Topic Modeling is a technique to understand and extract the hidden topics from large volumes of text. Latent Dirichlet Allocation(LDA) is an algorithm for topic modeling, which has excellent implementations in the Python's Gensim package. This tutorial t
LDA Topic Modeling(主题建模): 以Rocscience 2021用户会议为例 2 安装BERTopic 由于BERTopic依赖大量的库,为了避免发生冲突,建立了虚拟环境bertpoic, 使用默认安装方式:pip install bertopic;BERTopic也支持Flair嵌入,包括gensim,spacy, 同时需要安装Tensorflow, 使用pip install bertopic[all]命令可以安装全部的后台库,...
After cleaning the extracted data both using the Python text processing toolspaCyand manually, we ascertained the optimal number of topics by drawing on the coherence scores and used latent Dirichlet allocation (LDA) topic modeling to generate the most salient topics and related terms. We then ...
