Further research on Sentimental analysis tools

*Abstract
             
              This week, I did research on the differences between the news headlines and its contents. The aim of this experiment was to find out what kind of similarity or disparity between them can be observed using the Net-tone analysis.


*Method

              For this research, I picked up five articles about immigration from various media sources and divided them into three categories “Positive”, ”Neutral” and “Negative”. In order to make sure that the result is credible enough, I assumed the attitudes per different sides. Specifically speaking, those groups are the views from Pro-immigrant groups, from Normal groups, from Anti-immigrant groups and Corenlp (only for news headlines) which is a software made by Stanford university scientists to evaluate the texts’ sentimental analysis. Also, I compared the attitudes of news headlines with that of their contents.

*Results

“Why is EU struggling with migrants and asylum?”

*Conclusion


              All in all, there were interesting outcomes I could get from this attempt. One of them would be the remarkable similarity in the results of the attitude of “Pro-IMMG” and “Corenlp”. In addition, attitude's change between headlines and contents was also quite noteworthy.
