What Exactly Is Text Summarization, and How Does It Work?

In this blog post, we’ll take a look at the process of text summarization and the many applications it has in various fields.

What is text summarization?

A written summary is the process of extracting the main points from text content. The objective is to generate a reduced version of the original text that maintains its meaning and function. This is handy for taking notes, making summaries, or shortening a text to make it simpler to read. There are several techniques for summarising material, but the most popular include identifying and extracting significant words and sentences from the original text using algorithms.

How does it work?

The text summary is the practice of producing a shorter, more concise version of a given text. The purpose is to present a summary of the key ideas without requiring the reader to read the complete document. Extraction-based and abstraction-based text summarization are the two primary forms.

Extraction-based processes To construct the summary, choose certain sentences or paragraphs from the original content. There are a number of methods that can automate this procedure, however, it may be done manually. Abstractive approaches develop new phrases that convey the original text’s meaning. In general, this is more challenging than extraction-based summarising, but it can provide a more natural-sounding summary.

Both extractive and abstractive procedures have advantages and disadvantages, therefore it is essential to select the appropriate one for the work at hand. An extractive summary is generally more effective for shorter texts, but abstractive summarization is more effective for larger ones.

Types of text summarization

There are a few different types of text summarization, and each has its own strengths and weaknesses. Here are a few of the most common methods:

1. Extractive Summarization: This is the most basic form of summarization, and involves pulling out the most important sentences from a piece of text. The advantage of this method is that it is quick and easy to do. However, the disadvantage is that it can often miss important details, and the summary may not be coherent.

2. Abstractive Summarization: This method involves creating a new summary that captures the essence of the original text. The advantage of this method is that it can provide a more comprehensive summary. However, the disadvantage is that it can be more time-consuming to do.

3. Hybrid Summarization: This method combines aspects of both extractive and abstractive summarization. The advantage of this method is that it can provide a more balanced summary. However, the disadvantage is that it can be more difficult to do than either extractive or abstractive summarization alone.

Advantages of text summarization

Text summarization has several benefits, including the capacity to reduce enormous volumes of information in a more comprehensible manner. This is especially useful when attempting to comprehend the major ideas of a lengthy text or article. Additionally, summaries can give clarity and enhance comprehension by reducing complicated ideas to their essence.

Time savings is an additional advantage of the summary. In today’s fast-paced society, we frequently lack the time to read anything in its full. A well-written summary may provide us with the necessary details without requiring us to go through unnecessary detail.

In conclusion, a text summary may be a beneficial technique for enhancing writing abilities. By learning how to recognize the most essential aspects of a text and condense them, we may become better communicators overall.

Disadvantages of text summarization

There are a number of possible drawbacks to text summarization, especially when the technique is not implemented properly. First, summaries might be significantly shorter than the original text, which can result in the omission of crucial elements and context. In addition, the summary may not adequately convey the original text’s tone or style, which might lead to misunderstandings. If the algorithm for summarising is insufficiently advanced, it may just regurgitate information without giving any actual insight or comprehension.


We examined what text summarization is and how it operates in this post. In addition, we examined the many forms of text summarization and the uses of this technique. Text summary offers a variety of possible uses, ranging from assisting students in comprehending a textbook’s key concepts to allowing busy executives to absorb content more quickly. As technology continues to advance, we can only speculate about its future applications.
