WebJun 15, 2024 · Methodology. Proposed Chinese NER Model: In this study, we propose a syntactic dependency guided BERT-BiLSTM- GAM-CRF model for the Chinese NER task. The overall structure of the proposed model is shown in Fig. 2. In addition, the overall flow of the algorithm is shown in Table 1. Table 2. WebIn this work, we employ a pre-trained BERT with Conditional Random Fields (CRF) architecture to the NER task on the Portuguese language, combining the transfer capabilities of BERT with the structured predictions of CRF. We explore feature-based and fine-tuning training strategies for the BERT model.
