= SimilarityMeasure: Stringbased =

Developer: [mailto:endres@dfki.uni-kl.de 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 [http://www.dfki.uni-kl.de/~sintek/ 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 [wiki:BugFix008 here], second column.

== Specification ==
=== Intitialisation ===
The SimilarityMeasure main class is
 {{{de.dfki.km.phaselib.impl.similarities.stringbased.StringBasedSimilarity}}}

Initialisation is straight forward: 
 {{{new StringBasedSimilarity()}}}

=== Parameters ===
