Overview

Rank filters are post-process filters which can filter, enhance, or modify the results of the PageRank algorithm. A common use case is to collapse highly ranked tokens which are found to be adjacent in the original text. Other filters might modify the PageRank scores with some sort of external modifier. Another use might be to remove collapsed tokens which are not desired (since token filters only operate on a single, non-collapsed token).

Rank filters are applied as a chain, so care should be taken to use them in the desired order.
