Types of AI in text summarization: Extractive Vs Generative Vs Abstractive

In: Artificial Intelligence

Text summarization is a hot topic in the world of AI, and for good reason. With the amount of information available on the internet, it’s becoming increasingly difficult to sift through and find the most important points. But that’s where AI text summarization comes in! It’s like having a personal assistant who can quickly read through an article or document and give you the gist of it in just a few sentences. But not all AI text summarization methods are created equal. In this article, we’ll be diving into the different types of AI text summarization: extractive, generative, and abstractive.

Think of it like a game of rock-paper-scissors, each method has its own set of strengths and weaknesses. Extractive summarization is like rock, it’s straightforward and reliable. Generative summarization is like paper, it can wrap things up nicely. And abstractive summarization is like scissors, it can cut through the fluff and get to the heart of the matter. But which one is right for you? Stick around and find out!

Extractive text summarization AI

When it comes to AI text summarization, extractive summarization is the OG method. It’s been around for a while and is considered the most straightforward and reliable of the three. Extractive summarization using AI involves identifying the most important sentences or phrases in a text and piecing them together to create a summary. It’s like a sophisticated version of highlighting the key points in a document.

The AI algorithms used for extractive text summarization are based on natural language processing and machine learning. They analyze the text and use a variety of techniques such as frequency analysis, sentiment analysis, and named entity recognition to identify the most relevant sentences. The algorithms then extract those sentences and put them together to create a summary. This type of summarization is considered to be the most accurate and unbiased because it only includes information that is already present in the original text.

Extractive text summarization using AI is perfect for use cases where you need a quick and reliable summary of a large amount of information, such as news articles, research papers, and legal documents. It’s also great for situations where you need to ensure that the summary is as accurate as possible, such as in legal or medical contexts. Overall, Extractive text summarization AI is a powerful tool that can help you quickly get to the heart of any text.

Pluaris is a powerful AI-based text summarization tool that can help you quickly and easily create summaries of any text. One of its key features is its ability to perform extractive text summarization. This means that it can identify the most important sentences or phrases in a text and piece them together to create a summary. This is done by analyzing the text and using a variety of natural language processing and machine learning techniques such as frequency analysis, sentiment analysis, and named entity recognition.

Pluaris’s extractive text summarization capabilities can save you a significant amount of time and effort when working with large amounts of text. With just a few clicks, you can get a quick and reliable summary of any document. Additionally, the platform also allows you to customize the summary by adjusting the length and the number of sentences, and also you can choose to include or exclude specific sentences, making it the perfect tool for a wide range of use cases, from research papers to legal documents. With Pluaris, you can easily get the information you need without having to spend hours reading through an entire document.

Generative text summarization using AI

Generative text summarization AI is the newest and most advanced method of text summarization. It’s like having a personal AI writer who can create a summary for you based on the information in the original text. Here are a few key points about generative text summarization AI:

  • Creates new content: Generative AI creates new content by learning patterns in data and then using that knowledge to generate new examples that fit those patterns.
  • Generates machine-generated text: Generative AI uses statistical models to generate text that is often recognizable but not necessarily human-like.
  • Does not require contextual understanding: Generative AI does not require a deep understanding of the context or meaning of information in order to generate new content.

Overall, Generative text summarization AI is a powerful tool that can help you quickly and easily create summaries of any text, and it’s becoming more advanced and sophisticated with the advancement of NLP and deep learning technology.

Abstractive text summarization using AI

Abstractive text summarization using AI is the most advanced and powerful method of text summarization. It goes beyond simple extraction and generates new phrases and sentences that convey the most important information from the original text. Here are a few key points about abstractive text summarization using AI:

  • Summarizes information: Abstractive AI summarizes existing information by comprehending it, drawing inferences, and generating new, concise representations.
  • Generates human-like text: Abstractive AI uses deep learning models to generate human-like text that summarizes or rephrases existing information.
  • Requires contextual understanding: Abstractive AI requires a deep understanding of the context and meaning of information in order to generate accurate and relevant summaries.

Overall, abstractive text summarization using AI is the most advanced method of text summarization and it’s becoming more sophisticated with the advancement of NLP and deep learning technology. It can help you quickly and easily understand complex text and get the most important information in a shorter, more readable format.

Comparison and evaluation of the different types of AI in text summarization

Comparing and evaluating the different types of AI can be a bit tricky, as each method has its own strengths and weaknesses. But to make it simple, let’s take a look at the most important features of each method in a tabular format:

MethodDescriptionProsCons
ExtractiveExtracts the most important sentences from the original textHighly accurate fastLimited to the information present in the original text May not convey the meaning as well as other methods
GenerativeGenerates a new summary based on the information in the original textCan convey the meaning better Can handle more complex textsMay have a higher error rate and May not be as accurate as extractive
AbstractiveGenerates new phrases and sentences that convey the most important information from the original textCan convey the meaning better Can handle more complex textsMay have a higher error rate and May not be as accurate as extractive

As you can see from the table, each method has its own set of pros and cons. Extractive text summarization is highly accurate, but it’s limited to the information present in the original text. Generative and abstractive text summarization can convey the meaning better, but they may have a higher error rate.

Pluaris is one tool that uses an extractive method for text summarization. To learn more about Pluaris click here.

Conclusion

In conclusion, text summarization is an important task in Natural Language Processing, and the use of AI has made it possible to generate more accurate and efficient summaries. Extractive, generative, and abstractive are the three main types of AI in text summarization. Extractive text summarization extracts the most important sentences from the original text, while generative text summarization generates a new summary based on the information in the original text, and abstractive text summarization generates new phrases and sentences that convey the most important information from the original text. Each method has its own set of pros and cons and the best method to use depends on the complexity of the text and the desired outcome. It’s important to evaluate each method and choose the one that best meets your needs.
