  • Publication number: 20220188515
    Abstract: The presently disclosed method and system automatically diacritize written Arabic text for use with applications that require verbalizing Arabic text. A method may comprise converting a written sentence into a word sequence and identifying a target source word. The method then may comprise repeatedly overlaying and translating a context window at a plurality of positions in the word sequence to select a plurality of subsets of the word sequence contained within the context window. A diacritized form of the target source word may be generated in each of the word sequence subsets. A final diacritized form of the target source word may be selected from the plurality of diacritized forms based on a voting scheme. The voting scheme may include selecting the diacritized form that is generated the most or may be based on a system of weighting factors.

  • Patent number: 9191991
    Abstract: A mobile device having first and second RF transceivers performs a communication function in accordance with a communication protocol of the second RF transceiver. During performance of this function, the mobile device estimates the RF interference on a channel of the first RF transceiver, and stores parameters which characterize the estimated RF interference in association with an identifier corresponding to the function. These actions are repeated for a plurality of channels of the first RF transceiver, as well as for a plurality of different communication functions. When performing a communication function again, the mobile device receives an identifier corresponding to the function and retrieves stored parameters corresponding to the received identifier. The mobile device applies the retrieved parameters to the first RF transceiver for reducing the adverse effect of RF interference during reception on the channel of the first RF transceiver.

  • Patent number: 8325362
    Abstract: In one example, a system may suggest an order in which to read documents in a set. When a person has read a document in the set, the system may suggest the next document to read. The next document may be selected based on criteria such as the document's dissimilarity from the document(s) that have already been read. Choosing, as the next document, a document that is dissimilar from documents that have already been read exposes the reader to new information, thereby enhancing the reader's return on investment for the time spent reading the documents.
