 Patents Public Datasets, where for each document there is one gold-standard summary which
 is the patent’s original abstract. One advantage of this dataset is that it does not present
 difficulties inherent to news summarization datasets, where summaries have a flattened discourse
 structure and the summary content arises in the begining of the document.

 dataset, thus, contains 3,000 Single-Documents with two gold-standard summaries each: one
 extractive and one abstractive. The encompassing of extractive gold-standard summaries is
 also an advantage of this particular dataset over others with similar goals, which usually only
 contain abstractive ones.
