In terms of its global significance, it surpasses the western model of ecological modernization, provides a new mode of ecological civilization for developing countries, and contributes Chinese wisdom to global ecological governance. Therefore, the philosophy of harmony between humanity and nature should be adhered to, strengthening the exploration of voice transmission and recognition of the modernization of harmony between humanity and nature and manifesting its global significance. Related Articles | Metrics Select  Application of Large Language Models in Automated Construction of Knowledge Graphs for University Subject Domains TANG Xiaosheng, CHENG Linya, ZHANG Chunhong, ZHU Xinning Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2024, 26 (1): 125-136.   DOI: 10.19722/j.cnki.1008-7729.2023.0107 Abstract （413）            Knowledge map    Save The rapid development of artificial intelligence has promoted the intellectualization in the field of education, and research on the construction of subject knowledge system by using knowledge graphs has emerged. The knowledge system constructed by knowledge graphs can model the correlation among knowledge points and form the course knowledge context, which is helpful for learners to memorize and understand knowledge in a deep level. However, the teaching resources of subject courses are diverse and scattered, and the existing automatic construction methods often use a single data resource with low resource utilization rate, which is difficult to provide guidance for the construction of professional knowledge systems. Moreover, low degree of automation and high cost need different modules to process the unstructured texts and generate the graphs, so reproducibility and portability are weak. Therefore, an optimization process of subject knowledge graph construction is proposed based on the large language model, which highly integrates the advantages of the large language model and the logical correlation of knowledge in various subjects. Specifically, taking the major of communication as an example, the powerful function of a large language model such as ChatGPT is used to design a knowledge system through subject knowledge analysis by using a variety of knowledge sources, so as to automatically extract knowledge entities and knowledge relations based on teaching resources to form a final subject knowledge system, which can also be introduced to other subject fields.  Related Articles | Metrics Select Ideological and Political Education in Universities from Perspective of Algorithmic Recommendation ZHOU Ye, LI Xinzhi Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2023, 25 (5): 1-6.   DOI: 10.19722/j.cnki.1008-7729.2023.0082 Abstract （381）            Knowledge map    Save With the development of artificial intelligence and big data, algorithmic recommendation has become a new variable affecting the shaping of university students’  values.

The application of virtual news anchors in the media field is emphasized. The public’s evaluation on the simulation dimension of virtual news anchors is measured through online experiments, the impact of simulation degree on users’ acceptance willingness is analyzed, and a structural equation model is used to examine the mediating role of the uncanny valley effect. It is revealed that the closer virtual digital humans align with human characteristics in terms of appearance, behavior and language habits, the more likely they are to elicit positive emotions in the audience. Consequently, this enhances audience acceptance levels, as well as their willingness to use and watch these digital humans. However, it is found that the mediating effect associated with the uncanny valley is absent. In other words, the uncanny valley effect didn’t exert a significant influence on audience’s willingness to use these virtual news anchors. The audience didn’t show observably negative emotions as simulation degree of virtual news anchors increases. Conversely, the audience more liked virtual news anchors who closely resembled humans, and expectations were formed for the application scenarios of virtual anchors of different genders.

Related Articles | Metrics Select Low-carbon City Pilot Policy and Enterprises’ Attention to Digital Transformation—A Quasi-experimental Study Based on Listed Manufacturing Enterprises in China WANG Yanyu, CHEN Yihan Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2024, 26 (1): 31-47.   DOI: 10.19722/j.cnki.1008-7729.2023.0075 Abstract （156）            Knowledge map    Save  The CPC Central Committee’s decision to reach peak carbon emissions before 2030 and achieve carbon neutrality before 2060 not only concerns a community with a shared future for mankind, but also, to some extent, adjusts the developing mode of China’s economy in the future. In the process of the great rejuvenation of the Chinese nation, low-carbon economy and digital economy are integrated, and low-carbon transformation and digital transformation complement each other. Therefore, the low-carbon city pilot policy from 2010 is taken as a “quasi-natural experiment”. Based on the micro-data of listed manufacturing enterprises from 2008 to 2020, the multi-time point DID (difference in differences) model is used to explore the influence of the policy on enterprises’ attention to digital transformation and its mechanism. The research shows that the low-carbon city pilot policy significantly improves enterprises’ attention to digital transformation; Enterprises located in pilot low-carbon cities pay 8.5% more attention to digital transformation than those not located in pilot low-carbon cities. This policy increases the attention of enterprises’ digital transformation through two mechanisms: risk at the enterprise level and enterprise output. In the heterogeneity analysis, the influence of this policy on the attention to enterprises’ digital transformation is significantly different among enterprises with different ownership and different ages. This paper provides an important empirical test for China’s listed manufacturing industry that should increase its attention to enterprises’ digital transformation in the low-carbon transformation, provides further research on the digital effect of policy effects, and lays a solid foundation for research on the cross-prospect of low-carbon and digitalization in the future.
