,可以通过以下步骤实现:
import pandas as pd
from gensim.models.phrases import Phrases, Phraser
data = {'text': ['I love to play football', 'She likes to play basketball', 'He enjoys playing tennis']}
df = pd.DataFrame(data)
def preprocess_text(text):
sentences = text.lower().split('.')
return [sentence.split() for sentence in sentences]
df['sentences'] = df['text'].apply(preprocess_text)
sentences = df['sentences'].tolist()
phrases = Phrases(sentences, min_count=1, threshold=1)
phraser = Phraser(phrases)
df['phrases'] = df['sentences'].apply(lambda x: phraser[x])
print(df['phrases'])
这样,你就可以使用apply方法在pandas列上使用gensim短语了。apply方法可以将自定义的函数应用到DataFrame的列上,而gensim的Phrases模型可以用于检测和提取短语。通过将短语模型应用到列中的句子列表,可以将常见的短语组合识别出来,从而提高文本处理的效果。
