Description

This experimental AlignmentGenerator tries to tackle large scale ontology alignment, for which other approaches fail due to high memory and/or performance requirements. The general idea is a divide and conquer approach, continously aligning a number of parts of the ontologies and joining them it to a single, large alignment.

Specification

Parameters

Parameter name ValueType Default Description
PARAM_TAXONOMY_ONLY Boolean FALSE Defines whether only the taxonomy (classses) should be aligned. This defaults to aligning the classes along with the properties.
PARAM_THRESHOLD Double 0.0 This standard parameter forces the algorithm to drop all relations with lesser confidence. However, this parameter must be chosen carefully, since the confidences produced by the BordaCount? algorithm are no explanatory values. It would probably make more sense, to apply a threshold to each SimilarityMeasure, but this requires for a set of threshold parameters and not just a single one.
