pos

pos

The process of classifying words into their parts of speech and labeling them accordingly is known as part-of-speech tagging, POS-tagging, or simply tagging.

To tag a tokenized sentence:

Batching is Faster

Hint

Tag multiple sentences at once for faster speed!

import hanlp

pos = hanlp.load(hanlp.pretrained.pos.CTB9_POS_ELECTRA_SMALL)
pos(['我', '的', '希望', '是', '希望', '世界', '和平'])

['PN', 'DEG', 'NN', 'VC', 'VV', 'NN', 'VA']
