The tempting rule to break

W3C has published new Semantic Web Logos (as blogged before) and with them, rules how to use them. One of the rules, which caused uproar in some blog posts and questions in mailinglists, was:

  • The logo may not be used to disparage W3C, its Member organizations, services, or products.

Also, the logo is not so distinctive as the triples.

The phrase alone triggers free minded web enthousiasts to do the right thing, namely, to question the other rules about photoshopping the logo 🙂

W3C published new Semantic Web logos

swhorzWe have a visual identity now! SWEO and the W3C communications team worked on different designs for a Semantic Web logo, to the right you see the nicely colored result.

They are available in different colors and tastes, like this:
owl in magenta

The three sides of the tri-color cube in these logos evoke the triplet of the RDF model. The peeled back lid invites you to Open Your Data to the Semantic Web!

W3C anticipates using the Semantic Web cube in conjunction with other imagery related to the Semantic Web. However, until the imagery is more widely recognized, it should not be used on its own. Please use the full logos above rather than the cube alone.

So, could someone please photoshop a picture of my head “opened up” instead of the triple on my forehead?

microsoft manager: “needed a robust and scalable RDF repository” –

In an easily overlooked Press release by Intellidimension, an interesting statement about RDF is done.

Read the interesting part first:
“We chose to integrate the Intellidimension solution based on the strength of its technology and the company’s semantic web expertise,” said John Deutscher, group program manager of Industry Solutions at Microsoft Corp. “We needed a robust and scalable RDF repository with tight integration into SQL Server 2005 to meet our goals for housing extensible metadata in Interactive Media Manager, and RDF Gateway addressed our requirements.”

intellidimension logoWell done! Managing media with this setup is probably very clever.
Intellidimension is the company that does RDFGateway, a compact, good-performaning RDF application building platform (store + gui).

The whole press release:
Brattleboro, VT, USA, May 21, 2007 – Intellidimension announces that Microsoft has integrated Intellidimension RDF Gateway in their new product, Microsoft Interactive Media Manager. Interactive Media Manager is a server-based solution which enables organizations to better manage the complexity inherent in the digital content lifecycle, from content creation to management to distribution. The solution, an extension of Microsoft Office SharePoint Server 2007, is specifically designed for organizations in the media and entertainment industry, including film, television & postproduction studios, broadcasters, game developers, publishers and advertising and marketing agencies.

We’re excited about our work with Microsoft, which combines Intellidimension technologies with their recently introduced Interactive Media Manager solution,” said co-founder and CEO of Intellidimension Geoff Chappell. “It’s inline with our business goals and is an important vote of confidence in our technology. It’s also a great sign for the semantic web in general that a technology leader such as Microsoft is embracing semantic technologies.”

As part of this integration, Intellidimension enhanced RDF Gateway to support Microsoft SQL Server 2005 as a storage engine for its RDF deductive database. This integration with SQL Server will be available widely with the next release of RDF Gateway, providing Intellidimension enterprise users all of the capabilities of RDF Gateway with the added reliability and manageability of SQL Server for their mission critical data.

“We chose to integrate the Intellidimension solution based on the strength of its technology and the company’s semantic web expertise,” said John Deutscher, group program manager of Industry Solutions at Microsoft Corp. “We needed a robust and scalable RDF repository with tight integration into SQL Server 2005 to meet our goals for housing extensible metadata in Interactive Media Manager, and RDF Gateway addressed our requirements.”

Sie haben gewonnen – superbonus49

Ich (L) war wieder mal der glĂĽckliche. Habe gerade einen Anruf einer netten Dame (D) von Superbonus49 bekommen, der etwa so ablief (genau weiĂź ich nimmer):

D: Hallo Herr Sauermann, sie haben gewonnen. Sie haben beim e-mail gewinnspiel mitgemacht und einen gutschein fĂĽr eine Kreuzfahrt gewonnen.

L: aha. interessant, e-mail?

D: Ja, wir machen das Gewinnspiel in Kooperation mit o2. Wir schicken ihnen den Gutschein zu. Ihre Adresse ist Pirmasenser Str 18?

L: ja.

D: Gut, Ihre postleitzahl ….?

L: Ja

D: dann bräuchte ich nur noch ihr Geburtsdatum, das wäre?

L: (naja, die säcke wissen eh alles, das ist auch schon egal, aber inzwischen würde ich es keinesfalls mehr sagen): DD.MM.YYYY

D: Gut. Zusätzlich zur Kreuzfahrt dürfen sie am Superbonus 49 Gewinnspiel Teilnehmen, und o2 zahlt 80% der Kosten, super was?

L: ja, toll

D: Das sind dann etwa 10€ im monat für drei monate.

L: Aha.

D: Ja und wollen sie das… das ist so toll … bla bla bla

L: Ich möchte mir das noch überlegen

D: kein Problem,….

L: Also das sind 10€ im Monat und ich bekomme per Post noch einen Gutschein für eine Kreuzfahrt?

D: Ja, den Gutschein haben sie auf jeden fall, und es sind 39€ im Monat.

L: aha.

…. es dämmmert…..

