Users’ preferences have traditionally been exploited in query personalization to better serve their information needs. Most of the time, user preferences depend on context, that is, they may have different values depending on the situation of the u

In this chapter, we provide a brief overview of recent research works based on fuzzy set theory that aim to make data management systems more flexible. Three aspects are considered: (i) preference queries to classical databases, (ii) modeling and han

International audience; A DB querying system is said to be flexible if it adapts to the end user expectations and expertise. This paper introduces a novel strategy to fuzzy querying that reduces the gap between complex search conditions end users hav

Imprecise and subjective concepts, as e.g. promising students, may be used within data mining tasks or database queries to faithfully describe data properties of interest. However, defining these concepts is a demanding task for the end-user. We thus
