# Named Entity Recognition

> **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 Named Entity Recognition](https://docs.catalyst.zoho.com/en/zia-services/help/text-analytics/introduction) is a part of Text Analytics that processes textual content to extract key words and group them into various categorizes. For example, it can determine a word in a text to be the name of an organization, the name of a person, or a date, and add it to the appropriate category accordingly. [Refer here](https://docs.catalyst.zoho.com/en/zia-services/help/text-analytics/introduction) for a list of all categories recognized by NER.

You can pass a block of text as the input of up to **1500 characters** in a single request. The text is passed to `getNERPrediction()`.

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.getNERPrediction([
  '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
console.log(result);
```

#### Exmaple of Expected Response

A sample response that you will receive is shown below. The response returns an array of all the entities recognized in the text, and a tag indicating the category they belong to. It will also contain the confidence score of each categorization in percentage values, to showcase its accuracy. The response also returns the location of the entity in the text through its start index and end index.

```javascript
{
  "ner": {
    "general_entities": [
      { "start_index": 0, "confidence_score": 98, "end_index": 16, "ner_tag": "Organization", "token": "Zoho Corporation" },
      { "start_index": 24, "confidence_score": 99, "end_index": 30, "ner_tag": "Miscellaneous", "token": "Indian" },
      { "start_index": 122, "confidence_score": 90, "end_index": 139, "ner_tag": "Miscellaneous", "token": "Zoho Office Suite" },
      { "start_index": 168, "confidence_score": 99, "end_index": 181, "ner_tag": "Person", "token": "Sridhar Vembu" },
      { "start_index": 186, "confidence_score": 96, "end_index": 197, "ner_tag": "Person", "token": "Tony Thomas" },
      { "start_index": 220, "confidence_score": 100, "end_index": 225, "ner_tag": "Number", "token": "seven" },
      { "start_index": 268, "confidence_score": 99, "end_index": 275, "ner_tag": "City", "token": "Chennai" },
      { "start_index": 277, "confidence_score": 98, "end_index": 282, "ner_tag": "Country", "token": "India" },
      { "start_index": 314, "confidence_score": 99, "end_index": 324, "ner_tag": "City", "token": "Pleasanton" },
      { "start_index": 326, "confidence_score": 91, "end_index": 336, "ner_tag": "State", "token": "California" }
    ]
  }
}
