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_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_POS_MAPPING_LOCATION

public static final String PARAM_POS_MAPPING_LOCATION

Load the part-of-speech tag to UIMA type mapping from this location instead of locating the mapping automatically.

See Also:

Constant Field Values

posMappingLocation

protected String posMappingLocation

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_UPPERCASE_TAGS

public static final String PARAM_UPPERCASE_TAGS

Lingpipe models tend to be trained on lower-case tags, but our POS mappings use uppercase.

See Also:

Constant Field Values

uppercaseTags

protected boolean uppercaseTags
