Knowledge Media Institute, Berrill Building, The Open University, Milton Keynes, United Kingdom, MK7 6AA
This talk consists of two parts: the first part focusses on a study of the dynamics of online peer production systems; the second discusses crowdsourcing strategies to semantically structure a large body of knowledge.
Despite a large interest in the research community for online peer production, little has been done to study the dynamics of online communities that form part of larger ecosystems, and in particular what determines the performance and ultimately the survival of individual collaborative communities within such an ecosystem. This is partly due to the lack of large-scale data on the temporal evolution of collaborative ecosystems, partly to a poor understanding of what it means for communities that form these ecosystems to be "viable". Studying how these communities evolve over time can help us understand the determinants of their growth and assess their viability as a function of their social structure, internal functioning and relationship with competing communities. In this talk I present two case studies looking at community dynamics in the context of the wiki and social media ecosystem. I also present a tool called WikiTracer whose goal is to help us collect in a standardised way detailed data on wiki-based communities from a variety of heterogeneous platforms.
The second part of this presentation describes the CrowdLinks project, a proposed framework to allow large populations of users to semantically annotate the relationship between scholarly articles. Online reference management services offer a unique opportunity to add a collaborative semantic layer on top of a citation network. In this talk I present the rationale, design and expected outcome of this framework and discuss how collaborative citation typing can help us better understand the structure and progress of scientific research. |
