In SIGIL: Data Sets and Utility Functions for the 'SIGIL' Course

Description

This data set contains bigrams of adjacent word forms from the Brown corpus of written American English (Francis \& Kucera 1964). Co-occurrence frequencies are specified in the form of an observed contingency table, using the notation suggested by Evert (2008).

Only bigrams that occur at least 5 times in the corpus are included.
