How to identify topics in text content with JavaScript?

In this tutorial, you will learn how to use Topic/Entity Extraction API in 5 minutes using JavaScript. Eden AI provides an easy and developer-friendly API that allows you to identify topics in text content.

What is Topic Extraction?

Topic extraction, also known as entity extraction or content taxonomy, utilizes natural language processing (NLP) techniques to identify the main ideas and concepts in text and group them into meaningful topics. This technology takes input text and provides a list of topics along with associated keywords or phrases, allowing users to extract meaningful insights.

This API is valuable for content management, sentiment analysis, trend analysis, and more. Notably, the Topic Extraction API offers instant usability, unlike Custom Text Classification, which necessitates a pre-existing dataset.
