Information processing apparatus, information processing method, and information processing program

An information processing method, comprising:

• inputting a letter or a string of letters sequentially;
• determining whether a given letter is uppercase or lowercase;
• and
• outputting a candidate word corresponding to an input string of letters in the order in which the letters are input each time a letter is input, the candidate word including notation of each letter of the candidate word in conformity with notation of each letter of the input string of letters;
• storing a history of a word selected from the candidate words and a notation of the selected word, the history including the selected word and the notation of the selected word in association with a preceding word that is confirmed prior to the selected word and a notation of the preceding word;
• and
• outputting the selected word in the notation stored as a candidate word subsequent to the preceding word next time the preceding word displayed in the notation stored in the history is confirmed.

An information processing apparatus, comprising:

• an input unit through which a letter or a string of letters are sequentially input;
• a determination unit configured to determine whether a given letter input through the input unit is uppercase or lowercase;
• an output unit configured to output a candidate word corresponding to an input string of letters in the order in which the letters are input through the input unit each time a letter is input, the output unit outputting the candidate word according to a result generated by the determination unit, the notation of each letter of the candidate word in conformity with notation of each letter of the input string of letters;
• a dictionary, configured to store each word in one of uppercase, lowercase, and a combination of at least one uppercase letter and at least one lowercase letter;
• a storage unit configured to store notation information indicating whether the letter is uppercase or lowercase as determined by the determination unit;
• a search unit configured to search the dictionary for a word corresponding to an input string of letters in the order in which the letters are input through the input unit each time a letter is input;
• a converter configured to convert a notation of each letter included in the word retrieved by the search unit according to the notation information stored in the storage unit, wherein
• the output unit is configured to output the word whose notation is converted by the converter as the candidate word,
• the determination unit determines whether or not the letter input through the input unit is uppercase or lowercase after determining whether or not a diacritic is added to the letter, and
• when converting the notation of each letter included in the word retrieved from the dictionary, the converter converts the notation of the letter after determining whether or not a diacritic is added to the letter.
