内容深化

话题建模

使用话题建模技术识别内容主题和趋势

话题建模概述

话题建模自动识别文档主题[1],发现隐藏模式[2],指导内容策略[3]

核心算法

LDA(Latent Dirichlet Allocation)[4]

  • 概率主题模型、文档-主题分布、主题-词分布

NMF(Non-negative Matrix Factorization)[5]

  • 矩阵分解、非负约束、主题提取

BERTopic[6]

  • 基于BERT、聚类方法、动态主题

应用场景

内容分析[7]

  • 主题识别、趋势发现、内容分类

策略规划[8]

  • 主题缺口、内容机会、优先级排序

竞品分析[9]

  • 主题对比、覆盖度分析、差异化机会

工具支持

Python库[10]

  • Gensim、scikit-learn、BERTopic
