Word Sense Disambiguaion by Chinese Word Net

Chinese word sense disambiguation has been known to a very difficult problem since Chinese is a complicated language. A word can have dozens or even hundreds of meanings on different occasions. Manually labels the senses of the words is labor-intensive and inefficient.

In this project, we aim to solve this problem by state-of-the-art Bert model. It gives us huge performance gains and can score roughly 82% accuracy on Chinese word sense disambiguation problem.

Prerequest

• Input should be tokenized first. POS Tagging is preferred but not required.
• Suppose we have m sentences and each sentence has $n_m$ words.

  • list_of_sentence[ [list_of_word[[target, pos, sense_id, sense] * $n_m$ ] *m ]

  • The following is an example that has 2 sentences, input data should be formed as following

      [[["他","Nh","",""],["由","P","",""],["昏沈","VH","",""],["的","DE","",""],["睡夢","Na","",""],["中","Ng","",""],["醒來","VH","",""],["，","COMMACATEGORY","",""]],
       [["臉","Na","",""],["上","Ncd","",""],["濕涼","VH","",""],["的","DE","",""],["騷動","Nv","",""],["是","SHI","",""],["淚","Na","",""],["。","PERIODCATEGORY","",""]]]
    

How to get sense

• At Project root directory (same as setup.py)

    pip3 install .
    import CWN_WSD
    data = read_somewhere() #list of sentence, and sentence is composed as list of word
    sense = CWN_WSD.wsd(data)
  

• example can be found under example folder
