EUR-Lex Dataset

The EUR-Lex text collection is a collection of documents about European Union law. It contains many different types of documents, including treaties, legislation, case-law and legislative proposals, which are indexed according to several orthogonal categorization schemes to allow for multiple search facilities. The most important categorization is provided by the EUROVOC descriptors, which form a topic hierarchy with almost 4000 categories regarding different aspects of European law.

This document collection provides an excellent opportunity to study text classification techniques for several reasons:

  • it contains multiple classifications of the same documents, making it possible to analyze the effects of different classification properties using the same underlying reference data without resorting to artificial or manipulated classifications,
  • the overwhelming number of produced documents make the legal domain a very attractive field for employing supportive automated solutions and therefore a machine learning scenario in step with actual practice,
  • the documents are available in several European languages and are hence very interesting e.g. for the wide field of multi- and cross-lingual text classification,
  • and, finally, the data is freely accessible (at

The database constitutes a very challenging multilabel scenario due to the high number of possible labels (up to 4000). A first step towards analyzing this database was done by applying multilabel classification techniques on three of its categorization schemes in the following work:
