This study aims to analyze the co-authorship network in Gastroenterology research, focusing on publications from 2000 to 2023, to understand the collaborative relationships among researchers and identify key contributors in the field.
Using data from the Web of Science (WoS), I examined 18,855 Gastroenterology-related articles published between 2000 and 2023. The analysis was conducted using Python within the PyCharm environment. I assessed the network at both macro and micro levels. Macro-level indicators included network density, clustering coefficient, components, and average path length. Micro-level indicators included degree centrality, closeness centrality, and betweenness centrality, which helped identify influential researchers and research groups.
The analysis revealed an evolution from a fragmented and sparsely connected network in the early 2000s to a more interconnected structure in recent years. Despite the overall increase in network density and clustering, full integration was not achieved, with many researchers remaining in isolated clusters. Key researchers such as Gasbarrini G., Vandenplas Y., and Hassan C. were identified as central figures within the network, playing crucial roles in fostering collaboration.
The study highlights the ongoing development of collaborative networks in Gastroenterology research, identifying influential researchers and groups that drive advancements in the field. The findings provide valuable insights for enhancing future research collaborations, particularly in areas where Japan excels, such as endoscopic technology.
本研究旨在分析胃肠病学研究中的合作作者网络，重点关注2000年至2023年的出版物，以了解研究人员之间的合作关系，并确定该领域的关键贡献者。
利用科学网（WoS）的数据，我研究了2000年至2023年发表的18855篇与胃肠病学相关的文章。分析是在PyCharm环境中使用Python进行的。我在宏观和微观层面评估了该网络。宏观层面的指标包括网络密度、聚类系数、组件和平均路径长度。微观层面的指标包括度中心性、接近中心性和中介中心性，这些指标有助于识别有影响力的研究人员和研究团队。
分析表明，从21世纪初的分散且连接稀疏的网络发展到近年来更加相互连接的结构。尽管网络密度和聚类总体上有所增加，但尚未实现完全整合，许多研究人员仍处于孤立的集群中。Gasbarrini G.、Vandenplas Y.和Hassan C.等关键研究人员被确定为网络中的核心人物，在促进合作方面发挥着关键作用。
该研究突出了胃肠病学研究中合作网络的持续发展，识别了推动该领域进步的有影响力的研究人员和团队。研究结果为加强未来的研究合作提供了有价值的见解，特别是在日本擅长的领域，如内镜技术。
