Pre-trained Models

Here, we provide pre-trained models for the GENIA tagger and the NERsuite. The model files for the GENIA tagger are same to the original ones. The pre-trained models for NERsuite are for the tasks such as BioCreative 2 Gene Mention Recognition (BC2GMR) task and NLPBA 2004 Named Entity Recognition (NLPBA04) task.
