1st CFP: IJCAI-11 Workshop on Discovering Meaning On the Go in Large & Heterogeneous Data (LHD-11)

Apologies for cross-posting

------------------------------------------------------------------------------
Call for papers for LHD-11 workshop at IJCAI-11, July 2011, Barcelona:

Discovering Meaning On the Go in Large & Heterogeneous Data

http://dream.inf.ed.ac.uk/events/lhd-11/
------------------------------------------------------------------------------

An interdisciplinary approach is necessary to discover and match meaning
dynamically in a world of increasingly large data.  This workshop aims
to bring together practitioners from academia, industry and government
for interaction and discussion.  The workshop will feature:

*  A panel discussion representing industrial and governmental input,
entitled "Big Society meets Big Data: Industry and Government
Applications of Mapping Meaning".  Panel members will include:
 *  Peter Mika (Yahoo!)
 *  Alon Halevy (Google)
 *  Tom McCutcheon (Dstl)
 *  (tbc)
*  An invited talk from Fausto Giunchglia, discussing the relationship
between social computing and ontology matching;
*  Paper and poster presentations;
*  Workshop sponsored by: Yahoo! Research, W3C and others

Workshop Description

The problem of semantic alignment - that of two systems failing to
understand one another when their representations are not identical -
occurs in a huge variety of areas: Linked Data, database integration,
e-science, multi-agent systems, information retrieval over structured
data; anywhere, in fact, where semantics or a shared structure are
necessary but centralised control over the schema of the data sources is
undesirable or impractical. Yet this is increasingly a critical problem
in the world of large scale data, particularly as more and more of this
kind of data is available over the Web.

In order to interact successfully in an open and heterogeneous
environment, being able to dynamically and adaptively integrate large
and heterogeneous data from the Web "on the go" is necessary. This may
not be a precise process but a matter of finding a good enough
integration to allow interaction to proceed successfully, even if a
complete solution is impossible.

Considerable success has already been achieved in the field of ontology
matching and merging, but the application of these techniques - often
developed for static environments - to the dynamic integration of
large-scale data has not been well studied.

Presenting the results of such dynamic integration to both end-users and
database administrators - while providing quality assurance and
provenance - is not yet a feature of many deployed systems. To make
matters more difficult, on the Web there are massive amounts of
information available online that could be integrated, but this
information is often chaotically organised, stored in a wide variety of
data-formats, and difficult to interpret.

This area has been of interest in academia for some time, and is
becoming increasingly important in industry and - thanks to open data
efforts and other initiatives - to government as well. The aim of this
workshop is to bring together practitioners from academia, industry and
government who are involved in all aspects of this field: from those
developing, curating and using Linked Data, to those focusing on
matching and merging techniques.

Topics of interest include, but are not limited to:

* Integration of large and heterogeneous data
* Machine-learning over structured data
* Ontology evolution and dynamics
* Ontology matching and alignment
* Presentation of dynamically integrated data
* Incentives and human computation over structured data and ontologies
* Ranking and search over structured and semi-structured data
* Quality assurance and data-cleansing
* Vocabulary management in Linked Data
* Schema and ontology versioning and provenance
* Background knowledge in matching
* Extensions to knowledge representation languages to better support change
* Inconsistency and missing values in databases and ontologies
* Dynamic knowledge construction and exploitation
* Matching for dynamic applications (e.g., p2p, agents, streaming)
* Case studies, software tools, use cases, applications
* Open problems
* Foundational issues
Applications and evaluations on data-sources that are from the Web and
Linked Data are particularly encouraged.

Submission

LHD-11 invites submissions of both full length papers of no more than 6
pages and position papers of 1-3 pages. Authors of full-papers which are
considered to be both of a high quality and of broad interest to most
attendees will be invited to give full presentations; authors of more
position papers will be invited to participate in "group panels" and in
a poster session.

All accepted papers (both position and full length papers) will be
published as part of the IJCAI workshop proceedings, and will be
available online from the workshop website. After the workshop, we will
be publishing a special issue of the Artificial Intelligence Review and
authors of the best quality submissions will be invited to submit
extended versions of their papers (subject to the overall standard of
submissions being appropriately high).

All contributions should be in pdf format and should be uploaded via
http://www.easychair.org/conferences/?conf=lhd11. Authors should follow

Regarding complation process of ambulant-2.2.tar on Win XP

 Can anyone help me out in compiling ambulant-2.2.tar on Win XP ? The
problems I am facing while I am trying to compile Ambulant-win32.sln under
ambulant-2.2\projects\vc8-smil3 is that, I find it gives linking erros for
certain .lib files it does NOT find. How can I solve this problem ? Is there
any download which will have all the necessay third_party_packages bundled
up in one package ?

Events when adding and removing animation elements in play

Dear all,

I wish to clarify the expected behaviour of animations that are
dynamically removed and added from a document with regards to the
events that are generated.

Suppose an animation is in play when it is temporarily removed from
the document. Later, that same animation is re-attached to the
document. In the meantime however, the time of the document (or, more
accurately, the time container) may have changed either through
seeking the document or simply due to the wallclock time that has
elapsed.

When the animation is re-attached it must either catch-up or wind back
to the document time. However, just how this should be done is not, so
far as I know, specified.

Some options include:

1) When the element is removed, all information regarding the
animation's progress is lost. Re-attaching effectively performs a kind
of forwards-seek on the animation.

