Tourism sciences represent a very active research field in Computer Science today. In particular, in the realm of ubiquitous computing. The evolution of mobile devices and their proliferation in society, the advancement of communication technologies and the trend toward creating hybrid spaces (symbiosis between nature and technology) will trigger a radical change in the way persons involved in mobility,...
This paper presents a Knowledge Base System (KBS) as a key component of a federated simulation framework which allows the investigation of (inter)dependencies among Critical Infrastructures (CIs). The KBS supports the federated simulation framework by using the ontological formalism to represent specific CI domains and their dependencies. The main advantage of the proposed ontological formalism consists...
This paper explains how a user-generated folksonomy can be aligned with, and used to expand an ontology. The ontology can in turn be used as a backbone for, and visualized through, an interactive tourist city tour on a mobile phone. Furthermore, it suggest that the city tour can be dynamically changed based upon user input through a folksonomy, which has been aligned with the ontology.
Considering the limitation of the traditional and current examination system, this paper brings forward a framework and be used for the general exam system. The general exam system is based on three layers: the user layer, the application logic layer and the data services layer with ontology base, user feature base, method base and knowledge base. In the system, ontology is used to describe the knowledge,...
We present a Web system architecture using ontologies to improve the behavior of the system from the performance viewpoint. Since Web system performance indexes depend on state and parameter values on runtime period, the proposed system configuration will change during this period. In order to perform this change, the Web system is monitorized and gathered information stored into a knowledge base...
