Method and system for translating sentences between langauges

A method of representing a meaning of a source sentence in a source language, the method comprising:

• obtaining a language-independent semantic structure to represent the meaning of the source sentence;
• synthesizing a syntactic structure of an output sentence from the language-independent semantic structure using information which includes:
• lexical descriptions, semantic descriptions, syntactic descriptions, and morphological descriptions of an output language;
• and
• constructing a representation of the output sentence in a computer memory to represent the meaning of the source sentence in the output language.

A method of generating a sentence in an output language, the method comprising:

• creating a representation of a language-independent semantic structure of the sentence;
• performing a lexical selection on the representation of the language-independent semantic structure of the sentence using lexical descriptions and semantic descriptions in the output language;
• building a syntactic structure of the output sentence from the representation of the language-independent semantic structure using syntactic descriptions and morphological descriptions of the output language;
• performing a morphological synthesis on the syntactic structure of the output sentence using morphological descriptions of the output language;
• and
• constructing, in a memory of a computer device, a representation of the sentence in the output language.

A method of generating a sentence in an output language from a language-independent semantic structure, the method comprising:

• storing a representation of the language-independent semantic structure in a memory of a computing device;
• performing a lexical selection on the language-independent semantic structure of the sentence using lexical descriptions of the output language and semantic descriptions;
• building a syntactic structure of the output sentence in the output language from the language-independent semantic structure using syntactic descriptions and lexical descriptions of the output language;
• determining a linear order and restoring movements on the syntactic structure of the output sentence in the output language;
• performing a morphological synthesis on the syntactic structure of the output sentence in the output language using morphological descriptions of the output language;
• and
• constructing a representation of the sentence in the output language.

A computer readable medium comprising instructions for causing a computing system to carry out steps comprising:

• performing a lexical selection on a representation of a language-independent semantic structure related to a sentence using lexical descriptions and semantic descriptions in the output language;
• building a surface structure of an output sentence in the output language from the representation of the language-independent semantic structure using syntactic descriptions and lexical descriptions of the output language;
• performing a morphological synthesis on the surface structure of the output sentence in the output language using morphological descriptions of the output language;
• and
• constructing a representation of the sentence in the output language.

A computer readable medium comprising instructions for causing a computing system to carry out steps for translating a sentence from a source language into an output language, comprising:

• analyzing a representation of a language-independent semantic structure for the sentence;
• performing a lexical selection on the representation of the language-independent semantic structure of the sentence using lexical descriptions and semantic descriptions in the output language;
• building a representation of a surface structure of the output sentence in the output language from the representation of the language-independent semantic structure using syntactic descriptions and lexical descriptions of the output language;
• determining a linear order and restoring movements on the syntactic structure of the output sentence in the output language;
• performing a morphological synthesis on the surface structure of the output sentence in the output language using morphological descriptions of the output language;
• and
• constructing a representation of the sentence in the output language.
