Following Cow Paths

I’m here at the 2nd Symposium on Media Informatics in Bonn “Cow Paths: Agency in Social Software”. The main thing it is about is social software, but well … it has something to do with multimedia and metadata: According to Marc Smith, a sociologist from Microsoft Research, people leave traces (in bits and bytes) -> people start recording their lives in different aspects: sounds, images, videos, text, etc. Furthermore they generate a lot of patterns and metadata from their behavior. In a sense this allows more and more social studies … and it allows to infere semantics from different dimensions of user generated metadata. (see also their project netscan)
This process is discussed in length within the workshop on the symposium, which we (Armin Ulbrich and myself) are giving tomorrow … so stay tuned (we will post the slides on the portal associated to the event and give the link here to).

CfP Workshop Multimedia Semantics – The Role of Metadata

6th Workshop of the Multimedia Metadata Community (see also here).

The web 2.0 will be a multimedia web. In order to make multimedia services ubiquitous, accessible and interoperable we need new mechanisms to describe and process the semantics of multimedia artefacts on the web. Metadata, mostly linguistic data about multimedia artefacts, will play an important role in these mechanisms.

The overall objective of the workshop is to investigate the current practice of multimedia metadata for contextualized ubiquitous, accessible and interoperable services on a higher semantic level, e.g. in collaborative working environments. We concentrate on the development of services and test beds for MPEG-7 and MPEG-21 based services, but also contributions related to other multimedia metadata description standards are welcome. The majority of multimedia metadata description standards in use is based on XML. This has important consequences on the development of services and test beds on the database, the infrastructure and the interface level. We are encouraging especially contributions from interested research groups from the database, the web service and the web 2.0 area.

This is the 6th Workshop of the Multimedia Metadata Community ( We want to extend this very active and successful community with new members.
