Usability Challenges for e-Science Rob Procter National Centre for e-Social Science & UTF rob.procter@ncess.ac.uk www.ncess.ac.uk 26-27 January, 2006 Usability Workshop, NeSC The e-Science Vision A globally connected, scholarly community promoting the highest quality scientific research. “e-Science is about global collaboration in key areas of science and the next generation of infrastructure that will enable it.” John Taylor, Director General of Research Councils, UK Office of Science and Technology “The goal of cyberinfrastructure is to provide an integrated, high-end system of computing, data facilities, connectivity, software, services, and instruments that enables all scientists, engineers and educators to work in new ways on advanced research problems that would not otherwise be solvable.” Peter Freeman, Director, CISE, NSF 2 Realising the Vision Now that early adopters are all on board and focus shifts from concept demonstrators to generic tools supporting real users, and users’ experiences of pilot projects is absorbed, important challenges for usability research are beginning to emerge. We can no longer assume that “if we build it, they will come.” 3 Individual and Group Usability Design usable research environments: – Simple but powerful user interfaces providing integrated access to tools, services and data. Support collaboration: – Local and distributed, small and large scale, in real-time and over time. Support evolution of research methods and tools: – Track and respond to change, provide training. 5 Organisational Usability Help build manageable infrastructures: – Easily configurable solutions. Provide dependable authorisation, authentication and access control mechanisms: – Simple to apply and to police. Support research governance: – Negotiating, representing and administering policies. 6 Community Usability Create incentives for sharing data: Develop sustainable models of technology supply: – Recognise and reward different forms of contribution. – Open source or proprietary? Support development of community knowledge repositories: – Standards for metadata and ontologies Respond to research drivers: – Demand for evidence-based research. 7 Work: The ‘Missing What’ in e-Science? Tendency to assume that there is only one kind of knowledge, only one kind of science and one scientific method. Knorr-Cetina (1999) has shown that scientific cultures are very diverse. She illustrates this by two detailed studies: high energy physics and molecular biology: – HEP has a history of large scale, trans-national collaboration because the science demands hugely expensive infrastructure which is only affordable if shared. This ‘collectivity of instruments’ is matched by a collectivity of physicists who collaborate in the design and running of experiments, and share the data. – Molecular biology is an individually oriented lab-bench science conducted in small laboratories, highly competitive and fragmented. Molecular biology’s ‘tools of the trade’, once big and expensive, became small, cheap and widely dispersed. HGP was molecular biology’s first attempt at ‘big science’, involving contributions from more than 350 laboratories. Impact of digital artefacts on scientific practice: – Astronomy’s reconfiguration from an observational field science to an image processing lab science. Are we witnessing a paradigm shift in molecular biology to a ‘theoretical’ science that manipulates masses of sequence data rather than biological samples and reagents; in silico experiments rather than wet science? 8 Challenge: Global Collaboration e-Science seeks to foster and enhance awareness ofcommunities. globally distributed research colleagues’ ‘presence’ Key questions include: Devising mechanisms toolsrealtotime support virtual meetings and mapping Compendium formation of dynamic, distributed research discussions/group sensemaking communities. recovering information Investigating and understanding from meetings enacting decisions/ requirements for collaboratories, coordinating activities organizational entities that span distance, Replay synthesising artifacts interaction support rich and recurring oriented to a common research area, and provide access to data sources, artifacts and tools. 10 Challenge: Trust e-Science raises significant concerns about trust in technologies, trust in data and trust between collaborators. Key research questions include: Understanding what makes technologies trustable and how to provide ‘trust affordances’ in e-infrastructure. Understanding how distributed communities impact formation of ‘cultures of trust’ and how to develop practices to deal with this. 11 Trust and Mobile Data Work of manipulating physical artefacts such as paper records affords natural, locally visible account of itself. Introducing digital artefacts can change visibility and accountability of work practices with implications for: – Trust in processes of data collection. – Trust in colleagues as interpreters of data. When data becomes mobile, can provenance information substitute for ordinary, everyday practices by which trust is achieved in co-located work settings? 12 Challenge: Representations for VOs Can Virtual Organisations (evolving ensembles of collaborating organisations and agreements) be made visible for members? Can users gain a sense of the implicativeness of their actions? How can contributors of data be assured that data is used in a prescribed fashion? Codifying of policies and auditing of interactions provides an opportunity to visualise VOs. S. Carlson, Uni. of Essex 14 Challenge: Representing Knowledge Production of new forms of knowledge is a central feature of the e-Science vision. Key research questions include: Investigating new forms of reasoning and their impact on requirements for tools. Understanding use of representations, how representations mediate research and how emerging forms are used in practice. Identifying new forms representations, including migration of existing techniques for visualisation to new communities. 16 Why don’t biologists modularise OWL ontologies properly? public-semweb-lifesci@w3.org “I don't blame them [MGED/PSI community] because to truly comprehend RDF/OWL is not an easy task, it takes not just the understand of technology itself but more so the vision on how things should and can work in SW.” “One thing we have to remember is that biologists are building ontologies to do a job of work. They are not produced as some end of CS or SW research” “Principles are all well and good, but we should know from decades of software engineering that saying "do it properly" isn't a solution. We need tooling and methodologies that do not in themselves hinder a domain specialist. In many cases it is easier to re-develop than re-use or even cut-and-paste from an existing ontology than it is to muck around “doing it properly”” “There is a gap between the view of ontology for CS people and for biological people. The ontology in biologists’ eyes are more of a treaty than logical representation, CS has the the reverse of that view. It needs dialog to bring the view to a middle ground and mechanisms to stretch to both directions.”17 C. Goble, Uni of Manchester Challenge: Methodologies A significant set challenges are centered on methodologies for designing and building e-infrastructure and tools. Building on efforts of early adopters: – Processes for turning bespoke prototypes into generically usable tools. Devising new methods for requirements capture, including requirements for work practices that are only as yet imagined: – Scalability of approaches which emphasize detailed investigation. – User involvement in design and development processes. – Co-realising tools through situated design and development. “We know of no scalable methods of requirements analysis that document the needs of vastly different user populations, continue to document changing needs over decades, coordinate investigation at multiple sites of use, design for large distributed entities, and absorb transformative changes in practice.” (Zimmerman and Nardi, 2006) 18 What is NCeSS is Doing? Entangled data project (Essex): – Case studies of three networks of researchers: • Distributed group of physicists. • Distributed users of a complex sociological dataset. • An ethnographic archiving project. Oxford e-Social Science (OeSS) - Ethical, Legal and Institutional Dynamics of Grid Enabled-Science: – Focusing on the social, institutional, ethical and legal issues surrounding e-Science infrastructures and research practices. Many NCeSS projects have made usability an explicit goal. 19 MiMeG Mimio receiver Tools to analyse audio-visual qualitative data and related materials collaboratively over the Grid. Co-located researchers are able to see analyst prepare to produce a stroke in front of the screen, researchers at remote sites are only aware of the stroke at the time it is being produced. Plan to start conveying where annotating devices are with respect to display, through tracking pens’ positions around intervening space along with appropriate remote visualisation.

Calls for multidisciplinary efforts conducted on an unprecedented scale, involving users, usability researchers and developers. Must be coordinated and must look to plan beyond immediate funding opportunities. Should exploit collaboration technologies now available. Above all, usability must be strongly embedded in the e-Science programme. If it is not, how can we change that? CHI workshop, Montreal, April 22nd, 2006 23
