6.1 Introduction

6.1.1 What Is Mobility Data Mining?

The trajectories of a moving object are a powerful summary of its activity related to mobility. As seen in Chapters 3 and 4, such information can be queried in order to retrieve those trajectories (and the objects that own them) that respond to some given search criteria, for instance following a predefined interesting behavior. However, when massive amounts of information are available, we might be able to move a step further and ask that such “interesting behaviors” automatically emerge from the data. That is precisely the domain explored by mobility data mining.

Moving from queries to data mining essentially consists of adding degrees of freedom to the ...
