Table 1 Comparison between different RE methods
Method type | Characteristics | Advantages and Disadvantages |
|---|---|---|
Pipeline | Separate subtasks | Propagation error and reductant entities prediction |
Parameter sharing | Merge subtasks | Void propagation error but cause computing resources problem |
Sequence tagging | Merge subtasks | Reduce resources waste but need high-quality data |
Sequence tagging and active learning | Merge subtasks and active learning | High-quality data problem is alleviated |
