A paper typically refers to an article that conducts research in various academic fields and describes scholarly achievements, abbreviated as "thesis" or "dissertation." It serves both as a means to explore issues through academic inquiry and as a tool to communicate research outcomes for scholarly exchange. Publication of papers is a critical activity for researchers and scholars to share findings and advance academic progress. In today's academic landscape, publishing papers has become one of the fundamental metrics for evaluating the achievements of researchers or scholars.

Meanwhile, academic articles undergo peer review, and those published in academic journals generally pertain to specific disciplines. Academic journals showcase advancements in research fields and serve as platforms for public dissemination. These journals are categorized into general journals, special issues, core journals, and international English-language journals. Internationally recognized academic journal publishers include RELX Group, Springer-Verlag, Wiley & Sons Inc, SAGE Publishing, IEEE, and MDPI.
