    [Purpose/Significance] Researchers are the main force of discipline construction in universities. Analyzing and measuring the characteristics of talent team structure and their development is conducive to summarizing the laws of discipline talent team in world-class universities, and analyzing its influence on the long-term development of disciplines, which can provide guidance for universities' discipline construction in China. [Method/Process] A structural characteristics analysis and measurement system of talent team was constructed based on papers published in different fields of research, and by using the methods of scientometrics, and social network analysis. There are 12 indicators in total, which include 4 aspects: internal structure, stability, correlation of research content and internal cooperation of talent team. Then, the correlation models between the characteristics of talent team structure and the productivity, influence of disciplines are constructed to analyze the influences of talent team structures on the development of disciplines in universities. The data of 10 world-class universities in computer science from 2001 to 2020 are used for empirical analysis. [Results/conclusions] The study shows that the correlation between the different characteristics of talent team structure and discipline productivity is not significant, but it has different influences on the overall influence of disciplines. Among them, the relevance of research content and the close degree of cooperation among the main members have obvious promotion effect on discipline influence. The stability of the main team members also has a certain degree of influence on the discipline performance. However, the internal structure and other characteristics, such as the proportion of top talent, are relatively weak in relation to discipline influence. Based on this, it is proposed that in the process of discipline development, universities should strengthen the stability of the main team members, the relevance of research contents and the closeness of cooperation, and form stable and closely linked core research teams, so as to continuously improve the level of discipline development.

    Abstract328)      PDF(pc) (8494KB)(6662)       Save
    [Purpose/Significance] In the digital era of the Internet of Things, data-intensive academic research paradigms have accelerated, promoting the reconstruction of research libraries' new knowledge service ecology based on massive resources and data. With the development of smart libraries, "web-scale discovery service" has become the core functional module for the implementation of intelligent services in the next-generation library service platform. Which kind of next-generation library service platform is more suitable for building web-scale discovery services? How to build web-scale discovery services? These are issues that the library industry pays more attention to in building smart libraries. [Method/Process] This article mainly adopts a research method that combines literature review with case studies. It reviews the current research status of "web-scale discovery service" both domestically and internationally, and uses the Shanghai Library as a case study for empirical research. It takes the exploration of intelligent data service mode of Shanghai Library's third-generation service platform as the research object, reviews the technical path, resource strategy, data management, and service methods of the web-scale discovery services based on the FOLIO platform micro-services architecture, and explores new ideas and new technologies for improving the value of knowledge services through "user-centered" web-scale discovery services in the digital transformation of libraries. [Results/Conclusions] Micro-services architecture is a service-oriented architecture with high flexibility and scalability. Based on the FOLIO platform's micro-service architecture and using the open-source discovery tool Vufind as a resource discovery portal, libraries can build their next-generation service platform suited for building web-scale discovery services in smart libraries. This platform allows customization and expansion of additional intelligent service modules as needed, to meet different levels of service demands. Therefore, the author suggests that libraries should choose the open-source FOLIO platform, which utilizes micro-service architecture to serve as the next-generation service platform for smart libraries. Additionally, librarians are encouraged to customize and develop personalized web-scale discovery services, considering their specific needs. Due to the fact that the research object of this article is a large-scale research library in China, the practical experience and research methods presented here have certain limitations. We hope that the research conclusions of this article can provide references for librarians when selecting and implementing relevant systems and services for building web-scale discovery services.

