Abstract: With the recent growth of bibliographic data, many research fields work on defining new techniques for their analysis. In this context, data could be represented as heterogeneous networks. In order to analyse information networks in a multidimensional way, online analytical processing (OLAP) may be a relevant solution but it must be adapted for networked data by considering nodes and edges. A first approach that has been proposed in the literature consists in building cubes of graphs. In a different and complementary way, our proposal consists in enriching graphs with cubes. Indeed, the nodes or/and edges of the considered network are described by a cube. It allows interesting analyses for the user who can navigate within a graph enriched by cubes according to different granularity levels, with dedicated operators. We implemented our approach and performed an experimental study on a real dataset to show the interest of our proposal.

Keywords: online analytical processing; OLAP; bibliographic networks; data cubes; graph databases; graphs.
