用python编写的文本聚类代码

用python编写的文本聚类代码，部分代码如下： import re # 去除文本中的表情字符（只保留中英文和数字） def clear_character(sentence): pattern = re.compile('[^\u4e00-\u9fa5^a-z^A-Z^0-9]') line = re.sub(pattern, '', sentence) new_sentence = ''.join(line.split()) return new_sentence train_text = [clear_character(data) for data in df["data"]] train_text[:1] #分词的过程较为缓慢，请耐心等待 import jieba train_seg_text = [jieba.lcut(s) for s in train_text] train_seg_text[:1]
