     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

    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.

    With the rapid development of Internet communication technology, humans have undoubtedly entered the era of big data. This era has also put forward new requirements for the construction of digital government, that is, from government information disclosure to government data openness. In order to meet the new requirements, China has implemented a series of policies and measures for the open utilization of government data through the overall integration of government information work. Whether in the process of legal system construction, organizational structure establishment, or platform construction, significant achievements have been made in the open utilization of government data. However, there are still challenges such as low legislative level and neglect of application due to much management, difficulty in grasping data ownership and opening scope, difficulty in implementing data opening procedures, insufficient motivation and ability for data opening, inadequate supervision and management of data open utilization, and less influence of data applications. In order to further institutionalize and standardize the management of government data open utilization, it is necessary to establish an efficient and collaborative organizational operation system, establish a legal norm system for government data open utilization, establish a specialized talent guarantee system, establish a sound supervision and evaluation work system, and create and optimize the environment for government data development and utilization, to promote the legal development of government data open utilization in depth.

    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2023, 25 (6): 50-58.   DOI: 10.19722/j.cnki.1008-7729.2023.0110
    Abstract89)            Save
    “Knowing” is the key constituent element of the crime of assisting in information network criminal activities. The understanding of “knowing that others use information network to commit crimes” should start from the connotation of “knowing”, and delimit the subset of “knowing” according to whether it meets the condition of “at least with uncertain intention”. Based on the essence of the crime of assisting in information network criminal activities to explain the object of “knowing”, the perpetrator only needs to have a general understanding of others relying on information network to commit crimes. Then settle on the identification of “knowing”, and classify the situation that meets the requirements of “knowing” into types of knowing with clear meaning contact, knowing without clear meaning contact, and comprehensive presumption of “should know”. The former two correspond to the knowledge of collusion and non-collusion in practice and the latter includes the circumstances which can prove the existence of “malicious behaviors” such as the actor being presumed to know according to the specific content of the assistance provided and according to the repeated assistance provided.

    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2023, 25 (5): 63-74.   DOI: 10.19722/j.cnki.1008-7729.2023.0063
    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.

    Web crawler is an emerging Internet technology used to automatically search and crawl the specified network information according to the order, but there is a risk of being abused. Web crawler is a tool of crawling network copyright data information, and copyright infringement by web crawling behaviors happens frequently. At present, regulations for copyright infringement by web crawling behaviors are always found in civil laws and criminal laws, while administrative regulations are ignored. Current administrative regulations for copyright infringement by web crawling behaviors have problems that they rely too much on judicial means, and lack norms and online supervision made by administrative organizations. All these hinder the application and development of administrative regulations for copyright infringement by web crawling behaviors. In this regard, administrative means should be used to restrain copyright infringement by web crawling behaviors and protect the legal interests of copyright owners through building a full-coverage warning system, improving the copyright management, and setting up self-regulatory obligations for web crawler users, etc.

    After National Press and Publication Administration began to supervise online games, although the department implemented the first administrative punishment for violating the anti-addiction management regulation in 2021, the gap of online games supervision has not been completely filled. From the perspective of the impact of games on survival, entertainment and capital, cyber-human and their cyber behaviors have been completely digitized, and cyber-human’s body and mind have completely left the digital game, only becoming a symbol of capital value added. Although the “Internet Information Service Algorithm Recommendations Management Regulations” has defined “inducing users to indulge in games and over-consume” to a certain extent, the effect of regulation is not obvious. The regulations also face the argument of cyber-human’s free will to choose indulgence, and the difficulty in balancing the huge social value with personal value of online games. The overall regulation has become a trend, so it is advisable to establish a standard for Internet addiction disorder based on the laws, in order to lay a foundation for declaring tort liability for online addiction, and to actively establish a public interest litigation mechanism, improve algorithm administrative ability and detail the supervision models for algorithm.

     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.
