Master's thesis in Data & AI: Fair and trustworthy...

Recommendation systems often favor dominant sellers and ignore user context, leading to biased and irrelevant suggestions. This thesis examines how AI can improve both fairness and trustworthiness in e-commerce recommendations. You'll analyze existing methods, test algorithms on real-world data, and design a solution that balances market visibility with user relevance.

💡 Areas of Interest: artificial intelligence, algorithm design, data science

Recommendation systems are a cornerstone of modern e-commerce platforms. They shape customer behavior, influence satisfaction and directly affect market dynamics. However, the fairness and reliability of these systems are questionable, as studies have shown that many popular algorithms tend to favor products from dominant sellers, creating a biased product offering. This undermines the visibility of smaller vendors and reduces consumer trust.

Additionally, these systems often lack contextual awareness. They may recommend items that have already been purchased or fail to distinguish between multiple users sharing the same account (e.g., family members), leading to irrelevant suggestions. These inefficiencies not only diminish the user experience but also further question the effectiveness of the recommendation engine.

The aim of this thesis is to contribute to the development of fair and trustworthy recommendation algorithms for e-commerce platforms using AI. This assignment addresses both aspects through three main stages:

This thesis should contribute to the academic discourse on fairness in AI, while offering practical insights for improving recommendation systems in online commerce.
