Entity Embeddings of Categorical Variables (2016)(About) > We map categorical variables in a function approximation problem into Euclidean spaces, which are the entity embeddings of the categorical variables. The mapping is learned by a neural network during the standard supervised training process. Entity embedding not only reduces memory usage and speeds up neural networks compared with one-hot encoding, but more importantly by mapping similar values close to each other in the embedding space it reveals the intrinsic properties of the categorical variables
Combining word and entity embeddings for entity linking (ESWC 2017)(About) The general approach for the entity linking task is to generate, for a given mention, a set of candidate entities from the base and, in a second step, determine which is the best
one. This paper proposes a novel method for the second step which is
based on the **joint learning of embeddings for the words in the text and
the entities in the knowledge base**.
