Method Detail

getQueryNode

public com.hp.hpl.jena.rdf.model.RDFNode getQueryNode()

Specified by:

getQueryNode in interface NodeMatchingResult

Returns:

RDFNode from a query graph

getResNode

public com.hp.hpl.jena.rdf.model.RDFNode getResNode()

Specified by:

getResNode in interface NodeMatchingResult

Returns:

RDFNode resource graph

getLabel

public java.lang.String getLabel()

Specified by:

getLabel in interface NodeMatchingResult

Returns:

node label specified in a matching description.

getSimilarity

public float getSimilarity()

Specified by:

getSimilarity in interface NodeMatchingResult

Returns:

similarity value of both nodes. If the node is a resource having properties this similarity value includes the similarity of the nodes and the similarities of their properties.

getWeight

public float getWeight()

Specified by:

getWeight in interface NodeMatchingResult

Returns:

weight which represents the importance of this node among other nodes in this particular cluster. The weight is a float number [0..1]. The sum of all node weights inside each cluster equals 1.

isReversed

public boolean isReversed()

Specified by:

isReversed in interface NodeMatchingResult

Returns:

true if the matching has been reversed. (=> resource and query node have been switched at similarity calculation)

getPropertyMatchingResultList

public java.util.List getPropertyMatchingResultList()

Specified by:

getPropertyMatchingResultList in interface NodeMatchingResult

Returns:

List of objects implementing the PropertyMatchingResult interface. Each of this objects holds information about the matching of a certain property of a node from a query graph with a coersponding property of a coresponding node from a resource graph. The list returned does not contain all properties of the node, but only those of them which have been specified in the matching description and thus considered by the matching engine. If the list returned is empty, is means that this node similarity is merely based on the node similarity itself without considering any properties.
