The Scholarly Infrastructure Technical Summit @ eResearch Australasia 2011

Scholarly Infrastructure Technical Summit (SITS) meetings are designed to share technical operational experience between CTOs, Lead Developers and Head System Administrators so as to assure that internationally we are all DRY (Don't Repeat Yourself) i.e. saving technical operational money by learning from each other's previous experiences.Iteration four of the International Scholarly Infrastructure Technical Summit meeting following events in London and California and Geneva took place in Australia alongside the 2011 eResearch Conference (eXtreme eResearch).The eResearch conference brings together CTOs and CIOs from various Universities whose job it is to provide, work with and support IT services for scientific research projects. This was a first for SITS, which previously had seen a mix of researchers and those working on the fringes of institutional IT infrastructure. The Australian focus on supporting research directly thus provided the 4th new platform for the SITS meetings, one closest to the infrastructure itself

Building Social Networks from Institutional Repositories

An Institutional Repository may offer .a set of services. to its local users, supporting the publication of research. More importantly, the repository also forms a key component in the global scholarly communications environment. In this presentation we investigate the role of the repository on a global scale by witnessing the effects on a changing economy and also show how worldwide collaboration networks can be predicted using the strong social links found in repository metadata

Using the Co-Citation Network to Indicate Article Impact

Scholarly outputs are growing in number and frequency, driving the requirement to research new early indication metrics. Historically, citations have been used as an independent indication of the significance of scholarly material. However, citations are very slow to accrue since they can only be made by subsequently published material. This enforces a delay of a number of years before the citation impact of a publication can be accurately judged. Existing early indication metrics, such as download metrics and web based link analysis, have obtained correlation results. Brody finds a good correlation between download metrics and subsequent impact by citation, while Thelwall finds very little correlation between Google's PageRank and the number of links (or citations) to a web site, suggesting neither is a good surrogate indicator for the other. While valid studies, neither take account of the quality assessment factor of peer-review citation. This work presents an investigation into new metrics which utilize the co-citation network in order to rate a publications impact

Releasing the Power of Digital Metadata: Examining Large Networks of Co-Related Publications

Bibliographic metadata plays a key role in scientific literature, not only to summarise and establish the facts of the publication record, but also to track citations between publications and hence to establish the impact of individual articles within the literature. Commercial secondary publishers have typically taken on the role of rekeying, mining and analysing this huge corpus of linked data, but as the primary literature has moved to the world of the digital repository, this task is now undertaken by new services such as Citeseer, Citebase or Google Scholar. As institutional and subject-based repositories proliferate and Open Access mandates increase, more of the literature will become openly available in well managed data islands containing a much greater amount of detailed bibliometric metadata in formats such as RDF. Through the use of efficient extraction and inference techniques, complex relations between data items can be established. In this paper we explain the importance of the co-relation in enabling new techniques to rate the impact of a paper or author within a large corpus of publications

From the Desktop to the Cloud: Leveraging Hybrid Storage Architectures in Your Repository

4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PresentationsDate: 2009-05-19 01:00 PM – 02:30 PMRepositories collect and manage data holdings using a storage device. Mainly this has been a local file system, but recently attempts have been made at using open storage products and cloud storage solutions, such as Sun's Honeycomb and Amazon S3 respectively. Each of these solutions has their own pros and cons but There are advantages in adopting a hybrid model for repository storage, combining the relative strengths of each one in a policy-determined model. In this paper we present an implementation of a repository storage layer which can dynamically handle and manage a hybrid storage systemJoint Information Systems Committee (JISC

Video and Mass Storage

There are a number of challenges in handling large amounts of data for multimedia content - the sheer size of raw HD video data and the many versions of a video that are created during production and dissemination requires a bespoke infrastructure that is different in nature to the normal browser-based solutions. This session looks at the vidEPrints customisation designed to integrate with an institution's video production environment and handle dissemination via multiple services including YouTube and iTunes U
