TextRank 算法是一种用于文本的基于图的排序算法,通过把文本分割成若干组成单元(句子),构建节点连接图,用句子之间的相似度作为边的权重,通过循环迭代计算句子的TextRank值,最后抽取排名高的句子组合成文本摘要。本文介绍了抽取型文本摘要算法TextRank,并使用Python实现TextRank算法在多篇单领域文本数据中抽取句子组成摘要...
We have successfully analyzed our dataset, in the next section we will create multi-label classification models using this dataset. Creating Multi-label Text Classification Models There are two ways to create multi-label classification models: using a single dense output layer and using multiple dense...

At first, I was using the model below, but it takes too long to process each review text (I need to process around 5k to 10k reviews daily). classifier = pipeline("zero-shot-classification", model="MoritzLaurer/mDeBERTa-v3-base-mnli-xnli") ...
