Transfer Deep Learning for Low-Resource Chinese Word Segmentation with a Novel Neural Network
share
Recent studies have shown effectiveness in using neural networks for Chinese word segmentation. However, these models rely on large-scale data and are less effective for low-resource datasets because of insufficient training data. We propose a transfer learning method to improve low-resource word segmentation by leveraging high-resource corpora. First, we train a teacher model on high-resource corpora and then use the learned knowledge to initialize a student model. Second, a weighted data similarity method is proposed to train the student model on low-resource data. Experiment results show that our work significantly improves the performance on low-resource datasets: 2.3 F-score on PKU and CTB datasets. Furthermore, this paper achieves state-of-the-art results: 96.1
