Clarifying the scope and activity within the large field of artificial intelligence (AI) can help research leaders, policymakers, funders and investors, and the public navigate AI and understand how it has evolved over time.
This effort can also provide clues to where AI is headed and how policies might be shaped to continue making advances in a responsible way. Elsevier’s new report Artificial Intelligence: How knowledge is created, transferred, and used provides insight into research output, collaboration and mobility for China, Europe and the United States. It's available to download free of charge.
Defining the field of AI
The report tackles the challenge of identifying artificial intelligence research by using AI techniques such as supervised and unsupervised learning. In doing so, it defines a multifaceted field across teaching, research, industry and media perspectives. It reveals seven AI research clusters, and provides insights on growth and regional trends in AI research. A case study offers an illustration of AI education in China, and the report delves into the essential role of ethics in AI.
To learn more about the technical background, please see our methodology document.
The report holds a special focus on delineating the field of AI bottom up by using AI technologies.
AI research clusters
The AI research field clusters around seven main research areas. Keyword clusters and co-occurrences in the AI field, 2017; the color of the keyword represents its originating perspective: Teaching: orange, Research: blue, Industry: green, Media: pink, Multiple perspectives: black. source: Scopus.
Seven interconnected fields of research appear in the analysis. You can investigate which terms appear and how they interact differently per region using our interactive co-occurrence charts: Global (all terms), China (core terms), Europe (core terms), USA (core terms). You might be interested to find that:
- Most AI topics have been around for more than two decades.
- The subfields of Machine Learning and Probabilistic Reasoning and Neural Networks have intensified in the last 5 years.
- A few topics reach a sufficient number of publications to become visible on the graphs, including Deep Learning and Swarm Intelligence in 2000, Transfer Learning in 2004, and Deep Neural Networks in 2005.
- This is the first step in scoping an emerging field. Further aspects, such as term hierarchies and full AI ontologies, are part of our ongoing research.
The report is a contribution to the wider dialogue around AI and cannot cover all aspects of the discussion. We are open and interested in further exchange with you. You may also be interested in the following seminal AI papers, hand-selected by our AI publisher:

Challenges, myths and realities
AI is a very hard field to circumscribe. Yet doing so is essential.
— Raymond Perrault, Senior Technical Advisor, AI Center, SRI International
AI is a very hard field to circumscribe because of the range of its problems of interest, diversity of its technical approaches, and dependence on other scientific areas for fundamental techniques and applications. Yet doing so is essential to understanding AI's technical progress, the resources it consumes and its impact on society. The methodology being developed in this study is a major step in defining its contours.
This era of symbiotic technology will untether us from screens and keyboards.
— Elsevier CTO Dan Olley in Forbes Magazine
In A CIO Hall of Famer’s Approach to Machine Learning, technology author Peter High interviewed Elsevier’s CTO and Executive VP of Product Development Dan Olley about tech trends and their applications at Elsevier and beyond. During the interview, Dan commented: "This era of symbiotic technology – enabled by combining AI, device miniaturization, 5G and an API-rich ecosystem – will untether us from screens and keyboards. As we think about training rather than programming these systems, new problems around bias and ethics will arise that we need to consider carefully."

Transferring and using AI are key aspects of the investigation of the field. In the report, we learned about AI as general purpose technology (see interview from Ingrid Ott, report page 80). We saw that its influence in application fields, such as self-driving cars, soccer robots or health applications, is around 30% (share of AI publications in the overall publication field).
For some of the fields, especially in Life Sciences and Health, we are applying AI ourselves to help researchers and clinicians advance science and health. With our partners, we are exploring the advantages, risks and realities of the AI technologies. To get a flavor of our activities please find some stories below:
