Newsweek is using the DayPIs to build an interactive application called the Threat Meter. A user can rate the different issues on the Threat Meter and read negatively opinionated stories (threats!) published by Newsweek and their partners The Washington Post and MSNBC related to the issues.
Once the user has rated the issues, he can see the overall ratings as well as read more about the issues.
The Threat Meter is also available as a widget to put it up on your own blog or facebook profile.
Read more below about the DayPI calls that Newsweek uses to power this application.
The DayPI Search calls used with source filtering power the Threatmeter. The application calls search_getRelatedArticles with three values for the parameter source_whitelist - Newsweek, The Washington Post and MSNBC. The other interesting filtering that Threat Meter does is that it only selects articles that have a negative spin score in the range of -5 to -10. This is what makes the Threat Meter float up the stories that have a "threat" perspective.
