• postprocess (Optional[Component], optional): Component executed after predictor. If equals to None, default component will be used. Defaults to None. Default component: TokenSearcherTextCleanerPostprocessor

• input_class (Type[Input], optional): Class for input validation. Defaults to TokenSearcherTextCleanerInput.

• output_class (Type[NEROutputType], optional): Class for output validation. Defaults to TokenSearcherTextCleanerOutput.

• name (Optional[str], optional): Name for identification. If equals to None, class name will be used. Defaults to None.
