METHOD AND DEVICE FOR RECOGNIZING AND TAGGING OF PEAKS, INCREASES, OR ABNORMAL OR EXCEPTIONAL VARIATIONS IN THE THROUGHPUT OF A STREAM OF DIGITAL DOCUMENTS

摘要

The invention relates to a method and a device which make it possible to produce an explanatory view of the changes in the throughput of a stream of documents, or to alert an operator by indicating the main subjects of the abnormal variations in said throughput. The device implements a process (1) of recognizing the periods during which the throughput of a stream of documents varies abnormally, a process (2) of morphologically analyzing text, a process (3) of determining, for a given period, the character strings of which the frequencies are the highest for the documents of the period, and a process (4) of building a tag from the strings identified by said process (3). The device can be coupled to an alarm (23) or display (22) system. The method and the device according to the invention are particularly intended for monitoring over social networks.
