Against the backdrop of rapid advances in artificial intelligence (AI) and the accelerating reshaping of the global technological competition landscape, interdisciplinary integration has increasingly become a critical driver of technological breakthroughs and knowledge innovation. Particularly amid intensifying Sino-American technological rivalry, comparing the differences in AI interdisciplinary knowledge integration paths across countries is of significant practical relevance for optimizing innovation strategies and enhancing competitive resilience. However, existing studies have predominantly focused on AI theory development, technological innovation, and overall trends, with relatively limited systematic exploration of AI’s interdisciplinary knowledge system and its evolutionary mechanisms. This gap partially constrains understanding of the intrinsic patterns of AI development and, consequently, limits the ability to seize strategic initiative.
This study draws on the Web of Science (WoS) database, selecting 89,448 valid publications up to December 31, 2024, and constructs an integrated research framework encompassing “topic identification - structural analysis - mechanism comparison”. First, employing the BERTopic modeling method, the study identifies representative interdisciplinary topics in AI and characterizes their features in terms of knowledge sources, integration depth, and structural types by introducing disciplinary diversity and cohesion indicators. Second, by analyzing changes in topic intensity and content evolution, it reveals the evolutionary paths and coupling patterns of interdisciplinary knowledge across different stages. Finally, using the United States and China as comparative cases, the study examines differences in topic distribution, structural patterns, and driving mechanisms, exploring how institutional logic, organizational forms, and resource allocation shape interdisciplinary integration.
The findings indicate that the AI field has formed a complex interdisciplinary knowledge system composed of 23 heterogeneous topics, with significant variation across topics in disciplinary sources, integration depth, and structural complexity, displaying a combination of parallel paradigms, heterogeneous integration, and structural coupling. The evolution of interdisciplinary knowledge typically follows a cyclical process, progressing from the introduction of heterogeneous elements to the integration of methodological paradigms and the differentiation of new subfields, with coupling realized through multi-layered nested coordination between core and interface disciplines. International comparison shows that the U.S. emphasizes paradigm-driven, system-level diffusion, relying on open collaboration and multi-actor participation to promote parallel exploration across multiple directions, whereas China exhibits an engineering- and application-driven pattern, emphasizing concentrated resource mobilization and rapid integration, resulting in goal-focused and outcome-oriented pathways. These mechanistic differences not only influence the pace and direction of knowledge evolution but also shape each country’s relative advantages in frontier leadership and applied breakthroughs.
The study proposes high-level strategic directions for enhancing China’s interdisciplinary integration capacity and systemic innovation resilience in AI, including the development of heterogeneous coupling platforms, optimization of project and collaboration mechanisms, and the cultivation of interface discipline ecosystems. The research systematically extends the characterization of interdisciplinary knowledge structures, the identification of evolutionary paths, and comparative analysis of U.S. and Chinese mechanisms, offering a generalizable analytical framework and methodological approach. It deepens understanding of the patterns and mechanisms of interdisciplinary integration in AI and provides a novel theoretical perspective for studying the complexity of technological convergence. By elucidating cross-national differences in interdisciplinary innovation paths and driving logics, the study provides scholarly support and practical guidance for formulating forward-looking AI development strategies and strenthening competitiveness global technological competition.

面对人工智能(AI)技术快速演进的新形势,跨学科融合日益成为推动技术突破与知识创新的重要路径。然而已有研究鲜有探讨AI的跨学科知识及其演进体系,制约了对AI发展内在规律的理解,进而影响掌握发展主动权的能力。该研究聚焦AI领域的跨学科知识融合与结构演化问题,引入BERTopic模型,运用学科多样性与凝聚力指数和主题强度与内容演化分析方法,构建“主题识别-结构解析-机制比较”研究框架,识别全球AI领域的典型跨学科主题,系统分析其知识结构特征与演进模式,并聚焦中美两国的演化路径差异与驱动机制对比。研究发现,AI领域形成23个结构类型各异、融合程度不一的跨学科主题,呈现多范式共生、异质知识集成与结构耦合演进的特征,表明AI本身已成为复杂技术-社会系统中典型的跨学科集成平台;中美分别形成“范式驱动-系统扩散型”(美国)与“任务导向-技术整合型”(中国)两类典型路径,在制度逻辑、组织机制与资源配置方面展现出深层差异,美国侧重自由探索与多元协同,中国则强调战略导向与集中攻关。研究提出构建异质耦合平台、优化立项机制、完善接口学科生态等政策建议,以增强中国AI领域的跨学科整合能力与系统创新韧性。研究有助于深化对AI跨学科知识生产和演进规律的理解,并为评估中美科技竞争态势提供学理支撑与启示。

