============================ CALL FOR PAPERS ============================

               11th International Conference on
            Electronic Commerce and Web Technologies
                           EC-Web 2010

=========================================================================

EC-Web 2010

After the initial enthusiastic initiatives and investments and the 
eventual bubble, Electronic Commerce has changed and evolved in a 
well established and founded reality both from a technological point 
of view and from a scientific one. Nevertheless, together with its 
evolution, new challenges and topics have emerged as well as new 
questions have raised related to many aspects of Electronic Commerce.

After the lesson learned during last years and following the successful 
edition of EC-Web 2009, for its 11th edition EC-Web will try to provide 
a clearer description of the Electronic Commerce universe focusing on 
some relevant topics. The main focus is not only on Internet related 
techniques and approaches. The aim of EC-Web 2010 is to cover also

Re: Explicit RDF property for "literal has datatype D"?

Sorry for resurrecting this old thread, but I just stumbled upon this:

"rdfs:Datatype is both an instance of and a subclass of rdfs:Class. Each
instance of rdfs:Datatype is a subclass of rdfs:Literal."

"A typed literal is an instance of a datatype class."

citing http://www.w3.org/TR/rdf-schema/#ch_datatype

So I think this is valid:

_:x rdf:type xsd:date .
_:x owl:sameAs "2008-01-01" .

Quite confusing, but might be useful for RDF systems which treat
literals as just one "type" (type from their point of view).

Shame there is no such thing for language tags, or is there?

Best,
Jiri Prochazka

Not as such, did you mean:

  _:x rdf:type xsd:date .
  _:x owl:sameAs "2008-01-01"^^xsd:date .

? Which would, I believe, be valid.

Hi,

  Could you "Describe three different formats in which RDF documents can be
expressed"?

RDFa, RDF/XML and Turtle. But was it  really not easy to find this out  
from searching or reading Wikipedia?

Call For Papers

ELEVENTH INTERNATIONAL WORKSHOP ON
RULE-BASED SPECIFICATION AND PROGRAMMING

RULE-BASED PROGRAMMING IN INDUSTRY AND THE SEMANTIC WEB

Edinburgh, UK
July 14, 2010

This CFP' URL:
http://www.di.uminho.pt/rule2010

(Workshop affiliated to FLoC 2010 as post-conference event of RTA 2010)

With the renewed interest in rule-based computing for industrial
applications (e.g., Business Rules) especially as it relates to the
Semantic Web ( e.g., the W3C's Rule Interchange Format), it is timely
to explore the practical benefits delivered by computing with rules and
ontologies in the large. Thus, this year's theme will focus on rule-based
programming in Industry and the Semantic Web. The emphasis will be on
implemented systems that have been actually used in pragmatic situations
where the advantages of rule-driven computation and inference have made
all the difference, such advantages being:

* agility
* declarativeness
* maintainability
* documentability
* scalability
* meta-programmability
* reliability
* formal semantics
* etc., ...

In terms of the Semantic Web, we explicitly call for submissions that
probe (in a pragmatic setting) how rule-based approaches complement
ontology-based approaches, which share some of the characteristics of
rule systems, such as declarativeness and formal semantics.

PAPER SUBMISSION

We are solliciting papers dealing with topics related to this year's
theme discussing any or several of the itemized facets of the
combinations of rules and ontologies, going beyond academic experiments
and meant for large-scale or industrial applications. Papers should
contain no more than 10 pages, including figures, and submitted through
EasyChair using the standard EPTCS LaTeX style file.

CFP: Semantics of Visual Objects <at> WWW 2010

- Apologies for cross-posting -

******************* PRELIMINARY CALL FOR PAPERS ***********************

The First Workshop on the Semantics of Visual Objects (SemVO 2010)

Co-Located with the Nineteenth International World Wide Web Conference
(WWW2010), in Raleigh, North Carolina, USA,  April 27, 2010 (morning).

Topics and Content
-------------------

Visual representations (charts, graphs, diagrams) of heterogenous data
(numeric trends, social networks, molecular structures) play an
important role in human communication. Yet most of the visual objects
(VOs) published on the World Web Web are only available as
unstructured raster images, thus depriving us of the ability to
explore and query their contents. This workshop aims to expose raw
data contained within VOs (maintaining the visual information) using
Semantic Web technologies so as to facilitate interoperability, data
sharing, granular annotation, common visual rendering and ultimately,
question answering and knowledge discovery.

Topics of interest:

 - Automatic and manual representation of visual of objects with RDF and OWL
 - Information extraction and integration
 - Rich media and granularity of data representation
 - Natural-language-based semantics for visual scenes
 - Spatial and temporal logics for reasoning with VOs
 - Querying visual objects
 - Domain-specific query languages for VO knowledgebases
 - Complexity of reasoning with visual objects
 - Architectures for storing and querying over large numbers of VOs
 - VO-based web services and service oriented computing
 - Ontologies and terminologies of VOS
 - Templating and dynamic interfaces for searching VOs
 - Evaluation methodologies for VO annotation and search

Workshop Format and Attendance:
-------------------

This will be a half day workshop, including two highlight presentations,
technical talks and demonstrations on Semantic Web enabled visual objects.

Workshop Chair
-------------------

 - Michel Dumontier (Carleton University, Canada) [michel_dumontier <at> carleton.ca]
 - Leo Ferres (Universidad de Concepcion, Chile)  [leo <at> inf.udec.cl]

Program Committee
-------------------

TBA

Important Dates
-------------------

* SUBMISSIONS

 - Deadline for long and short papers: February 15, 2010

 - Notification of acceptance: March 15, 2010

 - Camera-ready: April 1, 2010

 - Workshop: April 27, 2010 (morning)

(All times Midnight Hawaii Standard Time)

More details:
http://semanticscience.org/workshop/semvo2010/

Submissions
-------------------

Authors are invited to submit original contributions of practical relevance
and technical rigor, experience reports, and show case / use case
demonstrations
of effective, practical technologies or applications in applying semantic
technologies to visual objects.

Papers must be in English and may be submitted at
http://www.easychair.org/conferences/?conf=semvo2010 as:

-   Full Papers (10 pages)
-   Short Papers (4 pages)
-   Position Statements (2 pages)

Please upload all submissions as PDF files in LNCS format
(http://www.springer.de/comp/lncs/authors.html). Submissions will be
peer-reviewed
by at least 3 PC members based on originality, significance, technical
soundness,
and clarity of exposition.

Publication details will be posted to the workshop web site,
http://semanticscience.org/workshop/semvo2010/, as they become available.

Re: Explicit RDF property for "literal has datatype D"?

Hmm I guess you are right
(http://www.w3.org/TR/rdf-concepts/#section-Literal-Equality).
I guess some property would have to be created:

_:x rdf:type xsd:date .
_:x todo:value "2008-01-01" .

todo:value rdfs:domain rdfs:Literal . # well, typed literal, no such
					class exists (yet)
todo:value rdfs:range rdfs:Literal . # well, plain literal :)

that should be equivalent to saying:

_:x owl:sameAs "2008-01-01"^^xsd:date .

Best,
Jiri