    [Purpose/Significance] Gradient theory reveals the causes and evolutionary trends of the uneven development of networks. As one of the most promising urban agglomerations in China, the middle reaches of Yangtze River urban agglomeration is the most representative national central urban agglomeration, which plays a key role in supporting the construction of central rising strategy. Therefore, it has become an important proposition of increasing concern for researchers and policy makers in the management field to study the technology innovation cooperation network in the middle reaches of Yangtze River urban agglomeration, in order to strengthen the innovation cooperation among cities and accelerate the construction of innovative cities and coordinated regional development. [Method/Process] Based on the perspective of gradient theory, this paper explores the structure and evolution of technology innovation cooperation networks in the middle reaches of Yangtze River urban agglomeration at the level of internal dynamics with the help of two important conditions that need to be met by high-gradient cities, evolving city structure stratification from core-edge structure and city role positioning from structural holes and intermediaries. [Results/Conclusions] It is found that the technology gradient in the middle reaches of Yangtze River urban agglomeration is mainly manifested by the polarization effect, and the technology gap between cities is widened. Due to the small number of high-gradient cities, they have not been able to form a driving scale benefit, and the overall regional technology innovation performance is not strong. This paper can provide useful references for the synergistic development of the middle reaches of Yangtze River urban agglomeration from the aspect of technology innovation cooperation.

    [Purpose/Significance] In recent years, large language models (LLMs) have achieved revolutionary breakthroughs in semantic understanding and generation capabilities through massive text pre-training. This has injected brand-new impetus into the field of knowledge engineering. As a structured knowledge carrier, the knowledge graph has unique advantages in integrating heterogeneous data from multiple sources and constructing an industrial knowledge system. In the context of a paradigm shift in the field of knowledge engineering driven by the emergence of open-source LLMs such as DeepSeek, this study proposes a cost-effective method for constructing domain knowledge graphs based on DeepSeek. We aim to address the limitations of traditional domain knowledge graphs, such as high dependence on expert rules, the high cost of manual annotation, and inefficient processing of multi-source data. [Method/Process] We proposed the semantic understanding-enhanced, cue-engineered domain knowledge extraction technology system, constructed on the methodological framework of manually constructing ontology modelling. In order to process the acquired data, the ETL\MinerU and other tools were used, and the DeepSeek-R1application programming interface was then invoked for intelligent extraction. The ontology model was designed based on domain cognitive features and the multi-source heterogeneous data fusion method was used to achieve the unified characterization of the data structure. Furthermore, the DeepSeek and knowledge extraction were combined. Our system provides a cost-effective reusable technical paradigm for constructing domain knowledge graphs, as well as efficient knowledge extraction, leveraging the advanced powerful textual reasoning ability of the DeepSeek model. [Results/Conclusions] In this study, we take the construction of a domain knowledge map of the entire pig industrial chain as an empirical object. We define the structure of the industrial chain, identify 21 types of core entities and describe their attribute relationships. We achieve the knowledge modelling of the pig industry with a focus on smart farming. The methodology developed in this research was also employed to process and extract knowledge from online and offline resource data. Preliminary experiments demonstrate that DeepSeek-R1 exhibits an F1 value of 0.92 when recognizing the attributes of 161 diseases and 11 types of entities in pig disease control scenarios under zero-sample learning conditions. These experiments also ascertain the reusability of the methodology for other links in the chain. Concurrently, the constructed knowledge map of the entire industrial chain of pigs will be utilized for the design and validation of intelligent application scenarios, with the objective of promoting the intelligent information processing in the pig industry. This study proposes a synergistic paradigm for constructing domain knowledge graphs using DeepSeek, a method that combines deep learning with manual calibration for efficient knowledge extraction and ensure accuracy. This approach ensures the efficiency of knowledge extraction and verifies the knowledge extraction potential of LLMs in vertical domains. The study's findings contribute to the extant literature and offer a practical reference for the promotion of DeepSeek-enabled cost-effective construction of knowledge graphs.

