Natural-language processing system

摘要

A natural-language processing system such as a machine-translation system employs a tree structure of increasingly specialized system dictionaries and attaches user dictionaries to individual system dictionaries in the tree, or helps users edit their user dictionaries by displaying lists of unknown words encountered in translations, or uploads processing programs such as translation engines to a dictionary server to make dictionary access more efficient, or combines a source document and a machine translation thereof into a single document in such a way that the reader of the translation can conveniently see the original source text, or automatically converts contact information in a source document to contact information more suitable for inclusion in a machine translation of the document.
