Not just a matter of semantics: the relationship between visual similarity and semantic similarity

open access: yesCoRR, 2018
Knowledge transfer, zero-shot learning and semantic image retrieval are methods that aim at improving accuracy by utilizing semantic information, e.g. from WordNet. It is assumed that this information can augment or replace missing visual data in the form of labeled training images because semantic similarity correlates with visual similarity.
