Difficult matches. caTissue and ProtLIMS UML class-attribute compared to CDE class-property pairs are shown here where the dice algorithm scored lower than expected. Reduced performance of the algorithms tends to occur when abbreviations and synonyms appear. For example ProtLIMS gel2d is used in UML to represent 2 dimensional electrophoresis gel.