2) Animation progress is retained and when the element is re-attached
either a forwards or backwards seek is performed as required.

Personally, I think (1) is more intuitive, particularly as the element
may be re-attached to a different time container altogether.

However, regardless of which it is, there is still the question of the
nature of the seek. Generally, when seeking is performed most events
that would otherwise be generated along the way are suppressed.[1] So,
is attaching an element a genuine seek in that sense or should all
events still be generated? My feeling is that they should still be
generated.

Thus for the attached example which I've simplified below:

<svg>
  <script>
    function seek()
    {
      svg.setCurrentTime(11);
      circle.removeChild(animate);
      svg.setCurrentTime(7);
      circle.appendChild(animate);
    }
    document.addEventListener("SVGLoad", seek, true);
  </script>
  <circle ...>
    <animate begin="2s; 6s; 10s" dur="2s" id="animate" .../>
  </circle>
</svg>

My understanding is that we should get:

* 1 x beginEvent as a result of the initial seek to t=11s (as per my
interpretation of [1])
* 2 x beginEvent as a result of re-attaching the animation element
(which will drive the animation through begin times 2s and 6s)

Then after 3s,
* 1 x beginEvent when the third interval begins (at t=10s)

Another issue is whether detaching an animation that is in play should
generate an endEvent. Personally I think it should not since otherwise
a lot of events would be generated on document teardown unless
implementations differentiate between these two situations
(script-based removal and document teardown).

Any thoughts here would be greatly appreciated.

Best regards,

Brian Birtles

I 1st ran it with Ambulant Player 2.02 and then by 2.2 on Win XP. My
observations were the following a)Ambulant player 2.02 - It displays only
the 1st string "You should see this from 1 to 5 seconds."
b)Ambulant player 2.2  - It displays both the string namely
									
"You should see this from 1 to 5 seconds."  Followed by
"You should see this from 10 to 20 seconds."

Q1)Why do we have different outputs for 2 different versions of Ambulant
player ?

Q2)Suppose I do the following changes while running it from 2.2 player

     <setvalue begin="5s" ref="foo" value="42"/>  --- Retain this line
     <setvalue begin="5s" ref="bar" value="43"/>  --- delete this line
     <setvalue begin="5s" ref="foo" value="44"/>  --- delete this line 
     <setvalue begin="5s" ref="bar" value="45"/>  --- delete this line		

The expected behavior would have been that only the 1st string, should have
been displayed as variable "foo" would have been set and this would have
resulted in mystate.stateChange(foo) being set to true.

However, both the strings, namely
 "You should see this from 1 to 5 seconds." Followed by  
 "You should see this from 10 to 20 seconds."

are displayed.

If variable "bar" is not set at all, then how is it that
mystate.stateChange(bar) variable is set to true for the 2nd string to be
displayed ?

Strange use of SMIL 3.0 in Wikimedia video sequencer ?

Dear SMIL and WikiMedia folks, I wanted to bring this to your attention:

The HTML5-driven Wikimedia "sequencer" - a template-based online video  
editor - stores the EDL (Edit Decision List) in the SMIL format.  
There's a recent introductory blog post [1] about it.

You can see an example for yourself by opening this page [2] with  
Firefox 4 (preferably), by clicking on "Edit Sequence", then by  
clicking on the "View" button in the upper-left corner, followed by  
"Sequence SMIL XML" from the popup menu. The SMIL 3.0 source will be  
revealed. For convenience, I quoted the XML source at the bottom of  
this email.

This appears to be a custom version of what I would normally qualify  
as SMIL, at least (as far as I can tell) not something based on the  
normative Scalability Framework [3], nor based on an existing subset  
of SMIL (see Modularization and Profiling [4]).

For example, the format overrides the normal SMIL namespace for "img"  
and "ref" with xmlns="http://www.w3.org/1999/xhtml", although I'm a  
bit confused as I can't see any XHTML constructs there. There's a  
combination of XML attribute name/value pairs coming from SMIL a well  
as from some domain-specific markup (none of which seem to belong to  
the specified namespace). The format also injects arbitrary parameters  
into media objects using nested "param" tags (and  "name" + "value"  
pairs), thereby adding another layer of extensibility (why mix native  
attributes and the param element ?).

I am wondering whether there is scope in this "lab" project to discuss  
the EDL syntax ? It would be great if the final format was compatible  
with SMIL user agents (playback engines and production tools). I am  
sure that simple changes could be made to "clean-up" the namespaces  
and to define an XML schema that draws the boundaries between SMIL and  
domain-specific markup.

The statement from the blog "The SMIL spec has evolved over time and  
has become famous for being very large and complicated to implement in  
a real world player" may be true for the specification as a whole, but  
not for a domain-specific subset ;)  Just look at SVG or DAISY as  
prime examples of standards that integrate only the strictly-necessary  
parts of SMIL.

The claim that "Another nice feature of SMIL xml is that it is  
extensible for custom components" may be true indeed, but this is not  
quite achieved with the proposed format, as it doesn't conform to the  
extensibility guidelines.

I am looking forward to hearing your thoughts. Feel free to correct me  
if I got something wrong ! :)

I assume the "public-smil" and "wikivideo-l" mailing lists are most  
appropriate to continue this discussion, but I also CC'ed the more  
mature WikiMedia technical lists to ensure this message reaches "whom  
it may concern" :)
