Mining Wikipedia Revision Histories for Improving Sentence Compression - scientific work related to Wikipedia quality published in 2008, written by Elif Yamangil and Rani Nelken.
Overview
A well-recognized limitation of research on supervised sentence compression is the dearth of available training data. Authors propose a new and bountiful resource for such training data, which authors obtain by mining the revision history of Wikipedia for sentence compressions and expansions. Using only a fraction of the available Wikipedia data, authors have collected a training corpus of over 380,000 sentence pairs, two orders of magnitude larger than the standardly used Ziff-Davis corpus. Using this new-found data, authors propose a novel lexicalized noisy channel model for sentence compression, achieving improved results in grammaticality and compression rate criteria with a slight decrease in importance.
