Processing and Presentation of Knowledge about the Cultural-Historical and Natural Heritage of Bulgaria in an Intelligent Tourist Guide

The report presents a reengineering approach to expand the knowledge base of the intelligent Tourist Guide developed in the DeLC laboratory of Plovdiv University "Paisii Hilendarski" with information about the Bulgarian cultural, historical and natural sites stored in existing non-standardized databases. The Tourist Guide is created as a multi-agent environment based on the reference architecture of the Virtual Physical Space (ViPS). The knowledge base in ViPS is based on a network of ontologies - OntoNet. In order to use the existing databases, it is necessary to create a common database based on the CCO standard (Cataloging Cultural Objects) for the presentation of cultural and historical sites of UNESCO.
