课程简介: | Linked open data about public contracts can be valuable for both enterprises and public bodies. One of the aims of the EU LOD2 project is to make public contract data available as linked data, with the help of a Public Contracts Ontology, and to apply analytic methods on the top of such data. A wide range of analytical (data mining) methods is being applied, currently on Czech and Polish data, including both descriptive and predictive approaches, and both directly on RDF data and on (interlinked) data transformed back to tabular format. |