Ok, ein schneller internetcheck auf o2 und superbonus 49 ergibt heiĂźe 243 hits, also ist das alles defniniver Bullshit und gelogen was die Dame da verzapft hat, da diese Angaben nicht stimmen kann man wohl sehr gut auf die seriösität der Firma Superbonus 49 schlieĂźen. Betrug? Abzocke? Wohl nicht, Firmen wie Faber und Superbonus leben als “added value” zur Lotterie. Als gläubiger Christ bin ich zum GlĂĽck gegen jede Form von GlĂĽcksspiel allergisch, drum werde ich wohl nicht zusagen.

Andere haben es aber durchaus gemacht.

Nach deren Erfahrung kein Betrug, aber ein ernĂĽchterndes Erlebnis.

Bin jedenfalls gespannt, die Dame hat gemeint sie ruft morgen nochmal an, werde sie nach der Kontaktperson bei o2 fragen 🙂

warum ich das blogge? Falls der nächste danach sucht…

Now Queryable and open linked data: U.S. Census/Congress datasets: 1 billion triples

and its fast!

As you can’t blog enough about it, I am copying a story from this announcement email:
(following Text by Josh Tauberer)

Hi, everyone. (This is a revised/combined reannouncement for what was
originally posted on the Linking Open Data list.)

Last November, Chris Bizer wrote, “[T]he DBLP server increases the size
of the Semantic Web by around 10 percent ;-)” [1] Based on the same
logic, I have recently increased the size of the semantic web by 200%!
(in terms of the number of triples; and of course I’m also just joking
here w.r.t. size of the semantic web)

I’m announcing here a new U.S. 2000 Census dataset of 1 billion triples,
accessible over SPARQL and browsable by linked data [2] principles, and
re-announcing my U.S. Congress dataset which is newly browsable with
linked data principles. These two datasets are interconnected, and the
Census dataset is linked up via owl:sameAs to Geonames [3].

I like the Census data set a lot for three reasons— first, if you live
in the U.S. it has something for you, since it has detailed statistics
on geographic entities down to the level of small towns/villages, and
everyone lives somewhere; second, it meshes up with two other data sets;
and third, it’s rich enough on its own to support a wide array of
interesting and real-world useful queries (if, say, you were doing
research).

The OpenLink guys were kind enough to host the data set previously, but
I wanted to push the limits of my own semweb C# library [4] and I wanted
to be able to revise the data set as needed, so I’ve wanted to host it
myself, which only recently I was able to do (even though I’ve had the
triples laying around for nearly a year).

A complete description of the data set and how it was constructed and
exposed is here:

http://www.rdfabout.com/demo/census/

Some features of the data set:

Data on 3,200 U.S. counties, 36,000 “towns”, 16,000 “villages”, 33,000
ZCTAs (something like zip-codes), and 435 congressional districts.

Each of those locations contains around 10 thousand population
statistics, as well as a dc:title, a basic hierarchical structure
between regions, and latitude/longitude.

Very basic geographic/name/lat-lng data (1 million triples) can be
downloaded in N3.

All of the 1 billion triples are accessible via SPARQL. See:
http://www.rdfabout.com/demo/census/sparql.xpd which has a few sample
queries. An example query is “List the states in the United States that
have more students in dorms than prisoners.”

The URIs for the geographic regions are dereferencable http: URIs. (The
URIs for the predicates in the data set will be updated to be
dereferencable in the future.) For example, you can visit the URI for
New York State:

http://www.rdfabout.com/rdf/usgov/geo/us/ny

(Some URIs return very large pages that take Firefox quite a while to
render. That one’s OK.)

The dereferencable URIs return 303’s to SPARQL DESCRIBE pages describing
those URIs.

There is a sitemap.xml file based on the latest draft circulated [5],
referenced from robots.txt: http://rdfabout.com/robots.txt

And, source code to generate the triples from the Census download files
are posted. It’s too large for me to provide the whole RDF myself, for
now at least.

The U.S. Congress data set, which I originally made SPARQL-accessible in
December 2005 but is now revised to follow the new linked data
principles, has 12 million triples containing brief biographical data
for all members of Congress, and mainly data for federal legislation and
voting records going back a number of years. Here are two example
dereferencable URIs:

http://www.rdfabout.com/rdf/usgov/congress/people/M000303
(= Senator John McCain)

http://www.rdfabout.com/rdf/usgov/congress/109/bills/h867
(= a bill in Congress)

Some example Congress-related queries are posted here:
http://www.govtrack.us/sparql.xpd
And dump files are here:
http://www.govtrack.us/data/rdf/

An example I like to use is that one could fairly easily create a table
using SPARQL aligning votes on a particular bill by congressmen with,
for instance, the median commuting time to work of their constituents,
as reported by the Census.

Thanks to those who gave feedback on the LOD list — I haven’t been
able to address all of it yet (like how to deal with backlinks on the
dereferenced pages).

Foaf VS Walled Communities

The web 2.0 is getting richer based on the proprietary walls.
There is an often asked question: why is FOAF out there for years but nobody made a business model out of it? Easy: because when you open your service to be replaceable, you are replaceable. Imagine a world where you could switch your community website like you can already switch your newsreader today (thanks to OPML): Venture capitalists would sweat like a drunken grad student in final exam.