    [Purpose/Significance] Scientific literature contains rich domain knowledge and scientific data, which can provide high-quality data support for AI-driven scientific research (AI4S). This paper systematically reviews the methods, tools, and applications of arge language models (LLMs) in scientific literature data mining, and discusses their research directions and development trends. It addresses critical shortcomings in interdisciplinary knowledge extraction and provides practical insights to enhance AI4S workflows, thereby aligning AI capabilities with domain-specific scientific needs. [Method/Process] This study employs a systematic literature review and case analysis to formulate a tripartite framework: 1) Methodological dimension: Textual knowledge mining uses dynamic prompts, few-shot learning, and domain-adaptive pre-training (such as MagBERT and MatSciBERT) to improve entity recognition. Scientific data extraction uses chain-of-thought prompting and knowledge graphs (such as ChatExtract and SynAsk) to parse experimental datasets. Chart decoding uses neural networks to extract numerical values and semantic patterns from visual elements. 2) Tool dimension: This explores the core functionalities of notable AI tools, including data mining platforms (such as LitU, SciAIEngine) and knowledge generation systems (such as Agent Laboratory, VirSci), with a focus on multimodal processing and automation. 3) Application dimension: LLMs produce high-quality datasets to tackle the issue of data scarcity. They facilitate tasks such as predicting material properties and diagnosing medical conditions. The scientific credibility of these datasets is ensured through a process of "LLMs + expert validation". [Results/Conclusions] The findings indicate that LLMs significantly improve the automation of scientific literature mining. Methodologically, this research introduces dynamic prompt learning frameworks and domain adaptation fine-tuning technologies to address the shortcomings of traditional rule-driven approaches. In terms of tools, cross-modal parsing tools and interactive analysis platforms have been developed to facilitate end-to-end data mining and knowledge generation. In terms of applications, the study has accelerated the transition of scientific literature from single-modal to multimodal formats, thereby supporting the creation of high-quality scientific datasets, vertical domain-specific models, and knowledge service platforms. However, significant challenges remain, including insufficient depth of domain knowledge embedding, the low efficiency of multimodal data collaboration, and a lack of model interpretability. Future research should focus on developing interpretable LLMs with knowledge graph integration, improving cross-modal alignment techniques, and integrating "human-in-the-loop" systems to enhance reliability. It is also imperative to establish standardized data governance and intellectual property frameworks to promote the ethical utilization of scientific literature data. Such advances will facilitate a shift from efficiency optimization to knowledge generation in AI4S.

    [Purpose/Significance] At present, governments at different levels in China are faced with some problems and challenges in opening up government data such as lagging policy legislation, data unable to meet public demand, insufficient platform service function and integration, imperfect data openness innovation mechanism, and a lack of unified management institutions. The purpose of this paper aims at construction of a stage maturity model to build an evaluation indicator system to measure government data openness maturity, It is important for the local government to understand which level of development their open data is at and which areas need to be improved, in order to comprehensively understand and grasp the actual level of local government data openness in China, which is important for strengthening the construction of sunshine government and e-government, optimizing the process of government data openness, and promoting the innovative development of government data openness. [Method/Process] Based on the idea of the software capability maturity model Capability Maturity Model (CMM), the Chinese government data openness maturity model was constructed, and then a data openness evaluation indicator system was also established on the basis of the maturity model. The government data openness maturity model includes strategic level, data level, technical level, organizational level and application level, and the levels are divided into five categories: initial level, document level, development level, open level and optimization level. The evaluation indicator system consists of 5 primary indicators, 11 secondary indicators and 35 tertiary indicators. The combination weights of the indicators were calculated by using the AHP-entropy weight method. Then, we designed the scoring rules, set the scoring criteria, and scored the four municipalities directly under the central government of China according to the actual situation. [Results/Conclusions] According to the ratings of the four municipalities, Shanghai has a good overall performance, followed by Beijing, Tianjin, and Chongqing. The municipalities directly under the central government are better in terms of related policies launched, but they are lacking in terms of platform function construction, the degree of perfection of local policies and regulations, and the interaction ability with users, which need to be further strengthened. The open government data evaluation indicator system proposed in this paper needs continuous improvement in terms of indicator selection and scoring criteria. In some aspects, the effect of using one indicator alone may not be satisfactory, and the follow-up study involving more elements will summarize more experiences and collect more experts' opinions in the field of government data openness to further improve the government data openness maturity evaluation indicator system.

