DSRS initiates collaborations with Taipei Medical University (TMU), Taiwan

We are thrilled to announce new international R&D collaborations between DSRS Lab and the International Centre for Health Information Technologies in Taipei Medical University (TMU), one of the highest-ranked higher education and global research institutions in Taiwan.

Taipei Medical University

This collaboration, due to start on early 2021, will count on the participation of experts from various disciplines related to Health, Medicine and Information Technology, with a focus on developing innovative AI-based digital health solutions guided by personalisation and user engagement to promote healthier lifestyles among specific sectors of the population.

This goes in line with -and follows up from- one of the lab’s key research lines on AI-guided RecSys for health & wellbeing lifestyle promotion, started back in 2018 under a 2-year Turing Fellowship with the UK’s Alan Turing Institute: a more necessary real-world problem than ever before at global scale, as evidenced by the consequences of the current world pandemic caused by (infamous) covid-19, as well as the global blueprint Agenda 2030 for Sustainable Development Goals (about which we also talk in this other post!)

More details to follow soon.

AI & Emerging Technologies for Sustainable Development Goals

DSRS Lab and DaSCI Institute Researchers have been taking part in an ambitious Knowledge-Transfer R&D study entitle “Engineering facilitator in the Sustainable Development Goals (SDGs): AI and Emerging Digital Technologies”.

As we approach the finish line of this study taken place during March-December 2020, we are very pleased to release the project’s Website, where it is shown how Artificial Intelligence can enable achieving the 17 SDGs proposed by United Nations by year 2030. This interactive site – available in both English and Spanish – highlights the trends followed by AI and emerging technologies as a facilitator, driving-force, obstacle or threat to the different targets underlying SDGs of economic, social and environmental nature.

Likewise, we distil key recommendations to be followed by governments, institutions, R&D institutions, stakeholders and ultimately the general public towards reinforcing the catalyser and enabler role that these technologies can play towards sustainability at all levels. Since if you are reading this post you are probably interested in how large-scale Decision Support and Recommender Systems in particular can contribute their grain of sand in this huge endeavour, we’re pleased to announce the result of the study show a lot of potential by these paradigms in many of the SDGs (for instance, for health and wellbeing, socio-economic governance, sustainable tourism, equality and social welfare, to name a few).

Finally, please make sure to participate in the large-scale (Poll) study for the whole world population, which we are conducting to know what you think about our proposed Recommendations for Action Plans in this study. Your opinion is very valuable to us!

A Book resulting from this study, published with the Spanish Royal Academy of Engineering, and undertaken in close collaboration with Ferrovial, will be available soon!

Keep calm and move south: DSRS Lab joins DaSCI Institute in Granada, Spain!

Descubre la magia de la ciudad de Granada

Having very recently materialised the plans – sought long time ago – to move to my home place in Spain by joining the University of Granada, the DSRS Lab in Bristol will of course follow.

The lab is now becoming part of the Andalusian Institute of Data Science and Computational Intelligence (DaSCI), a multi-university institute based in southern Spain and led by Prof. Francisco Herrera. Personally, I couldn’t be happier about this positive step forward.

Although all these changes happened amid an unprecedented global health crisis worldwide, this doesn’t mean that both the Lab members and collaborators – both existing and new alike – and myself aren’t working hard on new projects and collaborations within the frame of this institute with international projection!

An important news is that The Current DSRS Lab Website will soon be migrated into a new address, which will be announced very soon, both here and in our Twitter account, as well as on my personal webpage (www.ivanpc.com)

I would like to thank sincerely those people in Bristol University and The Alan Turing Institute who did make it possible the foundation of this lab (back on summer 2018) with their valuable, unconditional support. Thanks to them, we are now starting a new chapter in the Lab’s life as part of a cornerstone research Institute, with the growth of our team and R&D projects in which we will be involved. We will substantially update this Website along the next days with some news on these new updates and projects!

Stay safe, and stay positive and happy 🙂

Large-Scale Decision Making Overview, published in Information Fusion

The research area of Large Group Decision Making (LGDM) has acquired growing importance in the last 5 to 6 six years, with many researchers around the globe developing models and solutions to support collective decisions at large scale.

A variant of this LGDM framework, called Large-Scale Decision Making is the subject of this article published in Information Fusion (Impact Factor: 10.716, ranked 3/134 by ISI-JCR in Computer Science: Artificial Intelligence), in which the DSRS Lab collaborated with scientists from University of Granada (Spain), Tianjin University (China) and Sichuan University (China).


The last decade witnessed tremendous developments in social media and e-democracy technologies. A funda- mental aspect in these paradigms is that the number of decision makers allowed to partake in a decision making event drastically increases. As a result Large Scale Decision Making (LSDM) has established itself as an emerging and rapidly developing research field, attracting comprehensive studies in the last decade. LSDM events are a complex class of decision making problems, in which multiple and highly diverse stakeholders are involved and the provided alternatives are assessed considering multiple criteria/attributes. Since some of the extant LSDM re- search was extended from group decision making scenarios, there is no established definition for a LSDM problem as of yet. We firstly propose a clear definition and characterization of LSDM events as a basis for characterizing this emerging family of decision frameworks. Secondly, a classification of LSDM literature is provided. Effectively solving an LSDM problem is usually a complex and challenging process, in which reaching a high consensus or accounting for the agreement or conflict relationships between participants becomes critical. Accordingly, we present a taxonomy and an overview of LSDM models, predicated on their key elements, i.e. the procedures and specific steps followed by the existing models: consensus measurement, subgroup clustering, behavior man- agement, and consensus building mechanisms. Finally, we provide a discussion in which we identify research challenges and propose future research directions under a triple perspective: key LSDM methodologies, AI and data fusion for LSDM, and innovative applications. The potential rise of AI-based LSDM is particularly highlighted in the discussion provided.

The article establishes a taxonomy around which existing LSDM literature is overviewed, based on the key elements/processes undertaken in LSDM models (e.g. consensus measurement and building, subgroup clustering, behavior management…) and the types of approaches adopted by different scholars for each of these key elements.

Furthermore, the article provides a comprehensive discussion on the challenges and future research directions in LSDM, with special emphasis on (i) the potential role of AI and Data Fusion/Data Science technologies to improve these decision support models, and (ii) Innovative Areas of Application of LSDM.

1st International ‘Alan Turing’ Conference on Decision Support and Recommender Systems (DSRS-Turing 2019)

1st International ‘Alan Turing’ Conference on Decision Support and Recommender Systems (DSRS-Turing 2019)


London, UK. 21-22 November 2019

Decision Making processes constantly occur in our daily lives, both at an individual, collective and large-scale societal level. Even for machines and AI systems, making autonomous and rational decisions has nowadays become part of their core duties. Decision making often occurs amid highly dynamic, uncertain and data-pervaded scenarios, thereby becoming increasingly complex. This conference based in the UK’s Alan Turing Institute brings together international researchers, industry professionals and domain experts to discuss latest trends and ongoing challenges in:

  • Human and AI-driven complex decision making, e.g. group and multi-criteria decision-making.
  • Role of Machine Learning and Data-Driven AI techniques in supporting decisions.
  • Recommender Systems as tools for personalised decision support.
  • Interdisciplinary applications of decision making, decision support and personalisation: management, health and wellbeing, smart cities and urban planning, sustainability, government, leisure and tourism, networking and recruitment, etc.

The event particularly aims at exploring the existing – or potential – interaction between various AI techniques and applications, and state-of-the-art decision support and recommendation approaches. Young researchers (PhD students, postdocs) are particularly encouraged to attend for an opportunity to network with – and receive advice from – leading experts in the field.
