1. A computer-implemented method comprising: selecting, via at least one processing device, each text file from a collection of text files, wherein the collection of text files have an intensity with respect to negative sentiment toward a common issue; performing, for each text file, by the at least one processing device, at least one profile algorithm, each calculating a corresponding profile score for that text file; combining, by the at least one processing device, at least one corresponding profile score of the text files of the collection to produce a signature for the collection of text files including an aggregated profile score for each of the at least one profile algorithm; storing the aggregated profile score of each of the at least one profile algorithm for the collection; performing the at least one profile algorithm with respect to a desired text file to calculate a signature for the desired text file, the signature including a corresponding profile score for each of the at least one profile algorithm performed with respect to the desired text file; and performing a user-configured action when the signature of the collection is within a threshold distance of the signature of the desired text file, the user-configured action being a contacting action.
