Using the Semantic Web for the Integration and Publication of Public Procurement Data
Public procurement is an activity that is common to all administrations, with a major impact on their functioning and that also affects the economy as a whole. This paper presents an experience that shows how the Semantic Web provides appropriate resources to develop data models that can be used both for the management of public contracts and for the publication of information about them. And within that, with a dual objective of improving efficiency by facilitating competitive tendering, and of making easy the monitoring of public contracts by citizens. Firstly, we developed the PPROC ontology in said experience, with the domain of the ontology being the legal institution of public contracting, which includes the procedure for the preparation of contracts. Next, we used the ontology as a basis for the integration and publication of data from various Spanish administrations.
