Terrorism Dictionary 2014

Standard

After seeing mass media’s strong response to the extremists’ attack against Charlie Hebdo, I started thinking what can I do for this increasingly important topic? One simple work is making a dictionary containing keywords related to terrorism, so the Terrorism Dictionary 2014 is created. This dictionary is made from newswires submitted by the Associated Press and Agence France-Presse in 2014 using the collocation-of-collocation technique.

The following top-30 keywords contain a lot of nasty words, although there is a proper noun as a result of failure of name entity recognition.
