Current status and trends of artificial intelligence research on the four traditional Chinese medicine diagnostic methods: a scientometric study

Abstract

Background: With the development of technology and the renewal of traditional Chinese medicine (TCM) diagnostic equipment, artificial intelligence (AI) has been widely applied in TCM. Numerous articles employing this technology have been published. This study aimed to outline the knowledge and themes trends of the four TCM diagnostic methods to help researchers quickly master the hotspots and trends in this field. Four TCM diagnostic methods is a TCM diagnostic method through inspection, listening, smelling, inquiring and palpation, the purpose of which is to collect the patient's medical history, symptoms and signs. Then, it provides an analytical basis for later disease diagnosis and treatment plans. Methods: Publications related to AI-based research on the four TCM diagnostic methods were selected from the Web of Science Core Collection, without any restriction on the year of publication. VOSviewer and Citespace were primarily used to create graphical bibliometric maps in this field. Results: China was the most productive country in this field, and Evidence-Based Complementary and Alternative Medicine published the largest number of related papers, and the Shanghai University of Traditional Chinese Medicine is the dominant research organization. The Chengdu University of Traditional Chinese Medicine had the highest average number of citations. Jinhong Guo was the most influential author and Artificial Intelligence in Medicine was the most authoritative journal. Six clusters separated by keywords association showed the range of AI-based research on the four TCM diagnostic methods. The hotspots of AI-based research on the four TCM diagnostic methods included the classification and diagnosis of tongue images in patients with diabetes and machine learning for TCM symptom differentiation.Conclusions: This study demonstrated that AI-based research on the four TCM diagnostic methods is currently in the initial stage of rapid development and has bright prospects. Cross-country and regional cooperation should be strengthened in the future. It is foreseeable that more related research outputs will rely on the interdisciplinarity of TCM and the development of neural networks models.

Translational analysis of data science and causal learning in real-world clinical evaluation of traditional Chinese medicine

“…First, with the collection methods of big data in TCM, valuable data on four examinations (inspection, listening and smelling, inquiry, pulse taking, and palpation) and clinical outcomes can be quickly obtained, providing comprehensive and reliable information for RWCE-TCM. [28,29] Second, TCM big data preprocessing methods enable rapid data encoding, annotation, structuring, standardization, and outlier detection, making the data more accessible to analyze and understand. [30] Third, TCM big data analysis methods can quickly conduct data description, visualization, and modeling, as well as mine the explicit knowledge and implicit knowledge of TCM, making TCM studies understandable, acceptable, quantifiable, and empirical.…”

Analysis of Diagnostic Methods, Etiology and Pathogenesis of Traditional Chinese Medicine

“…Traditional Chinese medicine pathogenesis is one of the important disciplines in traditional Chinese medicine, which studies the occurrence, development, and pathological changes of diseases, mainly including etiology, pathogenesis, syndrome differentiation, and pathology (Tian et al, 2023). Traditional Chinese medicine pathogenesis is an important component of traditional Chinese medicine, which studies the occurrence, development, and pathological changes of diseases, providing an important theoretical basis for the differentiation, treatment, and treatment of traditional Chinese medicine.…”

Intelligent quality control of traditional chinese medical tongue diagnosis images based on deep learning

“…Tongue and facial examination are essential parts of “Inspection” [ 2 ]. In TCM theory, doctors must observe the shape, color, and texture of the patient’s tongue.…”
