  • Patent number: 10504508
    Abstract: A dialog management unit (31) selects a response template corresponding to a dialog state with a user and outputs a term symbol included in the response template to a comprehension level estimating unit (30). The comprehension level estimating unit (30) outputs the user's comprehension level of the input term symbol to the dialog management unit (31). A response generating unit (32) generates a response sentence on the basis of the response template selected by the dialog management unit (31), adds an explanatory sentence to the response sentence depending on the user's comprehension level of the term input from the dialog management unit (31), and outputs the response sentence.

  • Patent number: 10037758
    Abstract: A voice recognizer 3 generates plural voice recognition results from one input speech 2. For each of the voice recognition results, an intent understanding processor 7 estimates an intent to thereby output one or more candidates of intent understanding results and scores of them. A weight calculator 11 calculates standby weights using setting information 9 of a control target apparatus. An intent understanding corrector 12 corrects the scores of the candidates of intent understanding result, using the standby weights, to thereby calculate their final scores, and then selects one from among the candidates of intent understanding result, as an intent understanding result 13, on the basis of the final scores.

  • Publication number: 20160163314
    Abstract: An intention estimated-weight determination processor 9 determines an intention estimated weight on the basis of an intention hierarchical graphic data 8 and an activated intention. A transfer node determination processor 10 determines an intention to be newly activated through transition, after correcting an intention estimation result according to the intention estimated weight. A dialog turn generator 13 generates a turn of dialog from the activated intention. A dialog management unit 2 controls, when a new input is provided due to the turn of dialog, at least one process among processes performed by an intention estimation processor 7, the intention estimated-weight determination processor 9, the transition node determination processor 10 and the dialog turn generator 13, followed by repeating that controlling, to thereby finally execute a setup command.

  • Publication number: 20050002955
    Abstract: A monoclonal antibody specific to Nap was prepared by using a crude membrane fraction from a cell line which has a high affinity to Nef as an antigen. A cDNA clone which encodes Nap was obtained by screening a cDNA library of said cell line utilizing the specific antibody. The nucleotide sequence of this cDNA was elucidated whereupon the full amino acid sequences of human Nap was identified. Since the anti-Nap monoclonal antibody inhibits the binding of Nef to Nap, it can be used as a new therapeutic agent for AIDS. In addition, it can be applied for the diagnosis of AIDS by clarifying the relation between the expression of Nap and the development of AIDS. Nap can be utilized for binding experiments to Nef.

  • Patent number: 6577203
    Abstract: This invention provides a voltage controlled oscillator that improves the linearity of frequency variable characteristics and increases the range of frequency that can be varied by a control voltage. A resistor circuit is connected between a piezoelectric resonator X and an oscillator circuit. The resistor circuit includes a plurality of oscillation-amplitude adjusting resistors Rs1 to Rsn and corresponding switches SW1 to SWn. The resistor circuit adjusts the amplitude of oscillation. When a control voltage Vc applied to a varactor Cv is at a low potential, clipping by a forward voltage of the varactor Cv is suppressed, and the frequency is linearly changed by the control voltage Vc within a range of a low potential to a high potential.
