the first screenshot of gnowsis in combination with the semantic wiki.

This screenshot shows how kaukoluwiki and the gnowsis-beta work together.

A wiki-page just created using the JSP-wiki clone kaukoluwiki shows up in the gnowsis swing gui and vice versa.

The trick behind: both graphical user interfaces access the same data, stored using the PIMO-ontology and available in a sesame2 store.

semantic web rocks, semantic desktop rolls!

Just started sesame1 inside our gnowsis beta 0.9 which runs under sesame 2.0 alpha 3.

So this weird picture puzzles me: It says we have a web-interface for sesame 2.0 alpha 3. Note, that no one ever programmed this web-interface. It was just there. yeah!

re-launched my website using rdfhomepage

I re-launched my website using rdf-homepage, our cuper-cool rdf hack of DFKI to generate homepages using RDF and php.

See yourself the beauty of my new website, that is generated from about 10 different rdf files, including:

  • my foaf file
  • our organisational rdf model (DFKI organisational structure as rdf)
  • an rdfhomepage config file
  • my bibtex file
  • my bibtex file as RDF/bibtex

to make this magic work yourself, checkout our big-hack at

Mandriva joins the Nepomuk Semantic Desktop!

So here it is official . Mandrive Linux, with Cognium System as Partner has joined the Nepomuk Social Semantic Desktop project.
This project will rock the world, changing the way people interact with computers and socialise.

Basically, this is the thing we have been working on for years and I am happy to also be part of this project.

Read the webpages at and checkout the people involved with it.

emotional computerspeak: the perfect coutput

The landscape of open source speech synthesizers is growing richer. The
German Research Centre for Artificial Intelligence (DFKI), partner in
the Network of Excellence HUMAINE on emotion-oriented computing, has
decided to release its emotional text-to-speech synthesis system MARY as
open source.

The system can be downloaded from

MARY is a multi-lingual (German, English, Tibetan) and multi-platform
(Windows, Linux, MacOs X and Solaris) speech synthesis system. It comes
with an easy-to-use installer — no technical expertise should be
required for installation.

What i liked best is the emotional speaking plugin to play around. Brings up a feeling of c64 speech synthesis but with emotional blendings, great thing to automatically generate the swearword of the day or to motivate yourself by letting mary say how wonderful your work is, repeating for hours.

semantic desktop bits and pieces: leaftag

Just forwarded to my by Frank Osterfeld:

Announcing Leaftag, our desktop tagging framework. This is an evolution of the original prototype we created, originally named fstaglib (isn’t leaftag just so much better?).

The main part of Leaftag is a library called (oddly enough) libleaftag, which interfaces with the tag database. It’s GObject-based, and the API is quite small. It can tag anything with a URI.

There’s tagutils, a small app used for working with tags and files. It is able to tag and untag files, list all known tags, list all files with a specified tag, and manipulate tag properties (such as icons and descriptions). It also includes some symlinks that provide shortcuts to common tagutils functions (tag, untag, tagls, tags, and tagprop).

leaftag-python contains Python bindings for libleaftag. It simplifies the already simple libleaftag library.

software design

There are two ways of constructing a software design: one way is to make it so simple that there are obviously no deficiencies; the other way is to make it so complicated that there are no obvious deficiencies.”

why “secondlife” is not cyberspace

One of my scientific goals is to be part of cyberspace, to make this possible. Cyberspace means for me, that the world as we know it extends seamlessly into the information world, and things I do here and there are mixed. I go order a pizza by walking (in cyberspace) to the pizza people and doing it, the pizza itself comes here real life.

So let us look at products like Second Life.
Second Life is a 3-D virtual world entirely built and owned by its residents. Since opening to the public in 2003, it has grown explosively and today is inhabited by nearly 100,000 people from around the globe.

  • From the moment you enter the World you’ll discover a vast digital continent, teeming with people, entertainment, experiences and opportunity. Once you’ve explored a bit, perhaps you’ll find a perfect parcel of land to build your house or business.
  • You’ll also be surrounded by the Creations of your fellow residents. Because residents retain the rights to their digital creations, they can buy, sell and trade with other residents.
  • The Marketplace currently supports millions of US dollars in monthly transactions. This commerce is handled with the in-world currency, the Linden dollar, which can be converted to US dollars at several thriving online currency exchanges.

I see that the technics are nice, but its not immersive. At the end, Ultima Online may be more immersive than Second Life (compared to interaction possibilities).

Key here is the business department: What kind of business we see in Second Life. There is no real life business there – Where is the sneakers shop in second life that has real life sneakers on the store window? You have this kind of shop in the cyberspace described in the book Otherland, and thats useful.

So – we learn that the 3d technologies are here and the community and customers do exist, but the cyberspace product misses.

the game I always wanted

And now passively play!


go here:

The idea of Idle-RPG is to idle. Idle means, doing nothing. Winner is, who can do nothing longer than the others. In between, while you idle, the game itself plays for you. Every few minutes, you may stumble into an opponent, fight, steal something, find items, etc. But you cannot control this, the game does it for you. So, the perfect use of waste of time. Horray for computers, finally a game I want to play for years.

Shunn those fancy 3d games, come to the chat room and idle. Lets do nothing for years, see how our characters evolve and the world spinning around us. My char-name: Bush And His Pony, evil Alignment.

the great escape 5

am 6.2.2005, also gestern im Glockencafe. Diesmal warens zwei Worte die uns inspiriert hatten: Powerpoint Karaoke. Das hat als Inspiration völlig ausgereicht, zwei Worte. Also, frisch und fröhlich an die suchmaschine der Wahl und Anfragen dieser Art gestellt, und nach ein paar Stunden arbeit, redaktioneller Kürzung der Folien wars getan.

mehr blogging hier

Der Abend – ein großer, ein herzlicher, ein Cultural Hack. Nach unserer üblichen TheGreatEscape Einführung über Kaiserslautern im Netz gabs Karaoke. Die Themen der Folien waren in etwa:

  • Das Tourismuskonzept Bad Hindelang
  • Die Schweizer Sozialistische Partei
  • Sexual Mechanics and Glass Dildos

Nach insgesamt neun Vorträgen war der Abend perfekt. Die etwa 30-40 Gäste haben einstimmig das ganze als sehr gut befunden.
