Method Detail

getValueToUriMap

protected Map<String,Set<String>> getValueToUriMap(ACache cache,
                                                   String property)

Helper method, re-factored from common setup code of Mappers.

Parameters:

cache, - Input cache

property, - Input linking property

Returns:

reversed Map from literal values to resource uris for a specified property

getUriToUriMapping

protected AMapping getUriToUriMapping(Map<String,Map<String,Double>> valueMap,
                                      Map<String,Set<String>> sourceValueToUriMap,
                                      Map<String,Set<String>> targetValueToUriMap,
                                      boolean swapped)

Helper method, re-factored from common return code blocks.

Parameters:

valueMap - Mapping from values to values with similarity score

sourceValueToUriMap - ValueToUriMap constructed from a source cache

targetValueToUriMap - ValueToUriMap constructed from a target cache

swapped - True if source and target have been swapped in the valueMap

Returns:

Mapping from source resource uri to target resource uri

getUriToUriMapping

protected AMapping getUriToUriMapping(Map<String,Map<String,Double>> valueMap,
                                      Map<String,Set<String>> sourceValueToUriMap,
                                      Map<String,Set<String>> targetValueToUriMap)
