In-Depth Information
-
use of media
: this axis relates to the temporal ordering and thus conditions the
use of temporal operators:
- sequential: reduces the grammar to the temporal operators excluding the use
of parallelism: anachronic, sequential, choice and iteration,
- parallel: limits the grammar to the temporal operators using the different types
of parallelism: concomitant, coincidental and parallel;
-
link between the information
: this axis relates to the semantic relation between
the information and thus conditions the semantic operators:
- combined: reduces the semantic operators for the operators: complementary,
complementary and redundant, partially redundant and totally redundant,
- independent: limits the semantic operators for the concurrent operator.
Thus, the four types of multimodalities can be defined as follows:
-
Concurrent type
: by using the temporal operators that are concomitant,
coincidental and parallel combined with the concurrent semantic operator:
I
::=
UIE |
(
op
temp
,op
sem
)(
I,I
) with
op
temp
∈{Ct,Cd,Pl}
and
op
sem
∈{Cc}
-
Alternated type
: with the anachronic, sequential, choice and iteration temporal
operators
combined
with
the
semantic
operators
that
are
complementary
and
redundant, partially redundant and totally redundant:
I
::=
UIE |
(
op
temp
,op
sem
)(
I,I
)
| It
(
n, I
) with
n ∈
N
with
op
temp
∈{An, Sq, Ch}
and
op
sem
∈{Cp,Cr,Pr,Tr}
-
Synergistic type
: by using the concomitant, coincidental and parallel temporal
operators combined with the semantic operators - complementary, complementary
and redundant, partially redundant and totally redundant:
I
::=
UIE |
(
op
temp
,op
sem
)(
I,I
) with
op
temp
∈{Ct,Cd,Pl}
and
op
sem
∈{Cp,Cr,Pr,Tr}
-
Exclusive type
: with the anachronic, sequential, choice and iteration temporal
operators combined with the concurrent operator:
I
::=
UIE |
(
op
temp
,op
sem
)(
I,I
)
| It
(
n, I
) with
n ∈
N
with
op
temp
∈{An, Sq, Ch}
and
op
sem
∈{Cc}

Allocation model
The proposed allocation model is based on the second stage of the refinement
process relating to the WWHT model. It includes the operators proposed in the
