['Report', 'E', 'A', '[ITALIC] E∩ [ITALIC] A', '( [ITALIC] E∩ [ITALIC] A)/ [ITALIC] A', '( [ITALIC] E∩ [ITALIC] A)/ [ITALIC] E', 'F-measure']
The expert-3 reiterated the views expressed by expert-1 in stating that the algorithm missed out some safety policy information. He stated that the algorithm performed better than expected in mining automatic casual information. The total number of causal sentences that both expert-3 and algorithm agree on is 40. The average values of Precision, Recall and F-measure are 0.41, 0.67 and 0.51 respectively.
