This paper reports on the Large Scale Hierarchical Classification workshop (http://kmi.open.ac.uk/events/ecir2010/workshops-tutorials), held in conjunction with the European Conference on Information Retrieval (ECIR) 2010. The workshop was associated with the PASCAL 2 Large-Scale Hierarchical Text Classification Challenge (http://lshtc.iit.demokritos.gr), which took place in 2009. We first provide information about the challenge, presenting the data used, the tasks and the evaluation measures and then we provide an overview of the approaches proposed by the participants of the workshop, together with a summary of the results of the challenge.
