Field Detail

PARAM_LANGUAGE

public static final String PARAM_LANGUAGE

Use this language instead of the document language to resolve the model.

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_EXECUTABLE_PATH

public static final String PARAM_EXECUTABLE_PATH

Use this TreeTagger executable instead of trying to locate the executable automatically.

See Also:

Constant Field Values

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_CHUNK_MAPPING_LOCATION

public static final String PARAM_CHUNK_MAPPING_LOCATION

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

See Also:

Constant Field Values

chunkMappingLocation

protected String chunkMappingLocation

PARAM_INTERN_TAGS

public static final String PARAM_INTERN_TAGS

Use the String.intern() method on tags. This is usually a good idea to avoid spaming the heap with thousands of strings representing only a few different tags. Default: true

See Also:

Constant Field Values

PARAM_PRINT_TAGSET

public static final String PARAM_PRINT_TAGSET

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

See Also:

Constant Field Values

printTagSet

protected boolean printTagSet

PARAM_PERFORMANCE_MODE

public static final String PARAM_PERFORMANCE_MODE

TT4J setting: Disable some sanity checks, e.g. whether tokens contain line breaks (which is not allowed). Turning this on will increase your performance, but the wrapper may throw exceptions if illegal data is provided.

See Also:

Constant Field Values

PARAM_FLUSH_SEQUENCE

public static final String PARAM_FLUSH_SEQUENCE

A sequence to flush the internal TreeTagger buffer and to force it to output the rest of the completed analysis. This is typically just a sequence of like 5-10 full stops (".") separated by new line characters. However, some models may require a different flush sequence, e.g. a short sentence in the respective language. For chunker models, mind that the sentence must also be POS tagged, e.g. Nous-PRO:PER\n....
