ABSTRACT This paper proposes a 'rough co-citation', which is a measure of relationship to expand co-citation networks so as to include new relevant documents. A rough co-citation relationship is a linkage between a pair of documents which are cited by two other documents in a similar citation context. The linkage strength of a rough co-citation relationship may be weaker than the original co-citation relationship, because a rough co-citation relationship is determined by citations in two separate documents. Rough co-citation linkages, however, may yield new relevant documents that are not identified by the original co-citation linkages. For example, the rough co-citation can identify relevant documents that are published after the citing document of the original co-citation becomes public. This study conducted IR experiments to evaluate the search performances of retrieval methods using the co-citation networks expanded by the rough co-citation relationships. Specifically, the random walk with restart, which is one of the latest graph search algorithms, is applied to the expanded and original co-citation networks. Scores of the normalized discounted cumulative gain (nDCG@K) are then compared. The results indicate that the search performance of the method using the expanded network outperforms a baseline method using the original network. [ABSTRACT FROM AUTHOR]

ABSTRACT Altmetrics is an emerging measure for academic impact and it is gaining in global importance. In this paper, we analyse the altmetric landscape of Singapore, a young nation with a fast growing international research sector. We aim to find out if the coverage of altmetrics across the different disciplines is increasing along with the fast increase in the amount of research publications in recent years. We also look into how altmetrics relate to traditional citation counts as a measure of research impact. From our results, we see that there is overall an 18% coverage of altmetrics of Singapore publications from 2009 to 2013. The number of publications with available altmetric data has also been increasing over the years for most disciplines. Correlation results between citation counts and altmetrics show medium to low correlations with distinct differences amongst the various disciplines. A high coverage of altmetrics however does not seem to lead to larger correlations with citation counts. Singapore thus remains an intriguing case study to watch in the coming years.

ABSTRACT This panel brings together experts in bibliometrics and information retrieval to discuss how each of these two important areas of information science can help to inform the research of the other. There is a growing body of literature that capitalizes on the synergies created by combining methodological approaches of each to solve research problems and practical issues related to how information is created, stored, organized, retrieved and used. The session will begin with an overview of the common threads that exist between IR and metrics, followed by a summary of findings from the BIR workshops and examples of research projects that combine aspects of each area to benefit IR or metrics research areas, including search results ranking, semantic indexing and visualization. The panel will conclude with an engaging discussion with the audience to identify future areas of research and collaboration. [ABSTRACT FROM AUTHOR]

ABSTRACT The past decade has seen tremendous progress in the field of preservation, particularly with respect to preservation of digital materials. To date, however, there has been only minimal research activity within North America on the preservation of intangible cultural heritage, and its relationship to the preservation of material expressions of culture. Given the importance of intangible heritage to the cultural and scholarly record, we believe that a more significant research program in this area would be of benefit to the scholarly community. This panel will focus on the nature of intangible heritage and the problems in preserving it in a digital age. [ABSTRACT FROM AUTHOR]

ABSTRACT As management of research data becomes increasingly important to scholars and academic institutions, academic libraries can play a major role by offering research data services (RDS). This poster presents the results of a survey of the Ligue des Bibliothèques Européennes de Recherche-Association of European Research Libraries (LIBER) academic member library directors to find out what types of RDS their libraries are currently offering and what services they plan to offer in the future. The survey found that while most of these libraries currently offer or are planning to offer at least some RDS, consultative or reference-type services are offered more often than are technical or hands-on services. Most of these libraries are in discussions regarding data policies, collaborate with other organizations within or outside their own institutions to offer RDS, and most provide support for RDS skills development for staff members. This poster discusses the implications of these findings and offers directions for future research. [ABSTRACT FROM AUTHOR]

There are many indicators about the worldwide rise of agerelated neurodegenerative diseases, especially Alzheimer's Disease (AD). Significant and urgent improvements are needed in the areas of prevention, drug discovery, treatment, cost-effective delivery of health-care service, and caregiver support. Researchers and professionals from medicine, nursing, health care, computer science, economics and other disciplines have intensified interdisciplinary efforts to address this looming global crisis. To-date, Information Science has been peripheral to these collaborative developments, contributing primarily in traditional areas of user information needs and services. The presenters in this interactive panel will challenge participants with a simple but provocative question: "How can Information Science (IS) contribute to research on AD?" To inspire the generation of ideas for connections among existing streams in IS research and questions critical to AD, the panelists will describe briefly their own research in AD or related areas, and speak to their potential to advance research in AD. The audience will then engage in small group discussions for rapid idea generation, exchange and exploration. The discussions will be structured around interdisciplinary research areas developed at the University of Pennsylvania's Ware Alzheimer Program Model: 1. Drug Discovery, 2. Biomarkers, 3. Recruitment, Retention and Outcomes, 4. Care Coordination. The objective is to discuss: the potential for Information Science to contribute in the areas of research identified in the Model; unique perspectives (methods, theoretical frameworks, service models) that IS could provide; and potential research partnerships that could be established within and outside of IS. The session will conclude with a collective development of priorities for Information Science engagement in AD research. The participants will be encouraged to become instigators of an IS focus on AD research in their own disciplinary areas, and to contribute to the development of a collaborative virtual space for continuing discussion of these priorities.
