# Keyword Extraction

> **Note:** Ensure you have installed the [required package](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/zia-services/overview/#prerequisites) to use this SDK method.

[Zia Keyword Extraction](https://docs.catalyst.zoho.com/en/zia-services/help/text-analytics/introduction) is a part of *Text Analytics* that processes textual content and extracts the highlights of the text. The extracted terms are grouped into two categories: `Keywords` and `Keyphrases`. These highlights deliver a concise summary of the text and provide an abstraction of the whole text.

You can pass a block of text as the input of up to **1500 characters** in a single request. The text is passed to `getKeywordExtraction()`. The keywords and keyphrases are then fetched as individual lists.

The `zia` reference used in the code snippets below is the [component instance](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/zia-services/get-zia-instance/) created to perform these operations. The promise returned here is resolved to a JSON object.

```javascript
const result = await zia.getKeywordExtraction(['Zoho Corporation, is an Indian multinational technology company that makes web-based business tools. It is best known for Zoho Office Suite. The company was founded by Sridhar Vembu and Tony Thomas and has a presence in seven locations with its global headquarters in Chennai, India, and corporate headquarters in Pleasanton, California.']); //Pass the input text to be processed
console.log(result);
```

#### Example of Expected Response

A sample response that you will receive is shown below. The response contains an array of the key words, and another array of the key phrases that are extracted from the text.

```javascript
{
  "keyword_extractor": {
    "keywords": [
