Method Detail

setSplit

public void setSplit(String split)

getMapping

public AMapping getMapping(Map<String,Set<String>> sourceMap,
                           Map<String,Set<String>> targetMap,
                           double threshold)

Parameters:

sourceMap - Texts to compare with target

targetMap - Texts to compare with source

threshold - is the minimum similarity of the results

Returns:

all results of source compare with target together with the similarity of them

getMapping

public AMapping getMapping(ACache source,
                           ACache target,
                           String sourceVar,
                           String targetVar,
                           String expression,
                           double threshold)

Description copied from interface: IMapper

Returns a mapping given a source, a target knowledge base and a link specification.

Parameters:

source - source cache

target - target cache

sourceVar - source property variable

targetVar - size property variable

expression - metric expression of link specification

threshold - threshold of link specification

Returns:

a mapping, the resulting mapping

getName

Description copied from interface: IMapper

Returns the name of the mapper.

Returns:

Mapper name as a string
