Method Details

add

public void add(Correspondence cell,
 String featureName,
 String featureValue)

Add information about a cell. If the information exists already, it will be overwritten. If there has not been a data set entry, the entry will be created.

Parameters:

cell - The cell for which information shall be persisted.

featureName - The name of the feature.

featureValue - The feature value.

addAll

public void addAll(Iterable<Correspondence> cells,
 String featureName,
 String featureValue)

Add multiple cells that have the same feature value.

Parameters:

cells - Set of cells.

featureName - Feature name.

featureValue - Feature value.

addAll

public void addAll(Iterable<Correspondence> cells,
 HashMap<String,String> features)

Add multiple cells that have the same feature values.

Parameters:

cells - Set of cells.

features - Features

getMappingFeatures

public Map<String,String> getMappingFeatures(String uriOne,
 String uriTwo,
 String relation,
 double confidence)

Description copied from interface: IExplainerMapping

Gets information (features) about a mapping (represent through the parameters) from e.g. a matcher. The result is a map of feature name and corresponding value.

Specified by:

getMappingFeatures in interface IExplainerMapping

Parameters:

uriOne - the uri of the first matched entity

uriTwo - the uri of the second matched entity

relation - the relation from the mapping

confidence - the confidence of teh mapping

Returns:

a map of feature name and corresponding value.

getMappingFeatureNames

public List<String> getMappingFeatureNames()

Description copied from interface: IExplainerMapping

Get the names of the mapping features which will also appear in the result of IExplainerMapping.getMappingFeatures(String, String, String, double).

Specified by:

getMappingFeatureNames in interface IExplainerMapping

Returns:

A list of the feature names.

getMappingInformation

public HashMap<Correspondence,HashMap<String,String>> getMappingInformation()
