[RavenclawDev 180] Re: grounding_manager_configuration setting inconfig file of DM

[Antoine Raux]

Hi Svetlana,

 

Have you looked at the confidence value for the input in both cases? This is
one of the features that Helios sends to the DM for each input. It is
possible that "where class" has a low confidence for some reason (e.g.
segmented parse.) and RC rejects it. Normally if your grammar gives a full
parse for "where class" that shouldn't happen (at least on typed input) but.

Subject: [RavenclawDev 179] grounding_manager_configuration setting inconfig
file of DM

 


I have encountered an issue with binding a concept in DM depending on a user
utterance.

in my DM I have a grammar mapping. "@(...)[Question.where_event]>where,"


The user can ask a question in multiple ways:
where class
where is class
where is the class
what is the location the class
..

for all of these entries PHOENIX produces identical parse

[Question] ( [where_event] ( WHERE ) )
Features
[EventTypeSpec] ( [event_type] ( [event_type_singular] ( MEETING ) ) )

" } )

When a configuration file passed to the DM in -config has an entry:
grounding_manager_configuration =
turns:default;concepts:default;beliefupdatingmodel:npu


if a user types:
"where is the class"    DM does not bind the concepts, but if the user types

"where class"             DM binds the concepts.

When the grounding_manager_configuration is taken out of DM, the binding
succeeds for both utterances.

Can this be explained?  Do you think there may be a problem with my grammar
or something in my DM? 
The grammar of the Phoenix parser should not matter because in all cases the
parses are identical, right?

thank you

Svetlana
