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.

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 wBriggs_Pamorked 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.

Toward Workflow Management for Experimental Science?

The School of Computer Science welcomes the opportunity to hear from Dr Babak Esfandiari from Carleton University, CBabak Esfandiarianada who will be delivering his talk on ‘Toward Workflow Management for Experimental Science?’.

Abstract: Data, code, and other digital scientific artifacts are often found (at least by this presenter) to be out-of-synch, unreliable, poorly organized and only partially available. This makes science often hard to reproduce. In this talk, I demo an online tool to manage the workflow of a scientific project, and I speculate over how or whether it can help address these issues.

Bio: Babak Esfandiari is an Associate Professor at Carleton University, a comprehensive university located in the capital of Canada, Ottawa, Ontario. He obtained his PhD from Montpellier II, which specializes in Science and Technologies. His research is in agent-based systems; network computing; object-oriented design and languages.

Seminar ‘TODAY’: Brand Objects and Gradual Contracts by Timothy Jones

The School of Computer Science welcomes Timothy Jones, a PhD student from Victoria University of Wellington,New ZealandTimothy Jones.

Abstract: Adding object branding to an existing structural system integrates nominal and structural typing without excessively complicating the type system. We have implemented brand objects to explicitly type objects, using existing features of the structurally typed language Grace, along with a static type checker which treats the brands as nominal types. We intend to extend this approach to arbitrary, gradually enforced contracts and investigate the language features necessary for their implementation.

Bio:

Grace

I am currently involved in the Grace programming language project, through the Hopper implementation of the language, as well as formalising the language’s semantics. You can find an online editor for Grace at grace/editor, and the Gribber music system (a Grace plugin for Gibber) at grace/gibber.

Haskell

I’m also an avid Haskeller. My most successful contribution is the http-media library, part of a larger attempt to simplify REST resources in the Snap web framework. I’ve tutored the Programming Languages (Haskell and Prolog) course at VUW for several years, as well as taught the Advanced Programming Languages course.

School Seminar: Efficient Privacy Preserving Data Mining via Secure Computation by Dr Changyu Dong

The School of Computer Science welcomes the opportunity to hear from Dr Changyu Dong, from the Department of Computer and Information Sciences University of Strathclyde, who will be delivering his talk on ‘Efficient Privacy Preserving Data Mining via Secure Computation’. Chanyu Dong

Abstract: Loosely speaking, secure computation allows parties to compute a function jointly while keeping their inputs private. Participants of secure computation learns only the output of the function, but nothing about the others’ private inputs. An oblivious application of secure computation is privacy preserving data mining. Imagine a scenario in which Amazon and Facebook want to find correlations between their users’ activities. With current technology, this cannot happen because none of the companies is willing to disclose its own data to the other. Secure computation can remove this barrier because data remains private during  and after the computation. In the past, secure computation is considered to be only theoretical because of its inefficiency. Recently much effort has been made to make secure computation practical. In this talk, I will present some recent advancements in this area. I will first introduce Private Set Intersection (PSI), an important secure computation primitive, and how it can be realised efficiently. I will show how PSI can be applied to linking record in databases (private record linkage) and finding association rules. I will then show how fully homomorphic encryption, an emerging cryptographic technology, can be used in building efficient secure computation protocols, and in turn be used for privacy preserving data mining.

Bio: Changyu Dong is a lecturer at the University of Strathclyde. He obtained his PhD from the Department of Computing at Imperial College London in 2009. His research is in cyber security, specifically in applied cryptography. Since 2006, He has published 27 research papers in major journals and international conferences, including the most prestigious venues in security such as ACM CCS, ESORICS and Journal of Computer Security. He has served on and chaired program committees for many conferences and workshops, and is a regular invited reviewer for top international journals including Journal of Computer Security, IEEE Transactions on Dependable and Secure Computing and IEEE Transactions on Information Forensics and Security. Shortly after moving to Strathclyde in 2011, he started his research on efficient secure computation. This research direction has led to some breakthroughs in secure computing for Private Set Intersection and Private Information Retrieval protocols, which he applied in domains such as data mining.

June 2nd, Seminar by John Stasko: “New Approaches for Information Visualization: Rethinking Existing Notions”

The School of Computer Science welcomes the opportunity to hear from Professor John Stasko of Georgia Tech,who will be delivering his talk on “New Approaches for Information Visualization: Rethinking Existing Notions” remotely. John Stasko

Abstract:
As the field of information visualization matures, researchers are able to reflect on, and perhaps even question,     some long-accepted notions from the area. In this talk, I focus on three such notions:
* Representing network data through force-directed node-link diagrams
* Focusing on visual representation first and foremost
* Evaluating visualizations through user studies and experiments
Although these ideas clearly have value as evidenced by their acceptance and longevity, I have begun to question      the wisdom of each. In this talk I’ll explain my concerns about these notions and I’ll suggest a new, alternative approach to each as well.       To support these arguments, I will describe a number of research projects from my lab that illustrate and exemplify the new approach.

Bio:
John received the B.S. degree in Mathematics at Bucknell University in Lewisburg, Pennsylvania (1983) and Sc.M. and Ph.D. degrees in Computer Science at Brown University in Providence, Rhode Island (1985 and 1989). He joined the faculty at Georgia Tech in 1989, and he is presently a Professor in the School of Interactive Computing in the College of Computing. His primary research area is human-computer interaction, with a focus on information visualization and visual analytics. John is a senior member of the ACM and IEEE. He was named an ACM Distinguished Scientist in 2011 and an IEEE Fellow in 2014. He also received the 2012 IEEE VGTC Visualization Technical Achievement Award. In 2013 John served as General Chair of the IEEE VIS conferences in Atlanta, and he was named an Honorary Professor in the School of Computer Science at the University of St. Andrews in Scotland.
