-AG is a collection of more than 1 million news articles. News articles have been
-gathered from more than 2000 news sources by ComeToMyHead in more than 1 year of
-activity. ComeToMyHead is an academic news search engine which has been running
-since July, 2004. The dataset is provided by the academic comunity for research
-purposes in data mining (clustering, classification, etc), information retrieval
-(ranking, search, etc), xml, data compression, data streaming, and any other
-non-commercial activity. For more information, please refer to the link
-http://www.di.unipi.it/~gulli/AG_corpus_of_news_articles.html .

-The AG's news topic classification dataset is constructed by Xiang Zhang
-([email protected]) from the dataset above. It is used as a text
-classification benchmark in the following paper: Xiang Zhang, Junbo Zhao, Yann
