LTP 4

LTP(Language Technology Platform) 提供了一系列中文自然语言处理工具,用户可以使用这些工具对于中文文本进行分词、词性标注、句法分析等等工作。

If you use any source codes included in this toolkit in your work, please kindly cite the following paper. The bibtex are listed below:

@article{che2020n,
  title={N-LTP: A Open-source Neural Chinese Language Technology Platform with Pretrained Models},
  author={Che, Wanxiang and Feng, Yunlong and Qin, Libo and Liu, Ting},
  journal={arXiv preprint arXiv:2009.11616},
  year={2020}
}

快速使用

from ltp import LTP

ltp = LTP()  # 默认加载 Small 模型
seg, hidden = ltp.seg(["他叫汤姆去拿外衣。"])
pos = ltp.pos(hidden)
ner = ltp.ner(hidden)
srl = ltp.srl(hidden)
dep = ltp.dep(hidden)
sdp = ltp.sdp(hidden)
