Abstract

See full text

An input sentence described by a first natural language is sectioned into individual words. Parts of speech corresponding to the individual words are retrieved from a lexical word storage, whereby the input sentence is described by a corresponding string of the parts-of-speech as retrieved. A translation pattern table is previously prepared which defines correspondence between patterns of strings of parts-of-speech for the first natural language and those for a second natural language by which corresponding output sentence is to be described. By referring to the translation pattern table, the string of the parts-of-speech of the input sentence is transformed into a corresponding string of the parts-of-speech for the second natural language. The output sentence described by the second natural language is generated by sequencing target words in accordance with the sequential order of the parts of speech of the string pattern obtained after the transformation.
