Call for participation for SWCS2012@WWW2012

Semantic Web Collaborative Spaces Workshop  at
  the 21st International World Wide Web Conference.
Tuesday April 17th, 2012 in Lyon - France - 9H
========================================

== Goal and Motivations ==

Semantic Web Collaborative Spaces such as semantic wikis, semantic social
networks, semantic forums, etc. are social semantic software with the
mission to bring together human agents and software agents in order to
foster knowledge-intensive collaboration, content creation and management,
annotated multimedia collection management, social knowledge diffusion and
formalising, and more generally speaking ontology-oriented content
management life-cycle.

The domain spans from multidisciplinary research to deployed commercial web
applications and contributions from all this spectrum are encouraged. The
aim of the SWCS 2012 workshop is to exchange ideas, to discuss pressing
research questions arising from theoretical studies and practical usage of
semantic web collaborative spaces.

09:00 - 09:40 Keynote: *Wikidata: A new platform for collaborative data
collection* *Denny Vrandečić<http://www.aifb.kit.edu/web/Denny_Vrandecic/en>,
*

*
Abstract: *This year, Wikimedia starts to build a new platform for the
collaborative acquisition and maintenance of structured data: Wikidata.
Wikidata's prime purpose is to be used within the other Wikimedia projects,
like Wikipedia, to provide well-maintained, high-quality data. The nature
and requirements of the Wikimedia projects require to develop a few novel,
or at least unusual features for Wikidata: Wikidata will be a secondary
database, i.e. instead of containing facts it will contain references for
facts. It will be fully internationalized. It will contain inconsistent and
contradictory facts, in order to represent the diversity of knowledge about
a given entity.



09:40 - 10:00 *Linking Justifications in the Collaborative Semantic Web
Applications, *Rakebul Hasan and Fabien Gandon.

*Abstract: *The collaborative Semantic Web applications produce ever
changing interlinked Semantic Web data. The applications that utilize these
data to obtain their results should provide explanations about how the
results are obtained in order to ensure the effectiveness and increase the
user acceptance of these applications. Justifications providing meta
information about why a conclusion has been reached enable generation of
such explanations. We present an encoding approach for justifications in a
distributed environment focusing on the collaborative platforms. We discuss
the usefulness of linking justifications across the Web. We introduce a
vocabulary for encoding justifications in a distributed environment and
provide examples of our encoding approach.


10:00 - 10:20 *User Assistance for collaborative knowledge construction*,
Pierre-Antoine Champin, Amélie Cordier, Élise Lavoué, Marie Lefevre and
Hala Skaf-Molli.

*Abstract:* In this paper, we study tools for providing assistance to users
in distributed spaces. More precisely, we focus on the activity of
collaborative construction of knowledge, supported by a network of
distributed semantic wikis. Assisting the users in such an activity is made
necessary mainly by two factors: the inherent complexity of the tools
supporting that activity, and the collaborative nature of the activity,
involving many interactions between users. In this paper we focus on the
second aspect. For this, we propose to build an assistance tool based on
users interaction traces. This tool will provide a contextualized
assistance by leveraging the valuable knowledge contained in traces. We
discuss the issue of assistance in our context and we show the different
types of assistance that we intend to provide through three scenarios. We
highlight research questions raised by this preliminary study.


10:20 - 10:30 *Man-machine collaboration to acquire adaptation knowledge
for a case-based reasoning system,* Amélie Cordier, Emmanuelle Gaillard and
Emmanuel Nauer. *(short presentation)*

*Abstract: *This paper shows how humans and machines can better collaborate
to acquire adaptation knowledge (AK) in the framework of a case-based
reasoning (CBR) system whose knowledge is encoded in a semantic wiki.
Automatic processes like the CBR reasoning process itself, or specific
tools for acquiring AK are integrated as wiki extensions. These tools and
processes are combined on purpose to collect AK. Users are at the center of
our approach, as they are in a classical wiki, but they will now benefit
from automatic tools for helping them to feed the wiki. In particular, the
CBR system, which is currently only a consumer for the knowledge encoded in
the semantic wiki, will also be used for producing knowledge for the wiki.
A use case in the domain of cooking is given to exemplify the man-machine
collaboration.


