Field Detail

PARAM_LANGUAGE

public static final String PARAM_LANGUAGE

Use this language instead of the language set in the CAS to locate the model.

See Also:

Constant Field Values

language

protected String language

PARAM_VARIANT

public static final String PARAM_VARIANT

Override the default variant used to locate the model.

See Also:

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.

See Also:

Constant Field Values

modelArtifactUri

protected String modelArtifactUri

PARAM_MODEL_LOCATION

public static final String PARAM_MODEL_LOCATION

Load the model from this location instead of locating the model automatically.

See Also:

Constant Field Values

modelLocation

protected String modelLocation

PARAM_MAPPING_ENABLED

public static final String PARAM_MAPPING_ENABLED

Enable/disable type mapping.

See Also:

Constant Field Values

mappingEnabled

protected boolean mappingEnabled

PARAM_POS_MAPPING_LOCATION

public static final String PARAM_POS_MAPPING_LOCATION

Location of the mapping file for part-of-speech tags to UIMA types.

See Also:

Constant Field Values

posMappingLocation

protected String posMappingLocation

PARAM_CONSTITUENT_MAPPING_LOCATION

public static final String PARAM_CONSTITUENT_MAPPING_LOCATION

Location of the mapping file for constituent tags to UIMA types.

See Also:

Constant Field Values

constituentMappingLocation

protected String constituentMappingLocation

PARAM_PRINT_TAGSET

public static final String PARAM_PRINT_TAGSET

Log the tag set(s) when a model is loaded.

See Also:

Constant Field Values

printTagSet

protected boolean printTagSet

PARAM_READ_POS

public static final String PARAM_READ_POS

Sets whether to use or not to use already existing POS tags from another annotator for the parsing process.

See Also:

Constant Field Values

PARAM_WRITE_POS

public static final String PARAM_WRITE_POS

Sets whether to create or not to create POS tags. The creation of constituent tags must be turned on for this to work.

See Also:

Constant Field Values

PARAM_WRITE_PENN_TREE

public static final String PARAM_WRITE_PENN_TREE

If this parameter is set to true, each sentence is annotated with a PennTree-Annotation, containing the whole parse tree in Penn Treebank style format.

See Also:

Constant Field Values

PARAM_VITERBI

public static final String PARAM_VITERBI

Compute Viterbi derivation instead of max-rule tree.

See Also:
