A reasonably precise although not universal definition could be to take the data points from the study in relation to the use of those terms in the study.
I think the main idea though is that there is some structure in the memory that resembles a structure in the real world to some meaningful degree. One aspect of this is composition, the other is how closely it maps to the real world.
If it were literally just a lookup table where the indices did not correspond to physical proximity then it would definitely not be valid to say that this was really a world model in that context.
