In this project, our goal is to enable business intelligence over semantic data. This includes not only making new datasets available as Linked Open Data but also developing strategies for efficient execution of analytical queries.
The dataset (GovAgriBus) used in JIST'14 can be accessed at our public endpoint through the following named graphs (Graph IRIs). You can download the corresponding graph data from the download links.

The dataset (GeoNorthwind) used in JIST'15 and Semantic Web Journal'17 can be accessed at our public endpoint through the following named graphs (Graph IRIs). You can download the corresponding graph data from the download links.

The dataset (GeoFarmHerdState) used in JIST'16 can be accessed at our public endpoint through the following named graphs (Graph IRIs). You can download the corresponding graph data from the download links.

The dataset (GeoFarm) is an alternative version of GeoFarmHerdState data set focusing on the spatial attributes of the cube. The data sets are annotated with QB4OLAP before enrichment as input data. Afterwards, the data sets are enriched and annotated with QB4SOLAP as output data. These data sets are used in SWJ'19, and can be accessed at our public endpoint through the following named graphs (Graph IRIs). You can download the corresponding graph data from the download links.
