|3 Sources Dataset|
We provide here a new multi-view text dataset, collected from three well-known online news sources: BBC, Reuters, and The Guardian. This dataset exhibits a number of common aspects of multi-view problems highlighted previously -- notably that certain stories will not be reported by all three sources (i.e incomplete views), and the related issue that sources vary in their coverage of certain topics (i.e. partially missing patterns).
In total we collected 948 news articles covering 416 distinct news stories from the period February–April 2009. Of these stories, 169 were reported in all three sources, 194 in two sources, and 53 appeared in a single news source. Each story was manually annotated with one or more of the six topical labels: business, entertainment, health, politics, sport, technology. These roughly correspond to the primary section headings used across the three news sources.
This dataset is made available for non-commercial and research purposes only, and is provided in pre-processed matrix format. Note that stemming (Porter algorithm), stop-word removal (stop word list) and low term frequency filtering (count < 3) has already been applied to the data. All rights, including copyright, in the content of the original abstracts are owned by the original authors.
