This interface provides on-line access to JaEn an open-source, deep machine translation system using the the LOGON machine translation architecture. Driving a rich cascade of computational grammars and specialized processing tools, you can input one Japanese sentence at a time, subsequently translate it to English in a stepwise fashion, and inspect intermediate results at varying levels of detail.

Translation proceeds in a pipelined fashion:

The meaning of the text is analyzed an abstract, logical-form semantics (using Minimal Recursion Semantics; MRS); which is subsequently transferred into a target-language semantic form; which in turn is used for full, grammar-based generation of the English system output.

The approach capitalizes on translation quality and precision, rather than on broadest possible coverage or robustness. At its current development stage, the system only has access to a limited vocabulary (especially in transfer). Therefore, choose your input carefully and inspect intermediate results (the probably most interesting aspect of the demonstration) with great care for details. Clicking the Sample button will activate a random selection of Japanese input sentences.
