This data set contains English word n-grams and English word/tag/lemma n-grams in the "Environment" (ENV) domain. N-grams are accompanied by their observed frequency counts. The length of the n-grams ranges from unigrams (single words) to five-grams. The data were collected in the context of PANACEA (http://www.panacea-lr.eu), an EU-FP7 Funded Project under Grant Agreement 248064.
The n-gram counts were generated from crawled Web pages that were automatically detected to be in the English language and were automatically classified as relevant to the ENV domain. The ENV domain collection used consisted of approximately 50.5 million tokens. Data collection took place in the summer of 2011.
