ONTOLOGY-DRIVEN CONCEPTUAL MODEL AND DOMAIN ONTOLOGY FOR EGYPTIAN E-GOVERNMENT

: In recent years, online services have received considerable attention worldwide. One crucial online service during the coronavirus disease (COVID-19) pandemic was e-governance. In which governments provides various services to their citizens using information and communication technology. However, the residents of Arab countries have faced numerous of obstacles and have not received the full benefits of e-governance. One of the main reasons is the absence of integration and information sharing. Therefore, in this study, a novel domain ontology for the Egyptian e-government has been proposed. The developed ontology can be used to solve a variety of interoperability problems. The development process starts with building ontology-driven conceptual model using OntoUML. It is one of the most used ontology-driven conceptual modeling languages. The proposed model is then converted to a computable web ontology via the Web Ontology Language. The resulted ontology is evaluated by the OntoMetrics quality metrics. Results are compared with the metrics collected from 20 e-government ontologies and proved that the proposed ontology has better understandability measurements.
