Creating a word list

Download the corpus from google ngram with:

for a in a b c d e f g h i j k l m n o p q r s t u v w x y z; do
    wget http://storage.googleapis.com/books/ngrams/books/googlebooks-eng-all-1gram-20120701-$a.gz;
done

then you can filter the words like this:

for L in a b c d e f g h i j k l m n o p q r s t u v w x y z; do
    gzcat googlebooks-eng-all-1gram-20120701-$L.gz | python ngram-filter.py > googlebooks-eng-all-1gram-20120701-$L-filtered;
done

To get a list of the top 300 words:

sort -n googlebooks-eng-all-1gram-20120701-*-filtered | tail -n 300

To create the wordlist used by These3Words run:

sort -n googlebooks-eng-all-1gram-20120701-*-filtered | python normalise-words.py | tail -n32768 > google-ngram-list

Check that your list is long enough by counting the lines in google-ngram-list, you need exactly 32768 words
