.0 bubble, I may lose my flickr pics and del.icio.us bookmarks, but Knallgrau, the european company hosting this blog is living on company contracts and will probably survice (I hope). Looking forward to the economy next year with mixed feelings – it will probably sort out itself.

If not, look for health packs and ammo on elevated places within the mayhem on the streets.

ESTC2008 wrapup

I attended the ESTC2008 conference.

One day to ESTC2008, one day into KI2008

I am still at KI2008 conference (which is located on the ground floor of the building where I work, so not attending the conference is hard 🙂 and will go to ESTC2008 tonight.

As blogged before, I will be speaking at ESTC2008, on 25th September 2008 around 16:45 in the Rittersaal room.

The topics of my talk will be circling around Semantic Desktop, personalized Semantic Web, and how this is used or can be used in company settings

  • Why is Semantic Web needed on the desktop?
  • How does data fusion work on the desktop?
  • What is a personal information model?
  • How do existing user interfaces and user experience change?
  • Which projects are active and what are their results?

Digitaldruck und Persönliches Wissensmanagement

Wo finden sich Benutzer die mit viel Information zu tun haben, Kunden, Projekten, Themen? In den Printmedien.

In meiner Umgebung ist der Digitaldruck der Wahl bei www.direktprint.de. Die Frage ist, wie in so einem Unternehmen mit Information umgegangen wird. Nun, ich habe den Geschäftsführer kennen gelernt und kann mal in seine Prozesse gucken.

Der Prozess an sich ist faszinierend, Digitaldruck, Großformatdruck, Dissertationen (ah!), Masterarbeiten (oh, meine Studenten), und alles Online. Das interessante ist der sweet spot wo man ein Produkt anbieten kann, also von der Massenware abgehoben. Direktprint sieht zwar im Büro sehr “überlagert” aus (well, es geht um Papier und das stapelt sich hier meterhoch), die Qualität der Ergebnisse sieht aber nett aus.

Gut, nun will ich in den nächsten wochen mal rausfinden, wie hier so die emails und dateien durch die gegend fließen, und ob die Leute hier den Semantic Desktop brauchen.

Clay Shirky on Cognitive Surplus

A truly impressive and visionary speech, summing up why we do web 2.0. Must see Clay Shirky explaining what TV has grabbed for the last 50 years: our cognitive surplus. (of course, you all have already seen it, its from April 2008)

watch:

Excellent quotes (some literally, some only overlap in meaning, wasn’t quick enough to type everything)
(telling a story he experienced)…
TV Reporter: Where do people find all the time to do wikipedia?
Clay Shirky: No one who works in TV gets to ask that question.
You know where the times comes from. It comes from the cognitive surplus you have been masking for the last 50 years.


Warcraft: grown men sitting in their basement pretending to be elves.
At least they are doing something.

… the amount spent watching TV worldwide equals to creating 10.000 wikipedia projects each year…

She looks behind the TV fumbling through the cables, and we wondered… she said she is “looking for the mouse”
