Question Answering over Knowledge Graphs via Structural Query Patterns
Table 5: Effect of SQP recognition and entity lining
['Method (on dataset)', 'Precision', 'Recall', 'F1-Measure']
Note that the results on LC-QuAD are reported with respect to the performance on constructed structural query patterns. We observe that the improvement gained by qaSQP-CP is subtle. Moreover, we can find that qaSQP-CE performs much better than qaSQP-CP on both QALD-8 and QALD-9. It indicates that the system qaSQP can almost find the correct structural query patterns. Meanwhile, there is still much room to improve the initial entity linking.
