Method Details

linkToSingleConcept

public String linkToSingleConcept(String labelToBeLinked)

Description copied from interface: LabelToConceptLinker

Queries for a concept and returns a link that represents an entity in the background knowledge source such as the SemanticWordRelationDictionary. Note that the link may not always be something intuitive such as a URI but may also be an artificial identifier that is understood by the corresponding background knowledge source.

Specified by:

linkToSingleConcept in interface LabelToConceptLinker

Overrides:

linkToSingleConcept in class LabelToConceptLinkerEmbeddings

Parameters:

labelToBeLinked - The label which shall be linked to a single concept.

Returns:

Concept or null if no link could be found.

getNameOfLinker

public String getNameOfLinker()

Description copied from interface: LabelToConceptLinker

Get instance specific name of the linker.

Specified by:

getNameOfLinker in interface LabelToConceptLinker

Returns:

Name as String.

setNameOfLinker

public void setNameOfLinker(String nameOfLinker)

Description copied from interface: LabelToConceptLinker

Set instance specific name of the linker.

Specified by:

setNameOfLinker in interface LabelToConceptLinker

Parameters:

nameOfLinker - Name to be set.

normalizeStatic

public static String normalizeStatic(String stringToBeNormalized)

Normalize strings. Static so that behavior can be easily controlled by unit tests.

Parameters:

stringToBeNormalized - The string that shall be normalized.

Returns:

Normalized String.

normalize

public String normalize(String stringToBeNormalized)

Description copied from class: LabelToConceptLinkerEmbeddings

Normalization

Specified by:

normalize in class LabelToConceptLinkerEmbeddings

Parameters:

stringToBeNormalized - The String that shall be normalized.

Returns:

Normalized version of the String.

getSynonymyConfidence

public double getSynonymyConfidence(String linkedConcept1,
 String linkedConcept2)

Description copied from interface: SynonymConfidenceCapability

Given two links, determine the degree of synonymy.

Specified by:

getSynonymyConfidence in interface SynonymConfidenceCapability

Parameters:

linkedConcept1 - Linked concept 1.

linkedConcept2 - Linked concept 2.

Returns:

True if synonymous, else false.

getStrongFormSynonymyConfidence

public double getStrongFormSynonymyConfidence(String linkedConcept1,
 String linkedConcept2)

Description copied from interface: SynonymConfidenceCapability

Given two links, determine the degree of synonymy.

Specified by:

getStrongFormSynonymyConfidence in interface SynonymConfidenceCapability

Parameters:

linkedConcept1 - Linked concept 1.

linkedConcept2 - Linked concept 2.

Returns:

True if synonymous, else false.