349(6245): 255-260., articleTitle=Machine learning: Trends, perspectives, and prospects, refAbstract=Machine learning addresses the question of how to build computers that improve automatically through experience. It is one of today's most rapidly growing technical fields, lying at the intersection of computer science and statistics, and at the core of artificial intelligence and data science. Recent progress in machine learning has been driven both by the development of new learning algorithms and theory and by the ongoing explosion in the availability of online data and low-cost computation. The adoption of data-intensive machine-learning methods can be found throughout science, technology and commerce, leading to more evidence-based decision-making across many walks of life, including health care, manufacturing, education, financial modeling, policing, and marketing.

40(4): 602-610., articleTitle=Dual-transition of sectoral innovation ecosystem empowered by artificial intelligence, refAbstract=Nowadays, artificial intelligence (AI), as a main force leading the new round of disruptive industrial change, begin to spread and accelerate enabling in various fields. Meanwhile, the artificial intelligence enables the “double transition” of technology innovation and application innovation, which puts forward emerging challenges to sectoral innovation ecosystem (SIES) from multi-dimensions, such as the production factors, the function boundary, the interaction relationship, etc. The transitions of SIES empowered by AI leads to following thinking in this paper: what original changes will AI enable the main composition and biological community of SIES? What breakthrough changes will AI enabling make in the main ecological position and interactive relationship in SIES? What disruptive changes will take place in industrial pattern due to the transitions of SIES empowered by AI? Learning lessons from theories of nature ecosystem and SIES, this paper constructs the theoretical framework of dual-transition (including core driving layer -industrial pattern change layer) empowered by AI, and the operation logic and industrial revolution within SIES are analyzed by the case study of autonomous driving. It mainly includes two steps in this part. First, based on the theoretical framework of SIES transition, this paper reveals the dynamic process of “core drive leading to industrial change”, and explains the new interactions among innovators in the SIES. To explore the core driving layer, the article also draws the cross-sectional view of the evolution from “traditional quadruplex helix” to “emerging quadruplex helix”, which also explains the generation of multi-homing actor and secondary communities in the SIES. Second, taking autonomous driving as an example, this paper gives the keywords’ co-occurrence network of autonomous driving SIES, and makes practical analysis on four aspects of SIES transition empowered by AI. The research findings are as follows: first, the emergence of multi-homing actor and secondary communities give rise to the new ecological interaction of SIES, and it becomes the core driver pushing SIES from traditional quadruplex helix to emerging quadruplex helix. Second, the interaction of core driving and industrial change are increasingly enhanced, and multi-homing actor and secondary communities continuously trigger industrial practice changes. These make characteristics of industrial patterns tend to reconstruct of value distribution, upgrade of intelligent manufacturing, adaptation of business model, and revolution of organizational decision-making. All in all, an emerging SIES integrating “core driving layer - industrial pattern change layer” empowered by AI is becoming clearer and clearer. This paper contributes to existing research in the following two aspects: first, it puts forward and demonstrates new concepts of multi-homing actor and secondary communities. And it explains the emerging quadruplex helix innovation by exploring secondary communities including technological innovation, product manufacturing, market application and policy regulation. By interpreting the existence of multi-homing actor and secondary communities, this paper break through the theoretical dilemma about the fuzzy function boundary in SIES. Second, by describing the industrial patterns and emerging characteristics empowered by AI, this paper verifies the practical transition (such as reconstruct of value distribution, upgrade of intelligent manufacturing, adaptation of business model, and revolution of organizational decision-making) of autonomous driving SIES, which strongly proves that AI enabling is triggering ubiquitous changes in industrial patterns.), Reference(id=1317436198524665960, tenantId=1146029695717560320, journalId=1308397381743640680, articleId=1317436186684145696, doi=10.1162/qss_a_00329, pmid=null, pmcid=null, year=2024, volume=5, issue=4, pageStart=922, pageEnd=935, url=https://direct.mit.edu/qss/article/5/4/922/124451/Interdisciplinary-research-in-artificial, language=null, rfNumber=[9], rfOrder=12, authorNames=Abbonato D, Bianchini S, Gargiulo F, journalName=Quantitative Science Studies, refType=null, unstructuredReference=

