Abstract:
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.
