1. A method for processing messages, said method comprising: identifying, by a processor of a computer system, an action to be subsequently performed on the message; in response to said identifying the action, said processor extracting one or more word objects from the message; said processor deriving a first combination of one or more concepts from the one or more word objects, wherein each concept of the one or more concepts is associated with at least one word object of the one or more word objects, and wherein each word object of the at least one word object is an instance of the associated concept; said processor determining a first interest value associated with the first combination; said processor determining that the first interest value is at least a specified first threshold value; and in response to said determining that the first interest value is at least the specified first threshold value, said processor updating a concept interest dataset, wherein the concept interest dataset prior to being updated comprises a plurality of combinations of at least one concept, wherein each concept of the at least one concept has been derived from a previous processing of messages, and wherein the updated concept interest dataset comprises the first combination and a cumulative interest value that encompasses the first interest value.
4. The method of claim 1 , wherein the plurality of combinations includes the first combination, and wherein the cumulative interest value consists of the first interest value added to a value of the first combination that existed in the concept interest dataset prior to said updating.
