Abstract

A computer implemented system and method utilizing rules instantiated in objects of an object-oriented operating system to transliterate text as it is input into a computer is disclosed. A number of transliterator objects are created in the storage of the computer, each one of the transliterator objects include transliteration rules arranged in the storage in a preferred order. Each of the transliteration rules contain a first language character string, a second language character string, and logic for comparing the first language character string in each of the transliteration rules to a text string that is entered into a computer to determine a subset of transliteration rules which match the entered text string. The entered text is displayed on a computer display as it is input into a computer and a particular one of the plurality of transliterator objects' logic is utilized in response to the preferred order for selecting one of the subset of transliteration rules and applying it to the first text string to display the second language character string of the selected transliteration rule on the display.

Claims24

Dependent claims

A computer system for transliterating a first text string containing characters from a first language into a second text string containing characters from a second language as it is input to the computer, the system comprising;

(a) a storage;
(b) means for creating a plurality of transliterator objects, each of the plurality of transliterator objects having a plurality of transliteration rules arranged in the storage in a preferred order, each of the plurality of transliteration rules having a first language character string and a second language character string, the transliterator object further having an object method for comparing the first language character string in each of the transliteration rules to the first text string to determine a subset of transliteration rules which exhibit a match;
(c) a display for displaying text as it is entered into a computer;
(d) means responsive to the first text string for selecting one of the plurality of transliterator objects;
(e) means responsive to the first language characters in the first text string for calling the object method in the selected transliterator object;
and
(f) means responsive to the preferred order for selecting one of the subset of transliteration rules to the first text string and displaying the second language character string of the selected transliteration rule on the display;
wherein each of the plurality of transliterator objects comprises a method for displaying a transliterator icon representing the transliterator object on the display and the means for selecting one of the plurality of transliterator objects comprises means responsive to a selection of a displayed transliterator icon for selecting a corresponding transliterator object.

A method for transliterating a first text string containing characters from a first language into a second text string containing characters from a second language in a computer system having a storage and a display as it is input to a computer, the method comprising the steps of:

(a) creating a plurality of transliterator objects, each of the plurality of transliterator objects having a plurality of transliteration rules arranged in the storage in a preferred order for converting first language character strings into second language character strings and an object method for comparing the first language character string in each of the transliteration rules to the first text string to determine a subset of transliteration rules which exhibit a match;
(b) selecting one of the plurality of transliterator objects in response to the first text string as it is entered into the computer;
(c) calling the object method in the selected transliterator object in response to the first language characters in the first text string;
and
(d) selecting one of the subset of transliteration rules and applying the selected transliteration rule to the first text string and displaying the second language character string of the selected transliteration rule on the display;
wherein each of the plurality of transliterator objects comprises a method for displaying a transliterator icon representing the transliterator object on the display and step (b) comprises the step of selecting displayed transliterator icon.
