Description copied from interface: WordSenseDisambiguator

Disambiguate a named entity.

Specified by:

disambiguate in interface WordSenseDisambiguator

Parameters:

sentenceConcepts - named entities from the document, represented as list of sets of concept ids

index - index of target named entity to disambiguate

contextConcepts - context concepts, e.g. from title

windowSize - number of named entities on either side of target to use for disambiguation

metric - metric to use

scoreMap - optional to get the scores assigned to each concept

weighted - to weight context concepts by frequency

Returns:

highest scoring concept, or null if none of the target concepts are in the concept graph, or if all the target concepts have the same score
