A computing system and method receive a query; separate a plurality of information sources into individual elements of content (EOC); tag each EOC with metadata that indicate source, date, and other relevant information; pattern match each EOC; calculate the respective distance function from every EOC to every other EOC; and output EOC to a set of virtual buffers (404) containing appropriately related EOC less than a given distance value. The method further creates virtual summary buffers (406); then concatenates the EOC in each virtual buffer (404); applies a comparative analysis filter (318) to remove redundant sub-elements; and presents the results as summary digests (408).
