IMoJIE: Iterative Memory-Based Joint Open Information Extraction
Table 7: Measuring redundancy of extractions. MNO stands for Mean Number of Occurrences. IOU stands for Intersection over Union.
['[BOLD] Extractions', '[BOLD] Metric MNO', '[BOLD] Metric IOU', '[BOLD] Metric #Tuples']
These measures were calculated after removing stop words from tuples. Higher value of these measures suggest higher redundancy among the extractions. Interestingly, IMoJIE has a lower redundancy than even the gold triples; this is due to imperfect recall.
