Method Detail

getPOSTagger

Tagger getPOSTagger()

Gets the part of speech tagger used for the term extractor

Returns:

the part of speech tagger used

getOntology

Ontology getOntology()

Gets the ontology used for the term extractor.

Returns:

the ontology used

setCoordinatingCheckOption

void setCoordinatingCheckOption(boolean option)

Set the option of checking the coordinating terms

Parameters:

option - the option of checking the coordinating terms

getCoordinatingCheckOption

boolean getCoordinatingCheckOption()

Gets the option of checking the coordinating terms

Returns:

true if the extractor checks the coordinating terms

setAbbreviationOption

void setAbbreviationOption(boolean option)

Sets the option of checking terms in abbreviation.

Parameters:

option - the option of checking terms in abbreviation.

getAbbreviationOption

boolean getAbbreviationOption()

Gets the option of checking terms in abbreviation.

Returns:

true if the extractor checks terms in abbreviation.

setAttributeCheckOption

void setAttributeCheckOption(boolean option)

getAttributeCheckOption

boolean getAttributeCheckOption()

enableAttributeCheckOption

boolean enableAttributeCheckOption(AttributeChecker checker)

getSemanticCheckOption

boolean getSemanticCheckOption()

Gets the option of checking the semantic type of the extracted term

Returns:

true if the extractor checks the semantic type of the term

setSemanticCheckOption

void setSemanticCheckOption(boolean option)

Sets the option of checking the semantic type of the extracted term

Parameters:

option - the option of checking the semantic type of the extracted term

getCoordinatingTermPredictOption

boolean getCoordinatingTermPredictOption()

Gets the option of predicting terms according to coordinating relationship. Predicated terms have no entry id.

Returns:

true if the extractor predicts terms according to coordinating relationship.

setCoordinatingTermPredictOption

void setCoordinatingTermPredictOption(boolean option)

Sets the option of predicting terms according to coordinating relationship.

Parameters:

option - the option of predicting terms according to coordinating relationship.

getCompoundTermPredictOption

boolean getCompoundTermPredictOption()

Gets the option of predicting compound terms. Predicted terms have no entry id. Componenets of predicted compound terms will be removed from the extracted term list.

Returns:

true if the extractor predicts compound terms

setCompoundTermPredictOption

void setCompoundTermPredictOption(boolean option)

Sets the option of predicting compound terms.

Parameters:

option - the option of predicting compound terms.

enableCompoundTermPredictOption

boolean enableCompoundTermPredictOption(String suffixFilename)

Enable the option compound term prediction.

Parameters:

suffixFilename - the name of the file containing a list of suffix for compound terms

Returns:

true if no error occurs
