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. When the initial information is low (ξ≤0.6), not blocking is seldom (0.83%) optimal.","tracks":[{"project":"LitCovid-sentences","denotations":[{"id":"T205","span":{"begin":0,"end":78},"obj":"Sentence"},{"id":"T206","span":{"begin":79,"end":415},"obj":"Sentence"},{"id":"T207","span":{"begin":416,"end":500},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T205","pred":"source","obj":"LitCovid-sentences"},{"subj":"T206","pred":"source","obj":"LitCovid-sentences"},{"subj":"T207","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-sentences","color":"#93beec","default":true}]}]}}
