Recovering Lexically and Semantically Reused Texts

1 code implementation • Joint Conference on Lexical and Computational Semantics 2021 • Ansel MacLaughlin, Shaobin Xu, David A. Smith

In extensive experiments, we study the relative performance of four classes of neural and bag-of-words models on three LTRD tasks {--} detecting plagiarism, modeling journalists{'} use of press releases, and identifying scientists{'} citation of earlier papers.