This post is partly inspired by this. There is a mix up of cause and effect: FOAF as a standard is making Web 2.0 services interoperable and standardized. Orkut, facebook, linkedin, studivz, (++) would all have the same API and an extensible data format if they used FOAF and RDF.

But wait – who is the venture capitalist behind these web 2.0 walls? Maybe you. So you suddenly realize that when your little nerds in the computer room switch the lever towards standards, your money may go down the well, because then your precious closed community of people, and that is what you sell and own: data about people, will be open for anyone else to copy. So you would do your best not going for standards but instead making the BEST social service EVER so that everyone DIGGS it and invites all HIS FRIENDS into closed walls. Capitalism is ok, but we have to name it what it is.

Like Dick Hardt from SXIP said in his well-known keynote: its your data, not theirs. FOAF and RDF is a way to get back your data from the web 2.0 companies that own you at the moment, make them give you back the data you have entered. Switching from Flickr to another photo community should be as easy as switching newsreader (thx to OPML) or Office Application (thx to OpenDocument).

Microsoft does not go crazy for a standardized OpenDocument format, which would help us get free from the monopoly that takes your money when buying a computer and invests it to sell XBoxes to your kid. Why should it be different with web 2.0? But thanks for pointing us to the VC view.

Doing Guest Research at L3S

Update from last post, I am in Hannover engaged in Research. Julien Gaugaz from L3S and I are working on the topic of Current work Context of a user for Nepomuk. This is tricky, as first of all, there are about 600 definitions of “context” (there is a paper about analyzing 66 of them using text analytics, context buzzword word that everyone uses with its own interpretation!) and second, we have multiple existing ontologies and implementations to integrate.

btw, this is the room for the Hiwis and guest researchers where I sit at the moment:
Here I sit
I will blog about our extensive literature research on context later this week.

In the meantime, Cedric Mesnage from Lugano interviewed all DFKI and L3S members about what they are working on in the project, to improve the architecture of Nepomuk and communicate it better, a good task.

We drank beer and looked at the rainy (no, its not raining, its only dripping, Hannoverians have 100 words for rain) city of Hannover.
To Heiko Haller I said in a chat, that we will probably end up in a Fiasko, but actually we started there:
Es fängt im Fiasko an

Besides, Cedric can not only do great art, he can also do photographs (bummer that the autofocus didn’t get this one perfect):
Leobard Light Angel

Research visit at L3S

I am currently guest researching at the L3S lab in Hannover. L3S does research on Semantic Web, e-learning, search. They are partner in the NEPOMUK project, and I will be working on the ideas of the context a user currently works in, to guess what somebody is doing based on observations done. This is important to give support to people, showing them information that is related to the task you are doing at the moment. (for example: you are reading this blog-post, and related information is l3s, dfki, nepomuk, leo sauermann, context).

I will be at L3S for three weeks, from 24.9.2007 to probably 14.10.2007.

Here is the building where I am sitting at the moment: KBS building with L3S people

Where I sitIts the L3S offices at KBS, AppelstraĂźe 4, 30167 Hannover. I am sitting in room 232. If you want to use this occassion to meet me, skype or jabber me first (check my foaf for how to).

Appartments from Gaststätte Kaiser I am living not far from that in an appartment room, where I have access to a kitchen and a bed, and free wifi for 90 minutes per day, great, what else do you need.

God and numbers blog

Mike Robb, my praying buddy in Kaiserslautern, and his lovely wife Katharina started a new blog to inform their friends about their trip and life in Aberdeen. They called the blog called “god and numbers” . Mike is a missionary, studying theology, Katharina is a mathematician, she worked for Fraunhofer before and is now searching for a Job in Aberdeen.

btw: Are you a company in Aberdeen, in need for a mathematician that can do stuff like this diploma thesis on “Spectral Analysis of Random Closed Sets. The Surface Measure Associated with a Random Closed Set”? Comment on their blog or write them.

The first blog post was about Mike moving his stuff. I showed up late for carrying, and then it became obvious that we had two problems. One was, that not everything will fit into the truck that Katharina’s dad has rented for the occasion. Using the great skills of re-structuring moving boxes I have learned with Ebo on my own move from Vienna to Kaiserslautern, we could solve that.

Here is the skills as used before:
Our stuff limited to a van
When we moved from vienna, in the van, the boxes reached up to the very ceiling and filled the whole thing. There was not place for one extra mouse in there. For Mike and Katharina, we produces a similar result, stuffing every item into the places of air that was left in the van (*proud of tetris skills*).

The second problem was, that we were not enough people. I came late, and besides me, the parents of Katharina were there. So, we were very lucky when two mormons biked by, saw the situation, looked, stopped, and asked if they could help. First we didn’t want to bother them, but looking at the situation, I asked them if they could help us carrying. They could, and then it was much easier. Love god, love your neighbour, love yourself, that is one of the many rules shared by our churches. Thanks god for giving these recommendations to make life better for this planet. At least for us, god works perfectly.
