Gregory Abowd to give Distinguished LectureTitle: Computing and Autism: How a real problem can drive research in a different field
Location: Room 312-313 Margam Building
Date and Time: Thursday November 29th 2012. 4pm
Since 2002, I have targeted much of my research to challenges relating to autism. While this started and is continually fueled by a very personal motivation, I have been struck by how many interesting computing problems have surfaced in the context of trying to solve a real problem relating to autism. In this talk, I will give an overview of a variety of problem-driven challenges I and my collaborators have addressed and how in many cases the problem has opened up a rich computing problem to explore.

Alan Dix to Give Research SemimarTitle: Treading out Technology: theory meets praxis during a thousand mile walk round Wales
Location: Robert Recorde Room
Date and Time: Monday November 19th 2012. 4pm
AbstractNext year I will be walking around Wales following the Wales Coast Path that opened this year and Offa's Dyke long distance path up the borders. This is partly a personal journey reconnecting with the country of my childhood, but also a technological journey investigating the IT needs of the walker and the local communities through which I pass. Some of this will be mundane technologically speaking, but hopefully transformative in practice. However, I also expect to be pushed to the limits cartographically and theoretically. In particular, aspects of Semantic Web and the odd Galois Connection will be essential parts of the need to synchronise data between heterogeneous sources and following disconnection.
Alan Dix is a Professor in the School of Computer Science, University of Birmingham, and Senior Researcher at Talis, Birmingham, and when not in Birmingham or travelling elsewhere, lives on Tiree, a small Hebridean island. He is the son of a carpenter, wears sandals and has long hair and a beard, but thereafter all pretensions to saintliness end. Alan's research interests are varied and eclectic, although mathematics was (and is!) his first love the majority of his work is focused around the area of human-computer interaction - what happens when people use technology and how to design technology for people. He is the author of one of the key international textbooks in the area as well as other books and over 350 academic papers. Much of his career has been in academia, but in addition he has spent time in agricultural engineering research, local government IT, submarine design and dot.comstart-ups. With a colleague at Lancaster University he invented technology to make LEDs individually controllable; this is being released commercially and is expected to transform cityscapes across the world.

It is an ideal place to design, create and test ICT solutions optimized for the African continent. Professor Marsden also edits the "Under Development" column in interactions magazine.
Ian Witten to Give Research SemimarTitle: Semantic document representation: do it with Wikification
Location: Callaghan Lecture Theature
Date and Time: Thursday June 28th 2012. 2pm
Wikipedia is a goldmine of information. Each article describes a single concept, and together they constitute a vast investment of manual effort and judgment. "Wikification" is the process of automatically augmenting a plain-text document with hyperlinks to Wikipedia articles. This involves associating phrases in the document with concepts, disambiguating them, and selecting the most pertinent. All three processes can be addressed by exploiting Wikipedia as a source of data. For the first, link anchor text illustrates how concepts are described in running text. For the second and third, Wikipedia provides millions of examples that can be used to prime machine-learned algorithms for disambiguation and selection respectively Wikification produces a semantic representation of any document in terms of concepts. We apply this to (a) select index terms for scientific documents, and (b) determine the similarity of two documents, in both cases outperforming humans in terms of agreement with human judgment. We also apply it to document clustering and classification algorithms, and to produce back of the book indexes, improving on the state of the art in each case. The Wikipedia Miner toolkit is open source and runs quickly (using Hadoop to parallelize where appropriate).

Jenny Preece to Give Research SemimarTitle: Motivating citizens to contribute biodiversity data to citizen science projects: Melding human and computational skills
Location: Wallace Lecture Theatre
Date and Time: Wednesday June 13th 2012. 2pm
Online citizen science projects engage volunteers in collecting, analyzing, and curating scientific data. Existing projects have demonstrated the value of involving volunteers to collect data, but few projects have reached the full potential of volunteers and scientists working together. Understanding the shared and unique motivations of these two groups can help designers establish the technical and social infrastructures needed to promote effective partnerships.
In this talk I will present findings from several studies in which we examined: user traffic in the Encylopedia of Life (eol.org); motivational factors affecting participation in ecological citizen science projects; the role of a game in checking the accuracy of curating biodiversity data, and a game for motivating contributions from the field.
We found that volunteers are motivated by a complex framework of factors that dynamically change throughout their cycle of work on scientific projects; this motivational framework is strongly affected by personal interests as well as external factors such as attribution and acknowledgment. Identifying the pivotal points of motivational shift and addressing them in the design of citizen-science systems will facilitate improved collaboration between scientists and volunteers.
