All Implemented Interfaces:

org.apache.uima.analysis_component.AnalysisComponent

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

OpenNLP parser. The parser ignores existing POS tags and internally creates new ones. However, these tags are only added as annotation if explicitly requested via PARAM_WRITE_POS.

Fields

Modifier and Type	Field and Description
protected String	constituentMappingLocation
protected String	language
protected String	modelLocation
static String	PARAM_CONSTITUENT_MAPPING_LOCATION Location of the mapping file for constituent tags to UIMA types.
static String	PARAM_INTERN_TAGS Use the String.intern() method on tags.
static String	PARAM_LANGUAGE Use this language instead of the document language to resolve the model.
static String	PARAM_MODEL_LOCATION Load the model from this location instead of locating the model automatically.
static String	PARAM_POS_MAPPING_LOCATION Load the part-of-speech tag to UIMA type mapping from this location instead of locating the mapping automatically.
static String	PARAM_PRINT_TAGSET Log the tag set(s) when a model is loaded.
static String	PARAM_VARIANT Override the default variant used to locate the model.
static 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.
static String	PARAM_WRITE_POS Sets whether to create or not to create POS tags.

Field Detail

PARAM_LANGUAGE

public static final String PARAM_LANGUAGE

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

Default: true

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.

Default: false

See Also:

Constant Field Values
