Translation Process
In interlingual machine translation systems, there are two monolingual components: the analysis of the source language and the interlingual, and the generation of the interlingua and the target language. It is however necessary to distinguish between interlingual systems using only syntactic methods (for example the systems developed in the 1970s at the universities of Grenoble and Texas) and those based on artificial intelligence (from 1987 in Japan and the research at the universities of Southern California and Carnegie Mellon). The first type of system corresponds to that outlined in Figure 1. while the other types would be approximated by the diagram in Figure 4.
The following resources are necessary to an interlingual machine translation system:
- Dictionaries (or lexicons) for analysis and generation (specific to the domain and the languages involved).
- A conceptual lexicon (specific to the domain), which is the knowledge base about events and entities known in the domain.
- A set of projection rules (specific to the domain and the languages).
- Grammars for the analysis and generation of the languages involved.
One of the problems of knowledge-based machine translation systems is that it becomes impossible to create databases for domains larger than very specific areas. Another is that processing these databases is very computationally expensive.

Famous quotes containing the words translation and/or process:
“Translation is the paradigm, the exemplar of all writing.... It is translation that demonstrates most vividly the yearning for transformation that underlies every act involving speech, that supremely human gift.”
—Harry Mathews (b. 1930)
“A designer who is not also a couturier, who hasn’t learned the most refined mysteries of physically creating his models, is like a sculptor who gives his drawings to another man, an artisan, to accomplish. For him the truncated process of creating will always be an interrupted act of love, and his style will bear the shame of it, the impoverishment.”
—Yves Saint Laurent (b. 1936)
