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

Example 1 with EntityType

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

the class AWSComprehendService method fetchEntities.

private List<Entity> fetchEntities(String text, LanguageType language) throws PredictionsException {
    // Skip if configuration specifies NOT entities
    if (!isResourceConfigured(InterpretTextConfiguration.InterpretType.ENTITIES)) {
        return null;
    }
    DetectEntitiesRequest request = new DetectEntitiesRequest().withText(text).withLanguageCode(language.getLanguageCode());
    // Detect entities from given text via AWS Comprehend
    final DetectEntitiesResult result;
    try {
        result = comprehend.detectEntities(request);
    } catch (AmazonClientException serviceException) {
        throw new PredictionsException("AWS Comprehend encountered an error while detecting entities.", serviceException, "See attached service exception for more details.");
    }
    // Convert AWS Comprehend's detection result to Amplify-compatible format
    List<Entity> entities = new ArrayList<>();
    for (com.amazonaws.services.comprehend.model.Entity comprehendEntity : result.getEntities()) {
        EntityType entityType = EntityTypeAdapter.fromComprehend(comprehendEntity.getType());
        Entity amplifyEntity = Entity.builder().value(entityType).confidence(comprehendEntity.getScore() * PERCENT).targetText(comprehendEntity.getText()).startIndex(comprehendEntity.getBeginOffset()).build();
        entities.add(amplifyEntity);
    }
    return entities;
}

Example 2 with EntityType

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

the class AWSPredictionsInterpretTest method testEntityDetection.

/**
 * Assert that entities are detected.
 * @throws Exception if prediction fails
 */
@Test
public void testEntityDetection() throws Exception {
    final String sampleText = "Toto, I've a feeling we're not in Kansas anymore.";
    // Interpret sample text and assert non-null result
    InterpretResult result = predictions.interpret(sampleText);
    assertNotNull(result);
    // Assert entities detection
    List<Entity> actual = result.getEntities();
    List<EntityType> expected = Arrays.asList(// Toto (it's a dog, but close enough)
    EntityType.PERSON, // Kansas
    EntityType.LOCATION);
    FeatureAssert.assertMatches(expected, actual);
