On-going Cooperative Research towards Developing Economy-Oriented Chinese-French SMT Systems with a New SMT Framework

We present an on-going collaborative project pursued by Grenoble University and Xiamen University and aiming at creating instances of a new kind of SMT system using semantics and discourse-related resources. The concrete goal is to develop Chinese-French systems specialized to stock option and economic websites. Since very few Chinese-French bilingual corpora and dictionaries are freely available on Internet, English is used as a “pivot” for constructing the Chinese-French translation equivalents by transitivity. For this, we use a method, proposed by XMU, of probability induction based on topic similarity, which produces C-F translation tables from C-E and E-F translation tables. For getting good C-F parallel corpora, we use a web-based collaborative post-editing system that can trigger the incremental improvement of the MT system by using MT evaluation metrics and extracting the "best part" of the current translation memory.
