SYSTEM AND METHOD FOR AUTOMATIC RETRIEVAL OF EXAMPLE SENTENCE BASED ON WEIGHTED EDITING DISTANCE

摘要

PPROBLEM TO BE SOLVED: To provide a method for retrieving an example sentence from collection of sentences and a computer readable medium. PSOLUTION: An input query sentence is received (305) and candidate example sentences to the input query sentence are selected (310, 315) from collection of sentences by using term-frequency- inverse document frequency (TF-IDF) algorithm. Then, the selected candidate example sentences are re-ranked (320, 325) based upon weighted editing distances between the selected candidate example sentences and the input query sentence. A system which implements the method is also provided. PCOPYRIGHT: (C)2004,JPO
