Abstract: The year 2005 was a successful year for the MPEG
and Multimedia Metadata Community. The community was founded within a
first workshop in March 2005 in Klagenfurt, Austria, initiated and
organized by Harald Kosch. A second workshop, which took place at the
I-Know 05, the International Conference for Knowledge Management 2005
in Graz, Austria, was organized by Mathias Lux and Michael Granitzer
to enlarge the community and to plan future joint activities. With a
third workshop at the RWTH Aachen, Germany, organized by Marc Spaniol
and Ralf Klamma, the community grew further, aims of the community
were clarified and the schedule for 2006 was developed.
Within the three workshops a lot of topics and projects have been
discussed. The JUKM special issue on the MPEG and Multimedia
Metadata Community Workshop Results 2005 aims to distribute results
of community discussions and projects of the community members. The
contributions to this issue have been presented by at least one of
the authors at one of the above mentioned workshops. The discussion
of the community has been integrated and a scientific paper has
been generated. The publication has then been peer reviewed by
community members. Two different types of contributions have been
accepted. Technical notes are smaller in size, but present valuable
partial results of ongoing research. Full papers provide more in
depth discussion of applications and approaches as well as results
and conclusions. From the various presentations of the three
workshops in 2005 six topics have been selected for publication,
whereas only the last contribution is not a full paper but a
technical note.
The contribution "Analysis of the Data Quality
of Audio Descriptions of Environmental Sounds" by Dalibor
Mitrovic, Matthias Zeppelzauer and Horst Eidenberger from the
Vienna University of Technology in Austria presents an analysis of
a broad set of state of the art audio features and descriptors. The
information content as well as redundancy and dependency between
features is investigated. Furthermore a new measure for the
information content of descriptors based on variance is
introduced.
The article "MPEG-7 meets
Multimedia Database Systems" by Mario Döller from the
University Passau in Germany shows the impacts and requirements of
an integration of MPEG-7 as data model to multimedia database
systems. Topics like indexing and access structures as well as
query languages and query optimizations are addressed.
The paper "A Description
Infrastructure for Audiovisual Media Processing Systems Based on
MPEG-7" by Peter Schallauer, Werner Bailer and Georg
Thallinger from Joanneum Research in Graz, Austria, introduces a
metadata model for describing audiovisual content, which is
applicable to a broad range of applications. In addition access
tools for usage and manipulation of the model are introduced.
The contribution "Community Hosting
with MPEG-7 Compliant Multimedia Support" by Ralf Klamma,
Marc Spaniol and Yiwei Cao from the RWTH Aachen in Germany
introduces a novel information systems architecture for the
enhancement of community engines. Within their work they focus on
multimedia services and the MPEG-7 multimedia content description
interface.
The paper "Semantic
Applications on MPEG-7 Descriptions of
Multi-modal Meeting Corpora: First Results" by Victor
Manuel García-Barrios and Christian Gütl from the Graz
University of Technology, Austria, presents an architecture for
annotation and retrieval of multimodal data recorded on
meetings. Furthermore they describe the process of interchange of
low-level multimodal data between different heterogeneous
distributed services based on MPEG-7 descriptors.
The article "On the
Complexity of Annotation with the High Level Metadata" by
Mathias Lux from the Klagenfurt University in Austria and Michael
Granitzer and Werner Klieber from the Know-Center Graz, Austria,
summarizes the results of an user evaluation of the annotation of
digital photos with selected MPEG-7 description schemes, with focus
on the MPEG-7 Semantic Description Scheme in the only technical
note in this issue. The time taken for annotation by novice users
was compared for two independent tasks and compared to the medium
time used by a professional user for annotation.
