如何保存输出?我使用以下代码:
%time lda1 = models.LdaModel(corpus1, num_topics=20, id2word=dictionary1, update_every=5, chunksize=10000, passes=100)
答案 0 :(得分:2)
将每个文档的主题混合导出到csv文件:
import pandas as pd
mixture = [dict(lda_model[x]) for x in corpus1]
pd.DataFrame(mixture).to_csv("topic_mixture.csv")
将每个主题的热门词汇导出到csv文件:
top_words_per_topic = []
for t in range(lda_model.num_topics):
top_words_per_topic.extend([(t, ) + x for x in lda_model.show_topic(t, topn = 5)])
pd.DataFrame(top_words_per_topic, columns=['Topic', 'Word', 'P']).to_csv("top_words.csv")
CSV文件将采用以下格式
Topic Word P
