We introduce a storage scheme that allows the representation and management of the evolving hierarchical structure of a multi-version ontology in a temporal relational database. The proposed scheme is aimed at supporting ontology-based personalization and temporal access to large collections of resources (data, documents, procedures etc.) stored in a dynamic environment. Whereas in previous works we considered tree-shaped ontologies only, in this work we consider ontologies with a class hierarchy structured as a general directed graph, that is also supporting multiple inheritance and intersection classes. We will also show how multi-version ontologies must be dealt with for the processing of ontology-based personalization queries.

Dynamic Class Hierarchy Management for Multi-version Ontology-based Personalization

Abstract

We introduce a storage scheme that allows the representation and management of the evolving hierarchical structure of a multi-version ontology in a temporal relational database. The proposed scheme is aimed at supporting ontology-based personalization and temporal access to large collections of resources (data, documents, procedures etc.) stored in a dynamic environment. Whereas in previous works we considered tree-shaped ontologies only, in this work we consider ontologies with a class hierarchy structured as a general directed graph, that is also supporting multiple inheritance and intersection classes. We will also show how multi-version ontologies must be dealt with for the processing of ontology-based personalization queries.
