Abstract: A character input device includes a character input unit that receives an input character, a suggestion list management unit that converts the input character, a suggestion list generator that generates a conversion suggestion list through conversion of the input character, a suggestion display including a standard-suggestion display area for displaying the conversion suggestion list, an operation detector that detects movement of a divisional suggestion included in the conversion suggestion list, and a suggestion division management unit that generates a divisional-suggestion display area different from the standard-suggestion display area in the suggestion display in response to the movement of the divisional suggestion. The suggestion division management unit associates the divisional suggestion with the divisional-suggestion display area, and outputs the divisional suggestion to the divisional-suggestion display area.

Abstract: An information processing apparatus includes an input log storage unit, an interest information prediction unit, a relevant information obtaining unit, and a relevant information output unit. The input log storage unit stores an input log of text data for a predetermined application. The interest information prediction unit predicts, from the input log of the text data, interest information to interest an individual user or a user group that has input the text data. The relevant information obtaining unit obtains relevant information relevant to the interest information. The relevant information output unit outputs the relevant information.

Abstract: A character string input apparatus has a display unit that displays a keypad image in which a plurality of character keys are arranged, on a screen of a display device, an operation position detector that detects pressed positions on the screen of the display device, a score calculator that calculates, for each of the character keys of the keypad image, scores of the pressed positions on the screen of the display device, a score data generator that generates, for each of the pressed positions on the screen of the display device detected by the operation position detector during a character string input period, score data in which the scores for the character keys calculated by the score calculator are registered, and an input character string inference unit that infers a character string that was input, using the score data generated by the score data generator.
