Legal Classification Track

Overview

The purpose of this track is to evaluate methods of document classification on a collection of legal documents.

For this track the standard procedure is used.

Test Collection

The source dataset is the collection of legal collection (2004).

Task Description for Participating Systems

Each participant is granted access to the tarining set, and a set of documents from the collection. The task is to assign topic(s) from the training set to each document from the collection. Valid number of topics per document is from 0 to 5.

The training set is a subset of the categories based on the Kodeks catalog. Documents of the training set are located in legal_training.* archives.

All the documents from the collection must be classified by participants, so for each of these documents must be specified a list of topics (which should be sorted in descending order of confidence).
