1. A method for producing a measurement of an effect of a first topic on an aggregate of numerical information related to a set of evaluations of a specific product, comprising: determining, by a first computer system, a subset of the set of the evaluations, the subset defined by inclusion of textual information about the first topic, the set being stored in records in an electronic database, the specific product being at least one of a good, a service, or an application software product; determining, by the first computer system, an aggregate of the numerical information related to the subset; calculating, by the first computer system and based on the aggregate of the numerical information related to the subset, the measurement of the effect of the first topic on the aggregate of the numerical information related to the set; and including, by the first computer system, the measurement in a file to be transmitted to a second computer system to be used to control operations performed by the second computer system to produce a modification to the specific product; identifying a pattern included in the textual information of the evaluations included in the set of the evaluations, the pattern being a pattern in parts of speech, the pattern including a noun and an adjective; calculating a count of a number of occurrences of the noun in the pattern in the set of the evaluations; assigning a numerical value to the adjective in the pattern, the numerical value related to a strength of an opinion associated with the adjective; calculating a product of the count of the numerical occurrences of the noun in the pattern multiplied by a first weight multiplied by the numerical value assigned to the adjective in the pattern multiplied by a second weight; determining whether an absolute value of the product is greater than a threshold; and responsive to determining that the absolute value of the product is greater than the threshold, identifying the noun in the pattern as the first topic.

The method of claim 1 , wherein the determining the aggregate of the numerical information related to the subset comprises: obtaining, from the records for the subset, the numerical information related to the subset; and calculating an average of the numerical information related to the subset.
