Method Detail

execute

public static AMapping execute(ACache sourceCache,
                               ACache targetCache,
                               String metricExpression,
                               double threshold,
                               String sourceVar,
                               String targetVar,
                               RewriterFactory.RewriterType rewriterType,
                               ExecutionPlannerFactory.ExecutionPlannerType executionPlannerType,
                               ExecutionEngineFactory.ExecutionEngineType executionEngineType)

Execute a LS given a string metric expression and a double threshold, generating a mapping.

Parameters:

sourceCache - Resources from source KB

targetCache - Resources from target KB

metricExpression - Specifies which measures are used and how they are combined to assert the similarity between two resources

threshold - Minimal similarity value for resource pairs to be included in the generated mapping

sourceVar - Name of SPARQL variable for resources from source KB

targetVar - Name of SPARQL variable for resources from target KB

rewriterType - Specifies rewriter module to use

executionPlannerType - Specifies executionPlanner module to use

executionEngineType - Specifies executionEngine module to use

Returns:

Mapping of resources in sourceCache to resources in targetCache with similarity > threshold

execute

public static AMapping execute(ACache sourceCache,
                               ACache targetCache,

                               String sourceVar,
                               String targetVar,
                               RewriterFactory.RewriterType rewriterType,
                               ExecutionPlannerFactory.ExecutionPlannerType executionPlannerType,
                               ExecutionEngineFactory.ExecutionEngineType executionEngineType)

rewriterType - Specifies rewriter module to use

executionPlannerType - Specifies executionPlanner module to use

executionEngineType - Specifies executionEngine module to use

Returns:

Mapping of resources in sourceCache to resources in targetCache with similarity > threshold

execute
