METHOD AND SYSTEM FOR IDENTIFYING AND ANALYZING GENERALLY CONFUSED WORD BY NATURAL LANGUAGE PARSER

摘要

PROBLEM TO BE SOLVED: To perfectly parse a sentence including the words confused with each other by using a list of confused word sets and processing the word encountered in an input sentence to show a speech part that is shown in another word of the same set as the encountered word. SOLUTION: An input/output device 120 of a computer system 100 includes a keyboard 123 and also optionally includes a voice input device 124 and a handwritten input device 125 which are used by a user to indirectly input a natural language text. A parser 131 of a memory 130 identifies and analyzes the words which are generally confused with each other. The parser 131 contains a chart 132 including a parse tree which shows the input text segments and the intermediate parsing results and also contains a table 133 of the generally confused words and the words that can be confused and mapped to the generally confused words (i.e., the intentional words).
