Combining Heterogeneous Models for Measuring Relational Similarity
... The rationale behind this variant is as follows. Because the difference of two word vectors reveals the change from one word to the other in terms of multiple topicality dimensions in the vector space, two word pairs having similar offsets (i.e., being relatively parallel) can be interpreted as they ...
