The Influence Between NLP and Other Fields This paper aims to quantify the degree of influence between 23 fields of study and NLP. The cross-field engagement of NLP has declined from 0.58 in 1980 to 0.31 in 2022. What does this mean? It means that NLP papers are drawing proportionally less from other fields over time and engaging less with outside literature. The study also finds that NLP citations are dominated by CS which accounts for over 80% of citations with emphasis on AI, ML, and information retrieval. Overall, NLP is growing more insular -- higher growth of intra-field citation and a decline in multidisciplinary works. Quote from the paper: "Contributions from non-CS fields like linguistics and sociology have diminished over time." Quote from the blog: "We see that linguistics, mathematics, psychology, and sociology are the most cited non-CS fields by NLP. They are also the non-CS fields that cite NLP the most, albeit the order for mathematics and psychology is swapped." Lots of other great insights in the paper. The authors also wrote a nice blog post on it. Check it out below.
