1. A method for determining changes in the count of news articles related to a subject over a recent time period, the method comprising:
- measuring a count of news articles for the subject produced by a present news source configuration over the recent time period;
determining a reconfiguration factor to account for changes between the present news source configuration and a previous news source configuration, wherein determining the reconfiguration factor includes dividing the frequency of news articles for all subjects of a recent server configuration by the frequency of news articles for all subjects of a previous server configuration;
applying the reconfiguration factor to a count of news articles for the subject for a previous time period to obtain a new count;
comparing the count of news articles for the subject over the recent time period to the new count; and
signaling when the comparison yields a difference greater than a predetermined amount.

25. A system for determining changes in the count of news articles related to a subject over a recent time period, the system comprising:
-
a counter for measuring a count of news articles for the subject produced by a present news source configuration over the recent time period; a comparator for determining a reconfiguration factor to account for changes between the present news source configuration and a previous news source configuration, wherein determining the reconfiguration factor further includes dividing the count of news articles for all subjects over the recent time period by the count of news articles for all subjects over at least one prior time period of equal duration; a processor for applying the reconfiguration factor to a count of news articles for the subject for a previous time period to obtain a new count; a comparator for comparing the count of news articles for the subject over the recent time period against the new count of news articles for the subject for a previous time period; and a report for signaling when the comparison yields a difference greater than predetermined amount.
