News tracking and sorting
Research Project Between UN Global Pulse + French Consortium
The French Consortium tracked emerging news trends online and analyzed how Francophone
media reported on food security issues over the past 8 years, using the following method:
First they identified a set of key words and phrases related to food security.
They then retrieved 20,000 related articles published between 2004 and 2011. The
contents of these articles were analyzed and organized in thematic clusters, which can be traced back to specific news articles or aggregated in a big picture representation.
This allowed them not only to track these issues over time, but also to show their location.
For example, at the end of the video, you can see how the global economic crisis unfolded. You can see that as it gained momentum, coverage shifted from a focus on humanitarian issues to food price volatility.
Then it changed to social unrest. Interestingly, children’s vulnerability has been a topic of interest throughout the crisis.
It is believed that this will help researchers + media officers understand the impact of news and alert people when certain topics are of importance.
Information retrieval and tracking becomes easier when computers are able to assist in aggregation and presentation of information
