Bias on Search and Recommender Systems

by Ricardo Baeza-Yates (NTENT & Northeastern University, USA)

In this presentation we cover all biases that affect search and recommender systems. They include biases on the data, the algorithms as well as the user interaction, in particular the ones related to relevance feedback loops (e.g., ranking and personalization). In each case we cover the main concepts and when known, the techniques to ameliorate them, as well as biases that might be product of the evaluation methods used. This presentation is partially based on Bias on the Web, Communications of the ACM, June 2018.
