A method receives a query; separates a plurality of information sources into individual elements of content (EOC); tags each EOC with metadata that indicate source, date, and other relevant information; pattern matches each EOC; calculates the respective distance function from every EOC to every other EOC; and outputs 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); concatenates the EOC in each virtual buffer (404); applies a comparative analysis filter (318) to remove redundant sub-elements extracts context-preserving EOC, determined based upon a respective degree of corroboration of the context preserving EOC, from each respective concatenated EOC. The method synthesizes the content-preserving EOC extracted from each respective concatenated EOC into summary digests; and presents the results as summary digests (408).
