Abstract: Algorithmic systems that exploit large datasets are increasingly being used to assist or even replace human decision making, a fact that has raised various concerns about the trustworthiness of such systems. Algorithmic fairness addresses such concerns. In this talk, we focus on fairness for graphs and specifically on PageRank fairness. PageRank assigns a score to each node in the graph that signifies the importance of the node. Given that nodes belong to groups, we study fairness in terms of the distribution of the scores assigned to each group. We first present fairness-aware PageRank algorithms that achieve fairness with minimum loss from the original PageRank. Then, we take a different approach where instead of modifying the PageRank algorithm, we ask how to improve the graph. Concretely, we derive analytical formulas for the contribution of each edge to fairness and use them to design link recommendation algorithms for maximizing fairness. We present experimental results using various real and synthetic graphs. We conclude the talk with a list of open problems and promising research directions for algorithmic fairness for both graph and relational data.

The EDBT/ICDT community believes that diversity and culture of support encourage retention and attraction of talent, promote diversity of thought and perspective, and help make the scientific community more flexible and responsive in times of change. However, our conferences still lack diverse voices, and we want to identify the critical barriers to building an inclusive database community.
Therefore, the EDBT/ICDT 2022 panel on Diversity and Inclusion (D&I) is opening borders and is willing to explore the meaning and perception of D&I in scientific contexts across different regions. The EDBT/ICDT D&I panel seeks to have other voices at the table to gain a broader perspective, address challenges, and see solutions from various angles (gender, race, age, experience level, industry, seniority, etc.). The key guiding question is:
What does DnI mean in Europe, Latin America, the Middle East, the north and south of Africa, Asia, Oceania, etc.?
The panel will gather voices from scientists who lead actions and integrate DnI policies into their environment.
