Understanding data analytics at BICOD

Lucy Tallentire from the School of Business, Economics and Informatics reports on the biennial British International Conference on Databases (BICOD).

Award of Best Research Student paper prize to Alexandru Bogatu, by Alastair Green of Neo Technology

From 10-12 July, Birkbeck’s Department of Computer Science and Information Systems played host to a wealth of insightful research discussion at the biennial British International Conference on Databases (BICOD). Birkbeck has a long-standing association with BICOD since its inception in the 1980s, with three generations of Computer Science researchers at Birkbeck having contributed to its legacy.

In her opening address, Professor Alex Poulovassilis, Deputy Dean of Birkbeck’s School of Business, Economics & Informatics, and General Chair of this year’s BICOD, highlighted Birkbeck’s long-standing contributions to the conference. She gave special thanks to this year’s Keynote speakers and those delegates who had travelled from abroad for the occasion. The last time Birkbeck hosted the conference in 1997 it was still known as the British National Conference on Databases (BNCOD) but this name was changed in 2015 to reflect the aim of the conference to be a platform for research discussion both nationally and internationally: “The geographical and thematic scope of this year’s papers and the interest from all over the world serves to demonstrate the conference’s continuing success.”

The theme of this year’s BICOD was Data Analytics, and the programme kicked off with a Keynote talk from Dr Tim Furche, Lecturer in Computer Science at the University of Oxford and Co-Founder of Wrapidity Ltd. Tim stressed the importance of translating research in AI and Machine Learning into practically applicable technology – in the case of his company, in the large-scale extraction of useful data from websites.

Short presentations by the four students vying for the best PhD paper prize followed. The judges commended the quality of the competition and praised the investigation and presentation of all the students. The winner, Alex Bogatu, collected his prize from the sponsor Neo Technology.

Further conference sessions over the course of the event comprised of two more Keynotes, from Professor Elena Baralis and Dr Sihem Amer-Yahia; two Tutorials, from Professor Leopoldo Bertossi and Dr Vasiliki Kalavri; and further research paper presentations, with subjects ranging from Data Exploration, Multidimensional Data and Graph Data Querying.

Keynote Speaker Professor Elena Baralis

On the final morning of the conference, there was also a unique chance to enjoy a joint session between BICOD and the International Joint Conference on Rules and Reasoning (RuleML + RR), which followed the BICOD conference at Birkbeck. The leading international joint conference in the field of rule-based reasoning, RuleML + RR brought a number of new delegate perspectives to the audience, as well as a focus on theoretical advances, novel technologies and innovative applications for rules and reasoning.

The BiCOD team would like to thank the conference sponsors for their generous support: Neo Technology, ONS, Palgrave Macmillan and The Information Lab.

Applying Big Data to Economics

Lucy Tallentire from the School of Business, Economics and Informatics at Birkbeck and CSIS PhD candidate Seongil Han report on a recent conference at the Birkbeck Centre for Data Analytics (BIDA).bidaWhat can we learn from Big Data, and how can Big Data analytics be applied to the field of Economics? These were just some of the questions answered by a one-day conference held by Birkbeck Institute for Data Analytics (BIDA) on Monday 5 June. The event was organised in collaboration with the Department of Economics, Mathematics and Statistics, to bring together researchers from statistics, applied mathematics, computer science, finance and economics to enhance the research environment and promote cross-disciplinary collaboration within the College, and with a wider external audience.

Birkbeck’s Professor Stephen Wright kicked off proceedings with an insightful presentation on the application of Big Data to large-scale surveys and maps. In his research project of residential land supply in 27 EU countries, he examines sources such as Google Maps, ONS/Ordnance Survey and Open Street maps to explain large differences across EU countries and identify whether there are restrictions on residential land. Professor Wright concluded that a large proportion of the regional variation in supply of residential land in the EU can be explained econometrically and is very strongly determined by regional geography and history.

Guest speaker Giovanni Mastrobuoni, Professor of Economics in Department of Economics, University of Essex, provided a unique insight into the role of Big Data analytics on police patrols and crime. Based on recent evidence that police deployment reduces crime, the project was designed to identify whether the elasticity of crime with regard to policing remains the same, and whether it is worth randomly increasing mobile police presence in an area. The results suggest, however, that big data is only useful with good prior identification; elasticity is negligible if identification is low, and random mobile patrolling cannot reduce crime significantly.

The second part of the conference focused on big data in business, economy and strategy. Professor Roger Maull, from the Department of Digital Economy in University of Surrey, discussed business models in relation to the digital economy, introducing 3 new approaches to the economy for big data – digitisation, datafication and digitalisation. He explained business models with industry dynamics and emphasised the following qualities:

  • value proposition, or what the customer pays for;
  • value creation, or how one delivers what the customer pays for;
  • value capture, or how the customer pays for it.

Big data has allowed significant advancements in personalisation and customisation, which also link to HAT (Hub of All Things): an IT business services to store and customise the personal data, as a real business model for personal data.

Final speaker Ernesto Damiani, from the Etisalat British Telecom Innovation Centre, Abu Dhabi, introduced the prospect of big data analytics as a service. He started by highlighting the 5 Vs of big data:

  • Variety in analytics model: static ways vs dynamic ways;
  • Volume;
  • Velocity;
  • Value;

He also compared traditional analytics with big data analytics and explained a change in paradigm for data analytics, which is supported by the example of Google.

The conference succeeded in providing a comprehensive introduction to the many ways in which big data analytics, such as text mining techniques, can be applied to Economics and business. Big data analytics continue to attract a great deal of attention in academia and industry, with an increasing amount of unstructured data available on web; it is vital to apply big data analytics to various problems to supplement qualitative information to conventional descriptive analytics and infer the predictive analytics.

BIDA would like to thank the presenters and all those who attended for their insightful comments and discussion. You can find out more about the Birkbeck Institute for Data Analytics on their website.