    Twenty Years of Left-Behind Children Education in Rural China: Based on Structural Topic Model
    WANG Xing, LI Yeye, ZHOU Tianyu, LIU Feng
    Journal of library and information science in agriculture    2023, 35 (9): 43-56.   DOI: 10.13998/j.cnki.issn1002-1248.23-0691
    Abstract583)      PDF(pc) (3126KB)(3704)       Save
    [Purpose/Significance] The introduction of national poverty alleviation policies and rural revitalization strategies has thrust the issue of education for left-behind children into the spotlight of scholarly attention. Education, far beyond serving as a mere instrument for personal growth and human capital accumulation for left-behind children, emerges as a pivotal measure in consolidating rural poverty alleviation endeavors and breaking the transmission of intergenerational poverty in China. It stands as a vital force propelling the future of rural revitalization. Yet, the existing literature on the education of left-behind children remains sporadic and dispersed. A more profound organizational effort, integrating, synthesizing, and evaluating this scattered literature, is imperative to establish a foundational framework for future research, fostering more cohesive and focused research endeavors. Presently, literature review studies primarily fall into three categories: qualitative review methods, meta-analysis, and bibliometric analysis methods employing tools like Citespace. This study sets out to achieve a systematic and comprehensive understanding of education-related issues for rural left-behind children through text mining methods grounded in topic models. [Method/Process] The advent of artificial intelligence and machine learning technologies has empowered the processing and analysis of vast amounts of textual data. Previous research, employing latent dirichlet allocation (LDA) topic models, successfully mined texts related to teacher team construction reform policies, internationalization in higher education literature, news reports, and online comments. In this study, a corpus was meticulously constructed using abstract texts extracted from 2037 journal articles published between 2002 and 2023. The structural topic model (STM) was chosen for topic modeling, overcoming the limitations associated with LDA, with a specific emphasis on exploring the diversity and dynamism of topics within the existing literature. [Results/Conclusions] The culmination of this research effort identified eight distinct research themes: psychological well-being, factors leading to left-behind children, macro-level coping strategies, types of guardianship, review studies, family education, media literacy, and micro-level coping strategies. By synergizing document metadata information, the study systematically unraveled the evolving trends of these topics over time, providing crucial insights into potential shifts in the focus of left-behind children's education research. It is essential to note that this study, while collecting abstracts instead of full texts, may not capture the entirety of information contained in complete research articles. Future research endeavors should explore left-behind children's education more comprehensively, leveraging full-text mining techniques for a more nuanced understanding of this critical subject.

    Structure-Utility of Descriptive Information of Agricultural Scientific Data from the Perspective of Users
    FAN Zhixuan, WANG Jian, SA Xu, ZHANG Guilan
    Journal of library and information science in agriculture    2022, 34 (10): 57-69.   DOI: 10.13998/j.cnki.issn1002-1248.22-0330
    Abstract410)      PDF(pc) (2671KB)(3615)       Save
    [Purpose/Significance] This paper aims to study the structure-utility relationship of descriptive information of scientific data to provide a new perspective for the theoretical study of scientific data description and a reference for the best description of agricultural scientific data in the digital environment. [Method/Process] Based on information processing theory, the lens model, the probabilistic mental model theory and the adaptive decision-making behavior framework, the relationship model between descriptive information structure and informing utility was constructed. A situational experiment was designed according to the model. In this study, 47 postgraduates from 14 institutes were invited for quasi-experimental observation by using qualitative and quantitative methods such as eye-tracking, semi-structured interview and questionnaire. First, this study used a semi-structured interview to obtain a user's cognitive interpretation of fixation points and collected the descriptive items of agricultural scientific data and their use frequency by encoding the interview text. Second, this study combined descriptive item usage path coding and user judgment confidence to obtain the combination of descriptive items with high utility. Finally, the study used multiple regression analysis to identify the descriptive items with high utility and their predictive ability, and analyzed the impact of data literacy and data utilization type on the utility of descriptive items. [Results/Conclusions] The study identified 42 descriptive items of 11 categories of agricultural scientific data and their usage characteristics. Among them, the top 5 frequently used descriptive items were subject, data, overall description, source and data production information, which played an important role in user relevance judgment. Then this study identified the combination of descriptive items with high utility and found that users' use patterns of descriptive items were diverse. Compared with making a judgment with "relevant" result, users often needed less information to achieve a high level of confidence when making an "irrelevant" judgment. This study also found that the descriptive items with high utility include source, data, use and evaluation, and data production information. It is determined that user data literacy and data utilization purpose were the influencing factors of descriptive information utility, and the effects of the two factors were preliminarily analyzed. Based on this research, the paper put forward some suggestions for improving agricultural scientific data metadata and scientific data sharing. In the future, this study will be repeated in groups with different academic backgrounds and data literacy levels, so as to enhance the generalization ability of research conclusions and construct a more effective structure of scientific data descriptive information.

