1. A computer-implemented method for ranking-based information processing, said method comprising the steps of: integrating information from at least one source, to obtain integrated information; mapping said integrated information to at least one application; ranking said integrated information based on said mapping and on ranking criteria from a knowledge base; processing said integrated information, based on said ranking, to obtain processed integrated information; extracting process knowledge from a plurality of process knowledge sources; obtaining ranking criteria for said knowledge base, based at least on said process knowledge; and formatting said integrated information for display; wherein: in said integrating step, said information is from a plurality of heterogeneous sources, and wherein said integrating step comprises integrating said information from said plurality of heterogeneous sources, to obtain said integrated information, said integrated information comprising warranty claims for automotive repair with an identification of corresponding failed parts; said obtaining of said ranking criteria comprises: obtaining a domain selection, said domain selection comprising automotive quality control; obtaining a decision whether to employ a built-in ranking function; and responsive to said decision being affirmative, obtaining a selection of said ranking function from a list, said list being related to said domain selection; said ranking step comprises: normalizing event data to obtain normalized event data; ranking said normalized event data to obtain ranked normalized event data, said ranking of said normalized event data in turn comprising: during a given day, for each of a plurality of said warranty claims, increasing total cost, labor hours, and total number of failures for an appropriate one of said corresponding failed parts; and ranking importance of said corresponding failed parts based on the equation Si = C Max ⁢ { C } + L Max ⁢ { L } + N Max ⁢ { N } where: C is total repair cost of part i; L is total labor hours for repairing part i, and N is total number of failures of part i; said ranking further comprises updating a stored representation in a computer memory, said stored representation representing failure of said failed parts, said failed parts being tangible physical items; and sorting said ranked normalized event data to obtain said integrated information for said processing.
