Hence we are using the find_all function to retrieve all the text which is wrapped within the

tags. If it doesn’t exist, then insert it as a key and set its value to 1. The algorithm does not have a sense of the domain in which the text deals. If it is already existing, just increase its count by 1. Where is link to code? fit_on_texts (list (x_tr)) #convert text sequences into integer sequences (i.e one-hot encodeing all the words) x_tr_seq = x_tokenizer. summary_text = summarization(original_text)[0]['summary_text']print("Summary:", summary_text) Note that the first time you execute this, it’ll download the model architecture and the weights, as well as tokenizer configuration. We are not considering longer sentences hence we have set the sentence length to 30.
