You will have to think about what you are doing. As Duncan said, you need "counts of pairs of words" or, more precisely, of co-occurrence. But co-occurrence within what? Adjacent? Within the same sentence? Within the same paragraph? Within the same chapter? Within the same document (if your corpus incorporates several documents)? Within documents by the same author? If so, then is there an additional classification by individual document? Etc., etc., etc. In short, what is the structure of your corpus, and how do you wish this to be represented in the Burt table? Hoping this helps to move you forward, Ted. > On Mar 29, 2009, at 2:00 PM, Duncan Murdoch wrote: > >> On 29/03/2009 7:02 AM, Joan-Josep Vallbé wrote: >>> Dear all, >>> I have a word frequency list from a corpus (say, in .csv), where >>> the first column is a word and the second is the occurrence >>> frequency of that word in the corpus.
