Mulai NLTK v3.3, pengguna harus menghindari penandaan Stanford NER atau POS nltk.tag, dan menghindari Stanford tokenizer / segmenter dari nltk.tokenize.
Alih-alih gunakan nltk.parse.corenlp.CoreNLPParserAPI baru .
Silakan lihat https://github.com/nltk/nltk/wiki/Stanford-CoreNLP-API-in-NLTK
(Menghindari jawaban hanya tautan, saya telah menempelkan dokumen dari NLTK github wiki di bawah)
Pertama, perbarui NLTK Anda
pip3 install -U nltk
Kemudian unduh paket CoreNLP yang diperlukan:
cd ~
wget http://nlp.stanford.edu/software/stanford-corenlp-full-2018-02-27.zip
unzip stanford-corenlp-full-2018-02-27.zip
cd stanford-corenlp-full-2018-02-27
wget http://nlp.stanford.edu/software/stanford-chinese-corenlp-2018-02-27-models.jar
wget https://raw.githubusercontent.com/stanfordnlp/CoreNLP/master/src/edu/stanford/nlp/pipeline/StanfordCoreNLP-chinese.properties
