Has
Z
the same relevant qualities? How much; how many? Does
Z
belong to the same
class/set of
Y
, based on the relevant features?
Does
τ
share the same relevant requirements as
τ
? Does
τ
belong to the same kin/class/set
of services/goods as
τ
?
6.6.3 Formal Analysis
In more systematic and formal terms we have tasks (
τ
) and agents (
Ag
): with
τ
∈
T
≡
{
τ
1
,
...
,
τ
n
}
can be considered composed
of both a set of actions and the modalities of their running, this we call
properties
:
, and
Ag
∈
AG
≡
{
Ag
1
,
...
,Ag
m
}
. We can say that each task
τ
τ
≡{
p
1
,...,
p
n
}
(6.14)
we consider this composition from the point of view of an agent (
Ag
X
):
Bel
Ag X
(
τ
≡{
p
1
,...,
p
n
}
)
(6.15)
In general each of these properties could be evaluated with a value ranging between a
minimum and maximum (i.e.:
0,1
): representing the complete failure or the full satisfaction
of that action. So in general: 0
.
Of course, not all the properties of a task have the same relevance: some of them could be
considered indispensable for the realization of the task, others could be considered useful in
achieving greater success.
If we insert an apex
c
to all the properties that the agent (
Ag
X
) considers indispensable (
core
properties
) for that task, we can write:
≤
p
i
≤
1 with
i
∈
{
1, .. , n
}
p
1
,...,
p
k
}∪{
τ
≡{
p
1
,...,
p
m
}

Ag X

NC
We call
τ
≡
{
...
and
τ
≡
{
p
1
,
...
,
p
m
}
,so
C
NC
τ
=
τ
∪
τ
(6.17)
The set of the core properties is particularly relevant for grouping tasks into classes and for
extending the reasoning behind generalization or specification.
Analogously, we can define the set of the
features f
AgY
for an agent (
Ag
Y
):
f
AgY
≡{
f
Y
1
,...,
f
Yn
}
(6.18)
we consider this composition from the point of view of an agent (
Ag
X
):
Bel
Ag X
(
f
AgY
≡{
f
Y
1
,...,
f
Yn
}
)
(6.19)
Also in this case, each of these features could be evaluated with a value ranging between a
minimum and a maximum (i.e.:
0,1
): representing the complete absence or the full presence of
that feature in the agent
Ag
Y
, from the point of view of
Ag
X
. So in general: 0
≤
f
i
≤
1
with i
∈
{
Y
1
,...,
.
Given the previous definitions, we can say that
Ag
X
could trust
Ag
Y
on the task
Y
n
}
τ
if
Ag
X
has
the following beliefs: (6.19), (6.16) and
C
Bel
Ag X
(
∀
p
i
∈
τ
,
∃{
f
i
}∈{
f
Y
1
,...,
f
Yn
}|{
f
i
} =∅∩
p
i
i s satisfied from
{
f
i
}
)
