NOMOS_EUR_Lex_Sum is a Greek-language legal text summarization dataset derived from official documents of the EUR-Lex portal.
The dataset focuses on extractive summarization of European Union legislative texts written in Greek and was developed in the context of the +NOMOS project

## Dataset Structure

The dataset follows a hierarchical folder structure based on EUR-Lex thematic categories.

- Top-level folders represent broad policy areas
- Intermediate folders represent subtopics
- Only the final-level folders (leaf folders) contain actual data files

Each leaf folder corresponds to **one EU legal document and its summary**.

### Files inside a leaf folder

Only leaf folders contain the following files:

  #### CELEX file (`<celex_id>.txt`)
  - Full legal text in Greek
  - Filename corresponds to the official CELEX identifier (e.g., `32013R1408.txt`).
  
  #### `summary.txt`
  - Summary of the legal document
  - Written in Greek