10:30 - 11:00 Coffee

11:00 - 11:20 *Building Consensus via a Semantic Web Collaborative Space*,
George Anadiotis, Konstantinos Kafentzis, John Pavlopoulos and Adam
Westerski.

*Abstract:* In this paper we outline the design and implementation of the
eDialogos Consensus process and platform to support wide-scale
collaborative decision making. We present the design space and choices made
and perform a conceptual alignement of the domains this space entails,
based on the use of the eDialogos Consensus ontology as a crystallization
point for platform design and implementation as well as interoperability
with existing solutions. We also present a
metric for calculating agreement on the issues under debate in the
platform, incorporating argumentation structure and user feedback.

11:20 - 11:40 *Knowledge Continuous Integration Process (K-CIP)*, Hala
Skaf-Molli, Pascal Molli, Emmanuel Desmontils, Emmanuel Nauer, Yannick
Toussaint, Gérôme Canals, Amélie Cordier and Marie Lefevre.

*Abstract:* Social semantic web opens interesting perspectives for
man-machine collaboration. It creates read/write spaces where users and
smart agents can collaborate to produce knowledge readable by humans and
machines. However, this process is not always safe, especially because many
unpredictable errors can occur when knowledge is modified online. In this
paper, we propose to implement a continuous knowledge integration process
named K-CIP. We take advantage of man-machine collaboration to transform
feedback of people into tests. This paper presents how K-CIP can be
deployed to allow fruitful man-machine collaboration in the context of the
WikiTaaable system.

 11:40 - 12:00 *Improving Wikipedia with DBpedia,* Diego Torres, Pascal
Molli, Hala Skaf-Molli and Alicia Diaz.

*Abstract:* DBpedia is the semantic mirror of Wikipedia. DBpedia extracts
information from Wikipedia and stores it in a semantic knowledge base. This
semantic feature relies in making complex queries inferring relations among
articles which sometimes are missing in Wikipedia. This difference
generates an information gap between DBpedia and Wikipedia. Could be
improved Wikipedia with DBpedia new information to reduce this gap? How
this new information should be added to Wikipedia? In this article, we
propose a path indexing algorithm (PIA) who takes a data set of a DBPedia
query and returns the best representative path to be applied in the
Wikipedia. We evaluate the results of applying PIA to express the relation
between people and their birth city.


12:00 - 12:20 *Synchronizing semantic stores with Commutative Replicated
Data Types,* Luis Daniel Ibáñez, Hala Skaf-Molli, Pascal Molli and Olivier
Corby.

*Abstract:* Social semantic web technologies led to huge amounts of data
and information being available. The production of knowledge from this
information is challenging, and ma- jor efforts, like DBpedia, has been
done to make it reality. Linked data provides interconnection between this
informa- tion, extending the scope of the knowledge production. The
knowledge construction between decentralized sources in the web follows a
co-evolution scheme, where knowledge’s generated collaboratively and
continuously. Sources are also autonomous, meaning that they can use and
publish only the information they want. The updating of sources with this
criteria is intimately re- lated with the problem of synchronization, and
the consis- tency between all the replicas managed. Recently, a new family
of algorithms called Commutative Replicated Data Types have emerged for
ensuring eventual consistency in highly dynamic environments. In this
paper, we define SU-Set, a CRDT for RDF-Graph that supports SPARQL Update
1.1 operations.

 12:20 - 12:30 *Community: Issues, definitions, and operationalization on
the web,* Guo Zhang and Elin K. Jacob *(short presentation)*

*Abstract: *This paper addresses the concepts of community and online
community and discusses the physical, functional, and symbolic
characteristics of a community that have formed the basis for traditional
definitions. It applies a four-dimensional perspective of space and place
(i.e., shape, structure, context, and experience) as a framework for
refining the definition of traditional offline communities and for
developing a definition of online communities that can be effectively
operationalized. The methods and quantitative measures of social network
analysis are proposed as appropriate tools for investigating the nature and
function of communities because they can be used to quantify the typically
subjective social phenomena generally associated with communities.
