TextClassifier class

Performs Natural Language classification.

Signature:

export declare class TextClassifier extends TaskRunner 

Methods

Method Modifiers Description
createFromOptions(wasmFileset, textClassifierOptions) static Initializes the Wasm runtime and creates a new text classifier from the provided options.
createFromModelBuffer(wasmFileset, modelAssetBuffer) static Initializes the Wasm runtime and creates a new text classifier based on the provided model asset buffer.
createFromModelPath(wasmFileset, modelAssetPath) static Initializes the Wasm runtime and creates a new text classifier based on the path to the model asset.
setOptions(options) Sets new options for the text classifier. Calling setOptions() with a subset of options only affects those options. You can reset an option back to its default value by explicitly setting it to undefined.
classify(text) Performs Natural Language classification on the provided text and waits synchronously for the response.

TextClassifier.createFromOptions()

Initializes the Wasm runtime and creates a new text classifier from the provided options.

Signature:

static createFromOptions(wasmFileset: WasmFileset, textClassifierOptions: TextClassifierOptions): Promise<TextClassifier>;

Parameters

Parameter Type Description
wasmFileset WasmFileset A configuration object that provides the location of the Wasm binary and its loader.
textClassifierOptions TextClassifierOptions The options for the text classifier. Note that either a path to the TFLite model or the model itself needs to be provided (via baseOptions).

Returns:

Promise<TextClassifier>

TextClassifier.createFromModelBuffer()

Initializes the Wasm runtime and creates a new text classifier based on the provided model asset buffer.

Signature:

static createFromModelBuffer(wasmFileset: WasmFileset, modelAssetBuffer: Uint8Array | ReadableStreamDefaultReader): Promise<TextClassifier>;

Parameters

Parameter Type Description
wasmFileset WasmFileset A configuration object that provides the location of the Wasm binary and its loader.
modelAssetBuffer Uint8Array | ReadableStreamDefaultReader An array or a stream containing a binary representation of the model.

Returns:

Promise<TextClassifier>

TextClassifier.createFromModelPath()

Initializes the Wasm runtime and creates a new text classifier based on the path to the model asset.

Signature:

static createFromModelPath(wasmFileset: WasmFileset, modelAssetPath: string): Promise<TextClassifier>;

Parameters

Parameter Type Description
wasmFileset WasmFileset A configuration object that provides the location of the Wasm binary and its loader.
modelAssetPath string The path to the model asset.

Returns:

Promise<TextClassifier>

TextClassifier.setOptions()

Sets new options for the text classifier. Calling setOptions() with a subset of options only affects those options. You can reset an option back to its default value by explicitly setting it to undefined.

Signature:

setOptions(options: TextClassifierOptions): Promise<void>;

Parameters

Parameter Type Description
options TextClassifierOptions The options for the text classifier.

Returns:

Promise<void>

TextClassifier.classify()

Performs Natural Language classification on the provided text and waits synchronously for the response.

Signature:

classify(text: string): TextClassifierResult;

Parameters

Parameter Type Description
text string The text to process.

Returns:

TextClassifierResult
