ES-Rank: evolution strategy learning to rank approach (2017)
Conference Proceeding

Learning to Rank (LTR) is one of the current problems in Information Retrieval (IR) that attracts the attention from researchers. The LTR problem is mainly about ranking the retrieved documents for users in search engines, question answering and prod... Read More about ES-Rank: evolution strategy learning to rank approach.

Detecting collusive spamming activities in community question answering (2017)
Conference Proceeding

Community Question Answering (CQA) portals provide rich sources of information on a variety of topics. However, the authenticity and quality of questions and answers (Q&As) has proven hard to control. In a troubling direction, the widespread growth o...

Failing faster: overlapping patterns for property-based testing (2017)
Conference Proceeding

In property-based testing, a key problem is generating input data that satisfies the precondition of a property. One approach is to attempt to do so automatically, from the definition of the precondition itself. This idea has been realised using the...

High-frequency modulated secondary-side self-powered isolated gate driver for full range PWM operation of SiC power MOSFETs (2017)
Conference Proceeding

The present work proposes a solution for an isolated gate driver suitable for SiC MOSFETs. The driver is implemented by means of two small magnetic transformers, to provide the turn-on and turn-off gate signals, as well as the power required for an a...

Navigation by GPS-based systems: engagement with/disengagement from the place and the respective role of urban design (2017)
Conference Proceeding

The physical environment has started to be taken into consideration in mobile human– computer interaction more and more in order to bring humans and computers closer together. These studies focus on merging the aspects of actual situations in real wo...

Stimulating Conversation: Engaging Drivers in Natural Language Interactions with an Autonomous Digital Driving Assistant to Counteract Passive Task-Related Fatigue (2017)
Conference Proceeding

Engaging in conversation has been shown to be an effective countermeasure to passive task-related fatigue. To investigate the effectiveness of a digital assistant to fulfil the role of conversational partner in counteracting driver fatigue, twenty pa...

Exploring the Behaviour of Distracted Drivers during Different Levels of Automation in Driving (2017)
Conference Proceeding

Increased levels of automation in driving can reduce drivers’ situation-awareness and cause erratic changes to workload and skills degradation following prolonged exposure. In addition, drivers (particularly those who are vulnerable to the onset of b... Read More about Exploring the Behaviour of Distracted Drivers during Different Levels of Automation in Driving.

A predictive model of the visual demand associated with in-vehicle touchscreens (2017)
Conference Proceeding

Touchscreen-HMIs are increasingly popular within vehicles. Understanding the likely visual demand of new designs is therefore important but typically requires time-consuming and costly testing with functioning prototypes. Theoretical modelling allows...

Interactions with Projected Augmented Relief Models (PARM) (2017)
Conference Proceeding

Techniques for enhancing physical landscape models with dynamic maps and imagery, termed Projected Augmented Relief Models (PARM), are part of a revival of interest in the power of relief models as tools for geographic visualization. This method enab... Read More about Interactions with Projected Augmented Relief Models (PARM).

Partiality, Revisited: The Partiality Monad as a Quotient Inductive-Inductive Type (2017)
Conference Proceeding

Capretta's delay monad can be used to model partial computations, but it has the ``wrong'' notion of built-in equality, strong bisimilarity. An alternative is to quotient the delay monad by the ``right''notion of equality, weak bisimilarity. However,...

Optical difference engine for defect inspection in highly-parallel manufacturing processes (2017)
Conference Proceeding

Traditional defect inspection for highly-parallel manufacturing processes requires the processing of large measurement datasets, which is often not fast enough for in-situ inspection of large areas with high resolution. This study develops an all-opt... Read More about Optical difference engine for defect inspection in highly-parallel manufacturing processes.

A metrology horror story: the additive surface (2017)
Conference Proceeding

Measuring mental workload in IIR user studies with fNIRS (2017)
Conference Proceeding

Gathering neuro-physiological data during user studies, and analysing the continuous data they produce, typically involves making a tradeoff between detail and practical utility. is paper describes our long-term work-in-progress towards developing...

The Tetris model of resolving information needs within the information seeking process (2017)
Conference Proceeding

Theoretical abstractions, of many different aspects of search, have played a crucial role in driving research into human information seeking and retrieval forward. From models of the Information Seeking Process, to how we perceive search systems, the... Read More about The Tetris model of resolving information needs within the information seeking process.

Robust datamining (2017)
Conference Proceeding

Our long-term research goal is to develop datamining methodologies that are robust to changes in data and uncertainty. By robust we mean solutions remain ‘optimal’ when things change or are easily repaired. Broadly, this robustness can be achieved in... Read More about Robust datamining.

Interconnected alchemy: an apparatus for alchemical algorithms (2017)
Conference Proceeding

The trope of the fraudulent or occult alchemist, prevalent since the mediaeval period of alchemy’s introduction into European thought, belies the endeavour of practitioners from ancient Egypt onwards. Alchemists used observation, experimentation, and... Read More about Interconnected alchemy: an apparatus for alchemical algorithms.

Talking with conversational agents in collaborative action (2017)
Conference Proceeding

This one-day workshop intends to bring together both academics and industry practitioners to explore collaborative challenges in speech interaction. Recent improvements in speech recognition and computing power has led to conversational interfaces be... Read More about Talking with conversational agents in collaborative action.

"Do animals have accents?": Talking with agents in multi-party conversation (2017)
Conference Proceeding

In this paper we unpack the use of conversational agents, or so-called intelligent personal assistants (IPAs), in multi- party conversation amongst a group of friends while they are socialising in a café. IPAs such as Siri or Google Now can be found... Read More about "Do animals have accents?": Talking with agents in multi-party conversation.

"It's not yet a gift": Understanding digital gifting (2017)
Conference Proceeding

A myriad of digital artifacts are routinely exchanged online. While previous studies suggest that these are sometimes considered to be gifts, CSCW has largely overlooked explicit digital gifting where people deliberately choose to give digital media...
