Description
Online-adaptive Moses (Bertoldi, 2014) is an enhanced version of the well-known state-of-the-art SMT Moses Toolkit, which permits the dynamic (on-the-fly) adaptation of its statistical models without the need of their reloading, according to any suggestions coming from users.
Online adaptation is achieved by means of cache-based language and translation models, which reward their content using either a parametrizable time-decaying scoring function or pre-defined constant values. The caches can be populated at any time from input using an xml-based annotation or pre-populated from file.
Online-adaptive Moses has been successfully integrated in adaptive MT server connected to the MateCat Tool; in this way, it adapts to user post-editing, and supports the usage of terminology.
