　　摘要：

　　The controversy about the cause of abnormal death of bee colonies in France is investigated through an extensive textual data analysis of the daily press. A statistical analysis of textual data is performed on the lexicon used by journalists to describe and present associated information. About 1500 articles are treated to assign each one to either one of three different stands about the cause of the abnormal bee deaths: a unifactor cause, namely pesticides are responsible, a multi-factor cause, it is a combination of a series of different factors which is the cause, the cause is not understood. The variations of the respective proportions of articles as a function of years are obtained for a range from 1998 till 2010. The curves exhibit many brutal changes of slopes. The data are then analyzed using the Galam sequential probabilistic model of opinion dynamics to extract the necessary minimum proportions of inflexible on each side to reproduce exactly the data. Those results are unexpected and enlighten the importance and effect of possible lobbying on journalists from involved sides about the issue. Some hints are obtained about the best winning strategy to win a controversy in the public debate.
