Abstract: The motivation for emerging the concept semantic web is due
to the fact that search engines and text-based exploring are no longer
adequate as these approaches involve an extensive information retrieval
process. The deployed searching and retrieving descriptors are naturally
subjective and their deployment is often restricted to the specific
application domain for which the descriptors were configured. The new era of
information technology imposes different kinds of requirements and challenges.
Automatic extracted audiovisual features, as these features are more
objective, domain-independent and more native to the audiovisual content are
required. Therefore, this presentation is a detailed trail to introduce to the
researchers, experts, students and practitioners very valuable references and
guides to lead them through their exploration and researching the multimedia
content and semantic web. The results of leading researchers from around the
world are successfully collected in one concise presentation in very semantic
manner.
This highly informative presentation includes three parts to construct a
valuable reference resource for researchers, student and experts dealing with
the emergence of integrated semantic multimedia field.
The presentation introduces the concept of semantic web and multimedia content
analysis to the readers through a logical sequence from standards and
hypothesis through system examples, presenting relevant tools and methods. In
addition, this presentation addresses approaches applied to specific problem
domains such as content search, indexing and retrieval.
The attendees may attain sufficient knowledge to start projects or researches
related to the presentation theme from finding recent results and articles
related to the active research area of integrating multimedia with semantic
web technologies.
The semantic web technologies are elaborated and ontology representation has
been emphasized. The presentation provides an excellent summary of the
fundamental theory behind applying a knowledge engineering approach to vision
problems. This summery iconize the concept of semantic web and multimedia
content analysis. A definition of the fuzzy knowledge representation that can
be used for realizing on multimedia content applications has been provided
with comprehensive analysis.
The second part of presentation introduces the multimedia content analysis
approaches and applications. In addition, some examples of methods applicable
to multimedia content analysis are presented.
Multimedia content analysis is very diverse and concerns many other research
fields at the same time. Multimedia content analysis has strong diversity
issues, as it starts from low level features such as (colors, DCT
coefficients, motion vectors, etc.) up to the very high and semantic level
(Object, Events, Tracks, etc.). The second part includes topics on structure
identification (e.g. shot detection for video sequences), and object-based
video indexing. These conventional analysis methods are supplemented by
results on semantic multimedia analysis, including development and use of
knowledge models for automatic multimedia analysis.
The final part of the presentation discusses and describes example systems
which current projects have been implemented, and include extensive results
and real demonstrations. For example, real case scenarios like ECommerce
medical applications and web services have been introduced. Natural language,
speech and Image processing techniques and its application for multimedia
indexing and contentbased retrieval have been elaborated with extensive
examples and deployment methods.
