DESCRIPTION

Saša Hassan presented recent launches of Machine Translation on the eBay site for various locales, e.g. Russian and Latin American markets, which enables buyers to shop in their native languages and fosters overall cross-border trade. The core MT stack is based on Moses and is embedded in a larger orchestration layer. This presentation is a part of the MosesCore project that encourages the development and usage of open source machine translation tools, notably the Moses statistical MT toolkit. 

MosesCore is supported by the European Commission Grant Number 288487 under the 7th Framework Programme.
