Combines two bigram files created by count.pl into a single bigram file.
huge-combine.pl [OPTIONS] COUNT1 COUNT2
combine-count.pl takes two bigram files created by count.pl as input. If COUNT1 and COUNT2 are of unequal sizes, it is strongly recommended that COUNT1 should be the smaller file and COUNT2 should be the lager bigram file.
Each line in files COUNT1, COUNT2 should be formatted as -
word1<>word2<>n11 n1p np1
where word1<>word2 is a bigram, n11 is the joint frequency score of this bigram, n1p is the number of bigrams in which word1 is the first word, while np1 is the number of bigrams having word2 as the second word.
Displays this message.
Displays the version information.
Output displays all bigrams that appear either in COUNT1 (inclusive) or in COUNT2 along with their updated scores. Scores are updated such that -
If a bigram appears in both COUNT1 and COUNT2, their n11 scores are added.
e.g. If COUNT1 contains a bigram word1<>word2<>n11 n1p np1 and COUNT2 has a bigram word1<>word2<>m11 m1p mp1
Then, the new n11 score of bigram word1<>word2 is n11+m11
If the two bigrams belonging to COUNT1 and COUNT2 share a commom first word, their n1p scores are added.
e.g. If COUNT1 contains a bigram word1<>word2<>n11 n1p np1 and if COUNT2 contains a bigram word1<>word3<>m11 m1p mp1
Then, the n1p marginal score of word1 is updated to n1p+m1p
If the two bigrams belonging to COUNT1 and COUNT2 share a commom second word, their np1 scores are added.
e.g. If COUNT1 contains a bigram word1<>word2<>n11 n1p np1 and if COUNT2 contains a bigram word3<>word2<>m11 m1p mp1
Then, the np1 marginal score of word2 is updated to np1+mp1
