Perhaps you should try some spelling variations:
information models » information modeling, information modelling
informatik modelle » informatik modell, information modelle, geoinformatik modelle
information model » information modeling

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((information models) OR (information model)) ) OR ( informatik modelle )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((information models) OR (information model)) ) or ( informatik modelle ))".
• Adding a wildcard symbol may retrieve word variants: (( ((information models) OR (information model)) ) or ( informatik modelle ))*.
