Abstract-Collaborative systems require access control to prevent unauthorised access and change. Access control has a number of issues, including administration and maintenance overheads. In this paper we argue that it is time to reconsider how access controls work, particularly with scientific and data related domains, and to this end we propose a new paradigm based on a user's demographics and behaviour, rather than simply their identity. In essence, it is both who you are and what you do that is important. We introduce GRAft, our Generalised Recommendation Architecture that allows us to support a range of different recommendation models, and provide case studies to illustrate the usefulness of our architecture.

Abstract-Social clouds are a relatively new paradigm that allow users of an underlying social network to share their resources with their "friends", using previously established relationships. However, this sharing has a number of issues, including granularity of friendships, resource costs and maintenance. In this paper we argue that sharing decisions should be based on relationship information augmented by supplementary metadata derived from multiple sources. Users should be able to leverage the information available on their non-uniform friend relationships when making decisions, allowing them to confidently share their resources with those that would normally be outside of their immediate social circle. We introduce GRAft, our Generalised Recommendation Architecture, that provides us with a mechanism to support this new approach.

“…The elements selection and its assignment of weights were based on CIBO moderators' experience. Our members upgrading or downgrading is done using a social reputation [21]; users obtain higher reputation in the community by having accurate contributions and receiving credits from other users. Users can be upgraded to collaborators.…”

Abstract. Bibliographic digital libraries play a significant role in conducting research and, in the past few years, have started to move from closed to more open social platforms. However, in this, they have faced challenges (e.g., from Web spam) in maintaining the level of scholarly precision-the ratio of relevant citations retrieved by search. This paper describes a hybrid approach that uses online social collaboration and reputation based social moderation to reduce the cost and to speed up the construction of scholarly bibliographies that are comprehensive, have better quality citations and higher precision. We implemented selected social features for an established digital humanities project (the Cervantes Project) and compared the results with a number of closed and open current bibliographies. We found this can help in building scholarly bibliographies and significantly improve precision outcomes.
