Seminar this week - System-mediated & User-mediated Collaborative Information Seeking (CIS)

Chirag Shah from University of North Carolina (UNC) at Chapel Hill presented a talk entitled.

System-mediated and User-mediated Collaborative Information Seeking (CIS)

Abstract:

Information seeking is typically seen as a single person activity, done in isolation without the support of other people. It is time we revise this assumption and acknowledge that seeking and using information can be a social activity, done in collaboration with others. Many situations call for such collaboration while seeking information. For instance, a couple planning a vacation have the same information need, but may have different expertise and opinions about how, where, and what aspects of the trip. In most such situations, we end up using different tools, such as browser, messenger, email, etc., in ad hoc manner to accomplish the common goal. Integrated solutions that not only provide the support for such activities seamlessly, but also encourage and facilitate collaborations in impromptu fashion are highly desired. In this talk I will present two different views of doing this - system-mediated collaboration, and user-mediated collaboration. The former can be facilitated using different algorithms working in the back-end, and the latter can be achieved by providing interface level support where the users can decide how they want to divide the task and share the information.

Charag is a doctoral candidate at School of Information & Library Science (SILS) at University of North Carolina (UNC) at Chapel Hill. He received his MS in Computer Science from UMass Amherst, where he worked with Bruce Croft and James Allan on high accuracy retrieval, and topic detection and tracking. At UNC, he has been working with Gary Marchionini and Diane Kelly on various issues concerning exploratory information seeking and interactive information retrieval. He has also worked at many world-renowned research laboratories, such as FXPAL in California and National Institute of Informatics in Tokyo, Japan. His dissertation is focused on collaborative information seeking. He is also interested in social search and question-answering, digital preservation, and contextual information extraction. He has developed several tools for exploratory information seeking and extraction, including "Coagmento" for collaborative information seeking, and "ContextMiner" for capturing contextual information from multiple online sources.

Joint PhD presentation between Sheffield and Makerere, Uganda, delivered by Liliana Sepulveda Garcia

Last week saw the first presentation in a series of joint talks between the Information School's Health Informatics and Information Systems Research Groups in Sheffield. and Makerere University in Kampala, Uganda.The talks aim to promote research collaboration and knowledge sharing.

Dr Laura Sbaffi and Dr Efpraxia Zamani are organising this series and chairing the Sheffield presentations, and Prof Josephine Nabukenya will be chairing the presentations from Makerere.

In this first session, PhD student Liliana Sepulveda offered the audience a great overview of her PhD research on "An experiential study of the human-technology relationship between informal caregivers of people with dementia and assistive technologies".


There will be similar virtual meetings every month and the next schedule one is for Tuesday 11th June, when a PhD student from Makerere will be presenting their work. More details will be forthcoming.

New Article: Services for Student Well-Being in Academic Libraries: Three Challenges

Services for Student Well-Being in Academic Libraries: Three Challenges
Our Director of Research and Senior Lecturer, Dr Andrew Cox, has published a new article alongside Dr Liz Brewster at Lancaster University.

There has been a wave of interest in UK academic libraries in developing services to support student well-being. This paper identifies three fundamental and interrelated issues that need to be addressed to make such initiatives effective and sustainable. Firstly, well-being has to be defined and the impacts of
interventions must be measured in appropriate ways. Secondly, there is a need to identify the true nature of the underlying social problem around well-being. Thirdly, relevant approaches to the issue need to be located within the professional knowledge base of librarianship.

PhD student Gianmarco Ghiandoni presents at UK-QSAR conference

Gianmarco Ghiandoni, PhD student in our Chemoinformatics research group, recently attended and presented at the UK-QSAR conference in Cambridge.

Gianmarco attended the conference and presented a part of his PhD project, which involves the development of "Reaction Class Recommender Systems in de novo Drug Design".

'These algorithms are machine learning models that have recently acquired great importance due to their effectiveness in product recommendation', Gianmarco said. 'In particular, companies such as Amazon, Netflix, Spotify, etc., have built their reputations and businesses on the top of these models. At Sheffield, we have decided to apply these methods in order to produce suggestions for decision making in automated molecular design. The results from their application indicate that recommender systems can improve the synthetic accessibility of the designed molecules whilst reducing the computational requirements.'
