We present an approach for building multi- document event threads from a large corpus of newswire articles. An event thread is basi- cally a succession of events belonging to the same story. It helps the reader to contextual- ize the information contained in a single arti- cle, by navigating backward or forward in the thread from this article. A specific effort is also made on the detection of reactions to a particular event. In order to build these event threads, we use a cascade of classifiers and other modules, tak- ing advantage of the redundancy of informa- tion in the newswire corpus. We also share interesting comments con- cerning our manual annotation procedure for building a training and testing set1.
