Personalization, Bias and Privacy by Prof. Ricardo Baeza-Yates, Northeastern University at Silicon Valley
Abstract: Personalization can be seen as a positive bias towards each user. However, it also has negative consequences such as privacy loss as well as the filter bubble effect due to the feedback-loop that creates. In addition, the web system itself can bias the user interaction distorting the data used for personalization, particularly due to exposure bias. Our own biases also affects the personalization process, especially activity bias. Privacy also depends on the personalization level and the personalization level depends on the amount of interaction data available. In this presentation we discuss the interaction of these three elements: personalization, bias and privacy.