Under the guidance of Professor Qian Xuesen’s theory of technological science, exploring the internal mechanisms of knowledge evolution in artificial intelligence holds profound theoretical and practical significance for promoting sustainable technological advancement. This study draws on literature from the Web of Science (WOS) database and employs methods such as knowledge mapping, natural language processing, clustering analysis, and citation analysis to outline the knowledge structure of the field, clarify the trajectory of sustainable development, and trace the technological genealogy of VR/AR technologies.This study divides the knowledge structure within the field of technological science into “basic theoretical knowledge—applied basic knowledge—applied knowledge”, enriching Qian’s theory of technological science from within and providing strong intellectual support and technological pathways for sustainable technological development in practice. Artificial intelligence encompasses 10 distinct knowledge domains, among which machine learning and deep learning constitute the basic theoretical knowledge, data intelligence, computer vision, and swarm intelligence are the applied basic knowledge, and image processing and human-computer intelligence are the applied knowledge. The development of VR/AR technology has formed two main sustainable development paths: “machine learning—data intelligence—intelligent systems—human computer intelligence”, and “deep learning—computer vision—image processing”.), Reference(id=1317436199447412850, tenantId=1146029695717560320, journalId=1308397381743640680, articleId=1317436186684145696, doi=null, pmid=null, pmcid=null, year=2021, volume=40, issue=8, pageStart=831, pageEnd=845, url=null, language=null, rfNumber=[15], rfOrder=22, authorNames=王卫军, 姚畅, 乔子越, journalName=情报学报, refType=null, unstructuredReference=王卫军, 姚畅, 乔子越,

Frontiers in Sociology,

7: 886498., articleTitle=A topic modeling comparison between LDA, NMF, Top2Vec, and BERTopic to demystify twitter posts, refAbstract=The richness of social media data has opened a new avenue for social science research to gain insights into human behaviors and experiences. In particular, emerging data-driven approaches relying on topic models provide entirely new perspectives on interpreting social phenomena. However, the short, text-heavy, and unstructured nature of social media content often leads to methodological challenges in both data collection and analysis. In order to bridge the developing field of computational science and empirical social research, this study aims to evaluate the performance of four topic modeling techniques; namely latent Dirichlet allocation (LDA), non-negative matrix factorization (NMF), Top2Vec, and BERTopic. In view of the interplay between human relations and digital media, this research takes Twitter posts as the reference point and assesses the performance of different algorithms concerning their strengths and weaknesses in a social science context. Based on certain details during the analytical procedures and on quality issues, this research sheds light on the efficacy of using BERTopic and NMF to analyze Twitter data.), Reference(id=1317436200567292032, tenantId=1146029695717560320, journalId=1308397381743640680, articleId=1317436186684145696, doi=10.1007/s11192-023-04776-5, pmid=null, pmcid=null, year=2024, volume=129, issue=11, pageStart=7359, pageEnd=7384, url=null, language=null, rfNumber=[23], rfOrder=36, authorNames=Wang Z, Chen J, Chen J, journalName=Scientometrics, refType=null, unstructuredReference=
