In addition, they mostly have the same collocation words that can be captured in a window of size two. Johannes Hellrich investigated this problem both empirically and theoretically and found some variants of SVD-based algorithms to be unaffected. Any filtering functions that are applied reduce the size of these two FreqDists by eliminating any words that don't pass the filter.
