The Patient Information Leaflet (PIL) Corpus

Version 2.0 (31 Mar 2006)

This directory contains the PIL corpus derived from the PIL corpus data. This contains all the documents originally processed, but with some non-PIL documents (such as product lists) and near-duplicates removed. This is the recommended version for research purposes. See the base corpus for the complete original corpus in a similar format. For details of the corpus package as a whole, see the PIL corpus home page.
