syn-nomos/EUR_Lex_Sum

NOMOSEURLex_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

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
