* Apologies for cross-posting * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CFP: Workshop on Interdependent Networks: Quality, Influence and Evolution in Social and Information Networks (WIN2011) at the 22nd ACM Hypertext 2011 which will be held in Eindhoven, NL on June 6-9 2011. Website: https://sites.google.com/site/ht2011win/ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The emergence of new social technologies has not only changed our everyday life but also has led to new forms of collective information goods such as media collections, commentary and software. Innovative online production systems have been designed for people to share their ideas, their experiences and their knowledge enabling the collaborative production of such information goods. The nature of these collective information goods produced using online production systems ranges from pooled information (e.g., Flickr, del.icio.us, Slashdot) to structured information (e.g., Wikipedia, Factual.com), and tightly coupled information (e.g., open source software). This spectrum describes both the coupling of the components of an information good as well as to what extent certain coordination, communication and collaboration processes between participants were required to develop this good. Concretely, these information goods consist of a social dimension which comprises links between people based on their interactions and the information dimension which are links based on syntactic, semantic or logical relations within these goods. Thus, to effectively understand collective information goods, one must take a multi-dimensional approach that addresses the interdependence between social relationships and the networked information that those relationships produce. Only recently have researchers begun to study the collective information goods using multi-dimensional approaches. This workshop aims to bring together experts in network analysis, information networks, semantics and social media to further the development and exchange of knowledge around computational network analysis methods for multi-dimensional networks. We are particularly interested in work that convers the following three areas: * Quality - how do we measure quality of a collective information good using network analysis? What is the relationship between quality information and reputation? How do online production systems cater for quality? * Influence - how do we measure the influence of information networks on social networks and vice versa? Are types of networks more influential than others? * Evolution - how do information and social networks co-evolve? What techniques can be used for measuring and describing evolution? +++Topics include+++ * Models of influence in social media including Twitter, Facebook and others * Measures and techniques for assessing quality in online production systems such as reputation systems in Wikipedia * Measures and techniques for assessing influence in online production systems * Empirical studies of influence, quality and evolution in social media * Approaches towards influencing users and quality in online production systems * (Co-)evolution of social and information networks * Network visualizations of quality, influence and evolution +++Important Dates+++ April 1, 2011: Submission Date April 29, 2011: Notification Date May 10, 2011: Early conference registration deadline June 6, 2011: Workshop Date +++Contributions+++ We invite paper submissions consisting of original, unpublished research that is not under review by another conference, journal, or workshop.
