Class RelationBasedBasisMapping

java.lang.Object

edu.ucla.sspace.basis.AbstractBasisMapping<DependencyPath,String>

edu.ucla.sspace.dv.RelationBasedBasisMapping

All Implemented Interfaces:

BasisMapping<DependencyPath,String>, DependencyPathBasisMapping, Serializable

public class RelationBasedBasisMapping
extends AbstractBasisMapping<DependencyPath,String>
implements DependencyPathBasisMapping

A BasisMapping implementation where each word and relation combination corresponds to a unique dimension. For example "bowl" occuring with the "SBJ" relation will be treated as a seperate dimension than "bowl" with the "OBJ" relation.
