class AssertionMerger(classname='com.johnsnowlabs.nlp.annotators.assertion.merger.AssertionMerger', java_model=None)#

Bases: sparknlp_jsl.common.AnnotatorModelInternal, sparknlp_jsl.annotator.white_black_list_params.WhiteBlackListParams

Merges variety assertion columns coming from Assertion annotators like sparknlp_jsl.annotator.assertion.AssertionDLModel. AssertionMerger can filter, prioritize and merge assertion annotations by using proper parameters. See Also: sparknlp_jsl.annotator.WhiteBlackListParams for filtering options.

ASSERTION s	ASSERTION

Parameters:

• mergeOverlapping (bool) – Whether to merge overlapping matched assertion annotations. Default: True

• applyFilterBeforeMerge (bool) – Whether to apply filtering before merging process. If True, filtering will be applied before merging; if False, filtering will be applied after merging process. Default: False.

• blackList (list[str]) – If defined, list of entities to ignore. The rest will be processed.

• whiteList (list[str]) – If defined, list of entities to process. The rest will be ignored. Do not include IOB prefix on labels.

• caseSensitive (bool) – Determines whether the definitions of the white listed and black listed entities are case sensitive. Default: True.

• assertionsConfidence (dict[str, float]) – Pairs (assertion,confidenceThreshold) to filter assertions which have confidence lower than the confidence threshold.

• orderingFeatures (list[str]) – Specifies the ordering features to use for overlapping entities. Possible values include: ‘begin’, ‘end’, ‘length’, ‘source’, ‘confidence’. Default: [‘begin’, ‘length’, ‘source’]

• selectionStrategy (str) – Determines the strategy for selecting annotations. Annotations can be selected either sequentially based on their order (Sequential) or using a more diverse strategy (DiverseLonger). Currently, only Sequential and DiverseLonger options are available. Default: Sequential.

• defaultConfidence (float) – When the confidence value is included in the orderingFeatures and a given annotation does not have any confidence, this parameter determines the value to be used. The default value is 0.

• assertionSourcePrecedence (str) – Specifies the assertion sources to use for prioritizing overlapping annotations when the ‘source’ ordering feature is utilized. This parameter contains a comma-separated list of assertion sources that drive the prioritization. Annotations will be prioritized based on the order of the given string.

• sortByBegin (bool) – Whether to sort the annotations by begin at the end of the merge and filter process. Default: False.

clear(param)#

Clears a param from the param map if it has been explicitly set.

copy(extra=None)#

Creates a copy of this instance with the same uid and some extra params. This implementation first calls Params.copy and then make a copy of the companion Java pipeline component with extra params. So both the Python wrapper and the Java pipeline component get copied.

Parameters:

extra (dict, optional) – Extra parameters to copy to the new instance

Returns:

Copy of this instance

Return type:

JavaParams

explainParam(param)#

Explains a single param and returns its name, doc, and optional default value and user-supplied value in a string.

explainParams()#

Returns the documentation of all params with their optionally default values and user-supplied values.

extractParamMap(extra=None)#

Extracts the embedded default param values and user-supplied values, and then merges them with extra values from input into a flat param map, where the latter value is used if there exist conflicts, i.e., with ordering: default param values < user-supplied values < extra.

Parameters:

extra (dict, optional) – extra param values

Returns:

merged param map

Return type:

dict

getInputCols()#

Gets current column names of input annotations.

getLazyAnnotator()#

Gets whether Annotator should be evaluated lazily in a RecursivePipeline.

getOrDefault(param)#

Gets the value of a param in the user-supplied param map or its default value. Raises an error if neither is set.

getOutputCol()#

Gets output column name of annotations.

getParam(paramName)#

Gets a param by its name.

getParamValue(paramName)#

Gets the value of a parameter.

Parameters:

paramName (str) – Name of the parameter

hasDefault(param)#

Checks whether a param has a default value.

hasParam(paramName)#

Tests whether this instance contains a param with a given (string) name.

inputColsValidation(value)#

isDefined(param)#

Checks whether a param is explicitly set by user or has a default value.

isSet(param)#

Checks whether a param is explicitly set by user.

classmethod load(path)#

Reads an ML instance from the input path, a shortcut of read().load(path).

classmethod read()#

Returns an MLReader instance for this class.

save(path)#

Save this ML instance to the given path, a shortcut of ‘write().save(path)’.

set(param, value)#

Sets a parameter in the embedded param map.

setApplyFilterBeforeMerge(value)#

Sets whether to apply filtering before merging process. If True, filtering will be applied before merging; if False, filtering will be applied after merging process. Default: False.

Parameters:

value (bool) – Whether to apply filtering before merging process.

setAssertionSourcePrecedence(value)#

Sets Specifies the assertion sources to use for prioritizing overlapping annotations when the ‘source’ ordering feature is utilized. This parameter contains a comma-separated list of assertion sources that drive the prioritization. Annotations will be prioritized based on the order of the given string.

Parameters:

value (str) – Specifies the assertion sources to use for prioritizing overlapping annotations when the ‘source’ ordering feature is utilized.

setAssertionsConfidence(value: dict)#

Sets Pairs (assertion,confidenceThreshold) to filter assertions which have confidence lower than the confidence threshold.

Parameters:

value (dict[str, float]) – Pairs (assertion,confidenceThreshold) to filter assertions which have confidence lower than the confidence threshold.

setBlackList(value)#

Sets If defined, list of entities to ignore. The rest will be processed. Do not include IOB prefix on labels

Parameters:

value (List[str]) – If defined, list of entities to ignore. The rest will be processed. Do not include IOB prefix on labels

setCaseSensitive(value)#

Determines whether the definitions of the white listed and black listed entities are case sensitive or not.

Parameters:

value (bool) – Whether white listed and black listed entities are case sensitive or not. Default: True.

setDefaultConfidence(value)#

Sets When the confidence value is included in the orderingFeatures and a given annotation does not have any confidence, this parameter determines the value to be used.

Parameters:
