One application of text analytics and NLP is Text Summarization. With the overwhelming amount of new text documents generated daily in different channels, such as news, social media, and tracking systems, automatic text summarization has become essential for digesting and understanding the content. However, not everyone can read the entire document. You'll not have to do it for this week's assignment, but it's good that you have this in mind for your own applications. Natural language processing shows a great role in machine-human interaction. It is still in progress and more researches are being carried in this sector. We could expect to see a more smart and perfect text summarization technique in future that will understand human language and work accordingly. Text Summarization Python helps in summarizing and shortening the text in the user feedback. And all other numbers for the tokens for different words.

But the one thing may immediately stand out to you. Summarizing text can be expensive and time-consuming if done manually. Let's dive in. Types of Text Summarization. The method is based on inverse sentence frequency and weighted term-frequency paradigm. Here is an example of how to create inputs features for training the transformer from an article and its summary. the task of automatically generating a shorter version of a document while retaining its most important information. So the cost function is a cross entropy function that ignores the words from the article to be summarized. Top-ranked sentences create the final summary. In simple terms text summarization is converting a longer text/document into a short version while keeping safe the actual objective of text. Before you read this you must have knowledge of NLP (Click Here)What is Text Summarization ?

Then you will ask for the next word, and the next, and so on until you get the EOS token. In this video, I'll show you how to make a summarizer. Thankfully – this technology is already here.

Instead of averaging the loss for every word in the whole sequence, you weight the loss for the words within the article with 0s, and the ones within the summary with 1s. You will use the transformer built in the last video and put it to work. In addition to text, images and videos can also be summarized. However, when there is little data for the summaries, it's actually helps to weight the article loss with nonzero numbers say 0.2 or 0.5 or even 1.
