Orion is a visual interface for querying ultra-heterogeneous graphs. It iteratively assists users in query graph construction by making suggestions via data mining methods. In its active mode, Orion automatically suggests top-k edges to be added to a query graph. In its passive mode, the user adds a new edge manually, and Orion suggests a ranked list of labels for the edge. Orion’s edge ranking algorithm, Random Decision Paths (RDP), makes use of co-occurring edge sets to rank candidate edges by how likely they will match the user’s query intent. Extensive user studies using Freebase demonstrated that Orion users have a 70% success rate in constructing complex query graphs, a significant improvement over the 58% success rate by the users of a baseline system that resembles existing visual query builders. Furthermore, using active mode only, the RDP algorithm was compared with several methods adapting other data mining algorithms such as random forests and naïve Bayes classifier, as well as class association rules and collaborative filtering based on singular value decomposition. On average, RDP required 40 suggestions to correctly reach a target query graph (using only its active mode of suggestion) while other methods required 1.5–4 times as many suggestions.
