MediaMixer is pleased to announce its tutorial on “re-using media on the Web” has been accepted for the program of the World Wide Web Conference 2014, taking place in Seoul, Korea in April 7-11 2014.

This will be an opportunity for Web developers and media professionals to receive direct, hands-on experience in using MediaMixer technologies  to annotate and interlink online media fragments to support new applications.

Register now to ensure your place. Full registration (with conference) or discounted registration (for workshops and tutorials only) options are available.


Topic and description of the tutorial

This tutorial will address the state of the art in the area of online media analysis, annotation and
linking, reflecting that a number of Web-based specifications and technologies are now emerging
that in combination can provide the technical solution for media owners to be enabled to manage
and re-use their online media at a fragment level.

Alone the need to raise the visibility of these individual Web-based specifications and technologies,
part of the remit of the MediaMixer project which will support this tutorial, would motivate the
tutorial for researchers and practitioners in the multimedia domain: the W3C Media Fragment
specification offers a chance to have a standard URL-based expression for media fragments across
the Web, the W3C Media Ontology and Open Annotation Models with their fragment re-use
specific extensions in projects like LinkedTV offer the possibility of interchangable and machine
reusable semantic media descriptions across repositories, , support for media fragments and the
related specifications needs to be built into multimedia search and retrieval systems and HTML5-
based media playout technology with the first early adopters being visible. On top of this, the
combination of these specifications and technologies can form a full online media workflow able to
support media fragmentation and re-use, which opens means to derive new value from media to
media owners and new models for media acquisition and use for media consumers. Hence the
awareness of and ability to use these specifications and technologies will be of great importance to
future curators and publishers of online media.

Intended audience

The target audience is researchers from the different areas of Web multimedia research that deal
with the analysis, organization and indexing of online multimedia content, with an interest of being
enabled to better do so at fragment level, as well as developers of novel applications for the re-use
and re-mixing of media fragments which can be of benefit to media owners, providers and
consumers. The participants of the tutorial will gain an insight into the current state-of-the-art of
research on multimedia fragments and remixing. The participants will also have the opportunity to
hands-on use different tools for the purpose and create their own media re-mix.


Our tutorial is focused on intermediate skilled Web media researchers and professionals. It will
assume a basic knowledge in the principles around media analysis, annotation, management, search
and presentation but not assume the use of any specific technologies or standards.

Duration and program

We plan a half day tutorial of three one hour blocks plus breaks.

Session 1: Media fragment analysis and creation
Speaker: Vasileios Mezaris (CERTH)
Summary: Explain approaches to visual, audio and textual media analysis to automatically
generate meaningful media fragments out of a media resource. Demonstrate latest results in the
areas of video fragmentation, visual conceopt and event detection, face detection, object redetection,
and the use of speech recognition and keyword extraction from text for supporting
multimedia analysis.
Session 2: Media fragment specification and semantics
Speaker: Benoit Huet (EURECOM)
Summary: Introduce the W3C Media Fragment URI specification. Highlight how media fragments
can be incorporated into known media description schema, with a focus on the W3C Media
Ontology and the Open Annotation Model. Extensions to these ontologies to more richly link
media fragments to the concepts they represent.
Session 3: Media fragment re-mixing and playout
Speaker: Lyndon Nixon (MODUL)
Summary: A number of novel application ideas will be introduced based on the media fragment
creation, specification and rights management technologies. Semantic search and retrieval allows
us to organize sets of fragments by topical or conceptual relevance. These fragment sets can then
be played out in a non-linear fashion to create a new media re-mix. We look at a server-client
implementation supporting Media Fragments, before allowing the participants to take the sets of
media they have selected and create their own re-mix.
