Intelligent Assistant
Using the Assistant
18-17
Based on the definition above, you can derive a
my_other_action
template that
holds the value
'my_action
in its
isa
slot, as in the following example:
my_other_action := {
// name of this action
value:
"my other action",
// subclass of 'dyna_user_action
isa:
'my_action,
// words matching this action
lexicon: ["leap", "lunge"]
}
You can take a similar approach to define your own target object types by placing
the
'dyna_user_obj
symbol in your target template's
isa
slot. For example,
you can define a template
my_target
that is a
dyna_user_obj
and use its
symbol in this slot also, as in the following code fragment:
my_target := {
value:
"my target"
// name of this target
isa:
'dyna_user_obj // must use this value
}
Based on the definition above, you can derive another target template from
my_target
, and store the value
'my_target
in its
isa
slot, as in the following
example:
my_other_target := {
value:"my other target",// name of this targe
isa:
'my_target,
// subclass of 'dyna_user_obj
}
Implementing the PostParse Method
18
Your
PostParse
method implements the behavior your application provides
through the Assistant. This method resides in the
PostParse
slot of your
task template. It is called after all the templates in the
signature
slot have
been matched.
Your
PostParse
method must provide any behavior required to complete the
specified task, such as obtaining additional information from the
ParseUtter
result frame as necessary, and handling error conditions.