    [Purpose/Significance] Against the backdrop of an accelerating population aging trend, the integration of big data and intelligent services in multimodal healthcare and eldercare has become pivotal for enhancing the quality of medical and eldercare services. However, existing knowledge service systems for big data in healthcare and eldercare face challenges such as difficulty of integrating multi-source heterogeneous data, the absence of cross-organizational sharing mechanisms, and passive service models. [Method/Process] First, a cross-domain aggregation method is proposed for multi-source heterogeneous medicare big data, including: 1) A method for constructing a clinical, key-feature-based medical case knowledge database. It extracts and categorizes critical features from electronic medical records using natural language processing (NLP). 2) A natural language processing-based cross-domain disease risk factor mining framework. It identifies risk factors from social media via topic-enhanced word embeddings and clustering techniques. 3) An adaptive pointer-constrained generation method for medical text-to-table tasks. It leverages the BART architecture to transform unstructured medical text into structured tables. Next, a knowledge discovery method based on multimodal medicare big data is developed, including: 1) A medical decision support approach integrating case-based reasoning (CBR) and explainable machine learning. It aims to enhance diagnostic interpretability through ensemble learning and case similarity analysis. 2) A large-scale medical model-driven knowledge system. It utilizes multimodal data pretraining and domain adaptation to support the entire diagnosis-treatment process. 3) A personalized recommendation method based on temporal warning signals, generating precise intervention plans via collaborative filtering and dynamic updates. Finally, a smart service model for full-cycle evolving needs is constructed, including: 1) A health information supply-demand consistency matching framework combining deep learning and clustering techniques; 2) A multi-level, cross-scenario health demand and behavior dynamic modeling approach. [Results/Conclusions] The proposed methodological framework significantly improves the efficiency with which medicare big data is integrated and the capabilities of its knowledge services. Key outcomes include: 1) Enabling disease risk prediction and personalized interventions through deep integration of cross-organizational, cross-scenario medicare data via multimodal aggregation and semantic alignment. 2) The CBR-ECC model and WiNGPT large medical models enhance the interpretability and full-process coverage of medical decision-making. These models improve the accuracy of diagnoses made by primary care physicians by over 30%. 3) The temporal warning-based recommendation method increases the dynamic update efficiency of health interventions by 40% and user satisfaction by 25%; 4) Dynamic health demand modeling reveals core pain points for chronic disease patients, providing a basis for precision service strategies. This research provides the theoretical and technical support for developing a proactive health service system that is both data-driven and human-machine collaborative. This system will, advance the implementation of the Healthy China strategy and innovation in aging population governance.

