How to paraphrase text using ML algorithms in Python?

The paraphrasing technique can be of great help if you want to improve the quality of your text and make it unique. It is used in almost all types of writing, like blogs, texts, stories, etc.

Certainly, I can add the keyword “ML solutions” to your text:

“In various forms of writing, there are various methods of paraphrasing text. In this article we will explore the technique of using Machine Learning (ML) Algorithms in Python to achieve paraphrasing. ML solutions can greatly facilitate this process, making it more efficient and accurate.

It’s a bit complicated process, but we have tried to explain it in the simplest way by providing a step by step guide. So, without further ado, let’s get started.

Before doing so, let’s understand what Machine Learning solutions are and how they work in Python, one of the most used programming languages ​​in the world.

How does machine learning work in Python?

Machine learning involves teaching a computer to learn new things independently. This helps the technology improve better while performing useful functionality for us.

In Python, different libraries and frameworks are used to perform machine learning. The process, however, includes various stages. From collecting data, learning models, and executing commanded tasks, machine learning allows many tasks to be performed smoothly.

One of these tasks is paraphrasing. You can perform paraphrasing manually by simply replacing words with synonyms and changing their structure.

If you find this too difficult, you can simply use an online service paraphrase tool to do this, which also detects words that need to be replaced using ML and NLP.

But for now, we’re going to make it using a different method. Let’s get started.

Paraphrase text using ML algorithms in Python:

You need to obtain the required transformers to paraphrase text using a machine learning algorithm in Python.

Transformers are programs used in NLP (Natural language processing) to perform various tasks on texts. These transformers help the computer understand and work on human language.

The transformer we are going to use in this process is the Pegasus transformer. We will also use Google Collaboration to complete this process.

So, let’s get started and try to paraphrase a text with Python ML algorithms.

Step 1:

The transformer we are going to use in this process is the Pegasus transformer. We will also use Google Collaboration to complete this process.

This will install all the libraries required for text paraphrasing.

After this step, you need to import the date of these libraries using the following code:

2nd step:

In the second step, we will launch the Pegasus transformer and add codes to start the process of paraphrasing the text. It’s quite simple. You have to “PegasusForConditionalGeneration.” This code is designed for text generation and will help us do that.

You need to write the following code to bring the required results.

Here’s how Google Collaboration answered it.

Step 3:

The third step in trying to rephrase text using machine learning algorithms in Python is to make it capable of providing us with multiple paraphrased versions of the text.

Once applied, the program will provide us with several alternative versions of the text, which can help us select the one that suits you best.

To perform this task, specific instructions must be given to the program. To do this, you have to succeed”num_return_sequences” to model “model.generate()»

Another thing you can/should do is make the program able to search multiple synonyms for a word and choose the most relevant and appropriate one. This part can help maintain the true idea of ​​the text.

Let’s start the process.

Create a following code in Google Collaboration or whatever editor you use and paste it, add this:

In the code above, “num_10” is given to tell the program to provide us with 10 different paraphrased versions of the text we provided.

You will get the result by following these steps to paraphrase a sentence.

As you can see in the image above, the paraphrased sentences provided are quite accurate. Likewise, you can paraphrase text of any length and get accurate results.

Paraphrasing a piece of text in this way takes a lot of time. You can do it manually by yourself. Otherwise, many tools are also available. But there is one thing about paraphrasing text using Python. It allows you to learn how the language is processed in these tools.

It’s about learning how the tools work and providing you with rewritten content.

Besides the Pegasus transformer, other transformers can be used to paraphrase text using machine learning algorithms. These transformers include:

  • Transformer T5: These transformers are often used for a wide range of NLP tasks and whenever a multitasking transformer is required.
  • Parrot paraphraser: These transformers are specially designed for paraphrasing purposes. Therefore, they can be a better choice for generating high-quality and appropriate alternative versions of texts.

Now let’s see how paraphrasing tools (those that automatically restructure content for you) use these algorithms.

How do paraphrasing tools use ML algorithms?

The machine learning algorithms that we have discussed in detail in the steps above come pre-installed in the paraphrasing tools. These tools are designed based on these algorithms to help you automate the paraphrasing process.

The only major difference between paraphrasing using Python on your own and using a paraphrasing tool to get the job done is time consumption and convenience.

This means that writing codes to paraphrase text is a long and difficult task.

Paraphrasing tools use exact (or similar) algorithms to provide the same results.

The developers of these tools make sure to populate them with enough databases to provide you with multiple paraphrased versions to improve the quality of the paraphrasing. This makes it the ideal option for paraphrasing instead of using Python coding.


Learning to paraphrase can be a great skill. By executing it precisely, you can make your content unique to avoid plagiarism and bring it the required tone and quality.

Replacing words with their synonyms, which is the basic idea of ​​paraphrasing, can allow you to generate several alternative versions of a text. These different versions have the same meaning as the original and can be used for various purposes.

There are different methods for paraphrasing content. The one we have discussed in this blog includes ML Algorithms in Python. Paraphrasing tools that automate content rephrasing and restructuring for you work by similar rules.

These tools use these Machine Learning algorithms to provide you with paraphrased text. These tools have already fed a huge amount of data, which allows them to offer you different versions of the same text. In the above information, you can find details about how to paraphrase text using ML algorithms in Python and the working mechanism of a paraphrasing tool.
