Working with the API
Here is an example of sending text for interpretation such as sentiment analysis or natural language characteristics.
Amplify.Predictions.interpret( "I like to eat spaghetti", result -> Log.i("MyAmplifyApp", result.getSentiment().getValue().toString()), error -> Log.e("MyAmplifyApp", "Interpret failed", error));Amplify.Predictions.interpret("I like to eat spaghetti", { Log.i("MyAmplifyApp", "${it.sentiment?.value}") }, { Log.e("MyAmplifyApp", "Interpret failed", it) })val text = "I like to eat spaghetti"try { val result = Amplify.Predictions.interpret(text) Log.i("MyAmplifyApp", "${result.sentiment?.value}")} catch (error: PredictionsException) { Log.e("MyAmplifyApp", "Interpret failed", error)}RxAmplify.Predictions.interpret("I like to eat spaghetti") .subscribe( result -> Log.i("MyAmplifyApp", result.getSentiment().getValue().toString()), error -> Log.e("MyAmplifyApp", "Interpret failed", error) );As a result of running this code, you will see the sentiment of the text printed to the console.
