![]() Ease is a greater threat to progress than hardship. So, keep moving, keep growing, keep learning. Similarly, you can add the sentence with the second highest sum of weighted frequencies to have a more informative summary. You can easily judge that what the paragraph is all about. For instance, look at the sentence with the highest sum of weighted frequencies: The sentences with highest frequencies summarize the text. The final step is to sort the sentences in inverse order of their sum. Sort Sentences in Descending Order of Sum So, keep moving, keep growing, keep learning It is important to mention that weighted frequency for the words removed during preprocessing (stop words, punctuation, digits etc.) will be zero and therefore is not required to be added, as mentioned below: SentenceĮase is a greater threat to progress than hardship The final step is to plug the weighted frequency in place of the corresponding words in original sentences and finding their sum. Replace Words by Weighted Frequency in Original Sentences Since the word "keep" has the highest frequency of 5, therefore the weighted frequency of all the words have been calculated by dividing their number of occurances by 5. The following table contains the weighted frequencies for each word: Word We can find the weighted frequency of each word by dividing its frequency by the frequency of the most occurring word. Next we need to find the weighted frequency of occurrences of all the words. After tokenizing the sentences, we get list of following words: ['keep', We need to tokenize all the sentences to get all the words that exist in the sentences. After preprocessing, we get the following sentences: So, keep moving, keep growing, keep learningĪfter converting paragraph to sentences, we need to remove all the special characters, stop words and numbers from all the sentences.Ease is a greater threat to progress than hardship.So if we split the paragraph under discussion into sentences, we get the following sentences: The most common way of converting paragraphs to sentences is to split the paragraph whenever a period is encountered. We first need to convert the whole paragraph into sentences. To summarize the above paragraph using NLP-based techniques we need to follow a set of steps, which will be described in the following sections. We can see from the paragraph above that he is basically motivating others to work hard and never give up. ![]() The following is a paragraph from one of the famous speeches by Denzel Washington at the 48th NAACP Image Awards: I will explain the steps involved in text summarization using NLP techniques with the help of an example. Rather we will simply use Python's NLTK library for summarizing Wikipedia articles. We will not use any machine learning library in this article. In this article, we will see a simple NLP-based technique for text summarization. ![]() There are two main types of techniques used for text summarization: NLP-based techniques and deep learning-based techniques. Text summarization is a subdomain of Natural Language Processing (NLP) that deals with extracting summaries from huge chunks of texts. ![]() In this article, we will see how we can use automatic text summarization techniques to summarize text data. The data can be in any form such as audio, video, images, and text. The most efficient way to get access to the most important parts of the data, without having to sift through redundant and insignificant data, is to summarize the data in a way that it contains non-redundant and useful information only. Furthermore, a large portion of this data is either redundant or doesn't contain much useful information. It is impossible for a user to get insights from such huge volumes of data. This is an unbelievably huge amount of data. As I write this article, 1,907,223,370 websites are active on the internet and 2,722,460 emails are being sent per second.
