Interface NodeMatchingResult

All Known Implementing Classes:

NodeMatchingResultImpl

public interface NodeMatchingResult

In Jena2 all property values are of type RDFNode (Resources or Literals). If the property value is a blank node, then it may have further properties which should be considered by the matching engine. In this case the method getPropertyMatchingResultList() will return a list of objects representing the matching reulst of each single property.

Method Detail

getQueryNode

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

Returns:

RDFNode from a query graph

getResNode

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

Returns:

RDFNode resource graph

getLabel

java.lang.String getLabel()

Returns:

node label specified in a matching description.

getSimilarity

float getSimilarity()

Returns:

the 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

float getWeight()

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

boolean isReversed()

Returns:

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

getPropertyMatchingResultList

java.util.List getPropertyMatchingResultList()

Returns:

a 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.
