Constructionist approaches aim to account for the full range of facts about language, without assuming that a particular subset of the data is part of a privileged 揷ore? Researchers argue that unusual constructions shed light on more general issues, and serve to illuminate what is required for a complete account of language.展开更多

In this survey, we provide a comprehensive review of PTMs for NLP. We first briefly introduce language representation learning and its research progress. Then we systematically categorize existing PTMs based on a taxonomy from four different perspectives. Next,we describe how to adapt the knowledge of PTMs to downstream tasks. Finally, we outline some potential directions of PTMs for future research. This survey is purposed to be a hands-on guide for understanding, using, and developing PTMs for various NLP tasks.展开更多
