Embodiment Construction

[0055] According to various embodiments of the present invention, various contextual information is obtained and applied to perform information processing functions in support of the operation of the virtual assistant. For purposes of description, "virtual assistant" is equivalent to the term "intelligent automated assistant," both of which refer to any information processing system that performs one or more of the following functions:

[0056] ● Interpreting human language input in speech and / or text form;

[0057] Manipulating a representation of user intent into an executable form, such as a representation of a task with steps and / or parameters;

[0058] Execution of tasks represented by calling programs, methods, services, APIs, etc.; and

[0059] • Generate an output response to the user in verbal and / or graphical form.

[0060] An example of such a virtual assistant is described in related U.S. Patent Application Serial No. 12 / 987,982, filed January 10, 2011, Attorney ...

Abstract

The present invention relates to the use of contextual information in a virtual assistant to facilitate the processing of commands. Virtual assistants use contextual information to supplement natural language or gesture input from users. Context helps clarify the user's intent and reduces the number of candidate interpretations for the user's input and reduces the user's need to provide excessive clarifying input. Context can include any available information that can be used by the assistant to supplement explicit user input to constrain information processing questions and / or personalize outcomes. Context can be used to constrain solutions at different stages of processing including, for example, speech recognition, natural language processing, task flow processing, and dialog generation.
