System and method for automatic retrieval of example sentences based on weighted edit distance

摘要

A method and computer-readable medium are provided that retrieve example sentences from a collection of sentences. An input query sentence is received, and candidate example sentences for the input query sentence are selected from the collection of sentences using a term frequency-inverse document frequency (TF-IDF) algorithm. The selected candidate example sentences are then re-ranked 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.
