20. The system of claim 1 , wherein: the translation server comprises: at least one translation front end operable to divide the source text into a plurality of segments in the source language, a plurality of segment translation servers, each segment translation server operable to obtain at least a portion of the obtained machine translation resource data and to translate a segment in the source language into the target language, and a load balancing module operable to assign the segments to one or more of the segment translation servers for translation based on translation load at the segment translation servers, the load balancing module operable to direct translated segments to the translation front end.

The system of claim 20 , further comprising: a translation cache storing translations of, at least, tokens and segments each comprising a combination of tokens, from the source language to the target language, and wherein either the translation front end or the load balancing module, is operable to look up the translation cache for a translation of a segment before directing the segment to segment translation servers, and the load balancing module is further operable to select each segment, that does not have a corresponding translation in the translation cache, to be sent to the segment translation servers for translation.
