IEEE talks: JEEVES and the Speculative W@nderverse
In October 2015 we attended two IEEE conferences in the USA. Daniel Rough presented a full paper at the IEEE Symposium on Visual Languages and Human-Centric Computing, October 18–22, in Atlanta, Georgia. Uta Hinrichs presented a full paper at the IEEE Information Visualization (InfoVis) conference as part of VizWeek, October 25-30 in Chicago, Illinois. You can find details of these and all our papers on the publications page.
On November 10th, Daniel and Uta will reprise their talks here in St Andrews and everyone is welcome to attend. You can find the details for the two talks below along with links to the papers via the University of St Andrews research portal.
Talk 1 by Daniel Rough
Title: Jeeves – A Visual Programming Environment for Mobile Experience Sampling
Authors: Rough, D and Quigley, A.
Abstract: The Experience Sampling Method (ESM) captures participants’ thoughts and feelings in their everyday environments. Mobile and wearable technologies afford us opportunities to reach people using ESM in varying contexts. However, a lack of programming knowledge often hinders researchers in creating ESM applications. In practice, they rely on specialised tools for app creation. Our initial review of these tools indicates that most are expensive commercial services, and none utilise the full potential of sensors for creating context-aware applications.
We present “Jeeves”, a visual language to facilitate ESM application creation. Inspired by successful visual languages in literature, our block-based notation enables researchers to visually construct ESM study specifications. We demonstrate its applicability by replicating existing ESM studies found in medical and psychology literature. Our preliminary study with 20 participants demonstrates that both non-programmers and programmers are able to successfully utilise Jeeves. We discuss future work in extending Jeeves with alternative mobile technologies.

Title: Speculative Practices: Utilizing InfoVis to Explore Untapped Literary Collections
Authors:

Hinrichs, U., Forlini, S. ; Moynihan, B.
Abstract:
In this paper we exemplify how information visualization supports speculative thinking, hypotheses testing, and preliminary interpretation processes as part of literary research. While InfoVis has become a buzz topic in the digital humanities, skepticism remains about how effectively it integrates into and expands on traditional humanities research approaches. From an InfoVis perspective, we lack case studies that show the specific design challenges that make literary studies and humanities research at large a unique application area for information visualization. We examine these questions through our case study of the Speculative W@nderverse, a visualization tool that was designed to enable the analysis and exploration of an untapped literary collection consisting of thousands of science fiction short stories. We present the results of two empirical studies that involved general-interest readers and literary scholars who used the evolving visualization prototype as part of their research for over a year. Our findings suggest a design space for visualizing literary collections that is defined by (1) their academic and public relevance, (2) the tension between qualitative vs. quantitative methods of interpretation, (3) result- vs. process-driven approaches to InfoVis, and (4) the unique material and visual qualities of cultural collections. Through the Speculative W@nderverse we demonstrate how visualization can bridge these sometimes contradictory perspectives by cultivating curiosity and providing entry points into literary collections while, at the same time, supporting multiple aspects of humanities research processes.

Distinguished Lecture: ‘Scalability and Fault-tolerance, are they the same?’ by Joe Armstrong
The first of this academic year’s distinguished lectures will be given by Professor Joe Armstrong, co-inventor of Erlang, on Monday 16th November 2015 at The Byre Theatre.
Abstract:
To build a scalable system the important thing is to make small isolated independent units. To scale up we just add more units. To build a fault-tolerant system the important thing to do is make small isolated independent units…. Does that sound familiar? Haven’t I seen that somewhere before? Oh yes, in the first paragraph! So maybe scalability and fault tolerance are really different names for the same thing.
This property of systems, namely that fault-tolerant systems were also scalable, was noticed years ago, notably in the design of the Tandem computer system. The Tandem was design for fault tolerance but rapidly became a leading supplier of scalable computer platforms. Thus it was with Erlang.
Erlang followed a lot of the Tandem design, it was built for fault-tolerance but some of the most successful applications (such as WhatsApp) use it for its scalability.
In this lecture I’ll talk about the intimate relationship between scalability and fault-tolerance and why they are architecturally the same thing.
I’ll talk about the design of Erlang and why scalable systems have to be built on non-shared memory abstractions.
Bio:
Joe Armstrong has been programming since 1967. He invented the programming language Erlang. He has worked as a programmer, founded a few successful companies and written a few books.

