Big Data Analytics

Research Group, Computer Science, University of Hull

Welcome!


We are the Big Data Analytics research group (BDA) in the Department of Computer Science and Technology (CST) at the University of Hull. We collaborate with the Dependable Intelligent Systems (DEIS) research group in CST, and also work closely with other parts of the university, including the Viper HPC team, the Energy and Environment Institute, and the Aura Centre for Doctoral Training Centre in Offshore Wind Energy and the Environment.

We first came together as a group in 2017 and have since been growing an interdisciplinary research portfolio in artificial intelligence and data analytics, particularly focusing on research in (deep) machine learning, interactive systems and natural language processing, and increasingly AI for sustainability and environmental modelling. We have an increasing number of collaborations with partners in academia, industry and the public sector, generating novel fundamental research, knowledge transfer and impact acceleration projects.

Our Research

Deep Learning and Data Analytics

We apply machine learning, mostly deep learning, in all our research projects, due to its ability to learn features from large datasets and identify patterns in disparate, large and noisy datasets. Most of our work on natural language processing and other time-series applications uses LSTM/GRU or transformer models (e.g. for sentiment analysis, natural language generation) while other projects in image analysis and sensory output analysis have used CNNs or autoencoders.

Our research in this area focuses on deep learning models that are transparent and interpretable and can explain the rationales behind their actions - this is important in many commercial and real-life applications to increase trust, helps to avoid bias and discrimination in AI models, and makes them generally more accountable.

We are also interested in fast learning systems and investigate topics in transfer learning, divide-and-conquer approaches to learning and efficiency. See our deep learning publications for details.

Natural Language and Social Media

Natural language processing (NLP) refers to approaches that analyse, generate and process natural language automatically using computational techniques and algorithms, mostly based on machine learning. Our strengths lie in natural language generation, that is the automatic generation of language from non-linguistic data sources, such as data-to-text generation, (spoken) dialogue systems, i.e. systems that engage in conversations with users to solve problems or provide information, sentiment analysis in text and social media and text classification and analysis.

We are also interested in social media analysis, including projects on sentiment analysis and mental health based on linguistic profiling, flood forecasting and emergency situation assessment from social media and topics in digital conservation, such as public opinion mining and the monitoring of species. See our natural language processing publications for details.

Interactive Systems and Decision Support

Interactive systems can interact with their users in different ways, including text, speech, haptic or other multimodal input. A common distinction is between task-oriented interactive systems that target a particular domain, e.g. answering user queries on restaurant or tourist attractions in the local area, and open-domain systems who attempt to answer any question, e.g. using information retrieval methods from the web. Most personal assistant fall into the latter category. Finally, chatbots have no purpose of informing but rather aim to entertain users by engaging in casual chat.

Our group is interested in human-like behaviour of interactive systems, e.g. the incremental planning of utterances and the analysis of linguistic features in different conversational contexts. Most recently we have worked on interactive decision support systems for various real-life applications, most notably in the wind domain, where we use interaction as a way to provide easy and intuitive access to the inner workings of wind turbines to support operations and maintenance. See our interactive systems publications for details.

Sustainability and the Environment

We are applying AI and machine learning techniques to help solve problems in sustainability and environmental research. We are part of the EPSRC Aura CDT on Offshore Wind and the Environment, and we have a strong interest in the digitalisation of offshore wind. As part of this, we use AI to improve operations and maintenance of wind turbines to improve their reliability and usability as an alternative to fossil fuel-based energy sources. We achieve this through detailed and explainable fault forecasting and the automatic generation of maintenance strategies from expert knowledge sources.


Other research includes the forecasting of floods from high-frequency and social media data sources and the monitoring of water quality in the North Sea from sensory data and satellite images to achieve longer-term forecasting of the effects of human activity or environmental factors on water quality. We are currently growing our research on using AI towards the conservation of species. See our sustainability publications for details.

Dr Nina Dethlefs
, Senior Lecturer   
Natural language processing, interactive systems, artificial intelligence
    Full profile

    I am a Senior Lecturer in Computer Science at the University of Hull, Yorkshire, UK, where I lead the Big Data Analytics Research group. I am also currently Director of Research for Computer Science and Technology and Aura CDT Theme lead for "Big data, sensors and digitalisation for the offshore environment". Before coming to Hull, I was a Research Fellow in the The Interaction Lab at Heriot-Watt University, Edinburgh. I have a PhD in Computational Linguistics from the University of Bremen, Germany.

    My research interests lie at the intersection of machine learning and natural language processing (NLP), particularly in the areas of data-to-text and natural language generation (NLG), interactive systems, assistive technologies, domain transfer and adaptability for data analytics in a wider AI context. I have spent the last few years working with neural networks as a primary algorithm family but have previously worked with graphical models, clustering and reinforcement learning. Most recently I have become interested in applying AI and NLP in "useful" contexts such as mental health and the environment, particularly towards sustainability. I am interested in the digitalisation of the offshore wind industry to make wind turbines more reliable. I am also interested in the effects of human activity on water quality and the forecasting of natural events such as floods. When I have time I do some research in digital conservation using AI and text classification.

Onatkut Dagtekin
, PhD Student   
Artificial intelligence, machine learning, environmental modelling, natural language processing
    Full profile Onatkut is currently a PhD student in Computer Science at the University of Hull. He holds an MSc degree from the University of Manchester. For his PhD project, he investigates deep learning techniques to discover key predictors of water quality from high-frequency sensor outputs. These techniques aim to be as much as possible independent of particular geographical locations but rather rooted in the environmental context in which they occur. This can make them potentially transferable across different water bodies and regions of the world, including e.g. phenomena such as proximity of water to farmland, caves, industrial activity, impact of natural phenomena, such as land slides, floods, and other weather events. The overarching goal of the project is to be able to understand and predict the impact of human activity on aquatic ecosystems and wildlife.


Luana Mincarelli
, PhD student   
Marine biology
    Full profile

    The aim of my PhD project is to investigate how different combined stressors act in the environment, with particular attention to biological responses in mussels.

    I obtained an MSc in Marine Biology at Marche Polytechnic University (Ancona, Italy), working on a project concerning the modulatory effect of climate change (global warming and ocean acidification) and heavy metals exposure on biological responses of the Mediterranean mussel Mytilus galloprovincialis.

    The first part of my PhD involves the exposure of the blue mussel Mytilus edulis to several stress compounds. At the moment, I’m studying how different temperatures and phthalate exposure can affect biological responses of blue mussels. Finally, the second part of my project will involve data analysis: at the end of my PhD, I would like to have collected enough data to use artificial intelligence and machine learning for simulating future climate conditions and consequence for mussel populations.
