<h1>Incubator Activity</h1>

<p><img align="right" alt="Incubator logo"
src="http://www.w3.org/2005/Incubator/images/incubator.png" /></p>
<ul>
  <li>Targeting <strong>innovative</strong> specs, guidelines, applications
    <ul>
      <!-- <li>Not needing the scrutiny of the Rec track (not likely to become
        foundational Web standards)</li> -->
      <li>Not ready for Rec track (need work, consensus building)</li>
    </ul>
  </li>
  <li>Benefits
    <ul>
      <li><strong>Rapid start</strong> of Incubator Group (XG)</li>
      <li><strong>Rapid finish</strong> within one year</li>
      <li><strong>W3C infrastructure</strong> leveraged</li>
      <li><strong>Consensus-building</strong> within W3C culture</li>
      <li><strong>Smooth <a
        href="http://www.w3.org/2005/Incubator/REC-track.html">transition</a></strong>
        to the <a
        href="http://www.w3.org/2005/10/Process-20051014/tr.html#Reports">W3C
        Rec Track</a>, if desired and approved</li>
    </ul>
    <p></p>
  </li>
</ul>

<div class="slide">
<h1>Possibility for Quick Jump to Rec Track</h1>
<ul>
  <li>Charter development and AC review can be started before XG finishes
    <p></p>
  </li>

<h1>MMSEM: Day to Day</h1>


<ul>
  <li>Duration: May 2006 - May 2007</li>
  <li>29 group participants:</li>
	<ul>
		<li>from 13 organizations</li>
		<li>plus 1 Invited Expert</li>
	</ul>
  <li>Bi-weekly teleconferences</li>
  <li>Face 2 Face meeting
	<ul>
		<li>10-11/07 (CWI, Amsterdam)</li>
		<li>08-09/12 (SAMT-2006, Athens)</li>
	</ul>
  </li>
</ul>
</div>

<div class="slide">
<h1>Mission</h1>
<ul>
  <li>Use SW technologies to integrate existing multimedia metadata standards:
	<ul>
		<li>Leverage and combine existing approaches</li>
	</ul>
  </li>
  <li>Show the added value of the SW formal semantics:
	<ul>
		<li>Practical applications and services that provide extra functionality by using, for example, subsumption reasoning or rule-based approaches</li>
		<li>Multi-platform applications, adapted to any device that accesses the web
		</li>
	</ul>
  </li>
  <li>Provide best practices for annotating and using multimedia content on the Web:
	<ul>
		<li>Practical use cases that identify the users, the type of content and the type of metadata that they want to provide</li>
	</ul>
  </li>
</ul>
</div>


<div class="slide">
<h1>Deliverables</h1>
<ul>
  <li>XG Report on
<a href="http://www.w3.org/2001/sw/BestPractices/MM/image_annotation.html">
Image Annotation on the Semantic Web</a>
    <ul>
      <li>Editor: Jacco van Ossenbruggen, Raphael Troncy, Giorgos Stamou and Jeff Z. Pan</li>
    </ul>
  </li>
  <li>XG Report on using Semantic Web languages and tools for multimedia metadata interoperability
    <ul>
      <li>Editor: Vassilis Tzouvaras</li>
    </ul>
  </li>
  <li>XG Report with use cases showing best practices for annotation multimedia content on the Web and the advantages of having explicit semantics for such annotations.
  </li>
</ul>


</div>

<div class="slide">
<h1>Use Case: Interoperability</h1>


<ul>
  <li><strong>Music Use Case</strong>
    <ul>
      <li>Identify uniquely song vs performance vs CD track (ID3 tags)</li>
      <li>Lyrics aligned with audio (linked with video clip)</li>
      <li>How to find musically equivalent song?</li>
    </ul>
  </li>
<li><strong>Tagging Use Case</strong>
    <ul>
      <li>Identify uniquely tags</li>
      <li>How to reuse tags between heterogeneous system (e.g. Flick vs YourTube)</li>
      <li>Process the existing tags (clouds): towards emergent semantics</li>
    </ul>
  </li>
  <li><strong>News Use Case</strong>
    <ul>
      <li>Identify uniquely news stories</li>
      <li>NewsML G2 architecture: annotation of images (EXIF), videos (MXF, EBU, MPEG-7) + semantics (thesaurus)</li>
    </ul>
  </li>
  <li><strong>MPEG-7 metadata interoperability Use Case</strong>
  </li>
</ul>

</div>

<div class="slide">
<h1>Use Case: Representation</h1>
<ul>
  <li><strong>Algorithm representation Use case</strong>
    <ul>
      <li>Keep trace of all processes, transformations of an image, actions taken in a workflow, etc.</li>
      <li>Needs to define proper ontologies and rules to describe diagnosis, and decision process</li>
    </ul>
  </li>
  <!-- <li><strong>Low level feature extraction Use case</strong>
    <ul>
      <li>Need for semantic interpretation of low level descriptors</li>
      <li>Beyond the representation, the semantic interpretation</li>
    </ul>
  </li> -->
  <li><strong>Bio-medical Image Use Case</strong></li>
</ul>
</div>

<div class="slide">
<h1><strong>MMSEM: Future</strong><br />
</h1>
<ul>
  <li><strong>Possible new Rec Track Working Group on<br /></strong>
  <strong><font color="#333399"><i>Multimedia Annotation Interchange Format</i></font></strong>
    <ul>
      <li>Use SW technologies to integrate existing multimedia metadata standards</li>
      <li>Both deliverables can serve as  starting points of LC</li>
      <li>2nd Face to Face Meeting in Athens (Dec 2006)
        <ul>
          <li>Decide whether to declare intension to move the Rec Track</li>
          <li>Start work on building wider community consensus</li>
          <li>Start drafting WG charter (to be done by March 2007)</li>
        </ul>
      </li>
    </ul>
  </li>
</ul>
