CfP 2nd Workshop on Data Semantics for Multimedia Systems and Applications (DSMSA2009)

In the last decades, substantial progress has been made in content analysis, multimedia streaming, and human-centered computing to facilitate the development of large-scale multimedia systems. Together with the recent progress on semantic web, scalable machine learning, and multi-modal interaction, it is now possible to build a new generation multimedia applications that enable large-scale semantic representation, analysis, and delivery of multimedia data from heterogeneous data sources. However, there is still a long way to go for mature solutions of multimedia database systems that are capable of processing semantics-rich, large-volume multimedia data. It could be even more challenging if such systems are under stringent functional and non-functional (e.g., QoS) requirements.

The goal of this workshop is to bring together researchers in multimedia semantic computing and provide a forum for multidisciplinary research opportunities, with a focus on how to apply the semantic technologies to the acquisition, generation, transmission, storage, processing, and retrieval of large-scale multimedia information. Discussions on future challenges in multimedia information manipulation, as well as practical solutions for the design and implementation of multimedia database software systems are also encouraged.

Topics of interest include but are not limited to practical areas that span a variety of aspects of multimedia semantic computing including

  • Automatic generation of multimedia presentations
  • Semantic multimedia metadata extraction
  • Annotation tools and methods for multimedia semantics
  • Media ontology generation/learning/reasoning
  • Content-based multimedia analysis
  • Social media computing
  • Web-scale multimedia mining and retrieval
  • Multimedia indexing, searching, and retrieving
  • Multimedia streaming
  • Multimedia data visualization
  • Semantic-based QoS control and scheduling
  • Semantic-based Internet data streaming and delivery
  • Multimedia standards (e.g., MPEG-7 and XMP) and Semantic Web
  • Semantics enabled multimedia applications (including annotation, browsing, storage, retrieval, and visualization)
  • Semantics enabled networking and middleware for multimedia applications
  • Service Infrastructure, technology, and tools for Multimedia software systems

Music portal reduced to max: Grooveshark

Lately it was getting more and more challenging to hear a song you want online. YouTube sorts out based on Geo-IP, samples in online stores get shorter if even there. But I was pointed to a straightforward portal: Grooveshark. You just searcfh for the song you’d like to hear, press play and there you are. If you want to listen to multiple songs, there’s a queue usable without registration. Nice!


NetBeans Community Approves NetBeans 6.7 for Prime Time Release

The NetBeans community acceptance survey has voted for thhe last NetBeans 6.7 RC to be stable enough to be shipped. While this sounds great there is one minor details I consider critical for the significance of the survey: Only 182 people responded. (re-engineneered from 144 people being 79%). If we go with common numbers in empirical research ~5 % of the population take part in survey like these and therefore I conclude that the size of the NetBeans community is around 3.600 people.

NetBeans is actually having quite a a hard time with Eclipse pressing from open source and Idea pressing from commercial alternatives. Also the free IDEs of Microsoft’s .NET family affect the scene. However, I still think that if NetBeans manages to advance from the “I can do all” principle to a small and lean application development environment featuring a fast and intelligent editor and a WYSIWYG gui builder there is definitely a chance.


Americans Viewed a Record 16.8 Billion Videos Online in April Driven Largely by Surge in Viewership at YouTube – comScore, Inc

comScore recently updated their count of videos viewed online. Interesting enough: YouTube and therefore Google leads the market 🙂 For Europeans however a (possibly) large fraction of the video content cannot be accessed any more. Due to missing license agreements many many music videos cannot be watched (at least from within Austria). How does that counteract piracy? 😀

From comScore:

“[…] U.S. Internet users viewed 16.8 billion online videos during the month, representing an increase of 16 percent versus March. A significant increase in video viewing at YouTube during April contributed to the month’s sizeable gains.”

Workshop on Semantic Multimedia Database Technologies (SeMuDaTe 2009)

The workshop is collocated with the 4th International Conference on Semantic and Digital Media Technologies SAMT2009 in Graz, Austria – Dec 2-4, 2009.

Ontology-based systems have been developed to structure content and support knowledge retrieval and management. Semantic multimedia data processing and indexing in ontology- based systems is usually done in several steps. One starts by enriching multimedia metadata with additional semantic information possibly obtained by methods for bridging the semantic gap. Then, in order to structure data, a localized and domain specific ontology becomes necessary since the data has to be interpreted domain-specifically. The annotations are stored in an ontology management system where they are kept for further processing. In this scope, Semantic Database Technologies are now applied to ensure reliable and secure access, efficient search, and effective storage and distribution for both multimedia metadata and data. Their services can be used to adapt multimedia to a given context based on multimedia metadata or even ontology information. Services automate cumbersome multimedia processing steps and enable ubiquitous intelligent adaptation. Both, database and automation support facilitate the ubiquitous use of multimedia in advanced applications.

Topics of interest are how multimedia metadata standards and multimedia ontologies are mapped or integrated into databases, how multimedia query languages are built, and how semantic queries are optimized and processed. Moreover, we are interested how multimedia data services are conceived to ensure interoperability, how to improve security and reliability of access and storage of multimedia data and metadata. Adaptation of multimedia, semantic enrichment of multimedia and bridging of media breaks are typical examples of advanced multimedia database services.

The workshop proceedings will be published as a volume at CEUR Workshop Proceedings. Selected papers will appear in a special issue of a journal. Previous editions of the workshop have selected for instance journals from the Springer Verlag.
