Talks from the symposium on Self-organisation in Knowledge Systems (SOKS), April 28-29 2010, Amsterdam

Dear all,

The video of the presentations David Chavalarias, Siegfried Handschuh, 
Philippe Cudré-Mauroux and Kia Teymourian gave at the SOKS Symposium in 
April 2010 (http://www.few.vu.nl/soks/symposium) are now online 
(http://videolectures.net/soks2010_amsterdam/)
If you missed the event but are interested in Self organisation in 
Knowledge systems, this is an opportunity to hear more about it.

/Data trails reconstruction at the community level in the Web of data/
Socio-semantic networks continuously produce data over the Web in a time 
consistent manner. From scientific communities publishing new findings 
in archives to citizens confronting their opinions in blogs, there is a 
real challenge to reconstruct, at the community level, the data trails 
they produce in order to have a global representation of the topics 
unfolding in these public arena. We will present such methods of 
reconstruction in the framework of co-word analysis, highlighting 
perspectives for the development of innovative tools for our daily 
interactions with their productions.

/Social Semantic Collaboration with the Desktop/
The Social Semantic Desktop, defines a user's personal information 
environment as a source and end-point of the Semantic Web: Knowledge 
workers comprehensively express their information and data with respect 
to their own conceptualizations. This covers the aspects of social 
semantics and meta-data creation.

/Emergent Semantics/
Emergent semantics refers to a set of principles and techniques 
analyzing the evolution of decentralized semantic structures in large 
scale distributed information systems. Emergent semantics approaches 
model the semantics of a distributed system as an ensemble of 
relationships between syntactic structures.
They consider both the representation of semantics and the discovery of 
the proper interpretation of symbols as the result of a self-organizing 
process performed by distributed agents exchanging symbols and having 
utilities dependent on the proper interpretation of the symbols. This is 
a complex systems perspective on the problem of dealing with semantics.

/Self-organization in Distributed Semantic Repositories/
Principles from nature-inspired selforganization can help to attack the 
massive scalability challenges in future internet infrastructures. We 
researched into ant-like mechanisms for clustering semantic information. 
We outline algorithms to store related information within clusters to 
facilitate efficient and scalable retrieval.
At the core are similarity measures that cannot consider global 
information such as a completly shared ontology. Mechanisms for 
syntax-based URI-similarity and the usage of a dynamic partial view on 
an ontology for path-length based similarity are described and 
evaluated. We give an outlook on how to consider application specific 
relations for clustering with a usecase in geo-information systems.
