Abstract
Die Vorteile internationaler Verbundsysteme werden durch Schwierigkeiten bei der Inhaltserschließung gefährdet. Abweichungen des tatsächlichen Selektionsergebnisses vom gewünschten Selektionsziel sind sprachlich bedingt; sie werden insbesondere durch Polysemie, Kontextabhängigkeit und syntaktische Ambiguität verursacht. Unter mehrsprachigen Bedingungen verschlechtert sich die Selektivität; es entstehen sprachabhängig unterschiedliche Selektionsergebnisse. Verbesserung ist nur bei Schaffung und sachgerechter Anwendung eines solchen multilingualen Thesaurus zu erreichen, der größtmögliche semantische Isomorphie (klare und übereinstimmende Begriffsabgrenzung) zwischen den Vokabularen und exakte semantische Äquivalenz zwischen den Deskriptoren gewährleistet. Dies erfordert hohe Aufwendungen, ist aber wichtiger als die Speicherung großer Mengen schlecht selektierbarer Dokumentationseinheiten
