In reality, however, there are roughly only 26.2% ONE-TO-ONE triplets that are suitable to be modeled by TransE.
the remainder triplets (73.8%) suffer as illustrated on the left hand side of Figure 1, where the tail entities (t 1 , t 2 , ..., t m ) are all pushed into a cramped range because minimizing loss function impels every training triplet to satisfy ||h + r t|| = 0, leading to h 1 = h 2 = ... = h m in the worst case.
