T200 0-4 Sentence denotes 3.3.
T201 5-49 Sentence denotes Intervention Dilemma in Blocking Information
T202 50-232 Sentence denotes We assume the government will block any transmission of under-the-blocking-threshold (XB) information between individuals; thus, XB=0 denotes the special case in previous discussion.
T203 233-270 Sentence denotes Other settings are the same as above.
T204 271-359 Sentence denotes In this part, we will discuss the optimal blocking strategies and analyze the mechanism.
T205 360-438 Sentence denotes As shown in Figure 5, the optimal blocking threshold varies from case to case.
T206 439-775 Sentence denotes Overall, a small blocking threshold ([0.1,0.3]) is necessarily (100%) not optimal; a strict blocking threshold (XB≥0.8) is usually (50.41%) optimal, experimental data show a value between 45% and 55% in most external conditions; but 0 is the optimal threshold still in 20.25% of cases, and usually (89.80%) occurs when ξ≥0.8 and XI≤0.7.
T207 776-860 Sentence denotes When the initial information is low (ξ≤0.6), not blocking is seldom (0.83%) optimal.
T208 861-910 Sentence denotes We have our key findings from the above analysis.
T209 911-1161 Sentence denotes First, minor blocking is not an option for government because it is dominated by stricter blocking in a deteriorated or being deteriorated information environment and undermines the efficiency of information dissemination in a benevolent environment.
T210 1162-1435 Sentence denotes Second, in the age of the Internet, information is extremely interconnected and low-quality information is more easily disseminated, thus stricter information blocking might be an option worth considering in the early stages of an outbreak of an unknown infectious disease.
T211 1436-1730 Sentence denotes Finally, if the virus is well-known at the medical level, plus the public has a certain level of health awareness, free spread of information might improve the situation; while, otherwise, as in the case of COVID-19, governments should intervene in the spread of information in social networks.
T212 1731-1869 Sentence denotes From the simulation results, we can see that, in most cases, the optimal strategy will be either highly stringent blocking or free spread.
T213 1870-2029 Sentence denotes Blocking low-quality information not only increases the overall information of the whole population, but causes side effects under certain external conditions.
T214 2030-2090 Sentence denotes Thus, not blocking can be an optimal strategy in some cases.
T215 2091-2179 Sentence denotes In this section, we provide an in-depth analysis of the data and a mechanistic analysis.
T216 2180-2439 Sentence denotes Figure 5b reveals in general the optimal blocking threshold negatively correlates with initial information: as initial information drops from 1 to 0.4, the probability of optimal blocking threshold taking 0 will be 52.07%, 27.27%, 1.65%, and 0%, respectively.
T217 2440-2539 Sentence denotes Figure 5c shows a positive correlation between optimal blocking threshold and individual threshold.
T218 2540-2723 Sentence denotes Governments block information mainly by suppressing less-accurate information, but which, once implemented, will slow down the overall information dissemination in the network anyway.
T219 2724-2829 Sentence denotes Therefore, blocking can neither be too stringent nor too liberal, an optimal one usually lies in between.
T220 2830-2930 Sentence denotes However, mild blocking is necessarily not optimal as it fails to purify the information environment.
T221 2931-3087 Sentence denotes Furthermore, when the virus is well-known (ξ=1), especially when public health awareness is high (XI≤0.3), not blocking dominates most of the time (69.70%).
T222 3088-3299 Sentence denotes While stringent blocking (XB≥0.8) is necessarily not (0%) an optimal strategy because higher-quality information, which helps to slow the spread of the disease with high public health awareness, is also blocked.
T223 3300-3490 Sentence denotes Thus, when both the initial information and the level of public health awareness are at a high level, not blocking is optimal; otherwise, information that would not cause panic might do now.
T224 3491-3634 Sentence denotes In addition, when medical awareness of the virus declines, so does the proportion of valuable information, which necessitates blocking as well.
