The present study focuses on spatiotemporal historical data organized in an OWL Protégé ontology environment. It aims at exploring the possibilities of using deduction logic tools in correlating alternate names of geographic regions related to time periods and presenting spatiotemporal interconnections. The application paradigm includes spatial data of local regions and sites of contemporary Greece and Turkey related to Hellenic historical archaeological sites temporally distributed in an extended period from Neolithic Age to the 19th century. The results are presented through advanced visualization tools embedded in the Protégé environment.Purpose: The present study focuses on spatiotemporal historical data organized in an OWL Protégé ontology environment. It aims at exploring the possibilities of using deduction logic tools in correlating alternate names of geographic regions related to time periods and presenting spatiotemporal interconnections.Design/methodology/approach: Methodology follows the systematic review paradigm and includes the development of a protocol for the following elements. Protocol for the inclusion of different types of entities. Protocol for the ways of standard use and expansion, in this case TNG and AAT vocabularies. Protocol for the description of entities within the ontological framework and finally a set of rules for the selection of vocabularies and authority tools. Literature search was conducted grouped in units to the corresponding protocols and likewise research results were tested per protocol.Findings: The central idea of this study was the exploitation of embodied Deduction Logic tools in an ontology …
