  • Patent number: 8433556
    Abstract: A system and method for aligning words in parallel segments is provided. A first probability distribution of word alignments within a first corpus comprising unaligned word-level parallel segments according to a model estimate is calculated. The model estimate is modified according to the first probability distribution. One or more sub-models associated with the modified model estimate are discriminatively re-ranked according to word-level annotated parallel segments. A second probability distribution of the word alignments within the first corpus is calculated according to the re-ranked sub-models associated with the modified model estimate.
    Type: Grant

  • Publication number: 20050238008
    Abstract: Method and device provide for the encapsulation of control information in a real-time data stream. In one embodiment a method of encapsulating data in an information frame is provided. This information frame has a payload portion and a trailer portion wherein the trailer portion is designated for control data and the payload portion is designated for real-time data. In use control data is inserted into the payload portion of the information frame and an extension bit is used to signify the presence of control data in the payload portion of the information frame. The information frame is then transmited over a virtual circuit.

  • Publication number: 20050041797
    Abstract: A system and method for providing telephony and high-speed data access over a broadband access network, comprising a network interface unit (NIU) coupled to a backup local exchange carrier (LEC) line, the broadband access network coupled to the NIU, an intermediate point-of-presence (IPOP) coupled to the broadband access network, and at least one external access network coupled to the IPOP. The system also provides for a fail-safe mode in which the NIU supports the LEC line for lifeline services.
