MACHINE TRANSLATION AND TELECOMMUNICATIONS SYSTEM USING USER ID DATA TO SELECT DICTIONARIES

A machine translation and telecommunications system includes a machine translation engine for translation of input text from a source language to a target language, a dictionary database including a core dictionary and a plurality of sublanguage (domain) dictionaries usable for translation from a source to a target language, a receiving interface for receiving text input from any of a plurality of users, each text input being accompanied by control information including user ID data indicative of one or more sublanguages preferred by a particular user, an output interface, and a dictionary control module coupled to the receiving interface responsive to the user ID data indicative of a sublanguage preference of a particular user for selecting a corresponding sublanguage dictionary of the dictionary database to be used by the machine translation engine along with the core dictionary for performing translation of the particular user's text input. User dictionaries can be maintained and selected to enhance translation accuracy in the same manner. The dictionary database encompassing core, sublanguage (domain), and user dictionaries is cumulated for greater capability over time through the use of dictionary maintenance utilities for updating the dictionaries.
