We show that symmetry and transitivity together are sufficient to guarantee that the .-error can be computed in polynomial time. However, dropping either of them makes the problem .-complete.

The summary graph can be used to analyze the namespace inter-dependencies of the original graph. We also present ., a tool for calculating namespace-based KG summari

mender system is a powerful information filtering tool to support user interaction and promote products. Dealing with determining customer interests, graph-based collaborative filtering is recently the most popular technique. Its only drawback is high computing cost, leads to bad scalability and inf

It is known that the .-error can be computed in polynomial time if
