Censorship as / and Social Good
Figure 1 . Distribution of topics containing “ Mark Twain .”
January 3 divides across two topics ; and , January 2 is associated with a single topic . Looking more closely at an individual day reveals , for instance , that January 1 divides into three topics : Topic 1 describes 21.5 % of the coverage ; Topic3 is associated with 78.4 % of the coverage ; and Topic 8 accounts for < 1 %. January 2 is described by Topic10 ; and January 3 coverage is 88 % Topic21 and 12 % Topic13 .
Turtles in my model select topics of conversation in accordance with my topic modeling data . The first cycle of the model coincides with the distribution of topics present on January 1 , 1906 : 21 % of turtles take up an interest in Topic 1 ; 78 % of turtles are ready to discuss Topic 3 ; and 1 % of turtles in the environment are ready to converse about Topic 8 . Turtles also adopt a color associated with their particular topic of interest so that the distribution of topics through the space may be noted by looking at an overview of the model world .
New lists of available topics are introduced into the environment every tick .
The rate at which turtles take up these new topics is controlled by a percent-activereaders slider , which determines the number of turtles in the environment that draw their topic of conversation directly from the list of active conversations available at every tick of the model . Turtles identified by the percent-active-readers slider may be thought of as people that take an active interest in and keep up with news coverage every day . At 100 %, every turtle in the model draws its topic of conversation from the current news coverage made available with each tick of the model . At 0 %, turtles take up current news topics only when they are unsuccessful in an attempt to discuss their current topic of conversation .
