Driver Requirements

Driver	Built-in	CkipTagger	CkipClassic
Sentence Segmentation	✔
Word Segmentation†		✔	✔
Part-of-Speech Tagging†		✔	✔
Constituency Parsing			✔
Named-Entity Recognition		✔
Coreference Resolution‡	✔	✔	✔

• † These drivers require only one of either backends.

• ‡ Coreference implementation does not require any backend, but requires results from word segmentation, part-of-speech tagging, constituency parsing, and named-entity recognition.

Installation via Pip

• No backend (not recommended): pip install ckipnlp.

• With CkipTagger backend (recommended): pip install ckipnlp[tagger] or pip install ckipnlp[tagger-gpu].

• With CkipClassic Parser Client backend (recommended): pip install ckipnlp[classic].
