Methods for automatic mapping 1/2String comparison

good indicator for a perfect match

Stem comparison improves the likelihood, but reduces confidence

Levenshtein distanceprovide only a very week indicator for similarity

Dictionary lookupgives a very high probability for a good match

Abbreviation lookupmay destroy valuable information

STASIS

Methods for automatic mapping 2/2WordNet synsets

used for further aggregation with scores from other plugins

Structural comparisonquality of this score heavily depends on the availability of metadata

Transitive link reductiongives a strong indication, but only if all links in between are correct

Reasoningprovides the best indicator for a perfect match
