Abstract: A system and method for intelligent caching and network management includes contextual information representing needs of a user. A contextual system determines settings based on the contextual information and determines services and devices available for the user, in accordance with the contextual information. A predictor receives the contextual information, the settings, the services available and the devices available and predicts the needs of the user to make resources available to the user in accordance with predictions.

Abstract: An authentication framework is provided which enables dynamic user authentication that combines multiple authentication objects using a shared context and that permits customizable interaction design to suit varying use r preferences and transaction/application requirements. Such a framework provides a high degree of flexibility, accuracy, convenience and robustness. In one illustrative aspect of the invention, an automated technique for user authentication comprises the following steps/operations. First, user input i s obtained. At least a portion of the user input is associated with two or mor e verification objects. Then, the user is verified based on the two or more verification objects in accordance with at least one verification policy operating on a context shared across the two or more verification objects. T he user authentication technique of the invention may preferably be implemented in a flexible, distributed architecture comprising at least one client devic e coupled to at least one verification server. The client device and the verification server may operate together to perform the user authentication techniques of the invention.

Abstract: A method of translating a natural language input 10 into a formal computer command 14 comprises the steps of translating the input command into a category at a first translation level 102 with a further translation at a second level 102 associated with the category. Further translation may occur at additional levels as determined by the preceding translation level. Preferably a plurality of models 212 will be provided at each level, each model being associated with a category and comprising a subset of formal commands. Preferably the formal command 14 will be applied to an application 16. In this instance the first level categories can be associated with the application, the second and subsequent levels being associated with specific application functions.. In a second embodiment probability scoring 214 may be used to determine which category should be used at the next level of translation where at least two possible candidate categories have been identified.. A method of building the category models is also claimed.

Abstract: A system and method for verifying user identity, in accordance with the present invention, includes a conversational system (114) for receiving inputs from a user (110) and transforming the inputs into formal commands. A behavior verifier (118) is coupled to the conversational system (114) for extracting features from the inputs. The features include behavior patterns of the user. The behavior verifier (118) is adapted to compare the input behavior to a behavior model (214) to determine if the user is authorized to interact with the system.

Abstract: In accordance with the invention, a method and system for accessing a dialog system 101 employing a plurality of different clients 100, includes providing a first client device for accessing a conversational system 300 and presenting a command to the conversational system 300 by converting the command to a form understandable to the conversational system. The command is interpreted by employing a mediator 302, a dialog manager 303 and a multi-modal history 304 to determine the intent of the command based on a context of the command. A second client device is determined based on a predetermined device preference stored in the conversational system. An application is abstracted (400) to perform the command, and the results of the performance of the command are sent to the second client device.

Abstract: A system and method of the present invention for determining and maintaining dialog focus in a conversational speech system includes presenting a command associated with an application to a dialog manager. The application associated with the command is unknown to the dialog manager at the time it is made. The dialog manager determines a current context of the command by reviewing a multi-modal history of events. At least one method is determined responsive to the command based on the current context. The at least one method is executed responsive to the command associated with the application.
