Examples with Syntax com.amplifyframework.predictions.models.Syntax used on opensource projects

Example 1 with Syntax

use of com.amplifyframework.predictions.models.Syntax in project amplify-android by aws-amplify.

the class AWSPredictionsInterpretTest method testSyntaxDetection.

/**
 * Assert that interpret correctly labels syntax.
 * @throws Exception if prediction fails
 */
@Test
public void testSyntaxDetection() throws Exception {
    final String sampleText = "I am inevitable.";
    // Interpret sample text and assert non-null result
    InterpretResult result = predictions.interpret(sampleText);
    assertNotNull(result);
    // Assert syntax detection
    List<Syntax> actual = result.getSyntax();
    List<SpeechType> expected = Arrays.asList(// I
    SpeechType.PRONOUN, // am
    SpeechType.VERB, // inevitable
    SpeechType.ADJECTIVE, // .
    SpeechType.PUNCTUATION);
    FeatureAssert.assertMatches(expected, actual);
}

Example 2 with Syntax

use of com.amplifyframework.predictions.models.Syntax in project amplify-android by aws-amplify.

the class AWSComprehendService method comprehend.

void comprehend(@NonNull String text, @NonNull Consumer<InterpretResult> onSuccess, @NonNull Consumer<PredictionsException> onError) {
    try {
        // First obtain the dominant language to begin analysis
        final Language dominantLanguage = fetchPredominantLanguage(text);

}

Example 3 with Syntax

use of com.amplifyframework.predictions.models.Syntax in project amplify-android by aws-amplify.

the class AWSComprehendService method fetchSyntax.
