Knowledge Base Inference for Regular Expression Queries
Table 12:
['[EMPTY]', '[BOLD] Metrics', '[BOLD] UNIT + AVG', '[BOLD] FP + MLP', '[BOLD] MLP + MLP']
We note that for every model (training or non-training), the metrics decrease drastically, sometimes by orders of magnitude, as the complexity of query increases. This was witnessed in evaluation of r+1→r1/r+2→r+1/r+2. Similar trend is exhibited for (r1|r2)→(r1|r2)+. These observations further reinforce the need to further investigate approaches to improve the performance of these queries.
