Text Rank Keywords API

What is Keyword Extraction using Text Rank?

A quick introduction

TextRank is an algorithm based on PageRank, which often used in keyword extraction and text summarization.

PageRank (PR) is an algorithm used to calculate the weight for web pages. We can take all web pages as a big directed graph. In this graph, a node is a webpage. If webpage A has the link to web page B, it can be represented as a directed edge from A to B.

PageRank was used by Google to rank websites, and TextRank was born to rank different texts under the same idea.

Thanks to our endpoint, you will be able to analyze any text (the longer, the better) and extract a list of the most important keywords from the text. Sounds cool, right?

This way, you will get an overall idea of what a text is about just by looking at its keywords.
