The represented knowledge is often context-dependent, leading to the construction of contextualized KGs. The multidimensional and hierarchical nature of context invites comparison with the multidimensional OLAP cube model from data analysis. Traditional systems for online analytical processing (OLAP) employ cube models to represent numeric values for further analysis using dedicated query operations. In this paper, along with an adaptation of the OLAP cube m...
