Paradigm Shift in NLP

Welcome to the webpage for "Paradigm Shift in Natural Language Processing". Some resources of the paper are constantly maintained here, such as a full list of papers of paradigm shift, an interactive Sankey diagram to depict the trend of paradigm shift, etc.

What is paradigm shift?

First of all, what is paradigm, and what is paradigm shift?

Paradigm is the general framework to model a class of tasks. For example, sequence labeling (SeqLab) is a popular paradigm to solve named entity recognition (NER). We summarize the mainstream paradigms that are widely used for common NLP tasks as: Class, Matching, SeqLab, MRC, Seq2Seq, Seq2ASeq, (M)LM.

Paradigm shift is a phenomena of solving a task that is usually solved with some paradigm with another paradigm. For example, Li et al. (2020) uses the MRC paradigm to solve NER, which is previously solved with SeqLab, then we can say that the paradigm of NER shifted from SeqLab to MRC.

The figure below shows the observed shift (or transfer) of the seven paradigms in recent years.

Paradigm shift in NLP tasks

We collect the papers of paradigm shift in the table below, which is an extension of the Table 1 in our original paper. This table will be constantly updated.

Trends

To intuitively depict the trend of paradigm shift in NLP, we also draw an interactive Sankey diagram, which is an extension of the Figure 2 in our original paper. Also, this diagram is constantly updated as the table above changed.

Hi, thanks for your greatly insightful survey. I had summarized related papers two months ago which may not be as comprehensive as yours. Sincerely hope it will contribute to this nice repo. For more info please visit NLP-ParadigmShiftingPapers.

Could you reorganize the paper list

hi, sun. Thanks for your insightful survey work for the paradigm shift in NLP. The papers in this repo only have the published year and authors' names. Could you reorganize the paper list to offer more details, e.g. the titles?
