Abstract

Disclosed is a method of word completion that does not require the user to change the character type of the input mode. The word-completion technique is widely used in keyboard-based input. It is also important for increasing the input speed of pen-based entry systems. However, in Japanese systems of this type, an input mode change is required according to the type of characters to be input (phonetic Kana characters or ideographic Kanji characters).

This text was extracted from an ASCII text file.
This is the abbreviated version, containing approximately 75% of the total text.

Method of Modeless Word Completion

      Disclosed is a method of word completion that does not require
the user to change the character type of the input mode.  The
word-completion technique is widely used in keyboard-based input.  It
is also important for increasing the input speed of pen-based entry
systems.  However, in Japanese systems of this type, an input mode
change is required according to the type of characters to be input
(phonetic Kana characters or ideographic Kanji characters).

      This invention makes it possible to complete words written in
either Kana or Kanji.  Fig. 1 shows an example of the dictionaries
used in this invention.  Kana and Kanji expressions are included for
each word entry, and are bidirectionally linked.  Each expression
thus leads to generation of the other expression in the pair.  A
pen-recognizer outputs multiple candidates for each written input
(ink data).

      In the example of Fig. 2, there are three candidates.  One
is a Kanji character 'Ya'), and the other two are Kana characters
('Ha' and 'Ri').  An appropriate dictionary is consulted on the basis
of candidate character types (Kana or Kanji).  For the Kana character
'Ha', the Kana dictionary gives 'Habikino-shi' and 'Hannan-shi'.  For
the character 'Ya', the Kanji dictionary gives 'Yao-shi'.  The
selected words are ranked according to their scores.  The following
is an example of a formula calculating each score.  Let the word T be
tffl1]tffl2],...,...
