nlpcc2016-chinese-weibo-segmentation

Long Short-Term Memory (LSTM) based model for the NLPCC 2016 shared task - Chinese Weibo word segmentation. The model got 1st place in close and semi-open track. For more details, refer to our paper Recurrent Neural Word Segmentation with Tag Inference.

Requirement

• Theano
• Lasagne

Notes

• The original dataset for this task should be requested by filling up a Agreement Form. So here we only provide a few examples.
• Once the original dataset is obtained, one should change the space-splited format to BMES tagging format.
• To get the unsupervised features, use scripts by Wu et al., 2014 CistSegment.

Run

• Preparing the data (see the Notes)
• run the script ccl_nlpcc.py
• run the script chunkvec_inference.py
