Using predictive user models for language modeling on a personal device
First Claim
1. A system for the prediction of a user goal for command/control of a personal device, comprising:
- a user data store that stores information regarding a particular user'"'"'s behavior with respect to the personal device; and
, a predictive user model that receives a user input and employs statistical modeling of the information stored in the user data store to determine a likely command/control.

Abstract
A system and method for prediction of a user goal for command/control of a personal device (e.g., mobile phone) is provided. The system employs statistical model(s) that can predict a command based, at least in part, on past user behavior (e.g., probability distribution over a set of predicates, and, optionally arguments). Further, the system can be employed with a speech recognition component to facilitate language modeling for predicting the user goal. The system can include predictive user models (e.g., predicate model and argument model) that receive a user input (e.g., utterance) and employ statistical modeling to determine the likely command without regard to the actual content of the input (e.g., utterance). The system employs features for predicting the next user goal which can be stored in a user data store. Features can capture personal idiosyncrasies or systematic patterns of usage (e.g., device-related, time-related, predicate-related, contact-specific and/or periodic features).
