Querying Knowledge Graphs by Example Entity Tuples
GQBEruns queries on knowledge data graphs. A datagraph is a directed multi-graph G with node set V(G) and edge set E(G). Each node v∈V(G)represents an entity and has a unique identifier id(v). 2 Each edge e=(v i,v j)∈E(G)denotes a directed relationship from entity v i to entity v j. It has a label, denoted as label(e). Multiple edges can ...

More formally, let T be a minimum spanning tree for Gwith edge
