METHOD AND SYSTEM TO ANALYZE, TRANSFER AND GENERATE LANGUAGE EXPRESSIONS USING COMPILED INSTRUCTIONS TO MANIPULATE LINGUISTIC STRUCTURES

摘要

A natural language translation system contains language-neutral modules for syntactic analysis (216), transfer (222), and morphological and syntactical generation (228) of feature structures for an input expression in a source (202) and a target language (230). The language-neutral modules are driven by language-specific grammars (212, 218, 224) to translate between the specified languages so that no knowledge about the languages need be incorporated into the modules themselves. The modules interface with the grammar rules in the form of compiled grammar programming language statements that perform the required manipulation of the feature sturctures. Because the modules are language-neutral, the system is readily adaptable to new languages simply by providing a grammar for the new language. Multiple copies of each module, each interfacing with a different natural language grammar, enables simultaneous translation of multiple languages in the same system.
