# xlm-roberta-large-german-media-cap-v3 |
|
## Model description |
|
An `xlm-roberta-large` model finetuned on multilingual training data containing texts of the `media` domain labelled with [major topic codes](https://www.comparativeagendas.net/pages/master-codebook) from the [Comparative Agendas Project](https://www.comparativeagendas.net/). |
|
|
|
## How to use the model |
|
|
|
```python |
|
from transformers import AutoTokenizer, pipeline |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("xlm-roberta-large") |
|
pipe = pipeline( |
|
model="poltextlab/xlm-roberta-large-german-media-cap-v3", |
|
task="text-classification", |
|
tokenizer=tokenizer, |
|
use_fast=False, |
|
token="<your_hf_read_only_token>" |
|
) |
|
|
|
text = "We will place an immediate 6-month halt on the finance driven closure of beds and wards, and set up an independent audit of needs and facilities." |
|
pipe(text) |
|
``` |
|
|
|
### Gated access |
|
Due to the gated access, you must pass the `token` parameter when loading the model. In earlier versions of the Transformers package, you may need to use the `use_auth_token` parameter instead. |
|
|
|
## Model performance |
|
The model was evaluated on a test set of 1203 examples (10% of the available data).<br> |
|
Model accuracy is **0.64**. |

## Inference platform |
|
This model is used by the [CAP Babel Machine](https://babel.poltextlab.com), an open-source and free natural language processing tool, designed to simplify and speed up projects for comparative research. |
|
|
|
## Cooperation |
|
Model performance can be significantly improved by extending our training sets. We appreciate every submission of CAP-coded corpora (of any domain and language) at poltextlab{at}poltextlab{dot}com or by using the [CAP Babel Machine](https://babel.poltextlab.com). |
|
|
|
## Debugging and issues |
|
This architecture uses the `sentencepiece` tokenizer. In order to run the model before `transformers==4.27` you need to install it manually. |
|
|
|
If you encounter a `RuntimeError` when loading the model using the `from_pretrained()` method, adding `ignore_mismatched_sizes=True` should solve the issue. |
