Chinese word segmentation: 20 points

• This task provides PKU data as training set and test set (e.g., you can use 80% data for model training and other 20% for testing ), and you are free to use data learned or model trained from any resources.
• Evaluation Metrics:
  • Precision = (Number of words correctly segmented)/(Number of words segmented) * 100%
  • Recall = (Number of words correctly segmented)/(Number of words in the reference) * 100%
  • F measure = 2PR / (P+R)
