Project description
Towards trustworthy and transparent intelligent group recommender systems
E-commerce ecosystems and social media platforms employ intelligent tools for content recommendations and post moderation. Group recommender systems (GRS) are gaining popularity, but the demand for greater transparency in the algorithms and decision-making processes has a negative impact on job opportunities, e-commerce, and exposure to news. Ensuring fairness and explainability is crucial to establish transparency and build trust in AI-based systems like GRS. However, while traditional individual recommender systems (RS) have made efforts to enhance these aspects, they have yet to be explored in GRS. The MSCA-funded FIDELITY project is devoted to developing new algorithms and tools to improve explanation, fairness, and synergy within GRS. The project incorporates post hoc explanation techniques to bridge the gap between explanation and fairness in RS and GRS.
Objective
Today, most social media networks use automated tools to recommend content or products and to rank, curate and moderate posts. Recommender systems (RSs), and in particular Group recommender systems (GRSs), -a specific kind of RSs used to recommend items to a group of users-, are likely to become more ubiquitous, with expected market forecast to reach USD 16.13 billion by 2026.
These automated content governance tools are receiving emerging interest as both algorithms and decision-making processes behind the platforms are not sufficiently transparent, with a negative impact on domains such as fair job opportunities, fair e-commerce or news exposure.
Two of the key requirements that have to be fulfilled to build and keep users’ trust in AI systems while guaranteeing transparency are Fairness and Explainability. But, aside from some previous attempts to enhance both aspects in traditional-individual RS, they have hardly been explored in GRSs.
FIDELITY addresses this challenge by developing novel algorithms and computational tools in GRS to boost explanation, fairness, and synergy between them through a disruptive multidisciplinary research approach that: 1) extensively brings SHAP and LIME, as state-of-the-art post-hoc explanation approaches in AI, into RS and GRS contexts, 2) bridges explanation and fairness in RS and GRS, introducing an explanation paradigm shift moving from “why are the recommendations generated?” to “how fair are the generated recommendations?” and, 3) transversally evaluates the new methods through real-world GRSs and user studies. The ultimate goal is to guarantee greater user trust, and independence of RS output from any of the sociodemographic characteristics of users. The training programme, designed with the aim to fill the existing gaps between computing science, social research and business development reality, will provide the candidate with a multidisciplinary background that will boost his innovation potential and career prospects.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
