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 ...

WebIf each Bi-LSTM instance (time step) has an associated output feature map and CRF transition and emission values, then each of these time step outputs will need to be decoded into a path through potential tags and a final score determined. This is the purpose of the Viterbi algorithm, here, which is commonly used in conjunction with CRFs. WebSTM [12,13] or by adding a Conditional Random Field (CRF) layer [14] on top of the BILSTM [15,16,17].
