Named Entity Tagger dengan korpus bahasa Indonesia menggunakan nltk ClassifierBasedTagger melakukan klasifikasi bagian kalimat yang merupakan Named Entity nama sesorang, lokasi, organisasi, waktu, dll.

Dependensi python:

• Sastrawi stemmer
• CRFTagger (nltk)

python main.py

1. Fork it!
2. Create your feature branch: git checkout -b my-new-feature
3. Commit your changes: git commit -am 'Add some feature'
4. Push to the branch: git push origin my-new-feature
5. Submit a pull request :D

Hasil train terakhir dicoba tidak terlalu baik, untuk kasus kalimat

Per semester pertama 2004, total utang jangka panjang Telkom sebesar Rp 20,648 triliun.

hasil tag = (S
  (org P/NN s/NNP)
  p/NNP

  (org j/FW)
  (org p/FW)
  (loc T/NNP s/NNP)
  (loc R/NNP 2/CD)
