Keep in mind that text classification is an art as much as it is a science. Your creativity when it comes totext preprocessing,evaluation and feature representation will determine the success of your classifier. A one-size-fits-all approach is rare. What works for this news categorization task...
Preprocessing Performing basic preprocessing steps is very important before we get to the model building part. Using messy and uncleaned text data is a potentially disastrous move. So in this step, we will drop all the unwanted symbols, characters, etc. from the text that do not affect the o...

本文将使用 Python 实现和对比解释 NLP中的3 种不同文本摘要策略:老式的 TextRank(使用 gensim)、著名的 Seq2Seq(使基于 tensorflow)和最前沿的 BART(使用Transformers)。 NLP(自然语言处理)是人工智能领域,研究计算机与人类语言之间的交互,特别是如何对计算机进行编程以处理和分析大量自然语言数据。最难的 NLP 任务...
