Motif analysis is one main approach to understanding the topology of a network. In bipartite networks, a biclique is one of the most important structural patterns. In the interface pane (c), there is a Detail View 302, and an overview 303 provided in interface pane (d) for browsing the motifs at different scales. These two views offer the visual exploration of all bicliques detected in the network, and the investigation of the changes of results if certain missing links are added. In the Motifs Detail View 302, bicliques are shown as small multiples of matrices in similar visual encodings with the Network View 300. Essentially, a biclique is a portion of the bi-adjacency matrix of the entire network. In addition, the Motifs Overview 303 displays all the bicliques as dots in a two-dimensional space based on the Multidimensional scaling (MDS) projection. The distance between two bicliques is measured with the sum of the Jaccard distance between their node sets of each type.
To support the comparison of two sets of bicliques detected in the networks with and without added links by an analyst, the Motifs Detail View 302 organizes the bicliques in three columns: removed bicliques, newly-added ones, and unchanged ones, compared to the biclique set of the original network; they are in borders represented by different colors (e.g., red, green, and gray). In each column, the default order of bicliques is by size, which can be changed to other sorting criteria. Similarly, the Motifs Overview 303 encodes these bicliques in the three different colors.
