An Ontology for Representing and Extracting Knowledge Starting from Open Data of Public Administrations

摘要

As proposed by European Commission through the institution of Europe's Digital Agenda, the Italian Digital Agenda has promoted the publication and the use of Open Data (OD) owned by the Public Administration (PA), providing with the appropriate guidelines for describing and managing Open Data under criteria of transparency, usability, accessibility. Inail (Italian Institute for Insurance against Accidents at Work) has recently started to publish periodically OD related to occupational accidents and diseases. The Inail OD, as they are defined, are mainly suitable for statistical studies but together with the vocabulary and the typological tables, that explicitly describe some codes in the dataset, it has been possible to develop a conceptual model which may be linked to schemas provided by other PA's for achieving the interoperability among those data through their semantics. Starting from the OD on occupational accidents, an ontology has been developed for capturing the meaning (semantics) of information, both contained into the OD available from Inail and defined in the vocabulary. The formalism of the ontology adopted for representing the knowledge, in terms of concepts and their relations, ensures to share a common language avoiding misinterpretations and misunderstanding.
