AirBase is the European air quality dataset maintained by the EEA (Environmental European Agency). The dataset is publicly available on the Web, and contains air quality monitoring data for 40 European countries. The multidimensional nature of the data makes it a good fit for OLAP (Online Analytical Processing) systems. These systems are optimized for complex queries with aggregation and grouping on multidimensional data, which are common in data analysis. Moreover, by linking the data to existing knowledge bases in the Semantic Web, we can magnify its value, allowing for more sophisticated data analytics. Based on these observations, we introduce and describe QBAirbase, a multidimensional provenance-augmented version of the Airbase dataset. QBOAirbase represents air pollution information as an RDF data cube, which has been linked to the YAGO and DBpedia knowledge bases. QBOAirbase is based on the version 8 of the Airbase dataset.
