Abstract

Open Government data present valuable knowledge that supports political, social, and economic value creation. The number of available OGD datasets has increased significantly with pressure being put on government administrations to open up their data. This makes the task of discovering relevant datasets difficult and time-consuming. Improving data discoverability has a significant impact in improving OGD usage. As improving discoverability relies on improving metadata representation, we explore in this paper the usage of ontologies as a knowledge representation formalism to provide a rich and semantically enhanced representation of OGD metadata that enables its processability and interpretability by machines. Our knowledge representation model covers the essential kinds of knowledge necessary for the description of OGD datasets (descriptive, technical, contextual and structural). Based on the semantic model, we propose an approach to transform OGD metadata in a semantically enhanced RDF graph. This graph will serve as a ground basis to implement a semantic search mechanism to improve data discoverability on OGD portals.
