# Keyword Extraction

[Zia Keyword Extraction](https://docs.catalyst.zoho.com/en/zia-services/help/text-analytics/key-concepts/#keyword-extraction) 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.

The response contains an array of the key words, and another array of the key phrases that are extracted from the text.

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

#### Sample Code Snippet 

**Package Imports**

```java
import org.json.simple.JSONArray; 
import com.zc.component.ml.ZCKeywordExtractionData; 
import com.zc.component.ml.ZCML;
import java.io.File;

```

```java
JSONArray textArray = new JSONArray();
textArray.add("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.");
//Input text to be processed 
List listOfKeywordExtractionData = ZCML.getInstance().getKeywordExtraction(textArray);
//Text is passed 
ZCKeywordExtractionData keywordExtractionData = listOfKeywordExtractionData.get(0); 
List keywordsList = keywordExtractionData.getKeywords(); 
//To fetch the keywords 
List keyphrasesList = keywordExtractionData.getKeyphrases(); //To fetch the keyphrases

```
