We show that the BI-LSTM-CRF model can efficiently use both past and future input features thanks to a bidirectional LSTM component. It can also use sentence level tag information thanks to a CRF layer.
WebDec 9, 2024 · I have built a Bi-lstm model for NER Tagging and now I want to introduce CRF layer in it.
