Do some citeseer searches for NIAM, nijssen and halpin. They set the reference point for conceptual modelling about 20 years ago.
Since that time, I have seen nothing I would consider a groundshaking improvement; although, Jan or Vadim might have a better idea if something significantly changed the state of the art in recent years.
