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. <http://www.few.vu.nl/soks/_detail/david.png?id=symposium>*David Chavalarias* /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. <http://www.few.vu.nl/soks/_detail/siegfried.png?id=symposium>*Siegfried Handschuh* /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. <http://www.few.vu.nl/soks/_detail/philippe.png?id=symposium>*Philippe Cudré-Mauroux* /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. <http://www.few.vu.nl/soks/_detail/kia.png?id=symposium>*Kia Teymourian* /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. Please, feel free to forward this message to anyone you think might find it interesting. Best regards, Christophe Guéret
