default RDFResourceTree	getLGG(List<RDFResourceTree> trees, boolean learnFilters) Returns the Least General Generalization of a list of RDF resource trees.
default RDFResourceTree	getLGG(RDFResourceTree tree1, RDFResourceTree tree2) Returns the Least General Generalization of two RDF resource trees.
RDFResourceTree	getLGG(RDFResourceTree tree1, RDFResourceTree tree2, boolean learnFilters) Returns the Least General Generalization of two RDF resource trees.

Method Detail

getLGG

default RDFResourceTree getLGG(RDFResourceTree tree1,
                               RDFResourceTree tree2)

Returns the Least General Generalization of two RDF resource trees.

Parameters:

tree1 - the first tree

tree2 - the second tree

Returns:

the Least General Generalization

getLGG

RDFResourceTree getLGG(RDFResourceTree tree1,
                       RDFResourceTree tree2,
                       boolean learnFilters)

Returns the Least General Generalization of two RDF resource trees. It can be forced to learn filters on literal values.

Parameters:

tree1 - the first tree

tree2 - the second tree

learnFilters - whether to learn filters on literal values

Returns:

the Least General Generalization

getLGG

default RDFResourceTree getLGG(List<RDFResourceTree> trees)

Returns the Least General Generalization of a list of RDF resource trees.

Parameters:

trees - the trees

Returns:

the Least General Generalization

getLGG

default RDFResourceTree getLGG(List<RDFResourceTree> trees,
                               boolean learnFilters)

Returns the Least General Generalization of a list of RDF resource trees. It can be forced to learn filters on literal values.

Parameters:

trees - the trees

learnFilters - whether to learn filters on literal values

Returns:

the Least General Generalization
