     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
    Abstract286)            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.

    Abstract170)            Save
    Based on the data of segmented patents and digital transformation of A-share listed companies from 2011 to 2021, the quantity and the quality of authorized patents are used to measure the level of groundbreaking innovation of enterprises, and the impact of digital transformation on groundbreaking innovation and its internal mechanism is empirically tested through the instrumental variable method and the time-varying DID (Difference-in-Differences) model. The study reveals that the digital transformation significantly promotes the level of groundbreaking innovation of enterprises, and the effect is more obvious in private enterprises, capital-intensive enterprises, enterprises in southern and coastal areas, high-tech industries and high-competitive industries. The mechanism analysis shows that the enhancement of groundbreaking innovation capability of enterprises is mainly caused by the optimization of the structure of labor force, the increase in R&D intensity and total factor productivity brought about by enterprises’ digital transformation. Further, it is found that smart city pilots promote the digital transformation and the improvement of groundbreaking innovation level of enterprises. Based on the quality of patents, it is found that there is a significant “U-shaped” relationship between digital transformation and groundbreaking innovation quality of enterprises. The above conclusions provide important empirical evidence and policy enlightenment for enterprises to accelerate the digital transformation and obtain groundbreaking innovation.

    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2023, 25 (6): 11-19.   DOI: 10.19722/j.cnki.1008-7729.2023.0125
    Abstract165)            Save
    With the rise of the metaverse concept, virtual digital humans are increasingly being applied in various industries. 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.

    Abstract127)            Save
    The New Basel III Market Risk Standard has made revolutionary revisions to the measurement logic of market risk capital. In order to understand its impact on commercial banks, its measurement logic and challenges are mainly analyzed. Based on assumed investment portfolios, calculation comparing the new and old standards is conducted. It is concluded that the implementation of the new market risk standard will significantly increase the level of market risk capital provision for commercial banks. It also makes higher requirements for market risk identification, measurement, systems, and limits management. It is recommended that relevant banks expedite business restructuring in line with the capital provisioning requirements of the new market risk standard. This may include, but is not limited to, appropriately increasing the proportion of interest rate bond investment in trading books, reducing the proportion of high-risk weighted bonds in credit bonds, and controlling the scale of unilateral traded options and unilateral precious metal trading businesses. These actions will promote the improvement of capital utilization efficiency. Meanwhile, it is suggested that commercial banks take the implementation of the New Basel III as an opportunity to comprehensively enhance their market risk measurement and management capabilities, laying a foundation for the development of market risk business.

    As an external form of online platform autonomy, online platform autonomous norms regulate social relations in cyberspace and carries the self-will of online platforms. On the surface, the autonomous norms of online platforms have the basic characteristics of private contracts, but in essence, the autonomous norms of online platforms are the manifestation of the “private power” of the platforms and have the nature of “quasi-law”.The necessity of judicial review of the autonomous norms of online platforms can be understood from four aspects: restraining the unlimited expansion of platform power, judicial authorities’ participation in platform governance, realizing the modernization of online platform governance, and remedying the rights and interests of online users. At present, the judicial authorities in China are not uniform in their standards of review of the autonomous norms for online platforms. The judicial review of the autonomous norms for online platforms should be improved in the following directions: to clarify the scope of judicial review; to break through the boundaries of private laws and to adopt a review standard combining legality and reasonableness; to distinguish different judicial review results; and to strengthen the coordination between judicial review and administrative management.
