11.1 INTRODUCTION

Due to the recent developments in mobile devices and GPS systems and the progress of network technology, mobile computing has become a key technology today. Along with the progress in mobile technologies, research on moving object databases is currently being actively investigated in the area of database research [16]. As its name suggests, a moving object database is a database that stores and manages information on moving objects such as vehicles, pedestrians with mobile devices, and so on. Various research and development efforts regarding moving object databases have been conducted, including several topics such as data models for representing movement behaviors appropriately, query processing and indexing methods for answering queries efficiently, and application technologies that utilize the underlying moving object databases effectively.

In this chapter, we focus on data mining technology for moving object databases. Since the middle of the 1990s, data mining research has been growing rapidly and it has become one of the main research fields in computer science [25, 56]. Although data mining research has been expanding in a variety of fields in recent years, data mining technology for moving object databases are still in an emerging stage of development. However, it is highly promising because many moving objects can be monitored in real-time using current mobile information technologies. Since data managed in a moving object database are highly dynamic ...
