Alex Bain will be running the London Marathon this year, for wordwide cancer research and has been busy fundraising with a car wash, calendars and a Burns Night. He will be holding a bake sale on Friday 19th February in the school. Help support all his hard work in training for the event.
Abstract:
One of the limitations of semantic parsing approaches to open-domain question answering is the lexicosyntactic gap between natural language questions and knowledge base entries — there are many ways to ask a question, all with the same answer. In this paper we propose to bridge this gap by generating paraphrases to the input question with the goal that at least one of them will be correctly mapped to a correct knowledge-base query. We introduce a novel grammar model for paraphrase generation that does not require any sentence-aligned paraphrase corpus. Our key idea is to leverage the flexibility and scalability of latent-variable probabilistic context-free grammars to sample paraphrases. We do an extrinsic evaluation of our paraphrases by plugging them into a semantic parser for Freebase. Our evaluation experiments on WebQuestions benchmark dataset show that the performance of the semantic parser significantly improves over strong
baselines.

Shashi Narayan is a research associate at School of Informatics at the University of Edinburgh. He is currently working with Shay Cohen onthe problems of spectral methods for parsing and generation. Before,he earned his doctoral degree in 2014 from Université de Lorraine,under the supervision of Claire Gardent. He received Erasmus MundusMasters scholarship (2009-2011) in Language and CommunicationTechnology (EM-LCT). He did his major in Computer Science and Engineeringfrom Indian Institute of Technology (IIT), Kharagpur India. He is interested in the application of syntax and semantics to solvevarious NLP problems, in particular, natural language generation,parsing, sentence simplification, paraphrase generation and questionanswering.
Congratulations to Jakub Dostal, who successfully defended his thesis today. He is pictured below celebrating with supervisor Professor Aaron Quigley, internal examiner Dr Miguel Nacenta and external examiner Dr Keith Cheverst from the University of Lancaster.
The 2015 PhD Reading Party was held at the Burn, a Georgian Mansion at the foot of Glenesk in the North East of Scotland in December last year. It was an opportunity for research students to network, brainstorm and talk about their research and interests with colleagues in a relaxed atmosphere.
There were twenty-two (22) student talks, each of which lasted for up to 10 minutes including time for questions and discussions. Two members of staff – Ruth Letham and Ozgur Akgun – also gave talks, the former on teaching opportunities and career paths and the latter on reproducible research and research streams in academia. At the end of the talks, the staff members provided feedback and facilitated small group brainstorming sessions based on the interests and research themes that emerged.
It wasn’t all work and no play, as the gang explored the scenic landscape, wandered through the nearby woods and streams, and contemplated the complexities of the universe while star-gazing at night. Indoors, the gang played pool, table tennis, darts and cards, and participated in organised activities including a pub quiz (because there’s no such thing as too much trivia knowledge), presentation karaoke (because extemporising is fun and useful) and a host of board games (because why not?).

The School of Computer Science are delighted to welcome Dr Oana Andrei, from the University of Glasgow, to give her talk on Probabilistic Formal Analysis of App Usage to Inform Redesign.
Abstract: Good design of mobile apps is challenging because users are seldom homogeneous or predictable in the ways they navigate around and use the functionality presented to them. Recently we set out a process of app analysis intended to support understanding of use but also redesign using probabilistic model checking. In this talk I will show how to infer admixture models of activity patterns from various time cuts of app usage logs, characterise the activity patterns by probabilistic temporal logic properties using model checking, and compare the admixture models longitudinally and structurally. I will illustrate this work via a case study of a mobile app presenting analytic findings and discussing how they are feeding into redesign. We had posited that two activity patterns indicated two separable sets of users, each of which might benefit from a differently tailored app version, but our subsequent analysis detailed users’ interleaving of activity patterns over time – evidence speaking more in favour of redesign that supports each pattern in an integrated way. We uncover patterns consisting of brief glances at particular data and recommend them as possible candidates for new design work on widget extensions: small displays available while users use other apps.
Bio: Oana Andrei is a Research Fellow at the School of Computing Science, University of Glasgow. Her research interests involve fundamental aspects of theoretical computer science, mainly formal modelling and analysis of concurrent and stochastic systems. The applications I study concern mobile app analytics, vehicular networks, sensor systems, biochemical networks, and autonomic computing.
Abstract:
For many of us, interacting with data on mobile devices such as phones and tablets is commonplace in our lives, e.g. phone call data, TV guide, maps, fitness and wearable data. With the introduction of smart watches, the screen size of mobile devices has dramatically decreased. This reduction in screen real estate provides challenges for the design of interfaces, including the presentation and exploration of data visualisations. Using bar charts as an example, this presentation will explore the shortcomings of current zooming techniques on very small screens and consider proposed guidelines for the development of simple data exploration applications. Key design features such as the need for overview and context will be considered in respect to a simple and effective data exploration task.
