Can a text be attacked? Unwrapping NLP, clashes in meaning, vulnerability and adversarial perturbations


In recent years, Deep Learning has fundamentally changed the landscape of several areas in Artificial Intelligence, including speech, computer vision, pattern recognition, and robotics. Following this trend, recent Natural Language Processing research has increasingly focused on the use of new deep learning methods in multiple practical scenarios. Naturally, with advances NLP new threats have emerged. Looking back to the basics, in Linguistics and Interpretation Theory, word order and syntactic structure have a large impact on sentence meaning. Even small perturbation in word order or a morpheme can completely change interpretation. So, the same logic applies to NLP and DL. Could perturbations, barely perceptible by the human eye, make it even harder to generate text adversarial examples? Is there a defence method against attacks that aim to satisfy all the lexical, grammatical, semantic constraints? Is it possible to overcome the new challenges and prevent attacks by malicious users?
