Class ALDecider

java.lang.Object

org.aksw.limes.core.ml.algorithm.eagle.core.ALDecider

public class ALDecider
extends Object

Class to get the most controversy matches out of n Mappings. The most controversy matches are those contained in close to n/2 Mappings and vice versa. This functionality is required by the Active Learning approach of the genetics package.

NOTE: Functionality requires de.uni_leipzig.simba.data.Triple.class to implement the Comparable interface and overrides hashCode() function such that a Triple t1 is considered to equals another Triple t2 iff both source and target URIs are equal.

Method Detail

main

public static void main(String[] args)

getControversyMatches

public HashMap<ALDecider.Triple,Integer> getControversyMatches(List<AMapping> mapList)

Method returns the controversy matches of the given Mapping. This is just a HashMap, whereas the keys are the Triples and the values the number of Mappings holding this Triple.

Parameters:

mapList - A List of all Mappings to process.

Returns:

HashMap a map of Triples (matches) and the number of Mappings holding them.

getControversyCandidates

public List<ALDecider.Triple> getControversyCandidates(List<AMapping> mapList,
                                                       int n)

Function to get the n most controversy matching candidates of the given mappings. The most controversy once are those, who are only in half of the given mappings.

Parameters:

mapList - List of Mappings.

n - Controls how many candidates should be retrieved.

Returns:

getControversyCandidates

public List<ALDecider.Triple> getControversyCandidates(List<AMapping> mapList)

Parameters:

mapList -

Returns:

tripleList with informative value

setKnown

public void setKnown(AMapping m)

To set already retrieved instances. For example those provided at start up.

Parameters:

m - Mapping of already asked URIs of source and target.
