BBCSport

This dataset consists of 737 documents from the BBC Sport website, corresponding to sports news articles in five topical areas from 2004-2005. The class labels are divided into five categories: athletics, cricket, football, rugby, and tennis. The datasets have been pre-processed using the Porter stemming algorithm, stop-word removal, and filtering out terms with low frequency (count < 3). The files in the archives include: *.mtx (original term frequencies stored in a sparse data matrix in Matrix Market format), *.terms (list of content-bearing terms in the corpus, each line corresponding to a row of the sparse data matrix), *.docs (list of document identifiers, each line corresponding to a column of the sparse data matrix), *.classes (assignment of documents to natural classes, each line corresponding to a document), and *.urls (links to original articles, where appropriate).
