Scientific comparative advantage is measured by using a specialization index (SI) of article citations. The profile data have been published in the literature. However, no such research has been conducted to determine which countries dominate the field of computer science (CS) (subject category [SC]) using the SI. A KIDMAP in the Rasch model has been applied to the display of individual student performance in school. Based on the SI of article citations, we used KIDMAP to determine whether China dominates the field of CS.
The data were derived from published research in the Web of Science, which included 199 countries and 254 subject categories (SC, between 2010 and 2019). A total of 96 SC related to biomedicine were extracted. We examined 7 factors associated with CS using exploratory factor analysis. Based on the SI in CS under the Rasch model, 1-dimensional SCs on CS were displayed on Wright Maps and KIDMAPs. An analysis of the dominance of CS in China was presented on the basis of a scatter plot.
Our findings indicate that (1) CS domains are divided into 2 groups (traditional and advanced domains); (2) no evidence has been found that China dominates CS; based on SI indicators, China was ranked third with --2.62 and 0.79 logits after Taiwan and Slovenia (-(-2.62 and 9.24 logits in Factors 1 and 2) in the period from 2010 to 2019.
There is insufficient evidence to demonstrate that China has a dominant role over other countries/regions despite ranking third in CS. In future studies, it is recommended to include a KIDMAP visual to assess dominant roles in other areas of research, rather than to confine ourselves to CS as we did in this study.
科学比较优势是通过使用文章引文的专业化指数（SI）来衡量的。这些概况数据已经在文献中公布。但是，尚未有研究使用 SI 来确定哪些国家主导计算机科学（CS）领域（学科类别[SC]）。Rasch 模型中的 KIDMAP 已应用于显示学校中个别学生的表现。基于文章引文的 SI，我们使用 KIDMAP 来确定中国是否主导 CS 领域。
数据来自 Web of Science 发表的研究，其中包括 199 个国家和 254 个学科类别（SC，2010 年至 2019 年）。共提取了 96 个与生物医学相关的 SC。我们使用探索性因子分析检查了与 CS 相关的 7 个因素。基于 CS 下的 Rasch 模型中的 SI，在 Wright 地图和 KIDMAP 上显示了一维 CS。根据 Rasch 模型，基于 CS 的 SI，在散点图上呈现了中国在 CS 方面的主导地位分析。
我们的研究结果表明：（1）CS 领域分为 2 组（传统和先进领域）；（2）没有证据表明中国主导 CS；根据 SI 指标，中国在 2010 年至 2019 年期间在 CS 中排名第三，排名第三，在第一和第二因子中分别为-2.62 和 0.79 对数（-（-2.62 和 9.24 对数在因素 1 和 2）。
尽管中国在 CS 中排名第三，但没有足够的证据表明中国相对于其他国家/地区具有主导地位。在未来的研究中，建议包括 KIDMAP 视觉效果来评估其他研究领域的主导地位，而不仅仅是局限于我们在本研究中所做的 CS。
