SimilarityMeasure: Stringbased

Developer: Björn Endres

Description

This module determines the similarity of two ontology entities by calculating a simple string alikeness on the labels of these entities. The PhaseLibs ontology model provides these labels with the getName() method. The algorithm is based on a 3-gram matcher by ​Micheal Sintek.

Characteristics

In order to demonstrate the basic characteristics of this SimilarityMeasure, here some examples:

Frame A name	Frame B name	Measure value
Analyser	AnaLyseR	1.00
Analyser	Analyzer	0.50
Analyser	Sample-Analysis	0.59
Sample-Analysis	Analyser	0.30

Evaluation/Performance

This measure was used for some basic evaluation tests. You can see the results here, second column.
