  • Publication number: 20220292257
    Abstract: An extraction unit extracts candidates including predictive candidates, as candidates corresponding to an input character string. A control vocabulary storage unit stores a control vocabulary to be learned with teaching material. A determination unit determines whether a usage mode is a first mode or a second mode. An output control unit outputs the candidates in an arrangement order according to priority. When the usage mode is the first mode, the output control unit excludes, from the candidates to be output, any words in the control vocabulary extracted as predictive candidates. Also, when the usage mode is the second mode, the output control unit increases the priority of any words in the control vocabulary extracted by the extraction unit as predictive candidates, among the candidates to be output.
