AutoPhraseX

Python package PyPI version Python

Automated Phrase Mining from Massive Text Corpora in Python.

实现思路参考 shangjingbo1226/AutoPhrase,并不完全一致。

安装

pip install -U autophrasex

使用

from autophrasex import AutoPhrase, BaiduLacTokenizer, Strategy

tokenizer = BaiduLacTokenizer()
strategy = Strategy(
    tokenizer=tokenizer,
    N=4,
    threshold=0.45,
    threshold_schedule_factor=1.0)

autophrase = AutoPhrase()
predictions = autophrase.mine(
    input_doc_files=['/path/to/doc/files'],
    quality_phrase_files=['/path/to/quality/phrase'],
    strategy=strategy,
    N=4,
    epochs=10)

for pred in predictions:
    print(pred)
