There seems to be a universal rule for (not only) statistical methods in NLP: more data is better data. [1][2]

Translation systems have at their disposal (orders of magnitude) more training data than a person reads in a lifetime[3].

Available Sources of Large Data

Monolingual

Google n-grams, Google book n-grams, Common Crawl + Moses n-grams

Parallel

OPUS

EU

token vs. type

Obtaining More Data

Crowdsourcing
