## What is [Topic Extraction](http://www.edenai.co/feature/topic-extraction?referral=best-topic-extraction-2023)?

Topic Extractoion API allows users to extract topics or key themes from a given text or document. These APIs are designed to analyze the content and identify the main subjects or topics discussed within the text. By leveraging natural language processing (NLP) techniques, such as machine learning algorithms and linguistic analysis, the API can identify and extract relevant topics from various types of textual data, including articles, blog posts, social media updates, customer reviews, and more.

The extracted topics can then be used for various purposes, such as organizing and categorizing large volumes of text, generating tags for content recommendation systems, sentiment analysis, trend detection, content filtering, etc.

### **2. Let’s identify topics in your texts**

Once you have imported packages on Python and got your API key, you will be able to identify topics in text content.  You can access the list of Topic Extraction [engines](https://docs.edenai.co/reference/text_topic_extraction_create?referral=topic-extraction-python) available on Eden AI to help you choose the provider that best suits your project and needs.

‍

Here is the Python script you need to write in your notebook:

For example, we called two different Topic Extraction engines. Eden AI API will then return in its JSON response results of those providers.

‍

Once the request is done, you will be able to get the result with this print:
