Loch Prospector: Metadata Visualization for Lakes of Open Data

Abstract

Figure 1: LOCH PROSPECTOR visualizes available datasets in Open Data lakes using four linked components. A multidimensional scaling (MDS) [16] plot 1 shows a point for each dataset, organized spatially by similar metadata characteristics. Weights for the MDS algorithm can be tuned for particular types of metadata using the Visualization Configuration Box 2 . Dynamic Filters [2] 4 can be used to explore datasets of interest, with Summary Statistics 3 shown for the currently selected datasets.
