This is just an entry I made to take a picture for
navigation on the frontpage. Nothing special to tell
you today, just for reasons of creativity ... or at
least what I consider to be creative ...

After about one year of intense work, Florian has now
finished his diploma thesis, where he developed a
framework for abstracting sensor technology from
application logic in the area of tangible user
interfaces.
As he's the first, who has finished a thesis I supervised, I'd like to thank him for his patience and the fruitful discussions we had during the last year. Maybe we're going to present his work in a paper on this year's WETICE - Paris can be really nice in autumn ...

Semantic Networks and Topic Maps
13.02.07 17:23 published under Research
What I also have dealt with in the last weeks, was
representation and semantic augmentation of
structured data in semantic networks. I mainly
thought about this in the context of organizational
learning, where we consider it necessary (as an
enabler) to provide users access to information in
their current work context. To lay the foundations, I
have developed a concept for unified representation
of work process models, learning content and
communication tools.
For technical realization I have used ISO Topic Maps, which proved to provide the flexibility I needed for these purposes and at the same time are a well-defined, standardized means for representation of whatever content ... or to cite the standard: [...] anything whatsoever, regardless of whether it exists or has any other specific characteristics, about which anything whatsoever may be asserted by any means whatsoever.
As the Topic Map standard has been recently updated to version 2.0 (with major changes in both data model and serialization format), I have implemented a topic map engine (in Java) to cope with these new elements. Together with some of my students, I currently working on a persistency layer, which will provide storage of Topic Maps in XTM-format as well as in relational databased (via Hibernate). When the implementation has reached a mature state, we will probably think of making the engine publicly available.
