cntopic icon cntopic

简单好用的lda话题模型,支持中英文。该库基于gensim和pyLDAvis,实现了lda话题模型及可视化功能。

constructedcodelda icon constructedcodelda

对小数据集进行LDA处理,并利用pyLDAvis可视化。保存模型并进行预测,保存预测结果

keyword_extraction icon keyword_extraction

利用Python实现中文文本关键词抽取,分别采用TF-IDF、TextRank、Word2Vec词聚类三种方法。

lda-based-on-partition-plda- icon lda-based-on-partition-plda-

提出基于划分的LDA主题模型 (PLDA)。对传统LDA模型进行改进,考虑中长篇文档篇章结构较为清晰,传统LDA在处理中长篇文档时不能识别每个篇章的主题,提出基于划分的LDA主题模型,对中长篇文档如新闻报道】国务院工作报告等按照段落进行划分,先拆后合,并将其效果与传统LDA、LSI及doc2vec进行比较。基于Sougou和Fudan语料库的分类实验验证了PLDA效果最优。
