# PARTYPRESS

Here we maintain the Transformer classifiers trained on the PARTYPRESS database (Erfort et al. 2023). 

The models are fine-tuned in seven languages on texts from nine countries (Austria, Denmark, Germany, Ireland, Netherlands, Poland, Spain, Sweden, UK). 

For the downstream task of classyfing press releases from political parties into 23 unique policy areas, we achieve a performance comparable to expert human coders.



## Description

The PARTYPRESS models have a supervised component. This means, they were fine-tuned using texts labeled by humans. The labels indicate 23 different political issue categories derived from the Comparative Agendas Project (CAP):

| Code | Issue |
|--|-------|
| 1 | Macroeconomics |
| 2 | Civil Rights |
| 3 | Health |
| 4 | Agriculture |
| 5 | Labor |
| 6 | Education |
| 7 | Environment |
| 8 | Energy |
| 9 | Immigration |
| 10 | Transportation |
| 12 | Law and Crime |
| 13 | Social Welfare |
| 14 | Housing |
| 15 | Domestic Commerce |
| 16 | Defense |
| 17 | Technology |
| 18 | Foreign Trade |
| 19.1 | International Affairs |
| 19.2 | European Union |
| 20 | Government Operations |
| 23 | Culture |
| 98 | Non-thematic |
| 99 | Other |

## Variations

There are both monolingual models for each of the countries covered by the PARTYPRESS database, and a multilingual model trained press releases from all countries. The models can be easily extended to other languages, country contexts, or time periods by fine-tuning it with minimal additional labeled texts.

## Intended uses & limitations

The main use of the model is for text classification of press releases from political parties. It may also be useful for other political texts.

The classification can then be used to measure which issues parties are discussing in their communication.
