All Implemented Interfaces:

org.apache.uima.analysis_component.AnalysisComponent

public class LangDetectLanguageIdentifier
extends org.apache.uima.fit.component.JCasAnnotator_ImplBase

Langdetect language identifier based on character n-grams. Due to the way LangDetect is implemented, this component does not support being instantiated multiple times with different model locations. Only a single model location can be active at a time over all instances of this component.

Field Detail

PARAM_VARIANT

public static final String PARAM_VARIANT

Variant of a model the model. Used to address a specific model if here are multiple models for one language.

Constant Field Values

variant

protected String variant

PARAM_MODEL_ARTIFACT_URI

public static final String PARAM_MODEL_ARTIFACT_URI

URI of the model artifact. This can be used to override the default model resolving mechanism and directly address a particular model.

The URI format is mvn:${groupId}:${artifactId}:${version}. Remember to set the variant parameter to match the artifact. If the artifact contains the model in a non-default location, you also have to specify the model location parameter, e.g. classpath:/model/path/in/artifact/model.bin.

Constant Field Values

modelArtifactUri

protected String modelArtifactUri

PARAM_MODEL_LOCATION

public static final String PARAM_MODEL_LOCATION

Location from which the model is read.

See Also:

Constant Field Values

modelLocation

protected String modelLocation

PARAM_SEED

public static final String PARAM_SEED

The random seed.
