We are pleased to announce the fourth edition of the LSHTC challenge. 
This year's challenge comprises three tracks and is based on two large 
datasets created from the ODP web directory (DMOZ) and Wikipedia. The 
datasets are multi-class, multi-label and hierarchical. The number of 
categories ranges between 13,000 and 325,000 and the number of documents 
between 380,000 and 2,400,000. The tracks of the challenge are organized 
as follows:

1. Very Large Scale Supervised Learning on a large collection from Wikipedia

2. Multi-task learning, based on both DMOZ and Wikipedia category systems

3. Refinement-learning based on a subset of the DMOZ category system

In order to register for the challenge and gain access to the datasets, 
you must have an account at the challenge Web site. Please consult the 
web site (http://lshtc.iit.demokritos.gr/) for more information on this
