Suppose I have a taxonomy, which describes animals, that looks like this
+ Animal + Mammal + Cat + Dog
And I want people to use this taxonomy to label a set of 100 images of cats and dogs. Imagine that, instead of using 'cat' and 'dog', people have mostly described these images as 'animal' and 'mammal', say, for 90% of the images.
I want a word or phrase to describe this 'misuse of too generic concept', i.e., they should've used 'cat' and 'dog' that is more specific in the taxonomy to describe the data. Instead, they chose to use a more generic one that would not be as specific or as appropriate.
At the moment I just say, as above, 'misuse of too generic concept'. But is there a better and shorter way to refer to this problem? e.g., 'overuse of generic concept', but that does not seem to capture the problem here...
