Interactions between these three aspects are
represented in Figure 12.
Here we can distinguish the following situations:
A. Features explicitly requested by the user that appear in the active object as
well as in the user-profile;
B. Features requested by the user and appearing in the active object;
C. Features not requested that are a part of the user profile and that appeared in
the active object; and
D. Features that do not appear in the active object (we are not interested in
them).
Ratings obtained for each token in the MRS represent what the system believes are
user preferences and are used to filter out these objects temperatures of which are
below a certain threshold and rank the remaining ones (objects with highest scores
will be displayed first). We will omit discussion of a special case when there is no
object above the threshold. The MRS is processed in the following way:
1. Travel objects are to be returned to the user in two groups (buckets)
a. Objects requested explicitly by the user (via the query form) ??“ Group I
b. Objects not requested explicitly by the user but predicted by the system
to be of potential interest to the user ??“ Group II
Thus, for each active object we divide features according to the areas depicted
in Figure 11.