    [Purpose/Significance] Genealogy resources are huge and precious historical and cultural heritage. However, in recent years, the value of genealogical resources has been ignored or mis-estimated by the public. The number of related research papers is small, and the practice of augmented reality (AR) application in public libraries rarely involves the public service of genealogy. The published papers and practice of knowledge service of genealogical resources are the cornerstone of this research work. The purpose of this study is to give dynamic cultural value to genealogy resources in public view by exploring the innovative mode of genealogy resources in libraries. [Method/Process] This study investigates relevant domestic literature and work practices, as well as the practice of domestic and foreign libraries using AR to carry out public knowledge services. This research is based on the characteristic genealogy literature resources of Shanghai Library, and the work is based on the digital humanities construction such as Chinese genealogy knowledge service platform, including the construction of "Chinese genealogy knowledge service platform", and the mining and sorting of genealogy information, and the construction of "human name standard database". The theoretical source of this study is that genealogy and surname culture construct each other's value, and they show the value of genealogy resources from the perspective of surname culture. Finally, this study completed the practice innovation of public knowledge service based on genealogy resources in the East Library of Shanghai Library. [Results/Conclusions] Through the practice of "AR surname wall", Shanghai Library, according to our own characteristics of knowledge popularization, provided diversified knowledge services, technology and art integration and obtained the beneficial experience. We found that the existing service is too dependent on technology and artistic effect, did not solve the problem of readers superficial reading, and there is a lack of knowledge service. Based on the practice of public knowledge service of genealogy resources and digital technology, Shanghai Library provides insights into giving cultural value to genealogy resources, has made an innovative attempt in public knowledge service, and made progress and development of the popularization of genealogy knowledge and genealogy culture. In the process of practice, a lot of useful experiences have been obtained, and some problems are still yet to be solved, which not only makes more people realize the cultural value of genealogy resources, but also helps us understand the development of library resources boosted by digital humanistic technology, and the breakthrough of some exhibition items of the East Library of Shanghai Library on traditional exhibitions.

    Intellectual Property Protection of Scientific Data in the Algorithm Era: Factors Influencing Service Quality and Optimization Strategies
    XU Yue, XI Zijie, PAN Chao
    Journal of library and information science in agriculture    2023, 35 (11): 23-39.   DOI: 10.13998/j.cnki.issn1002-1248.23-0483

    [Purpose/Significance] With the advent of the algorithmic era, libraries' information delivery channels have shifted from offline physical entities to online digital platforms. This transformation has brought about significant changes in the way users access and utilize scientific data. The frequency of use of scientific data has increased exponentially, as more and more users rely on data to support their research, education, and innovation activities. The huge demand and application of use of data poses challenges to the development of libraries, among which the service guarantee of intellectual property rights (IPR) for scientific data is becoming a key factor affecting the development of digital libraries. IPR is a legal concept that protects the ownership and control of data creators and providers over their data. It also regulates the rights and obligations of data users and re-users. Therefore, this study aims to explore the influencing factors and optimization strategies of libraries' IPR service quality for scientific data. [Method/Process] To achieve this goal, this study used a questionnaire analysis method to collect data from a sample of 252 individuals belonging to a highly knowledgeable group, such as researchers, academics, and students. These individuals are the main users and producers of scientific data, and their perceptions and expectations of the quality of IPR services by libraries are crucial for improving the service. The questionnaire consists of four parts: demographic information, IPR awareness, IPR satisfaction, and IPR improvement suggestions. The reliability of the questionnaire factors is between 0.724 and 0.913, indicating a high level of internal consistency. The validity of the questionnaire is verified by confirmatory factor analysis, which shows a good fit between the data and the model. Based on the data, this study conducts a path analysis to test the hypotheses and obtain the results. [Results/Conclusions] The results show that the following factors have a significant positive impact on the quality of libraries' IPR services for scientific data: the implementation efficiency of policies and regulations (beta=0.326, p<0.001), talent team building (beta=0.274, p<0.001), the data management technology (beta=0.211, p<0.001), the diversification of service models (beta=0.358, p<0.001), and the number of data IPR sharing agreements (beta=0.329, p<0.001). These factors reflect the importance of improving the legal, human, technical, and organizational aspects of libraries' scientific data IPR services. Based on the findings, this study proposes five optimization strategies for libraries in scientific data IPR service: strengthening the implementation of policies and regulations, improving the training and motivation of talent teams, upgrading the data management technology, innovating the service model, and increasing the number of data IPR sharing agreements. These strategies can help libraries to improve the quality of their scientific data IPR services and meet the needs of the users in the algorithmic era.
