Here is a list of projects where DSRS members are taking part – or have taken part – since the establishment of the group on 2018. We have initiated our activities as a group very recently, so please do not expect a long list of projects just yet 🙂
Projects listed in this page include international collaborations, partnership building initiatives, interdisciplinary research, etc.
Alan Turing Fellowship: Promoting Healthy Living Habits via Recommender Systems
DSRS members and role: Ivan Palomares Carrascosa (Turing Fellow), Ercan Ezin, James Neve, Hugo Alcaraz-Herrera (project collaborators).
Project partners: Jean Golding Institute (University of Bristol)
Start Date: 1st November 2018
Intelligent Decision-Making and Big Data Fusion Strategies in Recommender Systems: application to Point-of-Interest and Leisure Recommendation in Smartcities
DSRS members and role: Iván Palomares Carrascosa (Principal Investigator)
Type of project and funding body: International Strategic Fund (University of Bristol)
Multi-view Recommender System (Recsys) models exploit and combine multiple sources of heterogeneous data (user preferences, profile, contextual information, social trust, text reviews) across recommendation processes to provide end users with improved personalization services. This project aimed at kick-starting a collaboration between Sichuan University (China) and the University of Bristol. It investigates the role and potential benefits of multi-view Recsys approaches in nowadays data-pervaded domains, with particular application interest on personalization for tourism and leisure in smart cities.
Consensus-oriented group recommendation decision-making models and their applications
DSRS members and role: Iván Palomares Carrascosa (co-Investigator)
Type of project and funding body: Young researcher grant (National Science Foundation of China, NSFC). Principal Investigator: Dr. Hengjie Zhang
Group recommendation problems involving a group of users have become a hot topic in the field of Recsys. This project focuses on studying the consensus-based group recommendation problem to help groups of users finding consensual recommendation result(s), with potential decision support applications involving the use of designed Group Recsys approaches e.g. in tourism.
Expansion of Weighted Selective Aggregated Majority-OWA for Heterogeneous Group Decision with Uncertainty Analysis.
DSRS members and role: Binyamin bin Yusoff (Principal Investigator), Iván Palomares Carrascosa (co-Investigator)
Type of project and funding body: Industrial Attachment Programme, University of Malaysia Terengannu. Collaborators: Dr John Cartlidge
Weighted selective aggregated majority-ordered weighted average (WSAM-OWA) is a type of additive aggregation process that extends the majority additive-OWA (MA-OWA). Its main feature is it can be used to model the concept of majority opinion (heterogeneous case) with respect to cardinality of the argument values. The WSAM-OWA is still in its early stage of development and therefore has a lot of room for expansion. By generalizing the WSAM-OWA, a wide range of aggregation operators can be derived and some sets of mathematical properties can be potentially examined. Even though the MA-OWA and WSAM-OWA has been successfully applied in group decision models, it still has some limitations especially in representing the imprecise or uncertain data such as subjective judgments of experts. This project therefore aims at expanding the concept of WSAM-OWA to cope with group decision making under uncertainty.
