A virtual assistant uses context information to supplement natural language or gestural input from a user. Context helps to clarify the user's intent and to reduce the number of candidate interpretations of the user's input, and reduces the need for the user to provide excessive clarification input. Context can include any available information that is usable by the assistant to supplement explicit user input to constrain an informa tion-processing problem and/or to personalize results. Context can be used to constrain solutions during various phases of processing, including, for example, speech recognition, natural language processing, task flow processing, and dialog generation. - 64 - Application Dialog Preferences history and and Usage assistant History memory Device 1072 1052 sensor data User Input Output to user 2704 Virtual 2708 Assistant Event Context Other actions Current Personal Application Databases Personal Context 1060 (e.g., CosticDt Contacts) |
