This directory contains data sets for Bengali, Hindi, Malayalam, Tamil, Telugu, and Urdu. Each data set was created by taking around 100 Indian-language Wikipedia pages and obtaining four independent translations of each of the sentences in those documents.
The procedure used to create them, along with descriptions of initial experiments, is described in: Constructing Parallel Corpora for Six Indian Languages via Crowdsourcing. 2012. Matt Post, Chris Callison-Burch, and Miles Osborne. Proceedings of the NAACL Workshop for Statistical Machine Translation (WMT).
