Description
In recent years significant advances have been made in the area of automatic extraction of low-level features from audiovisual content. However, little progress has been achieved in the identification of high-level semantic features or the effective combination of semantic features derived from different modalities. Knowledge acquisition is becoming a key-enabling factor of the above tasks towards more scalable and reliable solutions, and thus its automation is becoming critical.

As the deployment of knowledge enhances the robustness of extraction while on the other hand the continuous extraction of semantic information can enrich this knowledge, synergistic approaches that combine multimedia extraction and knowledge evolution in a bootstrapping common framework to introduce new opportunities in semantic multimedia applications. Integration with additional sources of information, e.g. by using human annotation tools or real-time event services, may further simplify and disambiguate semantic multimedia information systems. Moreover, adaptation to a particular domain, for example to sports events, such as the Olympic games, is essential in order to reduce the complexity of multimedia analysis. In this context, unified modeling and representation of multimedia and domain-specific knowledge, ontology evolution, and standard and non-standard inference services for multimodal semantic knowledge fusion, form cutting edge technologies.

Key note speakers at the workshop:
Fabio Ciravegna, University of Sheffield
Alan Smeaton, Dublin City University

Topics of Interest
This workshop invites contributions on all topics related to semantic multimedia information systems. Special emphasis is given in challenging applications, such as the analysis of sports broadcasts. We anticipate some significant discussion owing to differences in opinions about approaches to take in solving the relevant joint problems, and we invite you to join the workshop to give your views on the following, as well as related topics

* Knowledge-driven multimedia analysis
o Video, image, audio and text semantics extraction
* Knowledge representation and reasoning for multimedia understanding
o Multimedia ontologies
o Deductive, abductive, rule-based reasoning
* Knowledge-based production support systems
* Knowledge-based systems in real-time environments
* Ontology evolution
o Ontology enrichment, learning, population and coordination
* Fusion of knowledge extracted from multiple data sources (channels, modalities, streams)
* Real-time algorithms with or without hardware accelerations
* Semi-automatic offline or online human annotation
* Personalised content broadcasting
* Recommendation systems and collaborative filtering


Aims of the Workshop
This workshop aims to bring together researchers and members from the industry interested in semantic multimedia information systems. In particular, it targets researchers dealing with multimedia analysis, annotation, evolution, reasoning, real time analysis of audiovisual data and multi stream analysis. It also targets professionals working with semantic multimedia information systems in image and video databases, audiovisual archives, sport industry, media production and broadcast industry, etc.

Workshop Structure
The workshop will be divided into two sessions, each of which started with a keynote speech. Confirmed speakers are Alan Smeaton (Dublin City University) and Fabio Ciravegna (University of Sheffield). Each session will include presentations of accepted scientific and technical papers from the community. Accepted posters will be presented during the session breaks. The workshop will be concluded with a panel discussion involving the invited speakers, representatives of the projects LIVE and BOEMIE and the audience.
