Web3.1 Background: BiLSTM-CRF In the task of named entity recognition, we aim to predict the label sequence y = {y1,y2,··· ,y n} given the input sentence x = {x1,x2,··· ,x n} where n is the number of words. The labels in y are defined by a label set with the standard IOBES1 labeling scheme (Ramshaw and Marcus, 1999; Ratinov and Roth, 2009 ... WebSep 17, 2024 · 1) BiLSTM-CRF, the most commonly used neural network named entity recognition model at this stage, consists of a two-way long and short-term memory network layer and a conditional random field layer. 2) BiLSTM-self-attention-CRF model, a self-attention layer without pre-training model is added to the BiLSTM-CRF model. 3)
