The relationship to refine criteria into more specific and classified criteria
allows us to specify an order among the nodes sharing the same direct father
node. The level of expertise of the method user targeted by the method chunk
under qualification is another example of meaningful criteria. Different levels
of expertise may be distinguished: expert method users, medium method users,
and beginner method users. If a method user searches for method chunks
satisfying the expert method users’ criteria and no chunks are found, maybe
he or she would be interested in looking for method chunks dedicated to medium
method users, but not to method chunks dedicated to beginner method
users, which would seem unsuitable. Ranking starts from 1 to n (one by one);
n is the number of nodes sharing the same direct father node. Therefore, we
integrated this kind of refinement relationship into our reuse-frame structure.
The refinement into nodes to specify more specific and classified criteria may
be helpful when retrieving method chunks to find method chunks qualified
by criteria classified as previous or next to the criteria of the method chunk
or of the user situation under consideration.
