+
|
| 21 |
+
## Model Description
|
| 22 |
+
|
| 23 |

+
- **Architecture**: T5-Gemma 2 (270M-270M, 540M total parameters)
|
| 26 |
+
- **Training Data**: 77,515 examples from corporate and news documents
|
| 27 |
+
- **Final Eval Loss**: 0.209
|
| 28 |
+
- **Max Input Length**: 4,096 tokens
|
| 29 |
+
- **Max Output Length**: 2,048 tokens
|

+
## Usage
|
| 32 |
+
|
| 33 |
+
### Python
|
| 34 |
+
|
| 35 |
+
```python
|
| 36 |
+
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
|
| 37 |
+
import torch
|
| 38 |
+
|
| 39 |
+
model = AutoModelForSeq2SeqLM.from_pretrained(
|
| 40 |
+
"Corp-o-Rate-Community/statement-extractor",
|
| 41 |
+
torch_dtype=torch.bfloat16,
|
| 42 |
+
trust_remote_code=True,
|
| 43 |
+
)
|
| 44 |
+
tokenizer = AutoTokenizer.from_pretrained(
|
| 45 |
+
"Corp-o-Rate-Community/statement-extractor",
|
| 46 |
+
trust_remote_code=True,
|
| 47 |
+
)
|
| 48 |
+
|
| 49 |
+
text = "Apple Inc. announced a commitment to carbon neutrality by 2030."
|
| 50 |
+
inputs = tokenizer(f"<page>{text}</page>", return_tensors="pt")
|
| 51 |
+
outputs = model.generate(**inputs, max_new_tokens=2048, num_beams=4)
|
| 52 |
+
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
|
| 53 |
+
print(result)
|
| 54 |
+
```
|
| 55 |
+
|
| 56 |
+
### Input Format
|
| 57 |
+
|
| 58 |
+
Wrap your text in `<page>` tags:
|
| 59 |
+
|
| 60 |
+
```
|
| 61 |
+
<page>Your text here...</page>
|
| 62 |
+
```
|
| 63 |
+
|
| 64 |
+
### Output Format
|
| 65 |
+
|
| 66 |
+
The model outputs XML with extracted statements:
|
| 67 |
+
|
| 68 |
+
```xml
|
| 69 |
+
<statements>
|
| 70 |
+
<stmt>
|
| 71 |
+
<subject type="ORG">Apple Inc.</subject>
|
| 72 |
+
<object type="EVENT">carbon neutrality by 2030</object>
|
| 73 |
+
<predicate>committed to</predicate>
|
| 74 |
+
<text>Apple Inc. committed to achieving carbon neutrality by 2030.</text>
|
| 75 |
+
</stmt>
|
| 76 |
+
</statements>
|
| 77 |
+
```
