Replication issues in syntax-based aspect extraction for opinion mining
Table 1: Performance comparison for FBA.
['[BOLD] Corpus', '[BOLD] Original  [BOLD] P', '[BOLD] Original  [BOLD] R', '[BOLD] Ours  [BOLD] P', '[BOLD] Ours  [BOLD] R']
We remain unable to replicate the performance reported by the authors and see a big drop for both precision and recall in all the datasets. In our experiments, we noted that the most sensitive parameter was minsup for itemset mining. We also experimented omitting the pruning steps and observed that precision and recall were not too different from the results we obtained with pruning.
