抄録: | This paper presents a semi-supervised co-training approach for discriminative sequential learning models, such as conditional random fields (CRFs). In this framework, different CRF models are trained on an initial set of sequence data according different views. The bootstrapping process is performed by iteratively adding new reliably inferred data sequences to the training data sets of CRF models retraining them. Reliable data sequences are inferred from a huge set of unlabeled data by estimating entropy values of predicted labels at time positions in data sequences. The inference and re-train operations are repeated a number of times in order that each CRF model should gain as much useful evidence from unlabeled data and the other CRF models as possible. The proposed method was tested on noun phrase chunking and achieved significant results. |
