SuPar-Kanbun

Tokenizer, POS-Tagger and Dependency-Parser for Classical Chinese Texts (漢文/文言文) with spaCy, Transformers and SuPar.

Basic usage

>>> import suparkanbun
>>> nlp=suparkanbun.load()
>>> doc=nlp("不入虎穴不得虎子")
>>> print(type(doc))
<class 'spacy.tokens.doc.Doc'>
>>> print(suparkanbun.to_conllu(doc))
# text = 不入虎穴不得虎子

suparkanbun.load() has two options suparkanbun.load(BERT="roberta-classical-chinese-base-char",Danku=False). With the option Danku=True the pipeline tries to segment sentences automatically. Available BERT options are:

• BERT="roberta-classical-chinese-base-char" utilizes roberta-classical-chinese-base-char (default)
• BERT="roberta-classical-chinese-large-char" utilizes roberta-classical-chinese-large-char
• BERT="guwenbert-base" utilizes GuwenBERT-base
• BERT="guwenbert-large" utilizes GuwenBERT-large
• BERT="sikubert" utilizes SikuBERT
• BERT="sikuroberta" utilizes SikuRoBERTa
