Abstract:
A method of language processing for use within a process for machine-translating a document from a source language to at least one target language, comprising the steps:(1) parsing said document using grammar rules specific to said source language to derive a source language-specific semantic graph; (2) applying to a semantic graph, initially said source language-specific semantic graph derived by step (1), a plurality of abstraction rules in sequence until a source language-specific subgraph thereof is detected which meets the requirements of a said abstraction rule; (3) in response to that detection of such a subgraph, modifying the semantic graph in which that subgraph was detected by replacing that subgraph by an abstracted subgraph specified by the said abstraction rule; (4) performing step (2) in respect of the modified semantic graph produced by step (3); and (5) cyclically repeating steps (2), (3) and (4) in respect of respective modified semantic graphs until step (2) fails to detect a said source language-specific subgraph, and thereupon deeming the current semantic graph to be language independent.
