guidelines for users can be recommended in the guideline recommendation phase.
Then, we shall describe in detail the different processes involved in

lines, where
DG
i
and
EG
j
are diet and exercise guidelines for all 1 ≤
i
≤ |
DG
| and 1
≤
j
≤ |
EG
|, and |
DG
| and |
EG
| are numbers of diet and exercise guidelines respective-
ly. Let
PEI
n
,
k
be the
n
-level of the
k
-th physical examination item in a report, where
|
SI
| is number of physical examination items in a report and |
NL
| is a user-specified
value of levels of a physical examination item for discretizing the vital sign of physi-
cal examination item for all
n
(1 ≤
n
≤ |
NL
|) and
k
(1 ≤
k
≤ |
SI
|). For example, Table 1
lists examples of discretization of physical examination items.
