  • Patent number: 11429197
    Abstract: A Latin character conversion apparatus includes a code associator that associates each of a plurality of character keys assigned with Latin characters among a plurality of keys included in a keyboard with any of a plurality of character codes established by a character encoding scheme of the Unicode Standard, a character associator that associates the character code with a relevant code being another character code, a code converter that, in response to an instruction by a user that instructs any of the plurality of character keys, determines the character code associated with the instructed character key as a conversion candidate, and a character converter that, in response to an instruction by the user that instructs the character key serving also as a conversion key of the plurality of character keys with the conversion candidate determined, converts the conversion candidate into the relevant code associated with the conversion candidate.

  • Publication number: 20180011833
    Abstract: A syntax analyzing device includes: a syntax analyzing unit that analyzes syntax of a sentence received by a receiving unit, thereby acquiring a first analysis result, which is an analysis result having one or more elements constituting the sentence and parts of speech of the respective one or more elements and has one or more binary trees each having the parts of speech or the elements as nodes; a category acquiring unit that acquires categories of the respective one or more elements constituting the sentence; a category inserting unit that acquires a second analysis result in which the categories of the elements are respectively inserted between the elements and the parts of speech of the elements, which respectively correspond to the one or more categories, and constituting the first analysis result; and a learning unit that outputs the second analysis result acquired by the category inserting unit.

  • Publication number: 20170076199
    Abstract: A neural network 80 for aligning a source word in a source sentence to a word or words in a target sentence parallel to the source sentence, includes: an input layer 90 to receive an input vector 82. The input vector includes an m-word source context 50 of the source word, n?1 target history words 52, and a current target word 98 in the target sentence. The neural network 80 further includes: a hidden layer 92 and an output layer 94 for calculating and outputting a probability as an output 96 of the current target word 98 being a translation of the source word.
