We design a structured **tagging strategy** to directly fine-tune ERNIE, through which multiple, overlapped SPOs can be extracted in **a single pass**.
The InfoExtractor 2.0 system is simple yet effective, achieving 0.554 F1 on the DuIE 2.0 demo data and 0.848 F1 on DuIE 1.0.
The hyperparameters are simply set to: BATCH_SIZE=16, LEARNING_RATE=2e-5, and EPOCH=10 (without tuning).

### Tagging Strategy
Our tagging strategy is designed to discover multiple, overlapped SPOs in the DuIE 2.0 task.
Based on the classic 'BIO' tagging scheme, we assign tags (also known as labels) to each token to indicate its position in an entity span.

For **complex relations** in the DuIE 2.0 task, we simply treat affiliated objects as independent instances (SPOs) which share the same subject.
Anything else besides the tagging strategy is implemented in the most straightforward way. The model input is:
<CLS>*input text*<SEP>, and the final hidden states are directly projected into classification probabilities.
