Method and apparatus for generating normalized representations of strings

摘要

A method generates normalized representations of strings, in particular sentences. The method, which can be used for translation, receives an input string. The input string is subjected to a first operation out of a plurality of operating functions for linguistically processing the input string to generate a first normalized representation of the input string that includes linguistic information. The first normalized representation is then subjected to a second operation for replacing linguistic information in the first normalized representation by abstract variables and to generate a second normalized representation.
