Δημιουργία Αλληλεπιδραστικού Γραφικού Περιβάλλοντος για την οπτική αναπαράσταση των συσχετίσεων μεταξύ οντολογιών

Abstract

The current paper’s purpose is the creation of an interactive graphical user interface for the visual representation of the correspondences between different Ontologies. This system supports the rules which have been determined by using the Ontology Alignment Tool (OAT) [1]. Furthermore, for the needs of this work and the presentation of the correspondences between different ontologies, we are using models which have been developed in the project HarmonicSS [21] for the ontological representation of data of the patients who come from different institutes as well as the mapping rules which have been determined by using the above tool. In order to implement our system we use modern web technologies both for the creation of the graphical environment (client code) as well as the processing of the data of ontologies and their correspondences (server code). The system is described by detail in structural and functional basis and we make clear how the reader is able to initialize it. The system is distributed for usage as a web application. Through its intensive usage with different data of Ontologies and mapping rules, we reach in conclusions. The evaluation of the system is done based on the 10 usability heuristics of Nielsen [20] for the visual representation of real rules and models which showed the strengths of the system as well as their weaknesses which can be improved in the future.
