Abstract
Online platform has given rise to a problem, “Fragmentation of Public Sphere (Öffentlichkeit) based on using Big Data”.
Such Fragmentation means that citizens are forced to get specific information controlled by Big Data, and then a functional disorder for deliberative democracy accrues because they take part in public sphere.
In other words, a precondition for deliberative democracy is an image of autonomous human; they can see, hear and think about diverse idea.
The author of this article raises a question about this image, which is just a fiction for democracy. The author has presumed that these citizens can acquire only “possibility to insist an idea by themselves immediately” in new public sphere on online platform.
In conclusion, the article shows the issue of the suitability to separate Big Data from a market mechanism to avoid Fragmentation of public sphere.
