A Comparative Analysis of Hotspots in Semiotics Theory Research in China and Abroad: A Knowledge Mapping Analysis Based on CiteSpace

Based on literature data with "semiotics theory" as the research topic from the CNKI and WOS databases, this study employs CiteSpace software to conduct a comparative analysis of the relevant research on semiotics theory in China and abroad from 2000 to 2022. The results show that: Domestic and international research on semiotics theory exhibit a multi-centered development trend, gradually forming distinctive and complementary schools of semiotics theory. China's and abroad research focuses differently, with foreign research focusing more on applying semiotics theory in social sciences, educational research, language fields, and biological sciences. In contrast, domestic research tends to focus on introducing and studying foreign semiotics theories, with linguistics being an important research area. Both domestic and international research on semiotics theory have expanded the scope of theoretical research, forming widely applicable categories of semiotics. Hotspots in foreign research include "student";"model"; "future"; "evolution"; "information"; "framework"; "discourse"; and "construction", while hotspots in domestic research include "semiotics", "Peirce", "pragmatism", "Lotman", and "symbols". The development process of domestic and international research on semiotics theory has some differences, with each stage exhibiting different research characteristics. However, both have developed from theoretical to applied research, phenomenon to essence law research, and single-mode to multi-mode research. Domestic researchers should strengthen communication and cooperation with international counterparts, build a research community for semiotics theory, deepen research connotations, and provide more case studies as paradigms; timely summarize the current status and development patterns of domestic research on semiotics theory, and gradually form a Chinese school of semiotics with international influence.

Visual Analysis of Research on Chinese Phonetics Teaching Based on China National Knowledge Infrastructure

In this paper, CiteSpace analysis was used to summarize the Chinese phonetics teaching in the past 42 years for visual analysis. Firstly, we manually searched the China National Knowledge Infrastructure (CNKI) database from 1982-2024, and got 961 valid documents after de-emphasis, which were imported into CiteSpace software for the visual knowledge mapping analysis. In terms of keyword clustering, we obtained 10 keyword clusters in 4 major categories, such as phonological ontology knowledge, bias analysis, pedagogical suggestions, and country-specific analysis. In terms of keyword emergence, we found that the academic community has focused on the study of Chinese phonological ontology from 1994 to 2013, and that the term "pedagogical strategies" first appeared in 1999, followed by a slow transition in 2011, and then a slow transition in 2011, and a slow transition in 2011. Research on "teaching and learning" has always been in the hot spot. The number of articles published in 2012 and 2014 had two high points, 39 and 41, respectively. Finally, the author suggests that the research on Chinese phonetics will continue to grow, and with the rapid development of information technology, Chinese phonetics will integrate more new media and educational technology tools to improve teaching efficiency and quality.

A bibliometric review of perceptions of the built environment supported by multi-source data

ABSTRACT Information and digital technologies have revolutionized research methodologies for measuring people’s perceptions of built environments. Vast amounts of urban data can now be collected, providing more accurate and intuitive presentation and analysis tools. This enhances the research on the built environment from a human-centered perspective. In this paper, with the help of the CiteSpace knowledge map analysis tool, manual deep intervention was combined with clustering and stratified sampling of literature information to identify hot topics and research trends. The results demonstrate that there are two new perspectives. The first is the up-bottom urban/group perspective, specifically a holistic study of group perceptions by large-scale data, represented by big data, with technologies such as artificial intelligence. The second is the bottom-up humanistic/individual perspective, which accurately examines individual perceptions through physiological data based on ergonomics techniques, psychological, and other small-scale data. Furthermore, these two perspectives are interconnected, indicating a cross-trend in both directions. By bridging the gap between subjective perception and the real-world environment, integrating multi-source data offers a more precise and efficient foundation for thoroughly evaluating the built environment, which would help us better understand the built environment and satisfy the users’ demands in the research and practice of urban design.
