Appl. No.:

10/808126

Inventors:

Anurag Gupta - Palatine IL, US
Tasos Anastasakos - San Jose CA, US

International Classification:

G06F017/27
G10L015/04
G06K009/72
G09G005/08

US Classification:

704009000, 704251000, 382229000, 345157000

Abstract:

A multi-modal input fusion (MMIF) () is made scalable based on the resources available. When system resources are low, the MMIF module will limit the number of elements in each set of related interpretations. Additionally, the number of sets generated can be increased or reduced based on an amount of system resources available. In order to accommodate the scalable MMIF module, a resource profile () is provided to the MMIF describing the amount of resources (memory, processing power, etc.) available, and/or an amount of resources the MMIF module can utilize. Based on the amount of resources the MMIF module calculates threshold values that are used to adjust the number of sets produced and the number of elements included within each set.

US Classification:

715809000, 715700000, 704009000

Abstract:

A method for operating a multi-modal dialog system () is provided. The multi-modal dialog system () comprises a plurality of modality recognizers (), a dialog manager (), and a grammar generator (). The method interprets a current context of a dialog. A template () is generated, based on the current context of the dialog and a task model (). Further, a current modality capability information () is obtained. Finally, a multi-modal grammar () is generated based on the template () and the current modality capability information ().

International Classification:

G06F 17/00

US Classification:

707102000

Abstract:

A method and a system for integrating multimodal interpretations (MMIs) in user inputs to a data processing system () are provided. The method includes generating () a set of MMIs, based on the user inputs collected during a turn. The set of MMIs includes at least semantic relationship function, the semantic relationship function denoting a semantic relationship between values determined from the user inputs entered through one or more of the at least one input modality, the semantic relationship function comprising at least one semantic operator. The method further includes generating () sets of joint MMIs. Each set of joint MMIs includes MMIs of semantically compatible types. The method further includes resolving () the reference values of the references of each set of joint MMIs to generate corresponding sets of reference resolved MMIs. The method further includes generating () an integrated MMI for each set of reference-resolved MMIs. The generation of the integrated MMI is carried out by using semantic operator based fusion.

Anurag Gupta - Palatine IL, US

International Classification:

G10L 15/04

US Classification:

715809000, 704251000

Abstract:

A method and a system for resolving cross-modal references in user inputs to a data processing system () are provided. The method includes generating () a set of multimodal interpretations (MMIs), based on the user inputs collected during a turn. The set of MMIs includes at least one reference, and each reference includes at least one reference variable. The method further includes generating () one or more sets of joint MMIs. Each set of joint MMIs includes MMIs of semantically compatible types. The method further includes generating () one or more sets of reference-resolved MMIs, by resolving the reference variables of the references contained in the sets of joint MMIs. The method further includes generating () an integrated MMI for each set of reference resolved MMIs. The generation of an integrated MMI is carried out by unifying the MMIs in a set of reference resolved MMIs.

International Classification:

G10L 11/00

US Classification:

704275000

Abstract:

A method and a system for controlling a set of input modalities in a multimodal dialog system are provided. The method includes selecting () a sub-set of input modalities that a user can use to provide user inputs during a user turn. The method further includes dynamically activating () the input modalities that are included in the sub-set of input modalities. Further, the method includes dynamically deactivating () the input modalities that are not included in the sub-set of input modalities.
