Input recognition using multiple lexicons
First Claim

1. A word recognition system for recognizing an input signal entered by a user via a shorthand-on-keyboard interface, the system comprising:
- a core lexicon comprising commonly used words,wherein the commonly used words were selected for the core lexicon based on an associated frequency of use value for each word being above a pre-determined threshold, andwherein the frequency of use values are not based on candidate selections by the user;
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, from the extended lexicon to the core lexicon, a candidate word associated with the input signal, upon a first selection of the candidate word by the user, to create an augmented core lexicon.

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.

8. A word recognition method for recognizing an input text entered via a shorthand-on-keyboard interface, the method comprising:
-
storing commonly used words on a core lexicon, wherein the commonly used words were selected for the core lexicon based on an associated frequency of use value for each word being above a pre-determined threshold, and wherein the frequency of use values are not based on candidate selections by the user; storing at least one word not contained in the core lexicon in an extended lexicon; recognizing, via one or more processors, words associated with the input text; outputting, via the one or more processors, an output word associated with the input text from the core lexicon; and admitting, via the one or more processors, a candidate word associated with the input text, from the extended lexicon to the core lexicon, upon a first selection of the candidate word by a user, to create an augmented core lexicon. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product having program codes stored on a computer-readable storage device that, when executed by a computing device, causes the computing device to recognize an input signal entered via a user input interface, the program codes comprising:
-
a core lexicon comprising commonly used words, wherein each of the commonly used words was selected for the core lexicon based on an associated frequency of use value for each word being above a pre-determined threshold, and wherein the frequency of use values are not based on candidate selections by the user; an extended lexicon comprising at least one word not contained in the core lexicon; a program code that, when executed by the computing device, causes the computing device to recognize words associated with the input signal; a program code that, when executed by the computing device, causes the computing device to output an output word associated with the input signal from the core lexicon; and a program code that, when executed by the computing device, causes the computing device to admit a candidate word associated with the input signal, from the extended lexicon to the core lexicon, upon a first selection of the candidate word by the user, to create an augmented core lexicon. - View Dependent Claims (16, 17, 18, 19, 20)
