wl            - cell array with list of words (>14K)
docname       - cell array names of documents (2486 docs)
authors_names - cell array with authors names.

counts        - n_words x n_docs count matrix 
aw_counts     - n_words x n_authors count matrix
                Words from each document were assigned to each of the
                authors, after dividing by the number of authors of
                that document
