- All Implemented Interfaces:
LabelToConceptLinker
Linker able to combine different embedding approaches.
Note that the linker will not actually create a link but, instead, will return the label if it can be linked by
at least one of the given linkers.

linkToSingleConcept
Description copied from interface:LabelToConceptLinker
Queries for a concept and returns a link that represents an entity in the background knowledge source such as theSemanticWordRelationDictionary
. 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 interfaceLabelToConceptLinker
- Parameters:
labelToBeLinked
- The label which shall be linked to a single concept.- Returns:
- Concept or null if no link could be found.
-
linkLabelToTokensLeftToRight
Splits the labelToBeLinked in ngrams up to infinite size and tries to link components. This corresponds to a MAXGRAM_LEFT_TO_RIGHT_TOKENIZER or NGRAM_LEFT_TO_RIGHT_TOKENIZER OneToManyLinkingStrategy.- Parameters:
labelToBeLinked
- The label that shall be linked.- Returns:
- A set of concept URIs that were found.
-
linkToPotentiallyMultipleConcepts
Description copied from interface:LabelToConceptLinker
This method tries to linklabelToBeLinked
to one concept if possible. If it fails, it will try to link it to multiple concepts.- Specified by:
linkToPotentiallyMultipleConcepts
in interfaceLabelToConceptLinker
- Parameters:
labelToBeLinked
- The label which shall be linked.- Returns:
- One or multiple linked concepts in a set. Null if it could not fully link the label.
-
getNameOfLinker
Description copied from interface:LabelToConceptLinker
Get instance specific name of the linker.- Specified by:
getNameOfLinker
in interfaceLabelToConceptLinker
- Returns:
- Name as String.
-
setNameOfLinker
Description copied from interface:LabelToConceptLinker
Set instance specific name of the linker.- Specified by:
setNameOfLinker
in interfaceLabelToConceptLinker
- Parameters:
nameOfLinker
- Name to be set.
