For example, relations inherently have domain and range which will contribute much towards learning, even though sometimes they are not explicitly given in knowledge graphs. In this paper, we propose a framework TransX\\(_C\\) (X can be replaced with E, H, R or D) to help preserve ...

Next, various operations on binary relations are explained; beyond Boolean operations such as union, intersection and complementation these are the composition of relations, the converse of a relation and the domain and range of a relation. After that, special binary relations, such as reflexive ...
Domain and Range of Relations • Let R A B, then –The domain of R, Dom(R) is defined as: {x|x A, and exists some y B, such that xRy} –The range of R, Ran(R) is defined as: {y|y B, and exists some x A, such that xRy} –Note: Dom(R) A, and, Ran(...

Several word embedding models could be used simultaneously: e.g., general model with a large dictionary and domain-specific model with smaller dictionary but better in-domain similarity.Currently word2vec, GloVe, fastText and TDozat word embedding models are supported. word2vec and GloVe ...
