Fig. 2From: A neural joint model for entity and relation extraction from biomedical textThe Bi-LSTM-RNN for biomedical entity recognition. Rectangular grids indicate vectors of feature embeddings or representations. At the bottom, three kinds of vectors are concatenated and fed into LSTMs. Dashed arrow lines denote bottom-up computations along the network framework and solid arrow lines denote left-to-right computations along the sentenceBack to article page
