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...
It is fast and preserves all information but can only be processed by Python. âPicklingâ a data frame is easy; you just need to specify the filename: df.to_pickle("reddit_dataframe.pkl") We prefer, however, storing dataframes in SQL databases because they give you ...
Chapter 1. Gaining Early Insights from Textual Data One of the first tasks in every data analytics and machine learning project is to become familiar with the data. In fact, … - Selection from Blueprints for Text Analytics Using Python [Book]

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 ...
