Ontology based road service task manager and route planning system

Recent developments in technology and industry show that users are increasingly becoming the focus of technological development. Not only new applications capable of performing certain tasks are brought to potential users, but also technical innovations that are built around people in order to best fit their needs and make their lives easier. In this paper, we discuss in detail our newly developed concept of an ontology based context - aware road servicing task manager and route planning system. The ontology is a data model which defines a set of concepts within a certain domain and describes the relationships between those concepts. By using ontology to model resources, humans and computers (software agents) can have a consensus on the resource structure. We modelled upper - level road segment domain ontology by using OWL (Web Ontology Language) and proposed a system which integrates GPS, ontology and agent technologies to support location and status awareness for providing an optimal, dynamically adaptive, route plan for the road servicing units. The architecture of such system, including the relations between data sources and user services, and data flow procedures is explained in the following chapters.
