An increasingly large number of sets of linked open data (LOD), typically in RDF format, are being pub-lished on the Semantic Web. Those data represent a potentially valuable resource for data analysis, particularly online analytical processing (OLAP), which often employs multidimensional (MD) models for conducting MD data analysis. Conducting MD analysis over LOD, however, is not a straightforward task. Most analysts will lack the technical skills to query LOD sources using an unfamiliar query language over data in a format not traditionally associated with MD data analysis. In this paper, we introduce the concept of the semantic web analysis graph (SWAG), which allows experts familiar with the LOD source to plot interesting courses of analysis for other users. We present a proof-of-concept prototype. The results of a usability study show that SWAGs may serve to build intuitive user interfaces.
