Before revision:  To mitigate this problem, we propose PairRE, a model with improved expressiveness and low computational requirement. PairRE represents each relation with paired vectors , where these paired vectors project connected two entities to relation specific locations. Beyond its ability to solve the aforementioned two problems ,
After revision:  To mitigate this problem, we propose PairRE, a model with paired vectors for each relation representation. The paired vectors enable an adaptive adjustment of the margin in loss function to fit for complex relations. Besides ,
