  Chinese word segmentation (CWS) is an important task for Chinese NLP.
Recently, many neural network based methods have been proposed for CWS.
However, these methods require a large number of labeled sentences for model
training, and usually cannot utilize the useful information in Chinese
dictionary. In this paper, we propose two methods to exploit the dictionary
information for CWS. The first one is based on pseudo labeled data generation,
and the second one is based on multi-task learning. The experimental results on
two benchmark datasets validate that our approach can effectively improve the
performance of Chinese word segmentation, especially when training data is
insufficient.
