WebJul 1, 2024 · The CRF model Conditional random field (CRF) is a statistical model well suited for handling NER problems, because it takes context into account. In other words, when a CRF model makes a prediction, it factors in the impact of neighbouring samples by modelling the prediction as a graphical model.