Lockheed Martin Award
Congratulations to our recent graduate Sam Elliott, who has won the Lockheed Martin Award 
for Best Engineered Project at the Young Software Engineer awards.
The Young Software Engineer of the Year Awards are given for the best undergraduate software projects drawn from across all students studying computer science and software engineering in Scotland.
Sam’s project, “A Concurrency System for Idris and Erlang”, takes an important step towards addressing the problem of writing large scale software, coordinated across several concurrently running machines, possibly distributed throughout the world. Writing such software is notoriously difficult because not only do programmers need to think about the progress of a an individual task, they also need to think about how data is communicated between each task.
The project combines Idris, a new programming language developed at the University of St Andrews, with Erlang, a programming language specifically designed for building robust distributed systems, and contributes a new system for running concurrent programs, with guaranteed behaviour, in a robust, industrial strength concurrent environment.

Seminar: ‘Measuring Personalization of Online Services’ by Alan Mislove
The School of Computer Science is delighted to welcome Alan Mislove from Northeastern University Boston to give his talk on ‘Measuring Personalization of Online Services
Abstract: Today, many web services personalize their content, including Netflix (movie recommendations), Amazon (product suggestions), and Yelp (business reviews). In many cases, personalization provides advantages for users: for example, when a user searches for an ambiguous query such as “router,” Amazon may be able to suggest the woodworking tool instead of the networking device. However, personalization is rarely transparent (or even labeled), and has the potential be used to the user’s disadvantage. For example, on e-commerce sites, personalization could be used to manipulate the set of products shown (price steering) or by customizing the prices of products (price discrimination). Unfortunately, today, we lack the tools and techniques necessary to be able to detect when personalization is occurring, as well as what inputs are used to perform personalization.
In this talk, I discuss my group’s recent work that aims to address this problem. First, we develop a methodology for accurately measuring when web services are personalizing their content. While conceptually simple, there are numerous details that our methodology must handle in order to accurately attribute differences in results to personalization (as opposed to other sources of noise). Second, we apply this methodology to two domains: Web search services (e.g., Google, Bing) and e-commerce sites (e.g., BestBuy.com, Expedia). We find evidence of personalization for real users on both Google search and nine of the popular e-commerce sites. Third, using fake accounts, we investigate the effect of user attributes and behaviors on personalization; we find that the choice of browser, logging in, and a user’s previously content can significantly affect the results presented.
Bio: Alan Mislove is an Associate Professor at the College of Computer and Information Science at Northeastern University. He received his Ph.D. from Rice University in 2009.

Seminar: ‘Designing trusted and engaging forms of peer to peer healthcare’ by Pam Briggs
The School of Computer Science are delighted to welcome Pam Briggs from Northumbria University, Newcastle who will deliver her talk on Trust and Engagement.
Abstract: Patients now generate a significant amount of online material about health. This raises questions about how we should design websites featuring patient knowledge and experience in order to ensure those sites provide a good match to patient needs. In this presentation I describe a structured participatory methodology for the development and evaluation of a set of patient experience websites that took place over three phases, consistent with experience based co-design:
(1) a capture phase in which we w
orked with patients to understand their reactions to existing websites; (2) an understand phase in which we translated this information into a patient-engagement framework and accompanying set of design guidelines and (3) an improve phase, where we used these guidelines to create three new health websites that were then assessed as patient experience interventions in a range of empirical studies.
Bio: Pam holds a Chair in Applied Psychology, delivering innovative research and consultancy around issues of identity, trust and security in new social media. Her research seeks answers to three main questions: Why and when do we feel secure in disclosing sensitive identity information about ourselves? What makes us trust an electronic message? How and when do we seek to protect our privacy?
In the last five years, Pam has published over forty articles on human perceptions of trust, privacy and security in computer-mediated communication and has recently developed, with colleagues, an innovative model of health advice-seeking online (ESRC funded). She has given a number of invited addresses on online trust and e-health, including an invited address on e-health to the World Health Summit 2009, the opening address at the Second International Conference on Privacy, Security and Trust (Canada) and the keynote to the 2010 IFIP Trust Management conference in Morioka, Japan. She has been a member of ESRC’s fellowship and CASE studentship committees and has recently made a contribution to the Govt. Office for Science’s Technology Foresight programme on the Future of Identity. She is currently a member of EPSRC’s new Identity Futures Network and also EPSRC’s Cybersecurity Network. She is one of the founder members of the UK’s new ‘Science of Cybersecurity’ Institute, funded by GCHQ in association with RCUK’s Global Uncertainty Programme.
