Abstract
We present a UML class diagram style notation for data analysis SPARQL query definition and its implementation in the ViziQuer tool that provides query definition environment and query translation into SPARQL 1.1. The notation and its implementation within the tool allows for rich value selection and condition expression language, as well as integrated data aggregation facilities, both essential for data analysis query definition.
