# TextClassifierNode

> Text classifier node for content classification and topic detection. Analyzes text input and classifies it into predefined categories using ML models. Returns classification results with confidence scores. You can either use a pre-configured text classifier component that could be reused across multiple nodes or node will create a new component for you.

## Input

**Type:** `String`

The data type that TextClassifierNode accepts as input

## Output

**Type:** `GraphTypes.ClassificationResult`

The data type that TextClassifierNode outputs

## Examples

```typescript theme={"system"}
// Using component configuration
const classifierNode = new TextClassifierNode({
id: 'content-classifier',
modelWeightsPath: '/models/classifier_weights.json',
embedderComponentId: 'text_embedder_component',
supportedClasses: ['hategroup', 'selfharm', 'sexual', 'sexualminors', 'substance'],
classifierConfig: {
classes: [
{ label: 'hategroup', threshold: 0.8 },
{ label: 'selfharm', threshold: 0.9 }
]
}
});

// Using existing text classifier component
const classifierComponent = new TextClassifierComponent({
id: 'existing-classifier-component',
modelWeightsPath: '/models/classifier_weights.json',
embedderComponentId: 'text_embedder_component',
supportedClasses: ['hategroup', 'selfharm']
});
const classifierNodeWithComponent = new TextClassifierNode({
id: 'content-classifier',
textClassifierComponent: classifierComponent
});
```
