ckipnlp.driver.tagger module

This module provides drivers with CkipTagger backend.

class ckipnlp.driver.tagger.CkipTaggerWordSegmenter(*, lazy=False, disable_cuda=True, recommend_lexicons={}, coerce_lexicons={}, **opts)[source]

Bases: ckipnlp.driver.base.BaseDriver

The CKIP word segmentation driver with CkipTagger backend.

Parameters
  • lazy (bool) – Lazy initialize the driver.

  • disable_cuda (bool) – Disable GPU usage.

  • recommend_lexicons (Mapping[str, float]) – A mapping of lexicon words to their relative weights.

  • coerce_lexicons (Mapping[str, float]) – A mapping of lexicon words to their relative weights.

Other Parameters

**opts – Extra options for ckiptagger.WS.__call__(). (Please refer https://github.com/ckiplab/ckiptagger#4-run-the-ws-pos-ner-pipeline for details.)

__call__(*, text)

Apply word segmentation.

Parameters

text (TextParagraph) — The sentences.
