Instead of using only the text from the abstracts, like in their research, to make the comparison more fair we used text from the entire documents -just like we did for the rest of our systems.
adhering to their naming convention, the features from their system that we used are: citation-count, venue-citation-count, authorcitation-count, author-h-index, age (# years between report and source), terms-citing, topics, authors, authors-cited-article, and authors-cited-author.
