Talvez debería tentar con algunhas variantes ortográficas:
information propagation » information presentation, information organization
propagation model » propagation case
precision data » precision dairy, precision a, precision cut
decision data » decisions data, decision gate, decision game
decision aid » decision _

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 propagation model ((precision data) OR (((decision data) OR (decision aid)))) lines~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information propagation model ((precision data) or (((decision data) OR (decision aid)))) lines~".
• Adding a wildcard symbol may retrieve word variants: information propagation model ((precision data) or (((decision data) OR (decision aid)))) lines*.
