Automatic language detection has been performed on the 10045139 labels of the 2015-5-9 snapshot of X. The 983 datasets have been sorted in descending order by the percentage of labels detected as English. The first 50 datasets with at least 100 labels that were confirmed as labeled in English by manual inspection were chosen for the benchmark with two questions for each selected dataset.
The 10045139 labels of the 2015-5-9 snapshot of X are each assigned an estimated language tag by automatic language detection. Each of the 983 datasets is assigned a score s = |number of labels detected as English|/|number of labels|. The benchmark comprises the 50 datasets with the highest score s for which (1) manual inspection confirms the language as English (2) the number of labels in total is at least 100. The benchmark contains two questions for each dataset.
