The current status of example based machine translation also reveals, however, the possible constraints of this approach. So far there is no publicly available machine translation system purely based on the example-based approach, except a few on a limited scale for research purposes. Most systems exhibit a certain degree of hybridity with other machine translation approaches. (On the other hand, example-based method has also been widely applied in other machine translation paradigms.) From a practical perspective, it is perhaps more pragmatic to focus on how the strength of example-based method can be adequately utilized, together with other available methods, to tackle various kinds of translation problems
