OPUS - an open source parallel corpus

OPUS is an attempt to collect translated texts from the web, to convert and align the entire collection, to add linguistic annotation, and to provide the community with a publicly available parallel corpus. OPUS is based on open source products and is also delivered as an open source package. We used several tools to compile the current corpus. (Manual corrections have not been made.)

The OPUS collection is growing! Check this page from time to time to see new data arriving ...
