Patent Images
1. A word recognition system for recognizing an input signal entered via a shorthand-on-keyboard interface, the system comprising:
- a core lexicon comprising commonly used words;
an extended lexicon comprising words not contained in the core lexicon;
a recognition module for recognizing words associated with the input signal;
a selector module for outputting an output word associated with the input signal from the core lexicon; and
a module for admitting a candidate word associated with the input signal to the core lexicon, upon selection of the candidate word by the user.

Abstract
A word pattern recognition system improves text input entered via a shorthand-on-keyboard interface. A core lexicon comprises commonly used words in a language; an extended lexicon comprises words not included in the core lexicon. The system only directly outputs words from the core lexicon. Candidate words from the extended lexicon can be outputted and simultaneously admitted to the core lexicon upon user selection. A concatenation module enables a user to input parts of a long word separately. A compound word module combines two common shorter words whose concatenation forms a long word.

7. A word recognition method for recognizing a input text entered via a shorthand-on-keyboard interface, the method comprising:
-
storing commonly used words on a core lexicon;
storing words not contained in the core lexicon in an extended lexicon;
recognizing words associated with the input signal;
outputting an output word associated with the input text from the core lexicon; and
admitting a candidate word associated with the input text to the core lexicon, upon selection of the candidate word by a user. - View Dependent Claims (8, 9)

10. A computer program product having program codes stored on a computer-usable medium for word for recognizing an input signal entered via a user input interface, comprising:
-
a core lexicon comprising commonly used words;
an extended lexicon comprising words not contained in the core lexicon;
a program code for recognizing words associated with the input signal;
a program code for outputting an output word associated with the input signal from the core lexicon; and

11. A system for recognizing an input signal entered via a shorthand-on-keyboard interface and for allowing a stem and an affix of the input text to be combined, the system comprising:
-
a concatenation module for recognizing the input signal as an input affix;
the concatenation module further recognizing a candidate word as neighboring candidate word;
a compound output module for retrieving a set of words in a lexicon containing the input affix;
a ranking module for ranking the set of words containing the input affix according to a similarity function that compares each lexicon word in the set of words containing the input affix, with a string containing the candidate word and the input affix; and
the compound word module outputting a highest ranked lexicon word in the set of words containing the input affix. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 21)

20. A method for recognizing an input text entered via a shorthand-on-keyboard interface and for allowing a stem and an affix of the input text to be combined, the method comprising:
-
recognizing the input text as an input affix;
if the input text is recognized as the input affix, recognizing a candidate word as neighboring candidate word;
retrieving a set of words in a lexicon containing the input affix;
ranking the set of words containing the input affix according to a similarity function by comparing each lexicon word in the set of words containing the input affix, with a string containing the candidate word and the input affix; and
outputting a highest ranked lexicon word in the set of words containing the input affix.
