Abstract: Methods, computing devices, and computer-program products are provided for implementing a virtual personal assistant. In various implementations, a virtual personal assistant can be configured to receive sensory input, including at least two different types of information. The virtual personal assistant can further be configured to determine semantic information from the sensory input, and to identify a context-specific framework. The virtual personal assistant can further be configured to determine a current intent. Determining the current intent can include using the semantic information and the context-specific framework. The virtual personal assistant can further be configured to determine a current input state. Determining the current input state can include using the semantic information and one or more behavioral models. The behavioral models can include one or more interpretations of previously-provided semantic information.

Abstract: The present invention relates to a method and apparatus for adding new vocabulary to interactive translation and dialog systems. In one embodiment, a method for adding a new word to a vocabulary of an interactive dialog includes receiving an input signal that includes at least one word not currently in the vocabulary, inserting the word into a dynamic component of a search graph associated with the vocabulary, and compiling the dynamic component independently of a permanent component of the search graph to produce a new sub-grammar, where the permanent component comprises a plurality of words that are permanently part of the search graph.

Abstract: Methods and apparatus for efficiently maintaining updated information on client/server object-oriented computing systems are disclosed. In accordance with one aspect of the present invention, a method for transmitting a packet of data from a first computing system to a second computing system in a client/server object-based computing system includes identifying the packet of data using the first computing system and attempting to send the packet of data from the first computing system to the second computing system. Once the attempt is made to send the packet of data, it is determined whether the packet of data is received by the second computing system. An acknowledgment is sent from the second computing system to the first computing system when it is determined that the packet of data is received by the second computing system. The acknowledgement indicates that the packet of data is received by the second computing system.

Abstract: In one embodiment, a method for automating or arranging a group communication among at least two participants includes receiving a user request (e.g., from one of the participants) for the group communication and delegating at least a portion of the user request to at least one service provider for processing. Delegation is based on general strategies for satisfying user requests, as well as knowledge of the capabilities of the available service providers.

Abstract: A method and apparatus are provided for performing speech recognition using observable and meaningful relationships between words within a single utterance and using a structured data source as a source of constraints on the recognition process. Results from a first constrained speech recognition pass can be combined with information about the observable and meaningful word relationships to constrain or simplify subsequent recognition passes. This iterative process greatly reduces the search space required for each recognition pass, making the speech recognition process more efficient, faster and accurate.

Abstract: Described is an internetworking system having various mobile ad hoc extensions to the Internet that are particularly suited to the dynamic environment of mobile ad hoc networks. The internetworking system includes any combination of a link-state routing protocol for disseminating topology and link-state information over a multi-hop network comprised of nodes, a neighbor discovery protocol that can detect the appearance and disappearance of new neighbor nodes, an address format that facilitates deployment of IPv6 nodes in a predominantly IPv4 network infrastructure, a queuing mechanism that can update information upon resuming interrupted communications between nodes, and dynamic network measurement techniques for adaptively using wireless bandwidth when establishing and maintaining connections between nodes and a server.
