influence than future accesses. The equation establishes that given two accesses with
a year of difference, the newer one will have double influence than the older one.
This definition introduces in the system two important and useful capabilities:
•
The pertinences will be updated according to the aging of the access and the
decreasing relevance.
•
The system will be adapted automatically to future accesses patterns and needs,
that can even allow us to define new contexts.
Then the system will update the pertinence of the data groups having more influence
the newer accesses and enable the system to adapt to future needs.
