Abstract

The provision of publicly available open data leads to transparency in several public sector exchanges, spending and decisions. However, this information is served massively and heterogeneously - mostly due to different bureaucratic procedures and paperwork formats, while its diffusion does not occur at regular or at least generally predictable time intervals. Thus, even though the information is available by the involved public sectors, enterprises and citizens are overwhelmed from the size/inconsistency of the information they deal with. The scope of our publicly accessible Web point is two-fold. Firstly, it aims to promote clarity and enhance citizen awareness regarding public spending in Greece through easily consumed visualization diagrams. Information provision is based on semantic processing of real-time open data provided by Greek government ('Diavgia') and the Greek Taxation Information System. Secondly, a proposed ontology for public spending in Greece functions in two distinct levels. It checks the validity of the publicly available data accessed by the system, cleaning and reconstructing in parallel false entries, while it will interconnect the data to existing ontological and data schemes derived from other similar initiatives worldwide and core vocabularies.

Keywords: open data, e-government, public expenditure, ontologies, citizen empowerment, data journalism
